krell FPB300 or jeff rowland model 7

See I disagree with Elberoth2. I didn't care much for the Pass X250 in my system and like the Krell better. The Pass was too resolving and fatiquing for my taste. The .5 series is warmer from my understanding.

Please explain "too resolving".

I don't believe in an excess of resolution.

However, system incompatibilites are far more likely the issue.

The Pass is too resolute for my system. The BAT sound matches my speakers much better and my speakers (Tyler Acoustics) are not bright at all. I consider them fairly neutral.

I understand excess of resolution but it can be fatiguing in some systems. I feel the Pass X250 would match warmer or darker sounding speakers.

One more time.

There is no such thing as excessive resolution.

You have either system or personal preference issues.

If you had build your system around BAT, which has rather distinctive sound in my expirience - dark with limited microdynamics and resolution (I have owned 51SE and have auditioned VK200 and VK-500), and you are happy with it, then it is no suprising, that you find Pass to resolving and too bright.
