Hi, I am after some recommendations for a stereo amp to use with Amphion Argon 3S speakers. I realise these are not common speakers on these forums... The amp needs to have a HT bypass to be used in conjunction with a Marantz SR7010 AV amp. I would prefer second hand option to look out for. I am keeping an eye out for a Hegel H200 or similar, but any other recommendations would be appreciated.
