I've heard nothing but great things about Tact from industry professionals so I for one am looking forward to evaluating this processor. I want to see how it stacks up to Audyssey and my Denon AVP is getting upgraded to the latest Audyssey in 2 weeks so this is timely.
The trick will be (in addition to actually shipping a product, and making that product reasonably bug-free) if they can get the TacT stuff as easy to use as ARC and MultEQ.
While that DOESN'T necessary sound like a high bar...
I had TacT's room correcting integrated amp in my Viennese flat for a couple weeks in 2001 or 2002. After that, I traded it at the dealer for a bog standard Classe integrated, because the TacT box was just too perplexing. The instructions were awful, the menus confusing, and it was just not a pleasant piece to use. (Also, independent measurements were harder to come by then. There was no FuzzMeasure, and I at least didn't have a calibrated mic. Or any measurement gear except the old Mo-Fi Alan Parsons Sound Check CD and an analog Rat Shack SPL meter.)
That box was, to be fair, TacT's first- or second- generation unit. And used the little screen on the box. (Maybe it had a TV out, but I didn't have a TV so that wasn't relevant to me.)
Also, I think it is a pity the Emotiva box is a pre-pro and not an AVR using TacT's power-DAC (PCM->PWM conversion) technology. A simplified form of those amps was used in the old Panasonic receivers, which were the most energy-efficient AVR's I've seen. One would expect considerable development into output filters for class D amps since then, so what flaws were found in the old Panny XR55* wouldn't necessarily be there with newer generation stuff.
*the measured performance wasn't great, as this site has chronicled. However, I couldn't distinguish it in a level-matched blind test from the separates it replaced - Marantz AV600/Adcom GFA-5800 - on KEF speakers, so it was good enough for me. But for modern room correction, I'd still be using the XR55.
