Upgraded to Burr Brown opa134 series, both buffer and amp. Gain a bit brighter and more forward mid.

So how do you like the sound with them?

I like how it sound right now. Compared with the stock opamp, it push abit more detail and more lively but less warm. Music sound snappier and fast.

Yeah, those op amps used right are pretty nice.
