Pass labs X250.5 vs Jeff Rowland Model 10, or 201

It took about 250 hours for the unit to mature. Base did improve and the depth of the sound stage grew larger. The general warmth and musicality stayed consistant after about the 100 hour point. By the way, I'm driving Avalon Ascents which are not easy speakers to drive in the base department. The 350.5, however, does a wonderful job of surprising audiophile friends who heard these speakers driven by various high powered tube gear. (VAC, BAT,
ARC ) Even some of my tubes or die friends have had a hard time finding fault with this power amp.

I own Studios as well and one thing for sure is that you need gobs of power to really make them work. I tried a bunch of stuff. For sure, the Rowland 201s cannot control the bass on the Studio. Am using a Rowland 302 now.

Carl,
Have you tried the 501? how the 302 sound with Revel Studio? and what cabling? thanks in advanced.

Have you looked at getting a s/h cj prem350 to match your cj pre?

The 302 has been great with the Studio. Compared to Krell monos: 500% more detail in the music, all the subtle nuances are now there, where the Krells sounded slightly more veiled and dark. More open sound with the Rowland by miles. Not as much bass slam, but does a fine job, there. I think the Krell's delivered more current in terms of being able to drive absolute levels of volume. I think the Rowland starts to strain just a tad at ear splitting levels. I did not try the 501s, but it would have been nice to compare.
