I’ve owned an A23+ for the past year. Im using the preouts of a Yamaha flagship receiver in a 5.1 professionally calibrated system for audio and video. The Parasound is one hell of an amp! I can’t find any fault at all in its sound. It delivers plenty of power into my 4 ohm speakers. It’s damned near perfect for home theater AND 2,1 channel audio with Vinyl LPS as the source. I got curious about these new Class D Gan amps and bought a powerful one. The Parasound crushed it! It’s more visceral, dynamic, better midrange, tighter bass, tonality, etc. The only area that the Gan amp matched was soundstage and a clean high end. Toes just weren’t tapping with the Gan amp. It was lifeless in comparison. I put the Parasound back in and the smiles returned.
