pontus (all denafrips) have fixed outputs, i believe all holo dacs are fixed analog out as well (i am sure i will be corrected if i am wrong on this)
under 2 grand, i would consider
ayre codex (volume knob, but no remote)
soekris 1541 or 2541 (uses apple remote to control volume), excellent sounding unit
stay away from chi fi dacs with volume controls, they are poorly implemented and will strip bits at low volume, making the music sound more mechanical (true also for musetec) - same for rme adi2 (this unit has many many useful features but a quality volume control is not one of them)
