@anotherbob
not sure what specifically your question ’which is better?’ is referring to...
but when i had the m33, iirc, the chain was
wtl amadeus --> dyna xx2 --> ayre p5xe --> INTEGRATED A v B v C ---> three speakers
1. proac d30rs
2. spatial m3 sapphire
3. harbeth shl5+ (briefly)
compared m33 (no dirac, straight int amp mode) against hegel h390, devialet (with sam on the harbeths), primare i30, sony ta 1es
also used digital streaming front end - blue node 2i dig out to denafrips pontus or audio mirror tubador
