Ask your dealer why it's so expensive and what they do. If they replace both power amps as a whole go for the repair. 600€ for another 10 years seems fair then.Thank you all for the replies.
I also find the repair very expensive (and it could be 600€ with the added shipping).
I only got the information that the repair costs 545€. I have no clue what will be changed.
Yesterday was the ultimate day I had to decide. And I have said to just let it come back broken.
Today he said if he should ask if there is still some guarantee on it. I said that that would be great.
I have also asked why the repair is so expensive and what parts would be replaced.
I have now already got an email back and he said that everything will be changed, only the power supply stays the same.
Then I recommend to get it repaired.I have now already got an email back and he said that everything will be changed, only the power supply stays the same.
Can I ask what information you are basing your class d reliability expectations on?
Without knowing what the fault is with the Lyngdorf how can anyone conclude it is inherently related to it being a class d design?
*ALL* electronics can and does develop faults. Plenty of faulty class A/B amps out there
BTW myself and Bliman have already discussed off-line so I'm not trying to steer anything
Other things to consider are performance and sound of old verses new, efficiency and running costs of class a / a/b v class d
Again, I am biased. I have 20 year-old Class AB amps that are still running, close to spec. I’m a “buy-and-hold” audiophile, so I like units that last. Also, the older AB amps are still serviceable without complete board replacement.
Every audiophile gets to pick their own value proposition. My is “long-term performance”. AB amps can deliver that in spades, if they are initially designed and constructed well. I am skeptical of Hypex units because I’m not willing to trade a few dB of SINAD for long-term performance. Especially when speakers are involved with 10x+ THD levels.
Exactly. The class of the amplifier isn't important, the method of manufacturing, and custom components is. The beauty of older amps is that they were made using standard components and with through-hole mounting so easy to replace. There's hardly anything in a Quad amp one can't buy on-line.Modern surface mounted class AB with its many ICs is not particularly repairable either in many cases. My old Quad 606-2 could be completely refurbished precisely because it uses discrete components.

That entirely depends on the design.It really just comes down to the replaceability and longevity of parts. So, my bias is that the parts replacement in Class A/B amps is more straightforward and less inclined to availability issues than in Class D amps. This is based on the experiences I and colleagues have had in getting amps repaired and the associated effort involved.
Granted, my experience is more limited than others on the forum. Hence, my assertion of bias upfront. @restorer-john likely has much wider experience to speak from.
Did you end up getting it repaired?My retailer said that he doesn't really trust Class D anymore. The reason he said that if something is wrong then most of the time it has to be replaced fully.
Now that is a bit ironic because here everything will be replaced as well if I choose to repair it.
