I wish Topping make a stereo amplifer.
You get a lot more of virtually anything for the same money in the US, especially in the less-visited Heartland. Even stuff that is made in the EU is often cheaper here, like wine, cheese, even my breakfast:As far as I know Creek rised its prises as well, seems to me EU market is hugely uncompetitive for audio manufacturing.
Please get this one measured. I want to know its SINAD.
This is a stereo amplifierI wish Topping make a stereo amplifer.
Are you serious!I wish Topping make a stereo amplifer.
That's the limits of used power chips (max 26V DC).The wattage is quite low. Or can more powerful adapter be used for a boost ?
It just means that technology in speaker amplification hasnt progressed that much so a 4 grand amp can be made for the same specs in 2021 for $150. In fact they might cost as much if not more. This isnt the fault of a single manufacturer like Topping but perhaps the industry as a whole.
This amplifier is absolutely tiny. Can fit 2-3 of these + adapters in one of my NC400's. So that's 4-6 channels vs 1 single channel in terms of space.50W is really little for an amplifier, yet along a Class D amplifier.
I wish the design (or future design) were based on TPA3255 with a proper passive cooling solution, allowing much more clean power for little money.
I believe SMSL omits the output filter.
Also, apparently the Infineon chip used in this amp (along with the SMSL SA300, DA-9 and AO200, among others) can be used without an output filter for very short speaker cable runs. I believe SMSL omits the output filter.
Also, in reply to "I hope not. This would be easily detectable by oscilloscope at the amplifier output." regarding the lack of an output filter on SMSL Merus-based products, Archimago reported that the SA300 output was indeed unfiltered.When I first got my SA300 I used a short run, under 18", and it kept sending the amp into protection mode. At the time I was rebuilding some crossovers and just using it so I didn't have to drag towers back to my AVR. I thought I had a short and I looked it over couldn't find it. The same thing happened with the other speaker. Finally realized the cable was the issue so I tried a new longer run, worked fine until I turned it up a little then the same problem. It wasn't until I got to about 3 feet that it stopped doing that. Not sure if it's related to the output filter just wanted to share the story. Same thing happened with the speakers the SA300 was intended for, had to do an annoyingly long run when the amp was right next to the speaker. I'm not sure if the Sabaj A20a I replaced the SA300 with has the same problem since I've never tried it with a short run.

Well, unless you have an AV prepro ($$$$ and questionable performance), a miniDSP 2X4 ("OK" performance according to an early review by Amir) or one of the very few subs with high-pass outputs (questionable performance), a powered sub won't take some of the load. 2.1 bass management solutions are very limited.The use or not of a powered sub to take some of the load
I just ordered one for my desktop. Mostly because there is little room for a Bryston.
Welcome to asr. To answer your question , no we only listen to oscilloscopes and analyzers round here.Newbie here, but were there any listening impressions based on this amp?
