Rives PARC or Tact 2.0 AA for room correction?

The October/November issue of "The Absolute Sound" magazine has an extensive article on room correction, and I believe they review both of these units.

The TacT does its correction in the digital domain, so it has to either get a digital signal from your source component or convert an analog signal into digital. If you use the TacT, the preferred approach is to take the "digital out" from your CD player and either use the DA conversion that is built into the TacT or go from the TacT to an outboard DAC before going to your preamp. Taking the analog signal from your CD player and using the AD conversion in the TacT would be a pretty compromised approach. That is not to say you won't be happy with it, but the TacT AD conversion unit is really meant for accomodating analog sources such as LP and tuner. The TacT AD unit works fine, but its quality is not an engineering priority in the product as the company is pretty much dyed-in-the-wool digital ("We don't do analog" Peter Lyngdorf once told me).

The Rives is all analog, so none of this applies. The TacT is capable of doing a lot more than the Rives, which is limted to three corrections per channel and only in the low frequencies (which is where you need it). That may or may not be a good thing for your application.

I too am looking into this approach. I must say - on paper - the TACT seems superior to the Rives due to the time correction it offers, which should make speaker placement and other room issue less disruptive of imaging.

Rebuttals to the above are welcome, for I am in a similar boat as "acw" -- there are no local dealers for these devices.

Best,
