I have to attest to the Eversolo A6, i do run it through a DAC and it seems to punch above it’s class,
Yes I run it as a stand alone streamer and I have been impressed.
I run through a modest system, processing through both an ARC DAC 2 and McIntosh C2700 with dac2.
Not sure the rest of the system matters, but those that need to know;
Krell KSA
AGD AUDION MkIII Mono blocks
B&W 805 d4
B&W Matrix 802S3
