Tact Pre Amps

The Tact is not a easy to use gear if you want to get a good result... you will need to spend a lot of time to find the best settings.
Also the analog I/O are definitely bad, forget them if you want to get a good treble.
I think the 2.2X is better as there's a way to correct the signal only below 350Hz, you can't do that with the 2.0S and from my experience correction higher than 350Hz are not interesting... a few Echobusters panels are way better.

The Tact's A/D and D/A board get a LOT better after Aberdeen Components modifies them. My XP has all the mods Aberdeen offers, including power supply, motherboard, A/D boards, and D/A boards. They put the XP in a totally different class vs. stock. To note, with the XP you dont have to use a computer - everyhting is done inside the unit - although you can use a computer, and you will want eventually if you want to fine tune your settings.....

The XP is a far superior piece, and I've owned the 2.0s, 2.2X, and XP. All processing is done in real time instead of waiting eons for a laptop to do it. And, TacT is actively involved in R&D and improving the functionality.

My 2.0S was totally modified with external wordclock, top quality diodes and rectifiers, blackgate NX etc...
The A/D and D/A boards sounded much better after the modifications but still not very good.
