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.

A few days ago I am testing a stage of professional power that I have had for many years, a Crown XLS202, in fact I rescued it from a local, it did not work and I fixed it.
It's a cheap 200W amp, it's not very good but when I put it on with the Cornwalls, everything opens up dynamically, the ends come out, everything becomes big and vibrant. Interestingly, the XP12 suits him well.
So I come to the conclusion that I need a more lively amp. The Cornwalls appreciate it.
Another vote for Atma-sphere. 

I would also think that the problem lies more with the speaker than the electronics. 

I owned a XA 30.8 for a short time and could never warm to the sound. Perhaps it was attempting to serve too many masters and was good but not excellent in any category.
You do not mention your source or if you have changed to good power cords and interconnects yet or a power conditioner dedicated line but you are talking about throwing a lot of money on gear my guess is you should concentrate on the setup of what you have you will probably learn how good the gear you already have is.
Maybe get ahold of Nelson and see if he can help you out. 
All of us can recommend all the equipment we like. Its your ears you must please.
