tube preamp with satisfying low end?


Hi:

Just spend the afternoon auditioning a couple of pre-amps. The VTL TL2.5 and the Adcom GFP-750 on Magnepan 1.6 speakers and a Bryston SB-3T Amp. Overall impression was that I love the VTL warmth and bloom on the mid range and high end. However, felt that it was definately lacking in the lower midrange and bass. Adcom had much better overall dynamic range and clarity, however it had that digital edge to it that can be a bit fatiquing. Am looking for a preamp that has the "glow" of the VTL in the mid and upper ranges but has better low end. Any suggestions? My budget is no more than $2000 - new or used.

Sibelius, I think this is an easy one - the BAT VK-5i. Plenty on the 'gon used for around $2k. Luscious midrange and delicate highs with great, I mean great bass. I personally decided to kick it another notch and went for the BAT VK-30 since my budget allowed for it, and I love it.
I would also give serious consideration to the Joule-Electra LA-100 MkIII (w/remote); the bass response of this unit is exceptional, and the midrange is even better. A preamp for lovers of music.
I experienced similar dissatisfaction with the VTL 2.5 & even the 5.5. However the Adcom (I've never heard one) is Stereophile class A isn't it? Was it warmed up thoroughly Sib? I mean powered on for at least a full day? If not that could explain the grain.
Regarding the BAT: I'm very curious to try one, but I do have one question? Does anyone know the "step-size" of the volume control's step-attenuator? If it is in 2dB steps then that's much too coarse. If only 1dB or even 0.5dB steps, then that would be worth my trying.
