I voted fine given estimated use case of desktop speakers and sub. A pocket wonder for just $125 Aaaaand it has automatic high pass filter for subs. My amp (Audiophonics S400ET) cost about 10x as much.
I've got one of those too, and it is 10 times more powerful with 10 times less distortion. I don't see the reason or logic behind our comparison. Please explain.
 
The amp has a proper high pass filter for the mains. Its frequency is a bit high at 90 Hz.
I believe they chose this value because the speakers they sell (CG3M) have a frequency response of 90-20,000 Hz ± 3dB.
 
How can this be recommended when it is broken in multiple ways? You can buy better amps from Fosi for less money that actually work... This just seems like junk they didn't even test themselves.
 
That JieLi BT chip is possibly the culprit for bad USB performance.
I didn't think for the life of me that such a chip, usually seen on cheap-as-chips Chinese DIY boards, would be in $100+ products.
 
I have a soft spot for RSL as my very first good speakers were two-way RSLs, from their big store on Van Nuys Blvd. in the San Fernando Valley in LA. Very good sound from their house brand which I bought (thanks, parents) in 1974 or thereabouts. Kind of amazing the company is still around after all these years.

But I wouldn't buy this amp, would much rather have an Aiyima or Fosi amp paired with the Fosi P4 preamp, for just a bit more $.
 
Oof, was hoping the results would be better, will be putting this little guy up for sale once it returns home. Not sure if it's discontinued or not, haven't seen it in stock at RSL since the tariff changes went into effect.
lol i think youre the same person that recommend the d3v to me a few weeks ago on reddit and its just funny i find you on here on another forum where i was looking for an amp! so wanted to ask what desktop speakers you run and how you like it. i have a pair of philharmonic true mini and a rsl 10e sub and i was planning on using it on my desk for the most part but may move it to my tv for a 2.1 setup and add a wiim ultra down the road. Would the rsl hold up well for the desktop use and maybe the tv use down the road?
still have the d3v but ended up getting philharmonic true mini and rsl 10e sub as well so trying to figure out what to drive them with

Ha yep thats me. In the end, if your setup sounds good to you then enjoy it. Tbh if I did a blind test I probably wouldn't be able to tell the difference between the RSL and a better amp. But if I can buy an amp for like $20 more and it's been proven by Amir to be significantly better, I'll probably pay that difference. And there are many here who will pay much more. There are definitely diminishing returns but geeking out on this stuff has become a hobby for me.
