I have used two D-240's for more than ten years. They are
tremendous amps, wonderfully musical and reliable. The first was a MKI which at that time could be upgraded to a
MKII by ARC at no charge. I prefer the sound after the upgrade although I didn't have it long as a MKI. I had a look inside before I sent it away and on it's return. The
changes made were substantial. I've never had a reliability issue with either one. I listen to them every day with Proac 2.5's and Tablette 50 sigs.
