Due to downsizing, I am selling my beloved Parasound Halo A51 5-channel power amplifier. $2400.
I have the box and manual. Prefer Michigan pick-up, but may ship at buyers expense. Boxed the A51 amp weighs over 90 pounds.
A51 review:
https://www.audioholics.com/amplifier-reviews/parasound-halo-a-51 I have owned this A51 amp for more than a decade. I used it in my home theater to power the center speaker (Von Schweikert VR4 jr) and four surround speakers (Von Schweikert TS150). The A51 is in good condition with no known problems. (Von Schweikert speakers will be posted for sale shortly.)
