I auditioned a number of amps on Mirage M-3s back in the mid-90s. To my ears, the Acurus A150 and, I believe, D100 integrated sounded a bit less refined than an Aragon 4004 and Bryston 4B-NRB. I ended up getting a pair of M1-si's and running them with Bryston electronics, but the Aragon 4004 was REALLY close to sounding as good for less money. Good luck!
