Yes, I am thinking about changing my D3020. When Brio R was introduced I was really impressed by it. I was one step from buying it when I figured that I could buy NAD C326BEE for over 40% less than the Brio R. It was an easy decision to make and it appears that I was lucky having in mind the number of people having problems with a noisy transformer some Brios had.
After a few years, I moved to the D3020 and to this very day this amp sounds great and it is a spectacular value, especially here in Canada at around GBP 300.
Based on the reviews I was able to find, new Rega is a very fine amp. I am simply trying to find if there is something I should know before making a final decision.
