I'm afraid that remains to be discovered.So what is the pick budget mini amplifier that performs greater than expected? Doesn't have to be mini, just cheap, pound for pound as we say over here Plenty of power would be a bonus
hmm, 5 watts I cant live with unfortunately. There must be something surely, how about a S..M.S.L 98e ? lots of power but I suspect the same sort of thing as whats on offer in the initial test here.I'm afraid that remains to be discovered.
Or if you need just 5W, a Topping A90?
It isn't really a consumer product, more like an audio hobbyist item, but the guys at Allo have a cheap, mostly plug and play amp:

Allo's gear generally seems to be pretty solid when measured here in ASR (looking forward to seeing if Amir will be able to review the new Revolution DAC from Allo). By reputation, the Allo Volt is clean and very resolving. I have a Volt+D and it sounds extremely clean and detailed to me (subjectively) but I don't have instrumentation to measure things.
I'm attracted to ABGN Hot-Tpa3255 because it is more powerful and uses a more recent amp chipset. What kinds of power supply do you recommend for this? The seller recommends 30V 6A although I may want more power to create headroom for Eltax Monitor 1.
most manufacturers would have implemented the "better" one, in most cases, due to the minimal financial outlay across the Op Amp portfolio available.
Having said that you'll _probably_ get away without lasting damage to the amp,
IIRC TI use the NE5532 in their eval board to get full datasheet performance out of the power amp chip. The FX502SPRO falls short of that performance, probably due to cost cutting in PSU caps and output inductors as well as PCB layout. While this is understandable given the price, it also means the opamp isn't likely to be the limiting factor - unless they've gone for an off-brand 5532 too.I've ended up with two OPA228Ps because they were flagged (somewhere, by someone) as an appropriate replacement for some other op amp that was likewise flagged (somewhere else, by someone else.....) as an appropriate replacement for the NE5532 that comes in the FX502SPRO. If I remember correctly.
Hi, welcome to ASR. I too had no problems with my FX502S Pro, I sold it about a year ago. As a new Fosi V3 owner I can tell you there are NO problems with lack of clean volume. The V3 uses a different taper on its volume control. Compared to the FX502S, you have to turn the knob up a lot higher to reach the same volume. That is on purpose, so that you have more control. The volume goes up evenly the whole 360 degrees. Please check out Amir's test of the amp here. Once you get to 100% it will put out a LOT more clean power than the FX502s.I have been using the FX502Spro amplifier since 2019.....
I'm really looking forward to seeing an upgraded version of the TPA 3250 with noticeable audible improvements. However, I've come across quite a few negative reviews about the Fosi Audio V3. At the same time, I'm not sure if those negative opinions about the lack of clean volume in both amplifiers really apply to their use at home with moderate volume levels.
FX-AUDIO FX502S is a product from the early days of class D amplifier products.How good is the FX-AUDIO FX502S PRO BT ? (couldn't find anything about it on asr and youtube)
Does it also have the roll of in the highs ?
FX-AUDIO FX502S PRO BT Amplifier
The FX-Audio FX502S Pro BT is a compact Class D integrated amplifier, using a TPA3250 amplifier chip to deliver up to 80W into 4Ω with high efficiency. It offers precise, dynamic sound reproduction and represents excellent value for money.www.audiophonics.fr
