Howie,
If you can, do try a pair of Audio Research REF160M on your Aidas. They can be run in triode mode, but some extra sweetness. And you can then see how the Aidas do with a little more power, before replacing them altogether
cheers,
Alex
I have heard them driven by Mcintosh 2301 300 watt monoblocks at length. I have to say it was horrible for some reason. I almost didn’t buy the Aidas because of that demo but luckily I heard them in another system. The new AR look great.
