Of course! Isn't that what this hobby is all about? How else would you tweak the sound?!

Any suggestions on what to switch to? If I like how it sound / functions I might commission a regulated ps.

Well, most likely, you are going to try the most expensive option at some point, the Burr-Brown OPA637 (you will need a single-to-dual adapter and 2 chips).

Here are some good reviews of different op amps to get you started:
Audio Reviews: Flavors of Audio Op-Amps
Notes on Audio Op-Amps

You could also try audio-gd's HDAMs (also expensive). н¨ÍøÒ³ 1
"Earth" is the best one. Check your space limitations and get the extension leads if necessary.

Would I need to replace all the ones in the unit?>
post #23 of 39
You'd need to replace the opamps in one section, eg, the headamp part.

Alright. Where should I be looking for a power supply?
post #25 of 39
There might not be anything wrong with the one that comes with the Dr.Dac2.
Usually regulated > unregulated, linear > switching, and noise-filtered > not noise-filtered. But the amp/dac itself probably has its own noise filters and voltage regulators if the stock power supply does not.

What opamps are you using
post #28 of 39
ok the amp isn't mine - it's the property of my mate but the boy had forgotten that it's at my spot hehe

opamps? hmmmm lets see......

1.opa2604ap -54actk7
2.opa2604ap -54actk7
3.opa2604ap -77w4n9b
4.ad8599 - a#748

im new abpout that kind of stuff but the marks are as above

i haven't heard different configuration but this one is my personal hero - it blew me away. i have westone 3 and akg k701 but hd600 is the best for me here. it is soft gentle sounding for me with HUUUUUGE soundstage....i can hear it perfectly when it comes to series like Californication or Dexter - reasonably new serials which sound BIG on my gear. as for the w3.....i couldn't believe that they can be more punchy but aye...they are . The source is DYIMod made by Qusp, plugged into line in via Qusps LOD + female mini jack to rca connects. that is all i can write ATM about it because i am still testing it. i'm sure that i'll have dr.dac2 for me too, when the time will come to give it back to my mate.

cheers
