Tact 2.2x has the $500 Maui Mods (Aberdeen) Power Supply upgrade.
Tact S2150 has the analog board installed
Original Cost of the pair was over $10,000
Sell both as a pair for $ plus shipping (yes, my previous sale fell through, so here they are again)
The 2.2x has analog board and one digital boards installed (presently on the sub output). All you need to add is a transport and speakers (and a sub or two if desired -- but not needed). Original PS, mic and CD included.
In my (pretty good - 16x23x10) dedicated audio room, room correction has made a fantastic improvement, opening up the mids and tightening up the bass on several speakers, including my current YG Acoustics Carmels. I've left my personal presets on the unit (I believe the factory presets are too dark and rolled off for most people's tastes).
Both are in good condition. The 2.2x has a few smudges and light scratches. I can send pics if desired.

FYI, also own other digital input and switching amps (NAD M2 and NCore monos) and while Tact is older technology, IMHO the Tact system holds its own, esp w/ the power supply mod.
