Manufacturer Repaired Dropped Integrated Amplifier - Should I Be Concerned?

AudigoN Team,

Question for you on a gently used solid state Class D integrated amplifier that I have the option of purchasing.  This unit was damaged in shipping as it was dropped by FedEx.  Because of the drop, I have the option to keep the unit after repairs (presuming an additional price reduction is offered to me by seller) or get my money back.

The speaker wire attachment post near the edge of the unit and the post attachment mounting surface were bent by the drop.  No other signs of visible damage.  Unknown if there is internal damage, because manufacturer instructed me to not power it before repair.  Unit on the way to manufacturer and manufacturer will repair and has stated that the warranty will be honored after repair even though the unit was dropped - didn't expect that!

Should I be concerned about the long-term reliability of this unit assuming that all visual damage is repaired and that the unit is power tested for functionality?  There is a price benefit over a new unit on this and depending on price adjustment, possibly over another used unit.

I presume that all electronics are designed for some level of acceleration based event during shipping.  Please provide your thoughts - with the assumption that the repaired unit is initially functioning properly and the warranty is still valid.  If this was your situation, would you pass on this or would you consider this still to be a viable option: a) if no internal damage was found, b) if there was internal damage to sensitive electronics that was repaired which would indicate that the integrated amplifier received a significant impact?

Thanks in advance.
  Hi, sorry to hear about your unit. Maybe I can shed some light on this for you. I sent a McIntosh tuner from California to New York in 2016 for upgrades and modifications. Due to negligence on the part of the seller on how to pack the unit, it was dropped by the seller. The man doing the upgrades actually called me on the phone to tell me about it. He said the front glass was damaged and there was a small dent in the chassis. The front glass was replaced, no charge, he performed a needed alignment, no charge, and did the upgrades. That was fine with me. I never did look to see where the dent was in the chassis. The entire unit fit upon return  nicely into its McIntosh wood cabinet. It has performed better than new since I got it back. The tuner model is a MR-74 that I bought new in 1980. Its specs now read and it sounds as good as my MR-78. So, I hope that this helps you. It is good to know the seller, the company, and McIntosh units while not unbreakable are pretty much bullet-proof. Your manufacturer has given you good options. It sounds like a good company. I don't think you lose with either option. You can get your money back and start over, or accept the repairs with a full warranty at a discount. .I am curious what others will say. Good luck! 
If the manufacturer signs off on the repair, I don't see any reason to doubt it will function as new.
If the unit sustained cosmetic damage that wasn't repaired, only then would I ask for a discount.
A "once over" by the manufacturer, even replacing the odd part is never going to identify subtle damage that does not reveal itself till much later. On the other hand, a deal is a deal. See how big a discount they give and base your purchase on that. Maybe they will give you not only warranty but an extended warranty. A drop in price of at least 25% will cover at least one future repair.
To be more helpful, imo it would depend a LOT on the manufacturer. Reputation, quality, etc. If it's a small company� with less exposure and longevity, you don't even know if they will make it long term. A problem could show up in 2 or three years. Will they be around and will they stand behind it? If you don't know the answer to that, then it's an in the moment risk reward question. IF the discount is extreme, I might take a chance on it. But, you would get nothing for it down the road if you ever sold it. If you buy it, be prepared to accept it as write off for resale. 

Damaged goods as repaired well is a legit way to get good gear on the cheap, as long as you know you don't get ahead long term. It's best for buy and hold strategy. YMMV 
You are probably ok if the manufacturer servility, but personally it would bother me enough to get a refund and buy another one.
I wouldn’t buy it. There may be cracks in one of the circuit boards that may eventually give problems.  If you bought new, I would ask for a new one.  If bought used, I would pass on it.
