“I have owned the A21+ for years. Purchased here from Audio Advisor.
I chose the A21+ based on the Stereophile review which stated that the the architecture is stable down to 2 ohms. I use the A21+ to run a set of Revel Ultima Salon II's which have a noted drop to ~3. 6 ohms. I have not experienced any issues, and when I close my eyes, the soundstage is pure bliss.
Highly recommended.
I would definitely buy this product again”
