Although you don't know until you try, you'll find that most mass market receivers are pretty bloody awful. Artemus has it right.
Is it worth replacing an old amp?
Let me first apologize if this question has been asked before, I sure it has. I have an old 5.1 setup, Linn AV 5140 and 5120 speakers along with an old Yamaha DSP-A1 amp. The newest equipment I have is an OPPO 205. All my music is digital, where the vast majority being Hi-Res flac and dsf. The question I have is, would I get a noticeable increase in audio quality if I was to replace the old DSP-A1 with lets say a used Mcintosh MC205 or comparable?
