Quite an outstanding product, at least in the SQ/ price ratio, from a small small company and its weak infrastructure taking us by surprise!? You are are free to pay the premium for some big brand with high marketing and infrastructure costs then.
A high-performing product that seems to be not particularly reliable, especially on launch.Quite an outstanding product, at least in the SQ/ price ratio, from a small small company and its weak infrastructure taking us by surprise!?

Why does it matter even...Your website is still down.
This is not inspiring confidence.
Wouldn't any user simply re-run the process originally used to balance mains vs subs after adjusting the volume pot on these amps, or am I missing something?Reducing the volume using the built-in pot does mitigate the issue, but isn't practical for everyone. If you e.g. have a sub connected to your pre-processor you want don't want to accidentally change the power amp's gain as this would upset the balance between mains and sub.
Yes, I generally agree. That's why I explicitly said:Wouldn't any user simply re-run the process originally used to balance mains vs subs after adjusting the volume pot on these amps, or am I missing something?
The knob also serves as the selector between RCA and XLR and as the manual off switch. The pot isn't stepped and there is no scale or markings on the front facia you could use as a guide.... you want don't want to accidentally change the power amp's gain ...

Sorry, I initially misinterpreted your comment.The knob also serves as the selector between RCA and XLR and as the manual off switch. The pot isn't stepped and there is no scale or markings on the front facia you could use as a guide.
Probably you mean the cases of opamp failure.A high-performing product that seems to be not particularly reliable, especially on launch.
A website is a vital part of marketing for modern companies. If they are not even able to keep the lights on at the web-server, how confident should I be that they are planning and able to be in business for the long term?Why does it matter even...
It's not that they were selling it from their website.
thx! got it...Forum Rules explicitly ask to keep review tasks on topic ...
I got your 3e 5A power amplifier at home days ago it sounds great with my Dynaudio speakers!!! Very detailed and with drive control over woofer, no fatigue, so good!And it has all the things I love most in amplifier:the auto on/off save nothing or even slightly higher than trigger(optocoupler+3.5mm Jack+wire)
Well the best thing I can say for Topping ABOUT AMPLIFIERS is that Topping DAC is my favorite DAC everyday DAC since years ago.The PA5 II lists at € 164.14 on hifigo, but I am not sure if that is an expired sales price, because when you click on it, the price (with 19% German VAT) is € 193.11. But the A5 should really be compared to the PA5 II that has about 40% more power into 4 Ohms. It lists at € 251.33 on hifigo.
I have Amir's results for the A5 and PA5 II copied side by side. Unless the 15 kHz THD+N will tell us a different story, I'd still argue that aside from the power, the PA5 II is still a hair's breadth ahead:
- SINAD is identical
- 1 kHz 2nd and 3rd harmonic are 2 dB lower in the PA5 II (ok, that is within unit-to-unit variation), but maybe more significantly, harmonics in the 12 - 20 kHz range are about 8 dB lower for the PA5 II
- similarly, in the multitone IMD test, the grass in the 12 - 20 kHz range is about 5 dB lower in the PA5 II
- in two-tone IMD, 18 and 21 kHz products are about 2 dB lower in the PA5 II
- for the next order (16 andd 22 kHz), the PA5 II is aobout 8 dB lower
- (for the products around 38 kHz, the A5 is about 15 dB better, but I think this is owed to a steeper output filter rather than better transfer function linearity)
I did a similar side by side with archimago's tests of the A5 and PA5 II Plus, and they were more like head-to-head regarding SINAD and IMD, and with a (smaller) edge on output power for the A5 (4R: 121 vs. 102 W, 8R 62 vs. 56 W).
So other than the 10 - 20% higher output power (depending on whether you look at 4 or 8 R and the Plus version or not), I do not yet see what the A5 does better, even if it comes close or maybe draws equal.
How does the A5 achieve higher power? It does use 2x TPA3251 whereas Topping never told us what chip they use or how many.
What’s the brand and model of this line stage?…And if you believe in volume control quality like me and the crew of audiocircle forum, for preamp (line stage) that malaysian transformer volume control line stage they talk so much pages
subjetively in my case yes, but yeah is not lab proof statement but for my ears, class D/B with external smps PSU sounds WAY warmer and not listening fatigue than purifi/hypex with internal hypex smps psuis there any evidence to suggest these will be as non fatiguing as the hypex or purifi class d designs.
Promitheus TVC preamp more info in other forums like this https://www.audiocircle.com/index.php?topic=31621.0What’s the brand and model of this line stage?
