All else being equal.............................

If solid state is your preference, I second the darTZeel LHC-208 'danalog' Streaming dac with integrated amplifier. This line of electronics is the finest sounding solid state one can purchase and while they seem expensive, they are cheap when you consider the superior sound.

I recently heard the Hegel 300 and liked it, though maybe not enough to trade in my Modwright to get the Hegel. Also tried the Vanguard at home recently. Also very nice but much more sharply etched than either the Hegel or the Modwright. That extra detail is both a blessing and a curse depending on the source material.
FWIW the Hegel H200 is discontinued so that may be hard to find.

I have not heard the Krell, but I did have the Hegel H300 on loan to demo. It was quite nice sounding, but VERY bass heavy (I tried it on both my systems).

I think some other good suggestions have been made here. Vitus, Dart, Aesthetix, etc.

FWIW - I recently purchased the Musical Fidelity NuVista 800 and really enjoy it. Something you may wish to investigate.
