This amp looks interesting, so how is it looking from the inside/what are u using? Need to get into opamps and their characteristics, any link u can provide?
In addition to the stock ibasso PB2 OPamps: I use these
1. Lme49990 OPamps
2. MUSES01 & MUSES02 OPamps
3. Topflight kit bespoked by Ron in view of the above choices. Ha5002 buffers x4 , plus 4x single Opamp class A adaptors and plus 2x dual Opamp class A adaptors. But he will bespoke to your requirements.
I find the MUSES01 and HA5002 buffers most enjoyable at the moment.
I already have two OPA627s, so I suspect I may be tempted to buy 2 more to try them out as well in due course
The fun with the Pb2 is that you can try differnt sound signatures with the different combinations of OPamps and Buffers.
