Unfortunately I have not heard those amps personally however from what I've read I would go with the AGD Tempo or the AGD III Duet.
Here is one source of information:
3 choices for power amp
I am ready to upgrade my power amp.
I am currently using the amp section of a Primaluna Dialogue Premium Integrated Amp, thru the HT input.
My preamp is Atma-Sphere MP 3.3 Mk III.
My speakers are Acoustic Zen Crescendo MkII.
I have narrowed down my choices to the following 3:
Benchmark AHB2, Atma-Sphere Class D, or AGD Tempo.
Has anybody compared any 2 or all 3 of these in their system?
I would appreciate your feedback. Thanks!!
Based on my experience, you are most likely to get the best sound quality by staying within brand. I haven't heard your three choices but have an extremely good, modern class D stereo amp. My Coda S5.5 stereo amp, for not that much more than the above, given a side by side comparison, would make anyone considering class D reconsider. I believe there are others in the following link that feel the same way. |
I've owned the Benchmark and currently own the Atma-Sphere Class D. I personally think they sound pretty different. I found the AHB2 to be extremely clean sounding, very solid bass, and highly resolving. It had a super black background and you could hear into the recording like crazy. I also found it to be a little lean sounding and 2 dimensional, not much front to back soundstage. I liked it but at the time had a Pass X250.8 and preferred the big Pass amp. The AtmaSphere has the super black background and solid bass, but sounds much more like the Pass to me. I don't think it is as resolving as the AHB2 but it has more the color/tone of the Pass with better side to side and front to back imaging compared to the Benchmark. To me, the AHB2 is a great tool to analyze a recording, where the Pass and AtmaSphere bring you closer to the music/soul of the recording. My preamp is the SimAudio 740P (used on all 3 amps). I would go with the AtmaSphere if you have the AtmaSphere preamp and am happy with the AtmaSphere sound signature. Cheers |
+1 @vinylvalet The Coda is very special! |
