Adcom?

Does ADCOM still make products and most importantly sell products?

I bought a amp/pre-amp combination (710 for the preamp and maybe 5300 for the stereo amp), and it was the worst electronics I have had in my house in 40 years, that is, beside NAD.
Both components started to malfunction majorly just after a few months (pre-amp volume control having a mind on its own, amplifier was discharging loud every couple minutes).
They both times promised me that they would exchange mine for new, so after agreement, I sent my gear back to them, and they sent it back to me with the same problems... we did that a couple times.... I think the tech guys were billing the department for new units, kept them for themselves, and sent me back the same crap untouched.
I could tell both times that the gear was untouched by adcom as I had marked the units on frames.

I feel like this kind of fraud is happening a lot, especially this time of the year when audio gear dealers offer "black friday deals", but in fact, they sell refurbished units thinking you won’t see anything.

Adcom, dealers selling refurbished as fresh from factory, thoughts?
