Rives PARC or Tact 2.0 AA for room correction?


Hi

I am looking for an analog room correction system and am looking at a used Rives PARC parametric EQ and Tact RCS 2.0 AA (with analog boards included) which were offered to me at similar prices.

I am quite happy running a pair of XLR interconnects straight from my CD player to my Preamp and have no intention of adding any DACs to my system.

However the advantage of getting the TACT is its versatility. I also suspect that it may be easier to set up.

Would the analog connections offered by the TACT be comparable to the Rives in terms of sound quality?

As I have no ability to trial both systems in my home, any advice is much appreciated.

I used a Tact RCS 2.0, with all available input/output board options.
First, if you are looking at the factory refurbished RCS 2.0, as I did, forget it. There is a 2.0s version of the 2.0 that samples at a higher frequency than the 2.0 The 2.0s is 192khz and the cheaper 2.0 is 96khz. The 2.0 is just not transparent enough to be effective in a resolving system. It provides some benefits as a room correction device, but seemed to remove some air and high frequency resolution in my system. The resulting sound produced an improved bass response, but seemed to lack the detail and transparency that were present without the unit.
My understanding, from discourse with the Tact Audio user group, is that the higher sampling rate 2.0s resolves some of the 'detail' and 'transparency' issues.

As far as configuration goes, the Tact has a reasonable DAC, but it didn't better my MF A3 24 upsampling DAC. So I ran transport - Tact Digi-in - Tact digi-out - DAC.

Some people are also using the Tact as a preamp, I tried this but it didn't work well for me.

If I were to get back into the room correction game I would probably give the Rives unit a spin. It approaches the problem from the right perspective, that is, deal with the issues (bass response) and leave other areas alone.
Mr. Rives,

I appreciate your detailed reply and found it quite topical to my concerns.

I can also appreciate the introduction of digital artifacts (you mentioned ringing) with FFT filters (I've studied/designed such devices under Dr. Paul Horowitz). Still, one must weight the impact of such distortions against the larger issue of the room's corruption of the time component of the signal; for me, it is not hard to imagine such artifacts ultimatelly falling into the noise, particularly if the system is highly adjustable (as the TACT is).

At the end of the day, however, I suppose I'm still stuck with the inevitable home audition (you see, I am quite lazy :-). I only wish audio dealers were more receptive towards carrying such products, so I could give the different approaches the acid test: listening to them.

Again, thanks for your reply.

Best,
If you're interested in an analog EQ, then the TACT doesn't qualify. It is a digital device.
