Pass X150 or CJ MF 2500,,,

Ray, I was wondering a few things. What's the sensitivity of your speakers? Are they hard to drive? What's the input impedance of your preamp? What are you looking for in your next amp? What kind of music do you listen to? There have been a few used units for sale on Audiogon in the last few weeks, I'd reccomend the "A" version. I had mine upgraded to the "A" version two years ago. After the upgrade, the amp had better highs, better bass, more control of my speakers, and a clearer sound. The soundstage expanded, while musicality remained close to the same presentation.

Ray, I just thought that I'd also add that the bass on the CJ2500A is a slightly loose bass. The unit itself will give you a "full" sound. Instruments like synthesizer, harmonica, and acoustic guitar sound three demensional, with a good front to back layering. With the CJ you get a more tube-like bass, but it can be quite powerful. With some music, I've heard the wood blinds over the windows on the side walls shudder and shake. Hope this helps. Good listening!
