But even if the product had exist, it would not have have mulit channel S/PDIF input, like 4xS/PDIF, similar to a modified Oppo from Custom HT.

Yes, it is old but presumably there was some development work accomplished for even the prototypes.

And the preamp had 4xS/PDIF outputs while the power amp had 2xS/PDIF inputs.

Classe, Krell and Sim don't have RC either. And yeah, he's biased, but Boz at Tact really talked me out of having any interest in using PEQ in a processor.

Having said that, not having RC will be a deal breaker for some.

Read the feature list for Sim Audio CP-8: http://www.simaudio.com/mooncp8.htm

Same for Classe SSP-800: http://www.classeaudio.com/delta/detail-ssp-800.htm

The Classe isn't automatic but I don't see that as an issue. Knock down the nastiest peaks with parametric EQ and leave the rest alone.

FWIW I suspect room correction was something some marketing type came up with to sound different from EQ. Either way it won't fix early reflections and other such room anomalies.

There is a HUGE difference between analog or digital frequency based EQ (parametric or otherwise) and time domain digital room correction as performed (for example) in the Tact. While the results in the very lowest frequencies may be similar that is where the similarities end.

The Tact does indeed deal with early reflections. In fact, that is exactly how it works.

You may want to do some research on how the Tact (and other similar products) operate. They are NOT frequency based EQ systems (tho the Tact does offer that as an add on to some of it's products).

I stand corrected on the Sim and should have caught that knowing it's based on the Denon platform. And yes, as noted above EQ is a different ballgame from RC.

If the TACT and others of that ilk are playing enough with the signal to handle early reflections etc I'd have more than a little concern about the end results. EQ I can accept. The kind of signal manipulation to cancel out reflections well that will take a bit of convincing. Sounds like it would be easier to do much more harm than good. Certainly something that would take a long home trial with a guaranteed return policy.

Either way sounds like I've got some reading to do.

I would never do a theater without room correction. I don't even know of a reference theater without it? After installing my QSC DSPs in my theater, the improvements in dynamics, bass and intelligibility were pretty staggering. The Tact had piqued my interest as the Trinnov / ADA combo. Can't wait to see how these pan out.

There are more than a handful of [op amps] that sound so good that most designers want to be using them as opposed to discreet transistors. Dave Reich, Theta 2009

I may have missed something in reading the TACT technology info but it looks like they are correcting entirely in the frequency domain instead of time domain. Basically an equalizer flattening the room response or modes but doing nothing to cancel out early first reflections from floor, ceiling and sidewalls that arrive just long enough after the direct signal to smear the sound. Just as well, this kind of thing is better handled by diffusers IMO.

I put some very good preamps in front of my ATC active 20s/REL sub combo that's in a difficult room that I can't treat. They all disappointed, the Tact Mini w/its RC did the trick.

If I'm reading correctly what the TACT or any of the other pieces with RC are doing is something that's difficult to correct with treatment. Room modes are driven by the dimensions of the room. Absorption can be challenging to implement when trying to reduce a low frequency standing wave. RC or EQ can help with this on at least the peaks. Trying to raise a null can be like trying to fill in a black hole, however.

I'm certainly not arguing against the benefits of RC. Just that it isn't a panacea for every issue. If TACT is working in the time domain it certainly isn't obvious from the info on their website. All they talk of is correcting the in room frequency response and the matching of the speakers to smooth the crossover regions. Of course it's entirely possible that they've dumbed it down to protect me from myself.

Les,

Room Correction is not a substitute for conventional acoustical treatments. You have to have an ideal space and room acoustical treatments first in order to get the optimum benefit of TACT. TACT et al simply fine tune what is already improved from conventional room treatments, it is not one stop shopping for ideal freq response and reverb time in a poor environment..

Agreed on the above. Only thing I'd add is that such units can be tremendously useful in rooms that you can't treat, even moreso than the ones you can

Jeff, I think that's what I've been saying, "Just that it isn't a panacea for every issue." and had said previously. RC can smooth out the room response but won't handle reverb, first reflections arriving just late enough to smear the sound and all the other nasties that take proper room design and treatment.

RC does make a nice first step for those for which treatment isn't possible. And it does some things much easier than moving walls to correct standing waves. At least partially.

Of course ideal room can be more than a challenge. Not all of us can go out and have a bespoke room done. Love to do it but I'd have to use an iPod and dock for the next 10 years or so to pay for it. Assuming I stay employed in this administration.

And I'm starting to be sorry I started this fuss even though I still believe Theta is going to have to add EQ or RC to compete properly.

I tried to impress upon the original owners of the company that if they did not offer a "sale" on the Superior II and Xtreme dacs to get guys to buy them in advance, this would happen. Theta would find itself in a position where a single upgrade would cost too much for an owner without the proper dacs. I hope that even though it may not be feasible now, the current owners left open the possibility of adding parametric EQ to the CBIII. This depends of which platform they chose. If the upgrade program to HDMI is a sucess, EQ could be offer down the road. I know they currently have NO PLANS to offer any kind of room correction.

Never become so involved with something that it blinds you.
