The Whest is cable sensitive... Change the interconnects and power cord and you'll have a completely different sound.
I have the PS.30RDT and it sounds quite a bit more dynamic and less laid back with the MAC HC power cord. Note that MAC also makes an "Ultimate Source" power cord, but the results I'm talking about will come from using the HC cord, which bested every other AC cord I tried with the Whest.
Then if you still miss tube sound, simply get a quality tube line stage.
