I don't have the Move but right now I am listening to the 650's as I tend to like them better with the D1 than the Equation RP21's, and the sound is big and powerful. The bass is well controlled but not overphowering, and this is while listening to Dire Straits, which has ample bass. I listen about 1 oclock for loud. Anything past his and it is too loud but no distortion. I turned it up to the 4 oclock , partially off my head, and the sound is still clean with no distortion. I have tried this with different opamp configurations and the D1 holds up with plenty of power.
They aren't cheap are they? I don't know the conversion to US dollars, I guess I should look it up. Yes that is the opamp. I am using the AD8397's in the buffers postions but I liked the AD8066 with the stock buffers as well. HiFlight likes the 2111 also and seems to prefer it a little to the 8066 as in the last bit of refinement.
Interesting: I am using the HD650, which I haven't been using too much lately because they are not closed and the person sitting across from me here at home doesn't want to hear the music. I don't blame her but I have listened off and on with them, when she is gone and today I let it run much of the day with them. The sound has changed over the last few hours and I wonder if it is the amp pushing a different load that may be making some positive changes as the sound has gotten a little more open and the bass is very solid. I go back to my Reference and Monica to compare to and not just my ears as they may or may not be adjusting to the sound. It is always good to have a reference point.

Thanks for your promising impressions. Dire Straits rock! 'On every street' was the second CD I ever bought (fifteen years ago) and I have liked them a lot since then ... and now I know that their first two albums are even better.

Looking at this photo, I'm having difficulty picturing how the two AD8397s on the adapters can both fit into those buffer sockets-- they seem extremely close together as it is and aren't the Brown Dogs rather larger than the NE5532s (as the AD823 is here)?
John or Ron, could either of you post a photo with the AD8397s in place?
Agreed. My reference point is the Move at the moment, and I have to say, without direct comparison, I would not have noticed some of the D1 'flaws' that easily. And I am mindful of the fact that a reference is the sound I like rather than some kind of objective point when it comes to good amps... This said, the Move is bloody brilliant...
Are those the right ones to get? Also where can I get the brown dog adapters if I end up with a D1? And I need two of the AD8066 one's right? Thanks a lot.

Yes it is tight, but they fit. Just about touching. I put a loop of thread around each one so I can lift them out.
You only need one AD8066, as they are dual-channel. The D1 uses dual channel buffers, which is different than many of the other portable amps. That limits the buffer selection slightly, but it is hard for me to imagine a better choice than the AD8397 from the standpoint of output power, and current drain. It is also very low noise with excellent square-wave response.
I am preferring the OPA2111 over the 8066 as I think the high end is rendered a bit more accurately. The drawback is that it is quite expensive and hard to find.

Thanks!
Yes could either of you do that please? Aren't there two places for buffers? Why would you only need one? Sorry I'm a noob at this. I see there are two NE5532's in place. Also aren't the OPA2111's there at Newark where I listed it?
You need two AD8397's. They go in place of the NE5532.
Find some headphones that are harder to drive and crank it up with the D1. this is not a listening level but above that to really make the amp work. I found out today this had some positive effects on the D1.
