I like Transparent Audio and have for the last 10 years or so...you can get great deals on 2nd hand cables from Used Cable Co or from Audiogon. You can also try the folks at Paragon Sight and Sound...Larry is great. I think they must be one of the biggest dealers of Transparent and often can find 2nd hand or demo cables of whichever kind you wish. They also can help you determine in the newer versions whether you really need to recalibrate or whether you can do with out. One of the things that TA seeks to do is adjust for the impedance differences between the equipment. Does it work? In theory, yes...all I know is they work, and I have not been disappointed except by their digicable which for reason was just a disappointment. I use Zanden's proprietary i2s cable now in any event. Good luck...don't break the bank as much of the older TA Ref series stuff is absolutely great and can be bought for 25-35 cents on the original retail.
