Hi Cseriks
I have had the AR D-130 for several years now and I love them. I have used them with Sound Design 3's, Thiel 1.5's and Harbeth ES-7's and while they have worked well with all they are outstanding with the Harbeths, a speaker that likes SS amps. They do not possess that SS harshness, but are rather tube-like in their overall sound. The build quality is typically AR, heavy and durable.
I would not hesitate to buy another AR SS amp.
Regards,
AEW
