I first heard John Voss' (Dourmandy) phono stage at the LAAS in 2017. This was an early prototype of this minimalist MM only, 40dB gain, fixed 47K loading battery powered phono stage. From the very first notes I knew that this was something special -- resolving higher frequencies in a way I'd never heard before. Most unlike me I placed an order on the spot and finally, 14 months later, after a lot of continued development its now in my system.
The Voss is a two box phono where the small black box visible under my amp stand is a power supply for the batteries and a three way switch for off/on/charge. It gets 30-50 hours from a charge and can recharge in 3 hours or so.
Only when you make a change of this magnitude do you realize how colored a phono stage can be. The Ref2SE is a fine stage and very musical and exciting but when you compare this to the Voss you understand its giving you a false low/mid bass boost that adds energy and bounce to recordings but also overlays a layer of stodge on everything else.
One of the best instances I can cite of this is on a mono recording of multiple voices and instruments -- take anything by the Chordettes for example. Through the ARC these are fun and high energy recordings and very enjoyable but through the Voss you can distinguish every voice, follow the lead and each backup individually and listen into the stacked mono soundstage with crystal clarity.
The Voss also excels at relative scale, small things (like flutes and triangles, and vocalists) stay small even when big things (like bass pedals or bass drums) are resounding all around them. With two many components the latter modulates the former.
So it's an expensive, uncompromising and ascetic phono stage but having tried it there's no going back
