Well I heard them both side by side for a long time. The Ref 110 has more bloom but the HD220 has more slam and bass attack. Also I felt the HD220 is more synamic. For female voices the Ref110 was better. For Jazz and pop music the HD220 was much better to my opinion.
Overall I preferred the HD220. If it is better than a big Krell for example I do not know. I found the sound very good, much better than any ARC solid state amps I ever heard. I found their solid state amps horrible and the HD220 fantastic.
