@arafiq Thanks for a nice thread. Enjoying it!
For now, I’m thinking of trying a tube preamp with my SS amp.
I really enjoy going back and forth from non-tube to tube preamp with my Pass XA-25. At first I enjoyed a preamp with an 12AT7 tube input (2 tubes). But once I tried a 6SN7 tube, I sold my first preamp without any regrets. If there's a good match between preamp and amp, you may hear what I did: a really inviting, smooth, more spacious soundstage and a midrange that really draws you in. Seductive is the word. Of course, there are many differences between systems, but those who love the 6SN7 used these types of descriptions and I found them apropos even in my room, with my speakers, etc.
