Please share the schematics reference. That cost forces me to guess quiescent current is 100mA, and your loudspeakers have got fantastic sensitivity.Only cost me about £40 to build

The higher the frequency, the greater the distortion at any power level.Friends, can anyone explain this output in easy words?
Thanks, but is it an audible concern?The higher the frequency, the greater the distortion at any power level.
No, unless the speakers are incredibly inefficient and difficult to drive. In that case PA7(+) and many other amps are a better choice anyhowThanks, but is it an audible concern?

ok, the left axis is Total Harmonic Distortion and Noise. E.g. - 60 dB is 0.1 % distortion and noise in the signal. - 70 dB means 0.0316 % and - 80 dB means 0.01 %Friends, can anyone explain this output in easy words?

PE: I have gone through Amir's video, but want to confirm if I am getting this right.
Thank you in advance
Have you any facts if we say about PA5 II (rather than PA5)?Buying the PA5 is a bit risky
There is at least practically no visual difference between old and new in the inside. No new design for getting the heat outside! Time will show. Here is the Poll for the old version:Have you any facts if we say about PA5 II (rather than PA5)?
There has been a design change in the area the previous model failed.There is at least practically no visual difference between old and new in the inside. No new design for getting the heat outside! Time will show. Here is the Poll for the old version:

Poll for Topping PA5 owners only please.
Poll for PA5 owners to report product defects. Discussion for any solutions. I think it would be useful to get a handle on some numbers to estimate just how wide spread the issues are. Addendum: Here is Topping's response to the PA5 issues...www.audiosciencereview.com
I guess, after the known problem this problematic place with it's new incarnation is the most reliable circuit on the planet - Topping engineers are great, and having the object to apply their brain they did something very robust.There is at least practically no visual difference between old and new in the inside.
My PA5 II Plus hasn't shown any issues for the month I have it in my system. I keep it on all the time. In a room at about 26-26C, I measured case temperature of about 33.5C in idle.There is at least practically no visual difference between old and new in the inside.

I don't think soThanks, but is it an audible concern?
I think you’re right: if you are in for high performance gear at this price point there always is a customer trade off. On the other hand, Topping also sells much more expensive stuff, aimed more at the high end market. The PA5 may have been an expensive glitch for them, reputation wise. I’m not sure if a reputable audio company can cater for both the low and high end market nowadays, as internet is unforgiving.My PA5 II Plus hasn't shown any issues for the month I have it in my system.

1 month period is too short for conclusions, but the amp has no obvious issues so far. I have more info in my lengthy post #459.
About the warranty service, at this price, be realistic. I've had issues with similarly priced electronics from "reputable" brands like LG, Samsung, Oppo etc. Below certain price point you can't expect any real service or care, they try to push you away or to confuse you by transferring you across the globe between departments until you eventually give up. So the choice here is risk vs price, imo.
If it was 80k$ amp you owned and a company sells 3 per year, they certainly would know you by name when you call them... Less than 300$ amp is just a commodity sold by the thousands. You are expected to buy the next model in 2-3 years time anyway. I think that Topping is not worse than the others in that respect. If my PA5 lasts 3 years I'll definitely consider it paid off... I don't expect to own it 20 years from now.
By the "definition" of hi-end nowadays ($5000+), I don't think Topping even touches on the entry level hi-end... I'm not talking performance of course, because that seems unrelated to the hi-end perception, which is mostly brand, looks and price.I think you’re right: if you are in for high performance gear at this price point there always is a customer trade off.

The conflation of "High End" with "High Price" is basically all that is wrong with the industry.By the "definition" of hi-end nowadays ($5000+), I don't think Topping even touches on the entry level hi-end...

I agree with you that it's difficult for one company to serve both ends of the market at the same time. It requires different mentality in design. I remember how disappointing was for me in the late 90s when under the cover of an Audio Research CD player for 4k was found $200 Philips 721. A magazine at the time caught them on that. Basically, it was the Philips CD player in a fancy box. And I remember how funny Audio Research tried to explain that they improved vibrations in their enclosure and turned the cheap player in a hi-end unit... And Audio Research was a real company, compared to other "extreme hi-end" crooks.
Are you sure you're not mixing up Barclay and Marantz? Another notorious rebadge was the Theta Data that incorporated a Philips universal player.By the "definition" of hi-end nowadays ($5000+), I don't think Topping even touches on the entry level hi-end...

No. It was Audio Research and Philips. I remember because a friend of mine had the exact same Philips CD player. I've seen other examples after that, but for me personally was the first time when I got the idea that something is not right with the so called hi-end. I follow this industry for very long time. More on the electronic design side, not marketing. I think many companies are great and professional at what they do, but there are others who right now I would even speculate are involved in some money laundering schemes. When my eyeballing estimate comes to 50x cost/msrp margins, I know things are not right and developing and selling a product is not a priority. Not sure this is the case for American companies, but for some European, and especially South and Eastern European, I can bet on that.Are you sure you're not mixing up Barclay and Marantz?
