Going with my present experience with the A1400 vs my Denon 3808, the difference was quite noticeable and I feel the speakers really opened up with A1400. Will these lower priced amps have the same sound as the A1400 I can't answer as i have not heard one. I have yet to try the A1400 with my M22s to see if they also open up more, but I also no longer have my Denon to compare it to.
I can say that the Denon still sounded very good on it's own, but the A1400 was just that much better at bringing everything to life.
