Yup. They expect you to throw out the "old" unit & buy the new. A replacement amp module can cost almost the same as a complete new cab. Crazy.   Dead

That is a very good point Earplug. If they really want things to be sustainable, for God's sake give us half a chance and at least make them repairable. It's not like that powered  speaker you are repairing was a 10-quid toaster, it's over two and half grand. 


Yes, exactly. Those are not cheap, but all the more reason I wouldn't touch anything like that with a barge pole. You limit your options straight away.  

It's interesting how some companies go that way and then you have TWA, or d&b audiotechnik that go the passive & external DSP/amp route. Or some, like L'Acoustics, EV, etc. that have both. I know which I prefer.   Smile

Yes, I feel your pain, but back in the 1990's there were maybe 5-6 billion people. We now have over 8 billion.

This guy explains it perfectly:-

"i call this evolution!!"

Or privatization! Always a good idea. Just look at the UK water companies. Pumping shit into your home!

Or the North Sea gas debacle. Just compare to Norway, where the money was put into a public sovereign fund, for the good of all, not just a few City investors. It does make you sick...    Dead

I think a lot of the failures in modern amps stem from the use of cheap components which have a much wider tolerance than good quality closer matched ones. This also means that it's likely even 2 boards from the same production line don't sound exactly the same.

Yes,i had loads of amplifiers on my hand that had nothing to do R ch with L ch,i also found tottaly different parts in new amplifiers betwin R and L channel! this is another reason that i don't wanna hear about ,,new stuff'' at least you pay crap money for crap stuff,so form this point of view i'm agree LOL

Its kinda comical. I worked for a well know hifi company in the early 90s, which had bought some dead brands and started churning out stuff in China. I compared a few of the internals, and as you say, the same models often had different parts. I remember demoing a dac for a friend, I got 6 out of stock and we settled on the one with the least transformer hum...

When JBL first started making their 10inch K110 driver in the late 60's-early 70's, almost 90% of the production failed to meet the strict response criteria during final testing,and were all sent straight back for re-coning. So when you actually purchased one, it would be totally correct.
Can't see that happening today on any audio product. If it turns on, will be sent out as passed. Ermm
Be seeing you.
