I'm looking at bi-amping using Arcam gear, either the C31 and 2 x P38's or an A38 and P38. It has been suggested that I will get a better sound with the separate pre and power amps but that is the more expensive option. I like the sound of the Arcam amps they seem to go well with the Monitor Audio GS20's I have (although I realise that Arcam is not to everyone's taste) and I'm embarking on this with some trepidation as they will replace the A32 and P35 I recently bought having lost the first P35 to a fault and it's replacement to the same fault. Any thought's on the best combination?
