Rives PARC parametric equalizer

Passive biamping of my speakers does offer a slight improvement in dynamics (mostly in the bass) and imaging. I am told that using an active crossover would have a more profound effect. This setup allows me to bypass the PARC for the midrange and treble and preserve the dimensionality and lucidity that I believe the PARC slightly messes with.

In the biwire configuration without the PARC, the dynamics and overall imaging are not quite as good but I did not experience the 2D effect and loss of lucidity in the midrange and treble.

When using a full range signal from the PARC, I agree that the effects of different PCs can be heard. At 300 Hz and below, PC choice is less critical in my system.

If the PARC was the ultimate solution, there would be little market for acoustically designed listening rooms. The cost of such a room could easily exceed the cost of an additional amp, cables and crossover.

Have either of you tried the PARC set flat and compared it with the bypass function?

Of course, if you have dirty power then adding any powered device may add complications. My experience is that digital devices seem most sensitive to power...

I don't doubt the test results suggested by Rives, but it is not a real useful test to me. You are still passing the signal though 2 extra sets of connectors and introducing an extra set of cables. My system does not sound as lucid and dimensional in the midrange and treble as when totally bypassing (removing) the PARC. This applies both to passive biamping and biwire setups. Whether this signal alteration is bothersome will depend on the overall system.

At the time I was testing this, the PARC was being fed by an Exactpower EP 15A and decent PC - Von Gaylord Chinchilla. I do not believe power quality is effecting my opinion.

My PARC is also fed by Exactpower EP 15A. I dont know if it may affect PARC adversely. Anyway in this configuration, and to my ears, attentuation of bass boom not withstanding, the PARC is not transparent compared to if it is out of the chain. A good PC certainly helps to close the gap though.

There is another thread at the moment that speculates how mid range can affect bass perception ....perhaps it also works in reverse too...

....all the same I am puzzled by what you both report but I don't doubt your observations.
