Pass Labs INT 250. LOVE it! Best sounding amp for my application out of 7 different high end amps that I auditioned. The other amps were, Simaudio 340i, Naim Supernait 3, Pass Labs INT 60, Diablo 300, Luxman 509X, VAC 170i (integrated tube amp), and Hegel 590. They ALL sounded stellar. I’d have been thrilled with any of the ones I tried. But, for me, the INT 250 had everything I wanted and nothing I didn’t. Beautiful sounding amp. Sublime with my Harbeth Super HL 5+ 40th Anniversary speakers and dual power MSB Discrete DAC.
