“Why don’t you guys offer OpAmp (operational Amplifier) upgrade?” That’s probably one of the most popular requests from our customers. So after a lot testing and comparing, we finally chose BurrBrown OPA627 single OpAmp as our OpAmp upgrade offer.
OPA627 is an incredible OpAmp and it will give you a huge boost in the clarity and detail of the music. You will notice the difference as soon as it is placed in your unit.
OPA627 is a single OpAmp, that means we need to solder two OPA627’s on a small PCB board in order to put it into the dual OpAmp socket of the D1 and D2. D1 uses two dual OpAmp’s ( 4 OPA 627’s) and D2 uses three dual OpAmp’s ( that’s 6 OPA 627’s). All the OpA 627’s in one unit will be carefully matched to ensure the maximum balance and sound performance.
I would recommend this upgrade to anyone in a heartbeat.
