Yep, sold the TacT and on to computer-based room correction. Since my primary source is a modded SB, this was a logical direction. I considered the Aberdeen cards and decided against, not as a knock on them or their value, but more because I wanted to go back to a tubed preamp. Being able to get my correction fix at the computer finalized the deal.
There were many factors that went into this decision and it was made over months, not days. I replaced with a Lamm LL2 Deluxe on Tvad4's recommendation and it is a Truly Superior Piece, especially at the price used. With the Sig. 70s it's like a SET preamp.
Even without room correction the sound is better than it's ever been. Once I get the room correction figured, watch out world.
