Looking for a replacement micro for the bedroom, at the moment I have a Denon M38 but the volume goes up / down in to big a stages (8 to quite 9 to loud etc), really like the Onkyo CR555 but its output is only 22 watts pc, the speakers I will be using are Wharfedale 9.1 which recommend a minimum of 20 watts pc, which means I will only have 2 watts pc above the minimum, do you think this will be OK ?
