the bass of 1641 is very deep and tight, but it sounds really dry...trying to get used to it.

ISL28127 has the best bass, OPA1611 too in some circuits.
ADA4841 also has great bass.  A bit forward compared to others.

it's hard to know whether it's missing stuff or if that's the other opamps that add their own coloration...it doesn't sound thin, just really not hifi, more like hardcore flat. SS is great, though.

 

[Mad Max]

Flat?

 

[leeperry]

in the sense of "uncolored", like the hardcore monitoring gear(Yamaha NS10M / Sony MDR-CD900ST)...it doesn't entertain me, but it sounds very detailed...yet, not too boring.

 

[leeperry]

Ah well, I've polished the signal quality fed to OPA1641, and it's really a great sounding IC

 
I fully agree w/ the ppl on diyaudio who said that it lets you hear what's on the record...it's very impressive as PCM1793 LPF, feed it poorly and it'll shred yours eardrums....most of my other chips sound utterly colored in comparison. It'll let you hear any weak link in your rig loud and clear

 
Putting those in a mixing console must really be something!

What is "hardcore flat" for a us coming from non-english countries?
 
A flat frequency response, can it be more than flat?

 

[Mad Max]

It's concave bass!!!
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
I'm joking. 

 

[leeperry]

yeah, it really sound very little colored to my ears and does everything well...it's a keeper for sure.
 
I'll run a shoutout against ADA4627-1B next week or so

 

[leeperry]

humm, ADA4627-1B is business

 
but I really had to improve the signal fed to it, this thing will spit back a crappy signal right back to your face.

Hey guys. I would just like to know if I can ground both left and right channel opa with the same screw. 

 

[qusp]

sure, only reason not to would be if you are running dual mono

Thanks qusp, very much appreciated. I have 2x single OPA, one for each channel. Is that okay?

This chip really rocks! It doesn't sound as good as a killer discrete design(it clearly doesn't retrieve as much ambience and sound cues), but you get 75% of the goodness for a few bucks....the last percents will cost ya

Nice! Where can one purchase them? And also the adaptor looks nice. Where can that be obtained? Thanks
