Rives PARC parametric equalizer

Super cool system you have there. I always felt a slight loss of resolution. Your system is all tubed and the application I installed the PARC in was all tubed also. It might not be as noticeable in a solid state system. Ultimately, I made room and tuning changes that satisfied me.
Looking at your room, I would recommend some tube traps to experiment with.

Interesting that this topic has returned. The comments by Rhljazz match my viewpoints on this subject. For a tube-based system where harmonic information and 3D is a strength of the system, the PARC is most definitely going to affect the performance of the system in these key areas.

My comments on using the PARC are here

Not only does the PARC alleviate modes that are untreatable with bass traps, ASC Super Traps in my case, reducing those modes significantly opens up the soundstage and transparency and improves elocution significantly.

I use the PARC and it's the best component in my system.

I find it very transparent and agree with Lenny_zwik that it can open up the soundstage. Getting the bass right has a lot of benefits.

thanks for the comments.

With my room - LP cabinets all across the back wall ( behind listening position) and front right side wall make room treatments / bass traps difficult without major changes.

Using the Rives CD, it would seem that my main bass problems are around 40hz (+8db) and 100/125 hz(+12db). Using a cheap behringer Ultra-Q T1951 parametric eq, it would seem that the 100/125 hz causes the most noticable boominess on most music. reducing the 110hz by 7db has helped quite a lot. Still playing around with it.

What acustic treatments are good for the 100/125 hz area's?
