The A-8500 is labelled to handle 4 ohm loudspeakers. Also, being of the Integra series, the amp should meet the needs of the hifi enthusiasts.

This amp has very neutral sound to it, some might even say the sound is flatish in the low tones. Still, the sound is very pure. Apparently, sensitive loudspeakers would help to get the most of this amplifier.

Soundwise, quite alright. Also, the wide range of audio sources is alright, for instance the two CD-player inputs. And the phono [turntable] input switch between MM and MC cartridges is of good thinking. The quality of the audio source switches, could and should be better: contact problems are an issue.
