Can anyone compare the Leckerton UHA-6S MKII to:
1. iBasso Warbler P4 ?
2. JDSLabs C421 AD8620, or any other opamp.
I own the iBasso P4, but am suffering from Gear Acquisition Syndrome and want to understand the differences among these three portable amps.
I had the P4. Tried many different opamps (including HiFlight's kit). The UHA 6S MKII is just way better.
