I'm sure it's good, while my old discrete Yamaha X2 pre is a good mariage with my amp (but to be true I have the Muse digital volume chip in the toolbox to finish) ... I 'd like from too much years now, try a tube I/V... But the layout complexity with ground and air cables for tubes is almost a no go. Well and the whole is expensive with the power supplies for a pair of tubes ! the opa861 are 5V, few parts around and works wonderfully for that I/V purpose.

yes, Vunce made one and you have the gerber on the thread if i remember. But take care of local decoupling as such oaps should not be on adaptators...
at the end it is also about what you have after till the speakers, opa1656 opa1612 (both double oap, adaptator exists too or opa1611 simple channel) worths a try too imho.

Vunce, I did a short comparison between the Easy DAC and the dedicated DAC (low drop PSU, jlsounds USB board, Burson V6c opamp and Allo USB bridge as a transport) - both via ACP+ head amp. It is really easy to prefer the dedicated DAC. More air, more reverberation, more natural, less noise (the noise one just become aware of after it has gone). Sorry to say that the dedicated DAC is just so good.
Cheers
Hi Ernest,
If your going to try a dedicated I/V output stage, I would highly recommend Pedja Rogic’s OPA861 circuit. The layout I had made loosely follows Pedja’s circuit, is not really an adapter board, it’s a full layout with onboard +/-5v LDO psu and all the required local decoupling. All SMD though
Hehe!!Check it out in Miro’s main DAC thread.
