I’m convinced the Mutec Ref10 adds value to the EtherRegen, in particular when coupled straight with BridgeII using good RJ/E. This audiophilestyle topic offers nice insight about extern clocks with the ER.
I took the Matrix route. Although my (modified) MelcoN1ZS10 offers sophisticated RJ/e output it immediately became clear that the BridgeII was surpassed going AQ Diamond usb>Matrix>AQ Diamond i2S>DS, so i dismantled the Bridge.
Adding an UpTone UltraCap 1.2 to the Matrix was another nice jump up.
Thereafter came the EtherRegen, with my AQ Diamond RJ/E into the Melco SQ-wise a nice step up streaming Qobuz and Tidal.
Most recently I purchased a 6V Farad Super3 with SR Orange fuse, Furutech Rhodium AC inlet and upgraded DC cable level 2 silver. Connected the Farad (powered by P10 with Siltech SPO-18m) to the Matrix and OMG, wasn’t prepared for this one. Quite unbelievable what a really good LPS can do to the Matrix, this is a revelation!!
Finally connected the Uptone to the EtherRegen which ultimately yielded another small improvement streaming Qobuz & Tidal.
