Spectral amp choice+ Eidolon

I found the DMA-180 S2 to sound much better than the pair of bridged DMA-90. The DMA-180 S2 was sweeter in the upper midrange and highs, had a lower noise floor, and had deeper and tighter bass control.

I was using the Avalon Arcus at the time. I would guess that there would be a larger gain in performance using the Eidolons.

Good Luck.

Hi, I have a pair of Avalon Eidolons in a Spectral, MIT system. I have been using a Spectral DMA-250 amp, 30SS preamp, with MIT Oracle V1.1 cables, etc. Prior to the 250 amp I used a pair of 360 S1, 150 S2 with the Eidolons. Before the Eidolons I had a 180 S1, 200 and 100 class A.
The 180 series has a fuller presentation, ( deep bass, dynamics, etc ) then the other Spectral stereo amps listed above. The newer stereo amps, 150 S2, 160S, 200S, 250 and the latest 260, are more refined less colored, higher resolution, lower noise, etc. The new 260 is the best choice for a Spectral stereo amp based upon the improvements in the 360 S2. The 260 should have the bass weight of the 180 series if not more and the benifits of the newer designs. I have been told the 180 series is sensitive to MIT speaker cables and may have osilation issues with MIT Oracle cables. The last MIT SPK used with the 180 S2 was the 850 EVO SPK.
