I have rolled several opamps in the LR, DAC and buffer slots. Try the AD8656 in the DAC section with the AD797s in the LR and see if you like it. Will bring the bass out a bit. But I have to agree that the D1 is light on bass.

I have K701's and they mate very well with my micro stack but on the D1 it gives listening fatigue in about 10 minutes. I think the D1 would mate very well with either closed cans or the HD650's. I had HD600's that sound good but I just sold them because I decided to stick with the K701's.

Rolling opamps. I have replaced opamps before but they just lifted out and the new ones plugged in. The daughter boards that the L/R is on is throwing me off. Does the opamp come mounted like that or is it something I need to put together?

Dual DIP opamps are just plug and play. Dual SOIC opamps need to be soldered to a browndog.

If you're using single opamps (such as the AD797) you'll need to mount 2 of them on a single to dual brown dog adapter.

Well, I am out of my league. You might as well be trying to show algebra to a cat. Well, maybe not that bad but close.

Check my review thread(in my sig) to see what the optimal opamps are. I've played a little with them and by far, the best configuration I've been able to find...

That was a nice review btw oicdn.

The combinations I like are as follows:

LR: AD797
Buffers: Bypassed
DAC: LT6241HV

LR: OPA2111
Buffers: LMH6643
LR: LT6241HV

The AD8656 was also nice for the dac with impact but the LT6241 was more detailed. Its a hard call but the LT6241 better suited my setup.

The LM4562 as buffers had a harsh treble that I didn't like.
