I like the price.
I hope that rack mounts could be deattached in the final product.

No. There are footers (you can see one on the left) that are screwed to the case. The tape is for the insulations shroud as mentioned.Is this really double sided tape to fixate the power supply?
WTF are "digital amps" and what are their "usual issues?"all the usual issues that digital amps have
I'll let you know. Having worked in broadcasting for decades I've long neglected turning off audio gear at home and I'm about to buy 3 of these.The price is in the Beheringer range. So with mounting ears like that the next question is how long does it last when running 24-hours a day.
I understand your point, but DIY solutions are always cheaper. This is a ready to use product with nice finish, screen, and remote control. So I think it's justifies it's price.I think the point a lot of us are making is that there are ~140W@8R TPA3255 implementations for less money, and no performance losses that would actually be audible.
For example anyone with the most basic of DIY skills could assemble a 3E PFFB TPA3255 amp, and something like a Meanwell SE-450-48, and have a -104 SINAD @5W, 130/230w capable tiny desktop amplifier, for <$200.
Shame they do not sell pre-built as this would be the de-facto amp recommendation I beleive. But putting it into a box with a SMPS is a trivial 1hr job that I think even my mother could do after watching one soldering tutorial on YouTube.

DIY solutions aren't really for everyone to do either. It's easier to assemble a PC from parts but even with that a lot of people would struggle.I understand your point, but DIY solutions are always cheaper.

an even someone who does - many will not do a clean/proper job with cable managementDIY solutions aren't really for everyone to do either. It's easier to assemble a PC from parts but even with that a lot of people would struggle.
A volume bypass would be nice too, maybe in a future firmware upgrade.These seem like a good option for my active 3 ways to sit on top of an xli800. I wish there more options with digital volume controls though. Despite my best efforts to dial in amp gains, one stray paw from a cat is enough to knock some of my knobs out of balance and then I've gotta get the measurement mic out again.
Only place I found it is on taobao, I hope it will quickly appear on Audiophonics!Sorry if this has been covered - I jumped from page 4 of comments to here. Where might this be sold? Nothing comes up online.
You're right Amir. I started my HiFi "journey" with a Sansui AU 719 and TU 719 and AR 14 speakers. The Sansui set looked very "pro" with its, detachable (!), rackmounts. The set played for over 20 years. I bougt the set in 1980.Folks, this is NOT a pro amp. It is a pro looking amp for home use. No pro amp needs a remote control or selectable inputs. This is a very high function and high performance amplifier put in a rack mount case I suspect to save cost. Rack mount cases were all the rage in 1980s and was a sign of equipment being "high-end!" Here is my carver receiver of the era:
On power, you need to focus on 4 ohm rating because that is where the demand is from vast number of speakers.
On reactive loads, the amp I am sure handles them. It is just that my testing pushes the amplifier into clipping and then backs off. When the amp shuts down, the script that runs through all the variations then produces garbage. This is why I didn't run it, not because the amp can't handle reactive loads.
Point taken. But there are pro situations where budgets are very tight and performance like this TP's would be welcomed. (Actually the remote can be handy in commercial installations although it might get lost.)Folks, this is NOT a pro amp. It is a pro looking amp for home use.

Interested to hear about your experience with them in the future. I’m also a prime use case for this as I have an active large 3 way prototype waiting for the right combo of amps for the mids and tweeters on a more permanent basis. However, I’m not willing to jump in with Topping from the get go. I’ll wait about 8 months to see about reliability. By that time I’ll either pass or go to order and find out it’s not made anymore!I'll let you know. Having worked in broadcasting for decades I've long neglected turning off audio gear at home and I'm about to buy 3 of these.
To your point, there is a more sensible thread that the designer started:After going thru 13 pages of comments, I wonder at the collective ability of a group forum members to understand this is a technical review of a product. Does it meet its manufactured specifications or not.
The product was supplied by the manufacturer and to the their credit a forum member John Wang helps answer valid question from other forum members.
Why on earth do we question the power rating, box size and price., oh and its designated Pro application!.
Its what it is, its specifications and design is based on the manufacturers belief there is a market for it.
If its not for you move on.
Could we possibly start a parallel thread on every review titled "Opinion Page Review".
That way genuine technical questions can be kept to the review thread and all the other queries and suggestions for improvement etc can go on a parallel thread.
That way a reader who wants only facts and answer to technical specifications not included in the review can save time, and if they want "opinion from the experts" they have another separate space to go to.
Also it may create a better professional and courteous discussions where we dont really need to barrage Amir and other reviewers who are doing this as a free benefit to the audio community.
Just sayin
Don't you think there's interest or validity in posting along the lines: interesting product but not suitable for my application _x_ because of _y_?Why on earth do we question the power rating, box size and price., oh and its designated Pro application!.

You forgot a lot: Remote control, amp box/chassis, all contacts and so on. That is to build something similar to TP RA3 that is.For example anyone with the most basic of DIY skills could assemble a 3E PFFB TPA3255 amp, and something like a Meanwell SE-450-48, and have a -104 SINAD @5W, 130/230w capable tiny desktop amplifier, for <$200.
