Anyone running a tube preamp with a Pass XA25?

If you require a tube preamp, I recommend an Atmasphere MP-1 or MP-3, depending upon your budget.
The former gives my Ayre KX-R a run for the money.
@OP, 
If you could accept a SS preamp, then the Ayre KX-R would be my choice.

Good question. The ET5 and ET7S2 are cut from the same cloth but the ET7S2 has little bit more of everything that the ET5 has. A little smoother, dynamic, and cleaner. So, the sound opens up and just seems more natural. It is more engaging. It takes time to hear the different but it is there. I will keep the ET7S2. We can talk off line if you want to dig in deeper.

My system or maybe my collection: speakers - Penaudio Serenade Signatures, Penaudio Cenya Signatures, Penaudio Sara S, Penaudio Charisma/Chara. Amps: CJ Classic 120SE, CJ CAV 45S2, Herron Audio M1As, Resolution Audio M100s, Pass XA25, Wadia 151. Preamp: CJ ET7S2. Source: Resolution Audio Cantata Music Center 3.0, Innuos ZenMk III. Cables: Black Cat Setsuna ICs and Black Cat Lupo III speaker wires.  Graitech power cords. Blue Circle power line conditioner. 

To avoid more of the "threadjack" we can also talk about the trial and error off line. I gave up vinyl may years ago when we had small kids. I do miss vinyl.

@cellorover

thank you for your reply, helpful!

good to see the list of components in your system too! i somehow get the distinct impression you like penaudio speakers and cj tube gear !!!  😆😆😆

... and now back to geof’s regular scheduled programming...

@geof3 How do you like the Rogue RP5 and Pass XA25 combo vs your Pass XP12 combo? Does the tube preamp improve on the Pass preamp in yoir system?
Asking cause I had the Rogue RP5 running into the Pass XA25 and I felt that my system sounded too lean; the midbass punch was missing. I swapped the Rogue RP5 for a Cary SLP98 and then the Cary SLP05 and both the Cary preamps added the missing warmth and midbass punch.

@knik, the Rogue is actually very full in my system. Compared to the XP12? The 12 was very focused, pinpoint really. Not in a bad way. Overall sound stage was great, but center focus was tight. The Rogue is focused as well, but in a different way, not as pinpoint. Wider soundstage, and seemingly deeper as well. Low mids are rounded, and full to me. Again, less punchy. However, overall “slam” is very good. Keep in mind, this is the only tube preamp I’ve tried with the XA25, but for now, it’s a keeper. I need to stop with the crazy for a bit!
