The Rotel RB1590 sounded warm with the 802D3, I had it in my room at the SAME time as 3 other amps (Cary 211fe, Classe CAM600 monoblocks, and Boulder).
It was not shamed by the rest of the gear other than the Boulder.
It sounded very acceptable and it was very good for the $2999 that it is.
The soundstage seemed cramped and narrow. There was less dynamics.
But I could live with it.
I a/b'd the Classe M600 against the MAC 601 at the store, I brought my amps there and plunked it on top of the 601... we listened to the 802D3. I came away liking the 601 more. It was warmer but still had the impact of the Classe M600.
The Boulder smokes them all.
Funny how the Classe M600 was used to tune the speakers, but clearly not the best with these other super amps in the picture.
Cary 211FE is a little weak with bass.... but there is an etherealness to the vocals that is just superb.
So though I sold my 211FE to my brother, I am looking to bring back some Cary tubes (805AE) monoblocks to my system just for vocalists.
