What 8-DIP opamp (single channel) has the most bass impact in your opinion? Thus far, I've tried the OPA134A, OPA627AP, LME49710NA, and the AD8610. I would have to say the AD8610 seems to have the most bass impact of those listed. I also like it's lively sound. So I'm wondering if there's anything out there that you guys can recommend?

What is this being used in? You could start with the AD843. I might be able to think of something else to try depending on what your application is.

Sorry, I should have mentioned that in my post -- it's being used in an XM5 portable amp (by Practical Devices). It also has two BUF634P chips in it.

I'm considering trying the NE5534. I hear a lot of mixed reviews about it. Which one is the best of the NE5534's out there for my purpose? The SA5534AN or SE5534AN by ONSemi? Is there a major difference with the ANG version versus the AN version?

Even though I can't seem to get it behaving properly in my PPAv2 the AD843 used in every other application has been my favourite single opamp for bass attack, whack and impact.

Probably his XM5.. what cans, though?

Paragon: Yup, I said this in the third post -- XM5. I'll be using either the Denon D2000 or the Denon C700 'phones.

Thanks.

I agree about the AD843, it is the "Rock chip" in my little amp. OPA637 is a great chip but the sound is way too soft.....

Thanks for the advice everyone.
