I have a Marantz SR5009 that I bought in 2014. It's been a good amp, but within the first year I had it, something inside went, resulting in it bursting into smoke that filled by home theatre room.
I had it fixed under warranty.
Then two weeks ago, it stopped working a second time. I brought it in to a repair shop. There, they said that Marantz isn't as good as it used to be, and I might consider buying something else.
They said that they have a lot of difficulty getting parts, and have had those problems for about 5 years. They mentioned that parts might take months to arrive in the current environment. I know I bought something else earlier in the year that had to be shipped from China. It cleared customs there on July 7 and it still hasn't appeared in the tracking system for my own country's mail service. So it's stuck....somewhere.
Now, the repair shop just got back to me tonight, indicating that the "Output Stage" has blown and will need to be entirely replaced. They've given me a quote of $320 to repair the amp. That's less than buying a new one. But I'm not entirely sure how long it'll take to get parts. And admittedly, this amp is one that lacks Atmos, which is something I hoped to migrate to.
I just don't know if this is an excessive amount to spend to fix an amp or not. And I'm concerned whether the fact that this amp has blown twice is a problem sign. I had a Yamaha amp for 11 years and never had a problem. Then I get a Marantz and it blows twice in 7 years.
