I borrowed one from a polish distributor. Unfortunately we have had problems with establishing communication between the TacT and my computer, so I was not able to test its room correction features. However, I used his digital pre-amp capabilities for over 2 weeks and it easly bettered my Krell KRC-3 (inserted it between my CDT and DAC; KRC-3 was removed) .
As it turned out, when it was shipped to Danemark for repair (the distributor thought that something was broken), someone changed something is one of his sub-menus. I will be evaluating it shortly once again.
