If you are interested in tubes, you may want to try a used 300B or 2A3 SET Amp with some efficient (94db or above) speakers. While the Bass might be a bit light for Rock, the presence will knock you out - especially in Jazz.
If you want to go with Push Pull tubes (slightly better bass but does not have the presence of SET), I would recommend you look at the AES, Rogue, Quicksilver or Decware Zen for moderately priced gear. You can get away with more moderate speaker efficiency (89db+).
I originally went from SS to Push Pull tubes and then migrated to SET. Be warned, if you go down the SET path for your 2nd system, it just might force you to "upgrade" your primary system!
