This is a like new Parasound Halo A51. I purchased it from the original owner who used it very lightly for home theater. I used it for the past 4 years very lightly for home theater rear channels. I have now downgraded my home theater and no longer need it.This week I had it serviced at an authorized repair center, Adams Electronics, and they replaced the power relays, effectively renewing the amplifier to like new condition. I can confirm listening to the amp w/ sensitive speakers I hear no audible hum or defects.I see no cosmetic defects whatsoever, I provided pictures to confirm.I also am selling another Parasound Halo A51 amplifier that has been cosmetically damaged, whichever amplifier sells first, I will keep the other. I think that should speak to the quality and condition of both of these amps as I am willing to keep one of them.Please send offers with address so I can calculate shipping costs appropriately.

This is a Used Parasound Halo A51.  It arrived to me damaged from shipping w/ a crack/dent on the front top right corner of the faceplate and heat sink.  There are some additional difficult to capture scratches on some of the heatsinks and the P light has a scratch on it.  Rear terminals all in great condition w/o obvious signs of damage/wear.  Most of this is imperceptible from >5 feet away.  Otherwise the amp works perfectly, I used it w/o any issues for 3 years for atmos channels in a home theater.  I am only selling because I have downgraded the home theater. This is a great opportunity for someone to get a phenomenal amp for a discount d/t cosmetic issues.  Please inquire if you would like more pictures of the item. Ideally looking for a local sale since I do not have the original box.  That being said, if someone is willing to pay shipping costs I can arrange for them to be shipped in my other A51’s box.

Parasound Halo A51 5 Channel 250W Power Amplifier. Great excellent condition. I own 2 of these as I was going to Bi-Amp my B&W 803s and I never proceeded with that plan. I bought this from a licensed dealer when I built my house 6 years ago as a barely used and fully tested model. Before I decided to put this up for sale I had it completely checked out and refreshed with all critical capacitors replaced in all 5 amp modules. Yes, there are literally 5 separate amp modules in this Bad Boy. Includes Power cord. The Halo A51 by Parasound is one of the best Multi channel amps available. If you dont know the Parasound quality, please google some references and you will hear ... and all the hype is deserved. The amp will be shipped in the original double boxes. The unit is cosmetically clean and functionally/sonically perfect. Please let me know if you have any questions. If you are not satisfied, unit can be returned less shipping cost, and at buyer expense. Please visit Parasound.com to see full specs.

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.
