Purchase breaks well within 30 days

Four to six months seems like a long wait.  I might try to politely talk with someone about the possibility of speeding things up.  Something mentioning it's the best DAC you ever heard and you are anxious to get it going again.

First of all I appreciate all the opinions surprised so many adamant ones.

Neither party is a dealer.

The transaction was not the one in my transaction history.

I have bought a lot of used equipment just not on Audiogon but rather from dealers in the past.

Nothing has ever broken in less than 30 days let alone 6 months.

My point perhaps not properly emphasized was that the repair is not trivial but rather necessitates replacement of the entire board of the dac.

I agree if repair minor of course return not appropriate.

But where repair substantial and will not be completed for 4-6 months and occurred so soon after purchase I would expect seller to be more understanding.

I guess you guys think the deal part of buying it used means you lucky it works at all.

I think its also relevant to consider that this dac purchase was expensive.  The dac sells new for 6K and I bought for 4K and was told its like new.

My expectations are higher if paying a lot and discount was good but not much more than some dealers give for new.

In conclusion I am not demanding anything from seller just expecting more for premium price sale but you guys have calibrated my expectations.  I would have taken back if repair substantial and wait long and premium product advertised as like new.

I will focus purchases from dealers especially now going forward as the prevailing sentiment here seems to be that you got a deal so you lucky it works at all or has a warranty is a bit too cavalier for my taste.

I'm surprised that the manufacturer hasn't stepped up and offered you a new replacement since the repair time of your unit is excessively long. It would certainly be a nice gesture on their part.

Say you purchased an expensive used vehicle from someone and the price included a free bumper to bumper warranty. A few weeks later the engine blows. Mechanic tells you you are to receive a brand new engine at no cost to you, but it will take some time. Would you demand that the guy who sold you the vehicle take it back, or would you be stoked about receiving a free brand new engine? It seems to me your gripe is you simply don’t want to wait so long to have it repaired.

If I bought a premium car would expect sale voided....if bought cheaper car different story. 

Premium product sold as premium deserves higher standard.

I would take car back fix it and sell it again or offer buyer premium discount for inconvenience.

BTW The dac manufacturer is low on new inventory due to covid so would not expect them to give me new one...
