Onkyo A-50 vs Buckeye Purifi 1ET6525SA

@chanur I don’t think you would regret getting into the Onkyo Icon series. I would go with the M80 power amp either combined with the WiimUltra as a preamp, or with the amazing P80 preamp. The M80’s specs equal the Buckeye’s and the Icon series has some innovative technology that promises to be something really special. Plus, I think your wife would love it and you more for it, as @skeptikal notes. 
CheapAudioMan reviewed the M80, Tom Fine in April’s Stereophile reviewed the A50. 

Asked her for her thoughts on the M80. She loved it as well. Out of like 20 amps only the Onkyo ones she has actually liked. Something about the design speaks to her I guess. I'd have probably preferred a Schiit Wotan or Buckeye for all the extra power. How ever the Onkyo are nice looking so it's not the worst thing in the world. Probably will push for the M80 and get the P80 later. It will give me reason to complete the set.

I will check it out. I think I want something a little bit warm/vintage sounding since my speakers are pretty neutral . 

The Absolute Sound video review starting at 7:00 and 8:00. It’s a more systematic sound profile review. Note that the soundstage might be narrow.

Note that the soundstage might be narrow.

But it is tall, right?

Helping old recordings sounds promising to me. How ever I don't have a ton of experience with sound stages and things as I have always used budget AVRs for Audio in the past. I think I'm going with the M-80.
