I have the same PSUs (at 5.02 & 5.04 volts) powering a Katana + Isolator. it is now a toss-up between the Katana and a pretty costly DAC plus transport combo (RRP at some £2.5k+). there are 44.1 Tidal tracks that sound better than their equivalents off CDs (and vice versa). also played into Harbeths (& I'm also impressed by the low frequency clarity).
I tried an early version of the IQ Audio dac, that was easily bested by the Allo Boss, that in turn by the Katana. the PSUs (so I like to think) brought greater precision, clarity and weight to an already amazing degree of resolution.
