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

... if i hear a bunch of stereo systems each having different preamps, i report what i hear.

Yes, but you are hearing and reporting on differences between systems.....NOT preamps.

MrT - Are you coming to conclusions on the differences of preamps based on each of them being heard in different systems? If so, how can you say one preamp is "warmer" than the other. For example, I can take the warmest preamp from the 80s, use it to drive a Mark Levinson (Madrigal) amp from the 90s and then into a pair of Thiel 2 or 3 series speakers. In such a system, there is no way anyone would ever know that there was a tube preamp in the system at all.....you'd swear you also had a Krell or Madrigal preamp from the same era.

you are right in one sense. in most cases, i am not comparing preamp a to preamp b in the same system.

my comments about a bunch of preamps auditioned in diefferent systems is that i find certain preamps lacking warmth--,i, a roll off in the range 1000 to 3000 hz, a slight peak in the range 90-200 hz and a laid back or recessed treble reponse, without regard to relative differences. if a preamp exhibits these characteristics in different systems, the chances are i won't report the sound of a stereo system as edgy or over detailed, especially if there is a tube amp, preamp and tube cd player in the system. i am using intuition nad the facts speak for themselves. i have auditioned some preamps in my own system and have compared several preamps in another system.

however, i would conjecture that i would not find any preamp designed today that is warm, based upon my definition.

A lot of interesting ideas and opinions being floated. Jafox makes a valid point about hearing various preamplifiers in various systems making if difficult to judge the preamp on its own, especially in reference to how it might sound in Mrtennis' system. Trying a component in one's own system/room is the only way to accurately gauge how it will sound in one's system. Cabling can/will make a significant difference in sound as well.

In my opinion, when looking for a current production preamp, and wanting a "classic" tube sound, one might be better served not considering what most people consider the "better/state of the art" models. Most producers seem to be designing towards a more neutral presentation, especially toward the top of their line/s.

I previously owned a VTL TL-2.5, which has a bit of the "classic" sound, while moving up the line to the 5.5 is less so. Both sound fantastic, but are slightly different flavors. The 2.5, tubed with Mullard or Amperex Bugle Boy tubes(Mullards my personal fave), leans heavily toward a "classic" sound...without being too much of a good thing.

Mrtennis,
My choice of preamp is the Supratek Cabernet 300b.It has the classic tube "gorgeousness".It is outside your budget however and the new Cabernets use different tubes I believe.Also the cheaper 300b tubes like the EH are not a patch on the mesh plates in this regard.
Mick Maloney from Supratek might be able to make you one especially though.The Supratek Sauvignon is a fantastic preamp but not as "tubey" sounding.It might be able to be tweaked though for a more tubey sound.
Also you should contact Supratek,describe the sound you are wanting and ask Mick if he can make you a preamp with this sound and to your budget.He is a busy man but his aim is to please and might be able to help out.No gaurantees but worth a try.

Mrtennis:
Might want to consider the Cary SLP-05 (6SN7s) or the more euphonic Joule Electra LA-150 Mk II (6350s). Also, have you tried VAC?
