Do Interconnects need to "warm up"?

No to the battery DIY thing...you need an Anode and a Cathode wire for each one running inside the cable bundle. It expediates the dielectric warm up/breakin effect. In other words, the cable is always ready to go full throttle with no warm up or lengthy breakin process. They still need about 48hrs bur in however, despite what they say. The PC's are superb for digital gear, but for all other applications there is one better than MIT...experience and tons of cash went into my decision so don't even start!!

I bought some midrange AQ balanced cables and they sound somewhat better after a couple of weeks. I measured them and they sound exactly 32% better than when new (I used a measuring cup). Also...I don't care what any "technical" smarty pants says...I'm duct taping little batteries to everything.

That's the ticket! Yeah, batteries...I have some special audiohile edition batteries for sale designed by Professor Lipschitz from We Hosem Inc. Correction, I of course meant to say there are "none better" than the MIT PC's for non digital applicaions IMHO:O) FYI, I found only a 29% increae in efficacy in the AQ balanced cables after a couple weeks, but it did improve to 35% by week 3! Of course I used a special automated tube based measuring device with zircon encrusted contacts for minimal experimental error. It's always in the details...let me know about the batteries.

Whow i didnt know that.

I read someplace that Eric Johnson claims to sense different tonal characteristics in his guitar sound when comparing various brands of 9 volt batteries in his effects boxes. So there. And, interestingly, since I'm not actually wiring up all these batteries to the cables, I can use any battery I want...they can even be dead and thus require NO break-in...I'm cramming little fake wire leads under the cable plug casings to lend an air of legitimacy to the whole thing. I really think the sound has improved.
