Amp Warranty Repair - What's an acceptable timescale for turnaround?

Is a long time yes, BUT, if is returned as same cond shipped, and works perfect, meh, what’s a few weeks, to get you back jammin to tunes 

   Patience.  Happened to me, but I received it back same as when shipped, I honestly think, they just said, “let’s hold this for a month and a half, ship it back, “

he won’t know, brought to a very good audio shop in northern illinois, in 1.5 weeks, it was fixed, cleaned, for 175$

I sent the copied receipt to the company, with a nice hand written note (wofe wrote it)

they apologized massive, sent me a huge box of nothing.

lasted a couple more years, then did a office space copy machine beat down to it.

wont buy another component from them ever again
they dropped the ball on a expensive once, they were supposed to be a good warranty known company. 
 

if it’s returned in fixed, great cond,…go with it  

Which is why I’m loyal to Audioquest, bought a pair of nice Xlr’s in early mid 90’s, about 3-4 years ago, I hooked em up, there was a wire which had broken 😠 snide the jacket, sent them in, they phones me, said all fixed, there n the way back to me

love that lifetime warranty. They are a good company.
as is Klaus at odyssey, and Roger from Sanders sound. 
but, if I have other issues, I will drive the hours to northern illinois for that mom and pop audio shop.   Somewhat introverted in personality, their work was / s very good  

be specific, what amp are we talking about here, and what distributor

My recent experience with Parasound.

I had my gear back in 10 days.  Warranty expired.  No charge...

Pretty good service IMHO...

Buying for warranty, Bryston and Parasound are tops in my book.  Of course, they don't pass the audiophile price test for a lot of folks.

This is not warrantee related but nevertheless relevant. I just had one of my MC30s worked on by audio classics that I sent up the first week of January and it’s still there ready to be shipped back this week. I fear it’s going to get worse because the shortage of technicians working on audio gear and the amount of gear needing to be worked on. My experience anyway.

Mine was not a warranty repair, it was actually elective surgery I sent her in for😁. I have a Simaudio Titan 5 channel amp that is 20 years old. I bought her used a few years ago. Though she was super clean and sounded every bit as good as I had always dreamed, it was a 20 year old amp. I contacted Sim HQ in Canada and though the rep stated they "overbuild" their amps and that "every single Titan is still out in the field" it would be a good idea to send it to them for cleaning and calibrating. This was at the very height of Covid when literally everything was shut down and you couldn't even get in to Canada. The rep told me about 4-6 weeks. It ended up being a little over 8 weeks. But again this was at the very height of Covid so to be expected it would take longer I guess...And mine was elective as I said.

Your situation is different, and yes this is bad communication/service. BUT take him up on the loaner! I ended up buying a Monolith 5 channel ($1299 at the time so I figured why not?) to fill in. Though this amp was nowhere near the class of the Titan, it did get me through. The silver lining for me was as soon as I got the Titan back and connected her I was truly truly awestruck! I think a lot had to do with it really hit home how different amps can sound and what an affect a higher end piece of gear can have on your system. Made me appreciate the Sim all the more...

I ended up returning the Monolith and got a full refund!

Best of luck my friend...
