I know this is going to start something on here but I have used several amps with a set of EROS mk2 and now on Mk 3.5.
Bryston 4bst and7Bst. Ear 519 Tube and finally a set of Atma-sphere Ma1 Silvers both as stock and now with resistor and power supply upgrade by Atma-sphere.
The Ma1 OTL amps are without a doubt fantastic with these speakers. The brystons were good and the 7B's are known to drive difficult loads but nothing I have heard sound as good as the silvers. I do use Speltz autoformers with the speakers. I find that I don,t actually need them but I was told they may prolong tube life?
Another heresy is that I no longer use the internal crossover amp on the base speakers. I have found that tube amps sounds better on bass also. I realise what I am saying here but I trust my ears and this was an easy call.
Definition of transparency must be this set up.
