Is my Salesman telling the Truth?

Try them out yourself. You can through the "Cable Company".
Frankly I own MIT. In my system they performed overall the best. This is very system dependent. So take what your sales rep states with a grain of salt. BTW, I also am in sales and do not put us in the same light. Some of us have scruples.

I'll bet he does'nt sell the ones that suck and has never heard them. Do not buy something just because the other one supposedly sucks. Look at politicians. They always say the other guy sucks, when actually they all do.

Simplicity! They are all great in the right system and they all suck in the wrong one. The final pieces of the system, the cables, are vital and need to be demoed with your equiptment. That is the only way you can be sure.

Yes, cables are system dependent,as my predecessors point out. But; it is funny how, in much of audio, certain brands are highly revered,and command great resale,and certain others ,you have to give away. Although the brand you have to give away may be better. You said this guy was local? If your seriously interested; take home broken in ones/with exchange privilege. Audioquest,and Cardas have great resale value. If you buy them for a good used price you hardly stand to get hurt.This can be said of the other brands /mit & trans.as well.Your dealer is in buisness to make $. Don't "use" him.(As in get his advice, & demo/then buy used.)

Your salesman's advise is worthless because he is totally biased and not at all subjective. I agree that you have to try all the cables in your system before making a decision. I went through it and while it was not that much fun, it saved me a lot of time and money in the long run.

I personally had very little luck with either the Cardas or Tara. With my single post speakers, Transparent Ref XL worked great. I eventually replaced them Nordost Valhalla which I currently have and love.
