You have a lot of good options here to choose from, but don't forget the benefit of a tube preamp is the ability to try different tubes! The warm, rich, detailed sound you're looking for could depend on the tubes you decide to use as much as the preamp itself.
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.
