@unsound I was thinking of getting a hardware based DRC system in the past. I looked at Room Perfect, Space Optimization, Deqx (sp?), and ARC3. I remember Space Optimization was describing setups where you can place the speaker against a wall and have the sound processed as if the speaker was in the optimal positioning away from the wall.
The DRC I will explore will be a software based solution running on my ROON Server (in another room).

A note about the CS3.7 sound now. I am listening to the radio late at night at low volume. I seem to be hearing everything but just lower volume. I think that is a compliment to the speaker and the preamp (which I rave about). In the past, when I used to go DAC directly into the AHB2 I hated low volume listening. I felt like I was missing parts of the sound, not so with the HPA4 preamp. The CS3.7 is an added bonus for late night listening. Reproducing all that the preamp is feeding it.
