@rird... A suggestion: You can find many tube preamps for quite reasonable money on the Bay of E. Everything from kilobuck examples down to a couple hundred bones. You really can't go wrong with something from ARC. I would stay away from the cheap Chinese knock-offs as some of them while having tubes, do not have them in the signal path. IME, tube preamps are not black magic. Yes a bit of warm up time is helpful but SS sounds better warmed up too. And if you decide tubes aren't for you, you'll likely be able to recoup your investment.
Good luck and Happy Listening.
