Copland DRC205 digital room correction

Tbg, I know what you mean. I still have reservations about another box and cables in the signal path. However, most of my listening is using cd as a source so I figured another D/A conversion in the chain would not be sacrilige. Right now I have the DRC205 installed between my backup preamp (Manley Shrimp) which doesn't have a tape monitor loop, and the Linn Numerik DAC. The Manley does not have the resolution of my VAC Renaissance so if and when it ever returns from VAC I will have a better understanding of any signal degradation. Right now, I would say it is minimal. The VAC has a tape monitor loop so it would be easy to switch the DRC205 totally out of the system if signal purity was deemed paramount.

Amy more updates on pro's and con's of this device??

I sure wish I could specify the range I wanted to change. It would really be useful if you could set parameters to cover a frequency range like the bass, say 200hz down. I am not thrilled with what it does through the mids and treble. The gundry dip filter sounds artificial. I've heard speakers that are engineered that way and this filter does not produce that effect to my ears. I still find it educational. Factory support is non existent which is another problem.

This morning I received a response from Copland to my question of microphone orientaion during analysis. The instruction manual is not clear as to how the mic is to be oriented during the analysis measurement. I assumed it to be an omni mic and held it in the verticle position. Copland states it should be held/placed so the mic is pointed directly at the stereo center of the speaker system. I will repeat my measurements using this setup and report on the difference.

Rhljazz,

I have a Tact 2.2 XP and interestingly have the same issues regarding what the unit does in the midrange on up. I have been nagging Tact about putting in a frequency correction cutoff for some time, and they supposedly have actually put that in a software update coming soon. Like what you mentioned, the correction in the bass (up to about 400Hz or so) seems very good, and the unit is consistent with the measurements in this range, but above that, it does some weird stuff. I also can't get very consistent measurements when I take them at different times. The corrected response seems kind of hollow to me. What does the corrected response sound like to you?
