Someone should kick me in the keester


No matter how much I know and learn about audio, I can still be completely oblivious to some of the most basic things. Today I discovered a new dimension to that fact.

For quite a long time I've been complaining (privately) about the lack of detail, imaging, and overall clarity my system had, in spite of the quality of its components. I spent a bit of time swapping tubes, changing interconnects, and adjusting the speaker position without a great deal of success at cleaning up the sound or providing a solid soundstage to my satisfaction. While most of my friends couldn't hear the problems I described, I certainly did and it lead me to think that this might be as good as it gets.

A few weeks ago I decided to order some parts to build the Max Rochlin memorial digital cable, partly because I needed a project to keep me busy, and because it was the only cable in my system I had not yet replaced. I finally got around to building it this morning (for those that are thinking about trying it, it took me about an hour or so) and discovered after installing it that I had an entirely new audio system. The soundstage was right on the money and rock solid, the music was clean as a whistle (even through Moussorgsky's Pictures at an Exhibition), the bass tight, the midrange a thing of beauty, ... I could go on.

Anyway, it turns out that my suffering for the past year or so was due entirely to an inferior digital cable and nothing else. I had been very skeptical in the past about the differences a digital cable could make (bits is bits?), but I now stand both red faced and enlightened. I'm not entirely sure that I understand the physics behind the change I made, but it does seem that there are things about digital transmission that I need to brush up on.

Anyway, if confession is good for the soul, then let me be the first to give my spirit a lift :-).

For the record, the system is mostly CJ (17LS, Premier 12's, DA2-B DAC) with a Pioneer DVD as a transport.

Sean: It is a loose adaptation of a concept shared with me by Richard @ Vantage Audio. Their design (which I do not feel comfortable sharing) is of course much more refined than this "wing it" cable, but I really cannot thank Richard enough for his guidance on this project (I really enjoy his "out there" thinking). Oddly, I received an email which stated that other OTA user's had benefited by making the "Cold" lead a bit longer (just the opposite), but this did not pan out in my setup. Yes, I suspect that this is all system dependent and my intention was only to point out that one should not "limit" themselves when designing a cable. I don't feel that we really know enough about this "whole thing" to do so @ this stage in the game. Based on the EE comments that I have read @ AA the OTA cable should not function as it does, anyway, but it does in that it provides full frequency response from the LF's to the HF's (other 26 gage copper/Teflon cable that I have experimented with does not). Go figure. If three people were to "share" one of the kits @ $200 a pop, they would receive enough cable/RCA's to make up a single pair of 10' speaker cables and a set of 1.5 meter (or longer) analog IC's (each). I think that you would get a kick out of this product in one of your lower powered systems (don't know if I would want to pump 1000 watts through it though:-).
Dekay, the OTA worked great with the pass X350 if you like ss. No problem pumping out 350 watts. Sean, I would urge you to try the OTA. Not much to lose. With all your systems, I am sure you would find a home for it in one of them.
What is this "OTA" and where can i read about it ?

As to "low powered", the only system that i have that somewhat falls into that category would be my "antique" Marantz 8 (30 wpc). That amp may be going out the door soon in a trade ( of some type ) though. A local Marantz collector wants it, so who am i to deny his collection : ) Besides, it is very clean and does deserve to be "preserved" in his "Marantz Museum". Not sitting in my cold, dark basement.

Boy, how i wish i had the money for a TDR ( Time Domain Reflectometer ). This device can tell you just about ANYTHING that you wanted to know about a cable in a matter of moments. Then again, i don't happen to have $35K - $50K just laying around at my disposal : ( If i did, you can bet that i would be building cables professionally with very detailed specs to back them up.

With that point in mind, i have to wonder how many cable "manufacturers" ( or should we call them "re-packagers" ??? ) actually have "real" test equipment and make use of it ? I know that Ray Kimber does but as to any others, who knows ???? Sean

Sean, read the "Sakura Systems OTA Cable Kit" thread. 160 feet of wire, enough RCAs to put together 3 sets of ICs for $600.
I have seen the other threads about "OTA cable kit" and have not seen anybody give a website for it. Can someone tell me where to find them. I am extremely curious after reading many threads on it. Does it have a particular sound? Is it better for bright gear or to bring some life into a system?
