Two defective pieces in a row - unreasonable to demand refund?

Much depends if you paid by debit card, or credit Cardas where the card is from 
I tried to get a refund on a defective product ,after it was sent back
and my bank wouldnot back me, horrible little crappy bank 
webster5 cent savings.  If bought buy credit card then file a claim 
tell them you have no faith and waste of time .
tell your dealer to hold off on sending anything .
since they have the product back. The ball is in your court .
if they ship it after you said no put a note on your door in big letters Return auto Sender then you will get your money back.

McIntosh fort sure is not the same ,No longer owned by audiophiles for years now.I sold Mc and parts quality is average at best , nice meters , but Waay over priced . Owned by a Korean company with just $$ profits in mind IMO.

I bought a new C49 and the remote was missing from the box. They sent me a remote and tried the unit and the headphone jacked hummed, so I returned the unit for a refund! Completely turned me off to McIntosh.

I'm with @millercarbon. Get out from under the Mac and get something reliable that performs better for less $$$. Lots of options in the marketplace, new and used. 

Google ANY major company and you will get a litany of lawsuits and complaints filed against them. Including all audio brands.

This knee jerk reaction to jump all over McIntosh over something that has happened to EVERY BRAND on the planet says more about the nay-sayers than anything else.

And I'm with the person who said get the third unit. Cosmetic flaws are not manufacturing QC issue, but a transit issue. The DOA unit is legit, so let.them replace it.

If  Mac sounds good to YOUR ears, go with it. Any brand you pick can have issues. That's what warranties are for.

My two cents.
