Should I sell my accuphase for this schiit

The Schiit return policy is 15 days.

Regarding the comment "Well Schiit measures poorly," : 

I was pleasantly surprised by the Schiit Aegir's measured performance. It is a well-engineered amplifier at an affordable price.—John Atkinson

I recently spent several days "auditioning" a Schiit Aegir...it's a great sounding amp (I have very efficient speakers so one is enough), and although I had trouble with the first amp they sent me...it's "protection" kept shutting it off...the second amp works fine (great service at Schiit...they got the new one to me immediately). After a while I put the Aegir aside and my Dennis Had Inspire SE Firebottle HO (high output...supposedly 10 to 17 watts per channel depending on tubes) went back in the system. The Had amp sounds better in every way...the Aegir has a hard to describe "sheen" of Technology At Work or something that renders its sound seemingly artificial-ish...nice detail and tonally very nicely done...but the single ended Had tube amp just sounds better to my ears, which are the ones I use to listen to things. In any case, I still recommend the Aegir to the "efficient speaker" crowd although I'm shipping it back to Schiit. An interesting experiment but my brain must simply be accustomed to tubes and their inherent harmonic palette and musical rightness that clearly fits my tastes...oh well. Note they charge a re-stocking fee AND return shipping's on you...but to satisfy my curiosity it was worth it.
