Used Parasound Halo A51 5 Channel Power Amplifier. Working condition, been unused for a few years. Sold as is.

Hello Friends: Here is a Parasound Halo A51, 5-channel amplifier (250W X 5), in silver finish. Unit is in pristine operation and cosmetic condition. No scratches or dents. Has been well cared for. Used conservatively, never over-stressed. Was mounted externally (top of rack, in open air) for optimal thermal cycling/ventilation. Unit includes: original manufactures carton/box and packaging materials, rack mounting brackets, original AC cord, user manual. One of the best multi-channel amplifiers available. The best sounding amp Ive ever owned. Those familiar with Halo products know the quality of construction and performance. I am original owner. Priced to sell. Will ship to lower 48 states, only. I am downsizing, moving into a much smaller living situation.

Parasound HALO A51 Five Channel Power Amplifier I have had this amp for a few years and has been used at most once every couple months for my rear channels. The amplifier has remained in my rack since purchased. There are very light scratches on a few of the fins from the initial placement of the amp in the rack, but is sonically perfect.

I am selling my Parasound A51 due to a system downgrade; I have too many amps in the rack! The amp is flawless and is currently connected to my home cinema. I believe I have the box in the loft, so in that case postage would be quite straight forward. But due to weight and insurance costs, expect to pay around £90 for a UPS insured delivery. Collection would be preferred or could deliver within a reasonable distance.Apologies for only a front-facing photo, but the amp is located near a back wall, plus I have XLRs and speaker cables going in, so you can imagine how difficult it would be to photograph the back!If you have any questions, feel free to ask. Thanks for looking... ps: buyers outside the UK please contact me first to discuss your import tax fees, and expect a 3-4 day delivery with UPS.
