Impressions: SMSL PA200 GAN FET Class-D Power Amp

This isn't an experiential centered site. A little situational awareness and understanding your audience goes a long way. The vast majority of people are here for the science based objective information, not so much the "listener impressions" many audio sites focus on. It should be no surprise at all that people here question subjective statements. Subjectivists would do well to find a site more attuned to their belief that 3rd party subjective opinions have merit as most here find them a waste of bandwidth.

I believe the "define respectful" comment was done tongue in cheek...

The elaborate response to the tongue in cheeck comment tells otherwise but ok, nothing to see here, I get it.

It could be suggested that subjective impressions becomes objective impression, when there is a repeatable conclusion and indicates that investigation is required/needed to establish why this is so.... that is reasonable, isn't it?

Sure, when there is a *verified* repeatable conclusion (and obvious explanations such as expectation/confirmation bias have been ruled out).

...obtained with basic ears-only controls.

Now you have a definition.... Apologys, if you do not find it 'Helpful' and 'Respectful'

It will be helpful that we get back to 'Impressions: SMSL PA200 GAN FET Class-D Power Amp', as suggested, and I ask and suggest that if you post your impressions of the PA200, as the thread suggests, would be helpful.... this is reasonable, isn't it?

Thank you, yes, but you left out this part....

Thank you, but you need to ask yourself, was your intent/desire to be with or at (the intended individual/OP)? It can be suggested that 'with' is always ok (friend) but 'at' is never ok (enemy).... that is reasonable, isn't it?

Edit: Note that your posts are suggesting that people should not purchase the PA200, as per your often questioning/doubts, yet being objective, you have not provided even one objective measurement that suggests they should not.... this is a reasonable analogy/observation, isn't it? If you do have objective measurements then you are welcome to post them but please indicate that you consider them to be accurate or not accurate.... this is reasonable, isn't it?

Subjective impressions are reasonable - on a typical audiophile belief bubble site. Here, not so much.

If there's controls. Otherwise it's storytelling nonsense which doesn't belong in serious discussions.

Not here.

It isn't informative. How about soliciting controlled subjective test results?

Than you, yes, that needs to established not assumed.... doesn't it?

Thank you, definitely not insisting, but would you be willing to do a controlled subjective test, for the PA200 then post the results? If you do, then you know that you are welcome to post them but please indicate that you consider them to be accurate or not accurate.... this is reasonable, isn't it?

A former colleague, Dr, John Glaser now works for EPC (Electronic Power Conversion). They are a leading producer of GaN devices and products. EPC has very nice videos for their technology, which explain the benefits of the higher switching speeds and much smaller dead times of GaN FET technology. While working at developing power electronic projects at GE Global Research, we were always pushing to reduce device dead times to reduce switching losses and improve performance. With GaN this becomes much easier. Here’s a great video that explains the benefits of the technology. It’s a little long but interesting and I apologize, if I posted this previously.

Wondering if I should upgrade my pair of Fosi V3 monos with dedicated 10A PSU to a pair of SMSL PA200 for my 38 years B&W DM3000 power sucking speakers or just recap the speakers themselves.

With amps like those, you’ll get a lot more out of any improvement you can make with the speakers than you will from a change in amps.

ah, time to recap and find a 6mH iron inductor

SMSL PA200 does not come with PFFB, I have checked with Taobao official store and they checked with their technical staff.

That's not what the manufacturer told me...

It it could be suggested, why wonder? You could simply purchase the SMSL PA200, to compare to the Fosi V3, with your (unchanged) speakers, can't you? This is an objective approach, isn't it? If you do not like the PA200 then you can return it for a refund and post your like or dislike impressions in this thread, can't you?

A point to consider, though.... @EddNog, did you notice a QC/Test sticker with your units (an objective process, isn't it? usually on rear or bottom panel) or QC/Test indications on the SMSL website)? If no, then until clarifyed, the purchaser is the QC/Tester, aren't they? As such, @Loba, if you do purchase an SMSL PA200 then you should test it (perhaps playing music through it for 10-12hrs/day) to test its robustness and evaluate it at the same time, shouldn't you?

If you like it, enough, then you will probably keep it but regardless and after, you can still recap the speaker crossovers, can't you?.... enjoy :=)

edit: if you do purchase a PA200, keep it, and post your impressions in this thread then after you recap the speaker crossovers then you can edit your original/impressions post and add your impressions of the PA200 with the recaped speaker crossovers, can't you? If others ask then you can direct them to your post.... enjoy :=)
