I just bought a 2.2xp and two 2150 from tact directly and found Boz really helpfull. Great service. Agree that its another ballpark and a steep learning curve,especially for an analog audiophile and none too good w/ computer.However its well worth the hassle as nothing else will give you as much performance and flexibility for the price. Plus you can modifiy the equipement if you want even more liquidity and fluidity.
Tact Pre Amps 2.2XP
For some reason this post last wound up under "Speakers." Go figure. Anyway, I am thinking of purchasing one of these. There's a unit on Audiogon for $3495. Is it worth the investment?
