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.
