The nCore modules it uses are superb, as I’ve enjoyed them in the NAD M22 (v1 and v2 sound largely the same to me). Being myself a longtime user of Rogue gear, and also co-admin of the Facebook Rogue fan group, I thought to try DragonN’s. Chatting with a fellow in that group whom I trust (we have similar findings on ARC gear) - he had owned the DragoN stereo and M22, and told me to stick with the NAD. That said, I would really have to hear for myself to be sure.
Btw even the M22 v1 will hit 300 Watts no problem, beating its spec. I do find it needs to be paired to a tube preamp. A SS pre with this amp is no fun at all. That must be the rational for the tube stage in the DragoN. BUT I’m not a fan of 12AU7 (which Rogue unfortunately seems to pick by default now), and also hate the JJ’s they typically ship gear with.
