@Divakar - My musichall is driving the thiels perfectly.
I already know the sound signature.
It is 50w@8Ohm and 100w@4Ohm.. Surprising I would say.. Considering M3i struggled..
Its singing as I write.
@Blasto, as you know better than anyone, it is only the side by side comparison that reveal the difference When I first heard the M3i drive the Thiels I thought they were sounding great especially compared to the Quads. Then when I had the A1008 hooked up all the flaws of the M3i became apparent. Not really flaws as much as what was lacking. I bet when you do this exercise with the A5.5 it will be apparent
