op
your compromised room notwithstanding, your wilson benesch speakers are quite resolving and you already have a tube pre feeding a solid state power amp, so you have a reasonable system tonal balance i would guess (although my experience with adcom amps is they do tend to sound quite typically solid state)
i would suggest you try a denafrips pontus, which is quite middle of the road tonally (not too sharp/lean or too overtly tubey), a better soekris r2r dac, or if you can spend a bit more, a doge 7, which has a tubed output stage, but is also very middle of road in tonal balance
all are excellent at their respective price points, and iirc they all can handle dsd
