Krell ksa-300s vs Pass Labs x-350

I see the sherrif is in town.

For the record, Jim never said his friend compared Pass to Bose, he compared his decision to get Pass with his decision to get a Bose system. Read before you leap.

I replaced a Pass X-150 with Rowland 201 monoblocks and feel it was a dramatic improvement, but I understand how personal these decisions are.

I owned an X-150 for several years. The Pass amps are good, but perhaps not as good as their reputation.

Have you listened to any of the latest generation of digital amps, such as those from Spectron, Rowland, or Acoustic Reality? You might not prefer them, but worth checking out. Lots of benefits apart from sonics (size, weight, heat, power consumption), if those matter to you at all. These attributes don't matter so much to me, but they are definitely in the nice-to-have category.
