Pls recommend a tupe pre under 2500 for my system.

Interesting comment Darlmoebius about ARC pre's that use the 6H30 tube. I've read numerous posts here and there that seem to make the point that the 6H30 tube makes ARC amps and pre's sound more analytical, almost "SS-like." At this point, the only piece of ARC gear in my rig that doesn't use the 6H30 in the audio circuit is my PH-7 phono pre. Can't honestly say that I've heard enough ARC gear to express a view one way or the other.

I own an LS-25 and agree that it doesn't have a trace of "tube warmth". That said, it doesn't have any SS "edge" either. This particular piece might be the most extreme ARC pre in that regard, but I still wouldn't call it SS sounding. Just "pretty neutral" and quite revealing. Later versions from ARC may have backed off a bit, but none that I've heard sound at all tube-like.

Therefore, I'd agree that these wouldn't be on my personal list of preamps appropriate to the OP's stated desire.

I was going to suggest the BAT 3iX, but the VK-31 mentioned earlier has a better user interface (the 3iX is very basic), while also allowing tube rolling. I don't know what the VK-31 users for power tubes (the 3iX uses two 6V6 tubes), but I was quite surprised that most of the improvements in warmth came from replacing these tubes.

Joule Electra LA-100 or LA-150 would probably do the trick, if they can be found for $2,500

If you are trying to get the tube sound I agree with Darkmoebius
You cannot go wrong with the Joule Electra Preamps. At the price they go for here, they are a steal.
