I have has my Cyrus One amp for ever, this is one of the very first units, I recently bought some new Mission speakers, QX2; today amp went dead. All three internal fuses ok, power into unit OK. Just looked on Cyrus web site £300 quid for a service/repair. Do I do this or look for a new amp, and if so what can I get similar performance for similar money, do I stick with the good old stuff, or go new. Hand on heart I think I would like to have unit repaired if possible but could be swayed or common sense prevail.
