Tube pre-amps $3500 under to add "warmth"


I'm interested in thoughts. Looking to add a touch of warmth to an all solid state digital based system. I am considering the following but have not heard any except VTL.

Modwright SWLP 9.0 SE
Dodd battery
Supratek Sauvignon
VTL 5.5
Audio Horizons TP 2.0

Anyone had the opportunity to compare some of these?

I am biased as an owner but the Melody SHW 1688 II sounds like it would also be worth auditioning. Very musical - great tone.
Thanks for the tip on the other pre-amps to consider. I'll start doing some research. Keep the thoughts coming.
I'll second the Joule LA-100 MkIII. Very musical and at used prices tough to beat. At new prices they are slighly over your budget.
