Simaudio 330A

Simaudio Moon 330A power amp in like-new condition. Original owner.
Original packaging and manual. I bought this amp from Common Wave in Los Angeles, 2020. From the box, it went into my system rack, and has played beautifully with the other components in my system. While I've been very satisfied with the system, health issues are making me downsize. So here's your chance to own this excellent amp.

"Magnificent and palatial soundstages, coupled with neutrality, made the Simaudio Moon 330A’s sound in my system wonderful to behold. Its combination of high-quality electronic parts, high precision of construction, manufacturer reputation, ten-year warranty, sexy looks -- and, most important, its beautiful reproduction of every recording I played through it, regardless of musical genre, pace, or playback volume -- easily exceeded all of my needs."
