Sonic Similarity Analysis
Both are mid-tier integrated amplifiers with excellent phono stages and natural, detailed sound signatures. The A-S501 offers more power but maintains the AU-517's emphasis on musicality, warm tonality, and solid construction, making it ideal for vinyl enthusiasts seeking transparent, engaging sound.

What pairs with this?
Reverse-match works both ways. Point us at a receiver and we surface compatible vintage speakers and turntables — matched on power, impedance, and era. Point us at a pair of speakers and we surface receivers with enough headroom to drive them cleanly. Available on Pro and Flipper Pro.
