I have a few 4032 and a few 4031's, I should be ordering up some adapters here soon.
There are many SOIC that I want to turn to DIP8 for testing in this card.

I may have missed it now but is there a setup yet of the I/V's (exclude buffer spot for now for those of us who use HP out) that tames the harshness of the highs and thus also brings the mids forward a bit?

Are you using the EQ at all?

YOu can try the OPA2227's they have a good bas range and a glossy high range very similar to the 2134's.

Have you tried the 2134 in the I/V?

LME49720.

Ah but the LME49720 compromises bass output and decreases the 'punch' as you described.. I'd rather not loose that.

I have not tried 2134's yet. Because the way my computer is built (watercooled), its a real pain in the ass to get the STX out from all the tubing going around it. So I'm looking for a combo that I can do once, and hopefully never touch again (until I have time/funds to redo my water loop)

So what I'm looking for is the bass to stay the same (or get better) but the highs to just be tamed a little bit which I think on its own will bring the mids up a little bit but if the opamps do that themselves, then bonus

Edit: not using any EQ.

@Boj, I got a set of extension wires, you can get them from Audio-GD or Burson and they allow you to do testing with opamps without removing your card. When you find the set of opamps you really like then pull the card and add the opamps.

I asked about the EQ as maybe you could fine tune the signature with the EQ to get a more precise reponse that your looking for.

I think you should still try it. The bass punch is decreased but I think it's still adequate. The soundstage increase and improved frequency response linearity may be worth the bass punch trade-off for you.

I would check out the 2134's they add a bit more weight to the bass and mids.
That is what I wrote down when I tested them, now looking back at my notes.

robscix how would 2x LMA4562 in the I/V sound when using them with the OPA627au's if you know.

not that i gonna buy them I just wondering. Tho I am thinking about changing the OPA's to maybe 637BPs, But i not sure.

What would be some you recommand other then BP's for the buffer,that still opens the sound up. but balance sound unless I just basicy said the opa637's?

Some have tried the OPA627's and found they were not a good match with the 2114D's.

You can try the LM4562 NA in the I/V. They may work out better for you then the others.

After some more listening, I think I prefer the OPA827 to AD825. In comparison to the somewhat lively presence of the AD825, the OPA827 seems to have a flatter/cleaner sound with a smoother, more present midrange. On first listen I was taken by the lively, open sound of the AD825; however, after a while I came to appreciate the musical midrange response of the OPA827. From what I can tell, the OPA211 sounds a bit better (more natural) than the LM4562/LME49720. And, oddly, I also noticed that the LME49720 sounds a bit clearer than the LM4562!

Are you talking about the OPA825 in the buffer spot with the stock 2114 in the I/V section?

Sorry... no.... different application. Still, IMO, the OPA827 is worth an audition if you're looking for something clean/neutral with a nice midrange, probably best in the buffer role instead of I/V in STX. Just a bit of an op amp junkie....

I have been hearing good things about the OPA827's though and I have a few of them. Just need some adapters.

I want to try those out on the card.
