What's a good alternative to Pass Labs?


Owner of the x250.5 (pass labs). It's a remarkable amplifier, it just doesn't seem to synergize all that well with my speaker. Something a little less bright (a little more forgiving) and something slightly less warm. It seems to get warmest in the mid-bass (bloat), and brightest of course in the higher treble. The mid-bass warmth/bloat exists at lower as well as higher volumes, the brightness starts to get bad at louder volumes. I think they that Pass is a warm neutral, so perhaps i'm just looking for something that's just neutral. Any advice is greatly appreciated!!

budget less than $10k. used or new ok.

Besides the question of what speakers are you using which is necessary in order to make suggestions I'd also want to know what preamp, interconnects and speaker cable you use? All of those can have an effect on what you hear.
Colonel:
First a response to Lak will help put you and responders on the right track. Then, consider a CODA amp, made in Sacramento, CA. I could not be happier with my 15.0 amp. Coming with gobs of Class A sweetness, it may be just what you seek. Alternatively, the higher-power but less Class A model 33.0 may also fit your bill. Top quality, super solid engineering, and great folks to work with. Good luck.
Hey guys, I apologize, I should have my system info in my original post.
