I'm curious about all this as well. More specifically, how big of a jump in sound quality is there between the M2 and Rag? For now I don't really care about running speakers, I'm really just headphones only. I'll also be running balanced out to my electrostatic amp, so pre amp sound quality is important. I wouldn't even consider the Rag except I'm back to considering the Yggy as my next DAC. So theres that whole "making everything match" issue. But if the M2 is almost as good as the Rag, I could live with the cosmetic oddities.
Maybe reddog, can chime in on this?
The MJ2 is a very nice, somewhat detailed, natural sounding amp. But the Ragnarock just out performances it, especially using a XLR headphone cable. The Rag has so much power and control, the overall sound it tube like, the bass has such impact, yet it is textured and controlled, never ever mudding up the mids. The mids are lush yet ever textured and revealing, yet being ever musical. Likewise the highs are spot on perfect and revealing to the artist. The overall sound is extremely detailed and natural sounding yet always so musical.
The MJ2 is nice but its not as revealing and transparent as the Rag, nor is it as musical sounding. I had been using the GMB and MJ2 almost exclusively for over three week and enjoyed the sound. The one day I went back to the Yggy/ Rag and was just awe struck at how much better it sounded. The synergy of the Yggy/ Rag. Is like audio herein and I just want to listen to the music and ignore all else. Who cares if the phone is ringing, who cares the cat once out of the room, or if the smoke alarm is chirping, just listen to the music, till you become a dancing fool.
