I have not listened to any of the Jay Audio transports however I did listen to PS Audios senior dac and Direct Stream Memory player combo in two completely different systems with other competitively priced digital front ends .
The PS Audio combination new in 2017 came in 3rd place behind a Esoteric KOx1 SACD player and CEC TLN 2 transport with Denafrips Terminator dac.
The comparisons were done over a few weeks in the fall of 2017 switching the PS Audio dac senior for the Denafrips and the CEC transport with the PS Audio dac. The Denafrips with the Direct Stream memory player was immediately liked seconds into the first cut. The CEC combined with the PS dac senior wasn’t so obvious at first listen however what stood out right away was in the sound stage with better layering .
The CEC transport was preferred over the PS Direct Stream player and the Denafrips Terminator was preferred over the PS Audio senior dac.
Using exceptional recordings like Tonian Labs Drums & Bells sounding even more realistic presence with the Esoteric player and CEC Denafrips combination.
Hearing the recording Drums & Bells for the first time that bass drum on the first track scared ever living crap out of me .
Speakers used were Magnapan 20.7 with Rel subs and the Focal Utopia.
Finally , chatting with an owner of the Jay Audio transport last year I have high confidence in what he says about it .
