This is the 3rd op amp I've tried with my mini usb dac. It really is amazing just how much this op amp improves sound quality over the Muses 8920 D, which was the 2nd op amp I tried. I can't think that I've ever had a better value hi-fi upgrade.

Have been Op amp rolling for the last year and have also been using Discrete op amps as well. These are very good value and if your voltage falls between 12 and 18 v then these are a winner. Leave about 24 hours to run in then compare to any Dip IC...you will not be disappointed. These are also easy to fit into a lot of player/DAC's etc Very user friendly. Using also another great inexpensive op amp which is also a very good op amp but is harder to install due to its size limitations.I have ordered several more of these due to the great size performance ratio. Have used these in an Arcam 6 CD player which has improved its performance dramatically. Was a fraction thin in the upper frequencies when first started using it but this tamed up after 24 hours run in. Recommended. Further ...

Further note...after a couple of weeks of usage these seem to get better even more then the first couple of days. Dynamic and detailed with powerful sound-stage and imaging.

I like it!
I used this discrete device to replace a Burson V5i in a Little Dot 1+ headphone amplifier. This discrete op-amp is not a downgrade from the V5i, it may be just a tiny, tiny bit, "mellower", but is in no way grossly inferior. It allows the "texture" of music to come through quite well. As always, other implementations, other's ears, may interpret this op-amp differently but for me it is a keeper. I have no affiliation with the seller or manufacturer of this device, these are just my impressions after running in the op-amp for about 100 hours.I used this discrete device to replace a Burson V5i in a Little Dot 1+ headphone amplifier.

Opamp to add a plus for listening any music.
I was swapping two OPA2604ap chips to these, and the new sound is amazing. It's like listening to the recordings live. Of course, all ears and preferences are different but i recommend it.
