MIT's not good for tube components?



I was at a hi-fi store the other day and started chatting with the owner regarding improving my system and such. We got to the subject of cables, and I mentioned that I was using MIT 2 biwire for speaker cables and MIT 330 shotguns for IC's. He quickly mentioned that I needed to get new cables, because MIT's weren't good for tube components. I wasn't sure if he was trying to get me to buy cables from him or if in fact MIT's are deficient for tube components.

Any comments regarding this?

Also, if you have any recommendations for speaker cables and IC's that may mate well with my system, I would appreciate them.

My system:
Vandersteen 2ce sig
Eastern Electric Minimax tube CDP
TAD-150 sig tube preamp
McCormack DNA-1 deluxe

thanks for all the info guys. hmm, looks like i'm gonna have to do some serious research on cables.
I just downloaded the Purist brochure. Web site opposite in quality to the MIT. Drew, I am personally a real big fan of accoustic zen. I also like the audioquest toslink cable. Check out all three web sites. With any of the above you will find lots of praise here on audiogon. I do intend to explore the Purist line. Oh, did you know about the cable lending library at www.fatwyre.com?

It is a bit hard to find at their web site. Call them.
I started buying equiptment in 94 and since I bought tube I was told never to by MIT cables. I still to his day never know what the reason is. Hope someone can elighten us ?
Hi all. The way I heard it it is this: all cables that use network systems (MIT) do not sound good with passive preamps (tubes). I use my MIT's with the preamp set in active mode and they sound great. The system goes south in passive mode. Also, MIT does make speaker cables optimized for tube power amps.
I'm very happy using MIT Shotgun S3 speaker cables with my tube hybrid integrateds.
