It might seem trite to quote Shakespeare, but many of his quotes have found their way into the daily vernacular and parlance of the common man. His incomprehensible plays written in archaic English were foisted upon me against my will in high school. Like all the algebraic formulas that I had to learn by rote , the still developing mind of a high school student knew that this would prove to be absolutely useless in adult life.
A lot of people quote Shakespeare without knowing the origin or even the meaning of what they are saying. This leads me to believe that had ol' Will had been born in modern times, he would be a audio critic at The Absolute Sound or something. If he had been born in Canada, he would be a Tory politician or maybe a an artist designing our funny-looking money.
Don't get me wrong, I am in no way criticizing Shakespeare, after all his works have endured for centuries. My electronics instructor, for instance, was way more full of shit, preferring to ramble on about his TRS-80 computer and obsolete ham radio. Perhaps his Korean war flashbacks made him a little nutso, and this might help explain why I still don't know anything about how to fix your TV. I did make it a point however to memorize Ohm's law. This would prove useful in later life.
As a young audiophile I hadn't yet acquired a lot of common sense and was easily impressionable. I would listen to a lot of nonsense from older audiophiles. It took several years, but it eventually dawned on me that things are not always what they seem. Maybe I should have paid more attention to the laws of physics in high school, eh ?
The early days of audio were a different time. Everything was stuck in the analog domain and we took manufacturers at their word. Even the audio gurus at the local audio shop did not have all the answers. That is probably because we didn't have the questions yet.
I'm sure that there are many among us who are still kicking themselves for not figuring out that good quality interconnects and engineered speaker cables would be the actual arteries of a quality sound system. Everyone was using plain old lamp cord back then with nary a second thought. Many of us still think that we could be millionaires had we figured this out early on. Monster cable did, but the extremely low capacitance of their early speaker cables would gleefully blow up amplifiers without warning. Their legacy lives on at Best Buy who sell their overpriced "power conditioners" that also have a tendency to blow up. Plus ca change....
We would use the crappy interconnects that came in the box with the components. We used to call them patch cables back then, and it was a given that they would soon fail. The cheap molded plastic would break and the connection severed, or even more frustrating, become intermittent. I am still astonished that these pieces of junk are still being manufactured today. Even the crackheads who steal extension cords from your backyard for the scrap copper don't want these ubiquitous pieces of red and white shite.

Then, as now, there were many companies who were more than willing to prey on the naivete of burgeoning audiophiles. There were some mighty dumb tweaks back then, and they all hooked up into the tape monitor loop. DBX made a line of expander/compressors. These black boxes purported to increase the dynamic range of an audio system. What they did is induce a kind breathing into the sound, as if your amplifier had asthma and was hooked up to a little respirator. These units were not cheap either.
My all time favorite however was the outboard reverb unit made by (who else) Sansui. The San-sewage gizmo was also meant to be hooked up in your tape loop. It had a large spring inside and the audio signal would literally
pass through the spring. You can't make this stuff up. My buddy had one and we spend countless hours amusing ourselves by hitting the top of the box with our fist and listen to the resulting
boing-oing sound coming out of the speakers. It was hilarious. What wasn't hilarious was that it was marketed as a serious audio device and was quite expensive.
Some early car radios had also experimented with this technology where a spring was attached to the speakers. Every time the car would hit a bump, that hilarious boinging sound would be produced. It was probably invented by the same geniuses that gave us the under-dash 45 RPM record player. Cars built like tanks, riding on bias-ply tires and not equipped with air bags probably benefited from not have jarring sonic distractions. One was busy enough looking for the ashtray and lighter. Ah, the good ole days.

The years went by and I became an avid reader of Stereophile magazine. I also drank a lot of their kool-aid. As mentioned in a previous post, it took a while for my friend at the Linn audio shop to convert me to Linnism. He let me spin my wheels while happily selling me used non-Linn components.
It was already a given in audio circles that the Linn LP-12 was the benchmark for turntables. Linn turntables would work best on a piece of furniture that did not store low frequency energy ( ie massive and heavy) and they worked even better if they were wall mounted.
It was also rumoured that Ivor Tiefenbrun invented the speaker spike, but I have yet to conform this as most search engines are frustratingly opaque and seem most efficient at finding bullshit.
If you will allow me to go on a tangent, I just wanted to point out that after reviewing my stats, it seems that the vast majority of readers here are Linn owners, so I might be preaching to the choir in many instances. That suits me fine, it's like talking about cars with car guys, you are speaking the same Linn-go ( pardon the pun, I couldn't resist). Or like two-wheeled road warriors comparing Lycra outfits and how they pertain to butt-hurt all the while convinced that they could do the Tour de France tomorrow....er.... scratch that one and forgive me for leaving images of men in spandex etched into your brain.
When I first started writing this blog, I began in my own backyard but soon found out that we Canadians are an angry bunch. We seem to have a reputation for being polite. While we do enjoy our donuts and our Ski-Doos, some Canadians seem liked they might have a had an encounter with an angry moose ( it actually does happen).
I posted this blog into the forums of a Canadian used audio site that rhymes with Shmuck Audio Tart, and was soon besieged with angry comments. None more so than by the moderators themselves. There were a few people who scoffed at my lowly LP-12, but these angry moderators ( don't they have a job or something?) were threatening me with " sanctions". I wonder what they meant, Perhaps they were going to contact Tim Horton's and have me banned for life and leave me unable to ever purchase donuts ever again.
Angry moose aside, the Brotherhood of the Linn understands one thing; Linn components do not like tweaks. I eventually accepted this and life has been easier, and I don't have to worry about charlatans anymore.
Getting back to the audio kool-aid, as I said my buddy at the Linn shop just let me do my thing, and he knew full well that I would eventually come around. He sold me all kinds off oddball CD players. I had a California Audio Labs which I soon traded in for a Sugden.
I bought all manner of gizmos as dictated by the writers at Stereophile. I purchased a Theta Time Linque Conditioner, which was supposed to re-clock the digital stream and eliminate jitter. I bought a Townshend Audio Seismic sink (it actually made the Sugden sound a little better)
One of the aspects of audio that seemed to get a lot press was anti-vibration. This makes sense to a certain extent, so I eagerly read about cones and spikes. I also the perused the design parameters of extremely expensive audio racks, that claimed to have vibration elimination properties and tune components.
I already knew how to weld and had access to a metal shop. It wasn't so much cheapness on my part as the fact that I knew I could build my own audio rack . I thought that I could make it sturdier and I could also make it custom fit the components that I had. I spent several years making many different racks. I experimented with custom machined cones, included spike-supported shelves, filled hollow spaces with sand and even tried suspending shelves from stainless steel cables. Some of the racks looked really cool, some ended up in the alley from where the junk pickers in beat up GM pick up trucks would grab them.
In the long run, other than the decorative appeal, I could not hear any discernible differences in sound in these racks. I didn't know if the end result was better or worse, and with all that futile welding, I probably wasted enough Argon gas to fill the Hindenburg. All this tweaking was starting to stress me out.
I did make some custom furniture pieces for my friend's audio shop. They were purely store fixtures and aesthetics were the main concern. I soon realized that I could put my fabrication skills to good use and maybe indulge in the time-honored tradition of bartering. It seemed more productive than making audio racks for myself and either throw them out or re-fabricate them into BBQ stands.
After some wheeling and dealing and equipment trade-ins, I eventually took my friend's advice and made the jump to an all-Linn sound system ( as mentioned in a previous post).
I set up all the gear on my overly complicated audio stands. It sounded great of course, but I still wasn't at ease. I still had a bad case of
tweakophilia and maybe a touch of what the writers at Stereophile so aptly described as
audiophilia nervosa.. Like in that Little Willie John song I'm Shakin' where he shouts "I'm nervous!" ( hey you kids, Jack White's I'm Shakin' is a cover of a very old song, and get off my lawn while we're at it).
My Linn mentor was still admonishing me and told me to stop messin' around and not worry so much. I couldn't leave well enough alone, but he was soon to be proven right.
The first thing I did was put the Linn Genki CD player on the Townshend Audio Seismic Sink. I thought that maybe my polarity was reversed or maybe I had eaten some bad cheese and was hallucinating. I checked the cheese for greenies and double checked all my connections. All good. I removed the Seismic Sink and the difference was palpable. That fairly expensive gizmo made my CD player sound worse. Much worse. I eventually sold it to some uber-tweeker who would go on techno-rants about Black Gate capacitors or something every time he saw me at the coffee shop.
I still had some MIT speaker cables hanging around, some of you might remember those, they had a big mystery box glued onto the wire in series . To this day I don't know what was inside those boxes. MIT 's literature mentioned something about a network, but it could have been dead squirrels all mashed up in there for all I know. I procured some Linn banana plugs and soldered them onto the MIT's. I hooked them up to my LK-85 but something wasn't right.
At the shop where I worked several years later with the owner who would flip out at the mere mention of Linn, I casually mentioned absolute phase. His reaction was not unexpected and his diatribes made me laugh. It was not rocket science however. The Linn LK-1 and Kairn preamps had a reverse absolute phase, so all that was required was to inverse the polarity on the speaker cables( at one end only)
So after a careful polarity check, the MIT's were hooked up. It sounded weird, Muddy and no sound stage. I hooked up the Linn LK 400 speaker cables and everything fell into place. I got pretty much the same result when I tried MIT interconnects. Dang. I hooked the Linn interconnects back up. I still had that weird emotional attachment to the MIT's ( because they were expensive) but they were now virtually useless. I sold them on one of the used high end audio sites, you know the kind. You exchange 40 e-mails and are expected to solve the buyer's technical conundrums ( not unlike selling old bike parts on craigslist).
Still not completely satisfied with having all Linn components, I tried to tweak the speakers. The Linn Keilidh's had an optional composite base that was available. It was a brilliant idea because they made the speaker's footprint wider and were supposed to tighten up the bass and the imaging ( which of course they did). Not completely convinced, I removed the bases from the speakers and took some measurements.
I went to a large industrial metal supplier and ordered large lead slabs in the same dimensions as the pseudo-granite bases. They had immense slabs of lead and would simply slice off a slab like a large salami. The one foot square slabs of lead must have weighed in excess of a 100 pounds each. I took them home and drilled the necessary holes for mounting and for spikes. None of my friends seemed to be available for heavy lifting, so it took a little bit of maneuvering.
I fired up the stereo eager to hear the effect of my new, possibly toxic bases, smug in the knowledge that I might just have outwitted the engineers at Linn. It take long to find out that I was wrong. I was suddenly confronted with excessive, wooly bass. It boomed and chugged, and try as I might to convince myself that this was good thing, it soon started to annoy me.
I also wondered about the long term effects of having large, untreated slabs of Lead sitting in my living room, but it wasn't like I was licking them or anything. Back in the day, teachers in the high school science lab would give us blobs of mercury to play around with, so a few lead fumes didn't seem to be a problem to me. It's just that the sound sucked, and I soon removed the lead slabs and re-installed the original Linn ones. I got 10 cents on the dollar at the scrap yard for the lead.
It finally dawned on me that Linn components don't interact well with tweaks. I finally took a my friend's advice and just enjoyed the innocuous looking metal boxes with the funny logo.
The only tweak that we ever did to Linn, which I learned first-hand when I eventually started working at the Linn shop, was to disregard the speaker placement parameters indicated in the owner's manuals. For example, Linn suggested that the Keilidhs be placed 4 to 12 inches from the back wall. This went against years of experience and listening to all types of speakers. We would do the "tune dem" . All speakers need to be tuned to a room, but Linn has a very specific methodology on how to go about it. Most of the Keilidhs that we installed in customers' homes tended to be be in the 20 to 24 inch range from the back wall ( Kabers and Keltiks even more so ).
The only reason that we could come with for this discrepancy was the difference in construction in homes in the UK and homes in North America. Rooms tended to be a little bigger in North America and cheap-ass drywall was the material of choice for walls. This is probably why most people in condos hate audiophiles and want to puncture their speakers with large screwdrivers.
We did install the supplied spikes on all speakers but not for the reasons that are usually accepted as common wisdom. Without opening a can of pointy worms, and keeping in mind that physics bored the ass offa me in high school, spikes are a simple way of coupling speakers to the floor. The motion of drivers moves cabinets and a good anchor point is essential. The taller the speaker, the more the bass driver will make it act like a lever, so it is necessary to spike those things nice and deep into your hardwood floor. This does not always end well ( see previous post The Wife Acceptance Factor).
To yet again quote Shakespeare " there's the rub". Spikes and cones are not de-couplers nor act like diodes. They are actually very efficient couplers.
I learned this over time with lots of empirical evidence to support the results. Those little suckers concentrate vibrations into one tiny point almost amplifying those pesky acoustic waves. Similar to what a sports cleat does. Other than mangle other players' hands, they grab the earth and transmit that energy.
I don't want to start a complicated debate, but I proved it to myself yet again recently. I had some cones lying around and decided to install them under an older Mac mini, the ones that still have a CD drive. Even die-hard bachelors are familiar with washing machines that do a spin cycle with an unbalanced load. When one inserts a fairly scratched CD into the Mac's drive and proceeds to rip it to iTunes, the ensuing vibrations are like that washing machine. The cones that I had installed under the Mac transmitted those vibrations so accurately that I could have tuned a guitar with the resulting shaking that was induced into my desk. The whole thing was happily oscillating along at the same frequency as the Mac's CD drive.
One final note about equipment racks. I recently attended a hi-fi show a local hotel and one thing that struck me was the the expensive racks that were used for the displays. These racks are marketed as essential audio components and priced accordingly. The stratospheric price tags on some of these racks was astonishing, considering the build quality.
Knowing a thing or two about metal things, I personally thought the quality was lacking. Some were made with sliced chunks of aluminum extrusion ( pardon me British friends; Ah-loo-min-eeum). Extruded aluminum is relatively inexpensive and judging by the way some of the pieces were cut maybe they had trained some monkeys to operate a horizontal bandsaw. These racks, who shall remain nameless, were retailing in the 3000 dollar range. Another overpriced rack was made out of ready-rod, otherwise known as threaded rod, the type that one can buy at any Home Depot and it was well into the 1000 dollar range.

The only advice that I can offer on audio racks is buyer beware and keep in mind that you have to assemble these racks yourself. At least they won't make you walk a maze and try to sell you meatballs like IKEA.
These days my Linn system sits on an old mid-century teak thing that I found in a movie prop surplus shop and the only tweaking that I indulge in vacuuming around my speakers. I haven't welded anything together in a while, and that's not bad thing, because with all the toxic fumes, I would have probably ended up unable to add two and two together from the brain damage.
