Audio-gd discrete op-amps reviewed: OPA-Earth, OPA-Moon, OPA-Sun v.2 - Page 26

I got the adapter on ebay: http://www.ebay.com/sch/sorch_audio/m.html?_trkparms=65%253A12%257C66%253A2%257C39%253A6%257C72%253A5698&rt=nc&_dmd=2&_trksid=p3911.c0.m14&_vc=1&_sop=15&_sc=1

I've tried a few of his adapters, they're all 2oz, they have a very thick PCB and pins that provide an excellent contact within DIP8 sockets and all around they sound far better than those 1oz and very thin browndogs to my ears. This guy knows how to design adapters

About the AD797BNZ, I got them off a chinese broker....these are hard to source, and I believe he ran out but I could ask him if you needed a few.

Thanks leeperry for all the info. If you could that would be great as I trust you they are good but if you can't that is fine too and I will seek elsewhere.

Hah, he makes them w/ white PCB now, they look so deliciiiious

Another great chip is OPA1641, it doesn't try to impress you like 797B...it just sounds very musical and detailed, and those thick 2oz thai adapters manage to extract the best out of it:

The pins are so thick that I'm always afraid to break my DAC board, talk about good contact! The SQ improvement over 1oz browndogs is dead obvious, they sound shrill and bright in comparison..I even had to reduce my ears resonances EQ

I'm kind of noob when it comes to opas so I need some advices. I ordered  this Dual Opamp Adaptor little too hastily without knowing what kind of AD797BRZ I should order for it. So I found this single AD797BRZ from ebay and I would need to buy 2 of those for the adaptor, right? Then there is this dual AD797BRZ that do not need any adapter? So should I get 2 single opas for the adapter  and are there any differences with those two AD797BRZs? Lastly I do not have any extra power source for my Audio-gd FUN and I read somewhere that opas get better with extra power, so can I drive dual AD797BRZ without the extra power source?
