No, I am still feeling the love for my Rotel A11 Tribute. After some experimenting, I realise that the reason the ELAC DBR62 sounds rubbish on the Tribute is that the ELACs did not sound good at all volumes and had a sweet spot. The ELACs sounded flat and lifeless below a certain volume and by the time I get them up to a good volume, the amp is struggling to drive them and sounds harsh and poorly controlled. This was true with the Rotel and the NAD D3045. I found a work-a-round by using the ELACs in a nearfield setup in a small room. I didn't have to turn the volume up as high as in my larger room downstairs to get to the sweet zone. Suddenly the ELACs sounded very very good indeed, far better than the Concepts in terms of detail, imaging and naturalness. Took it all back downstairs, speakers 2m apart, 2m from the speakers, in a room 3 times the size, and the volume was now too low to enjoy at the level it was upstairs. In order to get back to good listening volume, I had to crank the volume again, and it's gone. Just harshness left. Turn it back down, and its flat, boring. Take it back upstairs, great again....but only as long as I keep the volume within a certain "window", not too low, not too loud. I guess that if you have a much nicer and more expensive amp, like Kapkirks £1500 Denon PMA1600ne, then it can probably deliver current sufficiently to make the ELAC sound good at any volume.
As good as they are, within the narrow window available using my two amps, I am not the kind of person who likes to be so restricted in terms of volume and location of my setup. The Rotel works wonderfully with all the other speakers I have tried, including Q Acoustics 3030i, Concept 20s and 40s, Monitor Audio Bronze 2, 5, 100, and 500s, and Silver 100s and 200s, Wharfedale 12.2 and 12.3, and the Dali Oberon 5. So, since I am totally happy with my Concept 40s, I decided to part with the ELACs and stick with the Q Acoustics.
The A11 Tribute is not the amp for everybody. I find it to be gentle, refined and polite, unlike the Denon PMA600ne I owned before which had grunt and muscle enough despite its low power rating, but was less refined. I like the delicate nature of the Rotel. I listen mostly to acoustic, choral and singer-songwriter type of music, mostly gentle, heartfelt, soft pieces. I'm not into rocking out or techno or anything like that, nor do I listen at loud volumes. The Rotels play the kind of music I like through the Concept 40s in a way that makes me happy enough that I hope they last forever and I never need to replace them. I have not had this with the other amps I have tried at a similar price point (Denon, Cambridge Audio, Marantz, Onkyo, NAD).
