I’m going thru McIntosh he!!

I’ve been having lots of trouble with McIntosh processors;

First one was a MX119.  Went dead on me - no picture no sound despite 2 visits to an authorized McIntosh repair shop.  They gave up.

I took it to the shop where I bought it.  They traded it for a MX120 along with some cash.

The MX 120 went on the fritz after a couple years of ownership.  Audio and video blinked in and out.  Had to turn on and off to get it working again, unplugged it from the back and let it sit.......

I went to another McIntosh authorized repair and sales place and I asked whether they could fix the 120.  They said it was an old unit and it was a gamble whether they could get the parts.  They said it might be 2 boards.  Then, they offered me a lightly used 121.  They gave me an allowance for the 120 and I paid a lot of money on top of that for the 121.  They told me the 121 was lightly used by a rich person and wanted the latest.  Told me there was nothing wrong, impossible that anything could be wrong with the 121.

Now the 121 has the following problems:  sound, no video;  video, no sound, nothing altogether.  The 121 is an outright lemon.  I am going back to this shop to get my money back.

So I want to ask, are McIntosh processors really that bad or have I been incredibly unlucky?  Feedback please.  Is McIntosh listening?  Thanks for looking.
