Best Tubed Preamp For A Warm, Rich Sound, Yet Still Detailed and Agile


As the title says, I am looking for an exceptional preamp (obviously tubed) with warmth and liquidity, some of that golden glow, in the midrange and highs. I do not want slowness, or lack of detail, however. My budget is up to $6,000.00, for a used model. 

Based on my research, many of those that might make the list are very rare to find, and other recommendations would be greatly appreciated.

I would suggest Shindo.(Aurieges or maybe a Monbrisson, perhaps a little over your price range, though) or a Lamm LL2 or 2.1.  An older VAC Renaissance might also be in your range, if you can find one.  I have heard all of these in my systems at various times and have enjoyed them all.
+ 1 on the  Lamm LL2 and Monbrison. If you're not doing phono, you would be wasting a very good phono stage with the latter. As much as I love the Shindo, the Lamm may match a wider range of amps.
Atma-Sphere MP-3, would be my recommendation. Even better if paired with Atma amps.
I never knew sound could be reproduced so cleanly and transparently.
