EtherRegen saved my Devialet experience

[Snoopy8]

I heard that further tuning can be done with a linear power supply like Farad Super 3 or going optical.

The biggest improvement is the EtherRegen itself. From there, there are incremental gains, e.g. linear power supply n(LPSU), better Ethernet cable, using optical link, getting a 2nd ER, adding a clock etc...   There is a rabbit warren to explore, and often any gain is system dependent. However many people get the ER, maybe add the LPSU and stop there.
