I have heard but not used the Audio Research D240 myself.


I have heard but not used the Audio Research D240 myself. It seems similar in nature to my solid state ARC amplifier, the D130- which I think of as very similar to the D240 and really like- amazingly neutral and cool running. In my view, the D240 is one of the best ARC solid state amplifiers: the 100.2, D130, D200/300/400 and the D240 are my favourites.

It’s been awhile since I heard a D240, and don’t know that I an comment on a MKII as compared to MKI, but I remember the D240 as smooth and nimble and quite neutral. Given your “slow and relaxing” concept, I’d be curious as to the other gear you’re using with it- I thought it was quite fast and dynamic- pleasantly so.
