I popped two speaker fuses into the Arcam Delta 60 the other day, and it sings. I decided to put it in place of the Cyrus 2 in the shop system, as the Cyrus needs the source selector cleaned. To my surprise, the Arcam, bone stock, walked all over the Cyrus, even though I had done a complete recap of the Cyrus' preamp section with audio-grade caps. I have put way too much time & money into that Cyrus. The Arcam is there to stay.
