I'm not familiar with your amps, but I'm quite familiar with the Vandsersteen 3a's. They need more power period! Vandersteen audio suggests between 100-200 watts for this speaker. I have ran them with 60 watt tube amplifiers, but have found the bass to be a bit lacking. I have also owned a McCormack DNA-1 while it did drive the 3a's quite nicely, I didn't consider it liquid and tube sounding. But then how could it be? It is not a tube amp.
The Krell pre is a mismatch for a tube amp, I would think your ears got to be bleeding because of the harshness on the highs. It is not a good idea to have a solid state pre combined with a tube amp. If you insist on using solid state then you might try using a tube pre and a solid state amp. Personally I think everyone should run a tube pre and a tube amp.
