@reubent That ARC integrated is a nice amp. Likely gets the most from the Sony speakers.
Got me to thinking about a somewhat unrelated subject regarding persons just getting into audio on a restricted budget. My advice is to purchase a quality 50-100wpc amplifier and source component then spend the rest on the speakers. The result is ownership of an amplifier at a higher cost than the speakers. There are budget speakers available these days that when driven by a quality amplifier sound quite good. Time can then be spent enjoying current system while saving funds for better speakers after obtaining some idea of one's preferences prior to making the next speaker choice. My thinking is that speakers provide much of the character of a system. One needs to know what 'character' they are listing for and then search for the best quality of speaker providing said character.
