Disappointment with Pass Labs - I'm looking for something else


Hello, I am new to this forum and my mother tongue is not English, so please forgive me if I make mistakes as I use a translator.

I recently bought an XA30.8 and an XP12. I was very happy but as time went by I began to not feel comfortable with the sound.
After doing many tests, I find that the XA30.8 sounds very very sweet but actually too much. I find it to be a loosely defined amp, somewhat muddy and lacks a lot of air and grip. The soundstage is very closed.

The XP-12 is the worst of the two. It is a previous that removes a lot of resolution and information, without transient attacks and sunken mid frequencies. Instead it brings warmth.

Has anyone of you found the same?

If you ask me, I have a Klipsch Cornwall and a dCS BArtok.

Now I want a capable amp, forceful, something warm, decisive, airy and with a great soundstage.

At first I thought of changing my XA30.8 for X250.8, and changing the XP-12 for a second-hand Audio Research Ref5. I am afraid of this change and continue with Pass, since I can go back to the same thing a bit.

On the other hand I have thought of going for a Luxman 900 combo, since it has very good reviews and from what I have read it could be the winning ticket.

Yes. in fact it is how I currently have it. more resolution, more dynamic, more clarity but less warmth and depth
I'd get rid of the Klipsch speakers before I'd get rid of the Pass gear.  And I like and own Klipsch speakers.
Correcto. Creo que es el paso más sensato. aun así, la serie xa tiene serios problemas de fuerza y ​​definición.

I'm with @unsound.  This conversation is not worthwhile if you're changing speakers.  System synergy is the critical factor.  I've heard gear sound terrible on one system and spectacular on another.  

Once you buy new speakers, start a new thread and ask for recommendations.  Then send that list to the speaker manufacturer and ask if they've got any favorites from the list, or any others you should really audition.  I don't think enough people use their manufacturers' knowledge to maximize their outcomes.
