I know this is heresy, but...

Shadorne...Rives audio, who certainly are great believers in room treatments, will tell you that low frequency problems can't be fixed this way.

The above comment is my worry exactly...I am sure acoustic treatment is essential and extremely beneficial in a smaller room ....but is it effective in a larger room for below 100 Hz? I don't use a PARC but I have a Behringer PEQ controlling or taming the Sub (reducing room modes). On the mains I use some slight bass shelving (about 3 db) to reduce the bass boost effect from the soffit mount. I don't have much concerns in the mid/tweeter range as all the walls have a roughened surface (about 3 to 4 mm deep) which helps with diffusion, furthermore, the speakers are placed well away from side walls (about 4 feet away, so side reflections are delayed about 8 msec which is almost certainly enough not to interfere with primary signal, using the 5 msec rule of thumb for side reflection and diffraction)

Shadorne, you can look at my new system pics I added 16 linear feet of trapping just hours ago, and I am updating the pics right now.

Wow nice set up - your room looks awesome and I bet it will sound great too once you have it all setup.

I appreciate all the ideas and admire/respect what you guys have done.

You may want to contact Rives or Realtraps. If you buy something from them they'll be very open to advice for you.

Warnerwh, I think that is a good plan but once I take that step I will find myself committed. That is whay I like Audiogon forums...it takes me years to make a change or a decision. I am not a compulsive tweaker and tend to approach everything from an engineering perspective. This is why your advice is so important to me before taking any steps. Unlike many on these forums, once I settle on something, I will likely stick to it for a minimum of 10 years or more.

Well having plenty of fore thought can only help. Btw bass traps are essential and will help the sound of the bass alot. Not only that but the clarity of the midrange often improves dramatically too.

Once you do get the room treatments there's no going back, no way no how.

Can someone tell me if the DEQ2496 connected between the CDP and preamp is worse than between pre and power amp?

I am a little disappointed that, while the DEQ does not add colorations per se, it does add a slight haze to everything. Sound is slightly less clear, less crisp, and a bit more shut-in.

Would it work better in the digital domain vs. analog?
Or is everyone here using it as an analog eq?

Thanks

If you put the DEQ2496 between the preamp and the power amp its A/D will be working with only a few low order bits. The advantage of 24 bit hardware will be lost. You may not like the sound.

The solution to this is to attenuate at the input to the power amp so that the signal going through the DEQ2496 is at a healthy level. Set things up so that the peak level throughout a CD, indicated by the DEQ2496, is about 3 dB below cliping.
