I'll rate them in the order that I found that each performed.
1. Theta Gen V (Try to get the Va version with Balanced outputs - aka fully balanced)
2. EAD DSP7000 Ser III (mods available or for a little more get a EAD Ovation or EAD Signature and use that as a preamp also, this saves you an interconnect and the EAD Signature is an insanely transparent and musical unit)
Don't bother with the Parasound 2000 Ultra as it's not in the same league as the ones above.
Don't even bother with the PS Audio Ultralink (there are so many better units now for less)
If you are a Bass head the Theta will be more immediate, the EAD will be more tubelike warmth.
