[QUOTE="croak, post: 22886, member: 361"] From the few substitutions I have done, there is certainly a very marked difference between different op amps used in I/V, as to which is best, I can tell you OPA627 sounds better then 5534 so far. But it is a dear amp. 6171 does very well too but it had a drawback of being a little pushy sounding at times, some may find this less desirable then the 5534. I need to pul some OPA604 out of some other machines around the house. This affordable chip has the ability to just be lovely almost anywhere anytime with little nasties. It is in fact so popular BB have pulled it from the sample program... Now trying 627 i/v and AD844 sum. Wish I had had 4 not 3 844 as it is a good I/v op amp. Not listened yet, AD844 are new and are "warming up". PS: I think this thread, with subjective or objective refinements will be a great resource for gerdac owners and hence would like to keep it about Gerdac, not blind ABX testing in Sweden. [/QUOTE]
