Moscode 401HR vs Pass Labs X150.5

So...for those that followed my previous thread, I am still in the hunt for the best amp under $2500 (after auditioning and returning a set of mono amps). I really have not been able to find much on the differences between these two amps sonically. I know the Pass has better resale value, but that's not my primary concern, although it is a concern for sure. The Moscode is rated at 200w into 8ohms (300 into 4ohms), the Pass at 150w (also 300w into 4 ohms I believe). I also know that Moscode improved upon the 401HR with the 402AU. Anyway, my tastes are bluesy rock, female vocalists and jazz. My system is as follows

AIFF lossless => Peachtree Nova USB DAC/Preamp => ??AMP?? => Dynaudio Contour S3.4 spkrs (4ohm load, 88db)

If anybody out there can offer comments as to how these two amps compare (or don't!) I would appreciate it. Thanks

Also, much has been made about fluctuations in the quality of electrical power from day-to-day and even hour-to-hour. Perhaps the ARC is more sensitive to this than other designs? Maybe auditioning something like the PS Audio Power Plant is in order. Just an idea.

Bondmap, that's a great suggestion! I was considering something like that. But now I will pursue it more earnestly!

Tvad's idea is solid, but if you are mortified of electricity like me, most power products, including the PS Audio, are available either direct or from resellers that will offer a generous return option. If the device doesn't fix your issues, just return it. You could be out shipping charges, though.
