I agree, opamps don't make much difference in msot cases  but the default opamps on the d1 give you highs that pierce your ears more than the 4562.  Besides that no change in sound signature.

It has certainly surprised me how close in sound quality the D2 and NFB-12 are, being that the NFB-12 has discrete circuits. It could just be my usage (more games and HD video than FLAC music) or my setup (middle of the road vintage setup) but that's really how I feel. IMO, the features between the two make more of a difference. BNC input, front panel power button, tube output on the D2 and headphone amp on the NFB-12. It's really hard to choose. I really think that in order to hear differences or have the D2 be the limiting piece in your setup, you must have over $800-$1k of equipment after the D2.

Depends on what kind of signature you want, the NFB-12 is undoubtedly on the warmer side of reaching neutrality.

A quick note to those interested in some impressions about the D2, I have added a post to the existing D2-specific thread:

I rolled in a lm4562 to the headphone side. Didn't like it at all:mad: Harsh highs, lack of detail seemed that everything was compressed. Put the original back in and all is well.

So far I haven't seen anyone have this issue but sorry if this is a repost

 

On my D1 I'm getting alot of noise that's being output through the SS line-out and tube pre-amped line out. However, it only happens when I'm feeding a 24/96 signal through optical.

 

Has anyone else had this issue? It's a real bummer because its super noticeable, especially with 24/96 vinyl rips since I have to up the volume on my amplifier.

Today I replaced both stock opamps with LT1364CN8. Noticeable upgrade! Sounds much clearer and has a punchier bass that makes me love my DT770Pros again, as opposed to preferring brighter headphones with the D1.

 

FunyunBreath, I had similar problems with 24/96 + stock opamps that now seem to be gone. I'd get noise at even moderate sound levels with 96k, but now I can crank it to 100% and hear only a faint white noise that seems normal. Might be worth trying as they're not very expensive opamps, and it's an easy mod.

You replaced both opamps with the LT1364?

 

I have the LT1364 and LM4562 in mine
