Yes there are II many plans.Are there any plans you could disclose about a future Pa5 successor? Something in Pa5 price range.

Non voglio rispondere ulteriormente per rispetto di chi apre il thread e vuole leggere di Pa7 e non di altre questioni, quindi chiudo qui l'OT e mi scuso.Trattiamola solo come dichiarazione solo tecnica. Non sto dicendo che Topping non sia da biasimare, ma quella critica verso JohnYang1997 è un po' dura IMO. Molto probabilmente non ne è responsabile.
Do you think Topping sold only to the couple of hundred ASR members? Could it be that as they don’t have a support forum, and known to have unsatisfactory support, every failed owner came to ASR to vent their anger.My PA5 is still in operation, but after seeing nearly 50% of these fail in the ASR population
Will you design a three-channel power amplifier or a seven-channel amplifier for home theater users?The Non plus version has slightly less power for 449 USD.
PA7 is released this long after the PA5, because we spent a very long time identify and fixed the previous failure rate issue of PA5 and made sure it's not an issue anymore on PA7. I'm very confident with the quality of the new PA7 . The non plus version has superior performance to cost ratio and it's highly recommended.
I don't think it's an unreasonable request to ask if they'd consider an upgrade/trade-in path for PA5 owners that haven't had failures yet. They are fine to say no obviously, but no harm in asking.Do you think Topping sold only to the couple of hundred ASR members?

You may also have missed their response to the failures.
As far as I can tell their response was only talk. They responded to me on multiple platforms (here and reddit) but then suddenly went quiet when I actually asked for help.Do you think Topping sold only to the couple of hundred ASR members?

@JohnYang1997 any answer on this ?I see that PA7 and LA90/LA90D share the same connector. Would it be possible to use the PA7 power brick (52v/6.5a) with the topping LA90/LA90D ?
Thanks. I had been wondering. I will be very happy to see this new PA7 earn a good reliability reputation. I am sure the PA5 experience was as difficult for Topping as it was for the customers. I hope the resellers learned to respect the customer just a bit more too...In short, majority of the failures come from the sealed module, and it's the opamps that are overheating. It wouldn't have been an issue at all if someone hadn't copies and patented our earlier designs that we wouldn't need to make the module. Too many opamps in a small package is not a good idea. In report in the repair department, there's pretty much no damage done to the chip itself and no DC would ever appear across the terminals. Anyway lessons learned so no more than 2 opamps in one small module is our rule of thumb.
I second that thought.
I purchased a Buckeye NC252 from Dylan for a similar price (US$575 plus shipping to Aus) and am extremely happy as it is very clean (SINAD 94db) and powerful (150W into 8ohms). When you take into consideration US assembled vs China, and the failure rate of recent Topping amps, it is IMO a no brainer.
Good to see you back on the forum!Yes there are II many plans.
Yeah, it wasn't 50% defect-rate, but... Multiple customers got two bad units, some got a replacement that went bad, and the fail units displayed similar symptoms. So it has the appearance of a pretty large systematic issue, and Topping and the resellers admitted this at various times. Which brings me to:Do you think Topping sold only to the couple of hundred ASR members? Could it be that as they don’t have a support forum, and known to have unsatisfactory support, every failed owner came to ASR to vent their anger.
Yes they said this, but that was it... People still struggled to get after-sales service on what should have been straightforward product warranty. It took me almost a year to get warranty on a unit that broke the first week, and this response did nothing.You may also have missed their response to the failures.
I was only commenting at the figure...Yeah, it wasn't 50% defect-rate, but...
Linearity is where PA7 loses me.Comparison of pa7 vs pa5. Seems in these two metrics pa5 performs better. Then people can argue if it's audible.
I think that is a pretty cool idea. Even discount worth half of pa5 would be lot better than nothing, and would get customers that feel burned to maybe spend money on another Topping amp.I don't think it's an unreasonable request to ask if they'd consider an upgrade/trade-in path for PA5 owners that haven't had failures yet. They are fine to say no obviously, but no harm in asking.
That’s an interesting idea as a preventive measure… Did you use passive or active cooling?Linearity is where PA7 loses me.
(and it seems I was right to add extra cooling to the PA5 I used to have...one learns a thing or two from years of building PCs)
