This thread has become a self reinforcing loop. If you Google problems with the PA5, largely you get referenced to ASR and this thread. A thread/poll like this understandably attracts those with problems with the gear. As everyone here realizes this type of poll says nothing about the real failure rate of the amp. ASR's testing is irrelevant. Amir simply tested performance at the time of the test. In fact, I am surprised 70% of the people in the poll report no problems. I certainly believe anyone with a defective product should get redresss. But, I think there are a lot of people out there happy with the amp.
I think everyone would like to know more about the break rate to understand if it actually makes sense to try the purchase or not. Surely for the performances shown in the measurements and the price at which it is proposed, it would be a very valid amplifier for a myriad of applications in which you do not need a lot of power but you need a clean and quality amplification.
A failure rate of 1% is a speech, 10% is different, 30% a catastrophe.
Another problem, the breaking rate after how much? A month? And after 3? And after a year?
As far as we know at the moment, the rupture rate can be stable over time (those who have the problem manifest it within 1/2 months or will never manifest it) or tend to grow over time, and any unit may be at risk, as far as it is concerned. we know at the moment it could also be that all units could break down within two years.
This is why it seemed strange to me, and also not very nice, that the manufacturer appeared in the Topping LA90 thread to take all the compliments but carefully avoided both this thread and that of the pa5 review in which many asked for clarification on the problem.
All our questions could be answered if someone from Topping gave us an account of the problem, don't you think?
