ASR list of known class D home audio amplifiers.

@Doodski You're going to have to rewrite all the power specs as the companies re-rate according to the FTC requirements.

O MY!... Sigh*... maybe I'll just erase them and leave them blank...lol.

I wouldn't rewrite the existing power specs, just add the FTC ones as they come in. Stick a note in the header about the difference between FTC spec watts and manufacturers' claims so people can see the difference.

There has to be an easier way of maintaining lists like this than using the forum editor.

I agree. What I am doing is copy-pasting to a <.txt> file to strip HTML off the text and any formatting. I make data on the <.txt> file and then copy paste it to the ASR page.

I've experimented with tables here - copy/paste from a spreadsheet seems viable. I'm also wondering about templated generation of BBCode from a more manageable data source like csv or json that could be kept somewhere like github. Probably a conversation to be taken to that thread?

You are into things I have not experienced yet nor do I know about that stuff.

Thank you. The list is a work in progress and I will be taking it up in the fall. With the new neighbor and friend that I have, helping other neighbors with their electronics stuff and summertime I've been short on time for composing this class D amps extensive list.

It'd be good to have a summary of each chip's know characteristics, like a reasonable guess at the power level, even if it's just relative to each other.

I want something equivalent to a 55w receiver, maybe up to like 90w at 8ohm Old School units. I need to keep going back thru the specs and tests of D class amps I already have here, and comparing them on the fly. I have a few old receivers that are rated at 35 to 55w and they are punchy.

Here's this...

There's lots of effort still required to get the simplest of information listed in this thread. I have a extensive list of class D amps that is yet to be added to the list and then the FTC regulations that came into being months ago affect the present list that I made that now needs to be revamped and updated to the new FTC ratings. Lots of work to be done. I prefer multiple features listed for each amp and yet I am limited line by line and keeping the information easily read so I try to keep each model to using a single line on the thread. As it sits now I use notepad to paste in web page details and strip any HTML out of the copy paste process and then I format the font, color and size etc and the effort adds up to a bunch of days of effort. It's coming... I was thinking about it this afternoon as I ate lunch and realize I should get cracking on this again.

I guess I mean in regards mostly to the mini amps which sell like hotcakes. Just to put them in order would be really helpful. Once I have a unit picked out, I end up having doubts if it's the right or best one for my needs.

We should start from the bottom up

Ahhhh... Categorically arrange the small IC type mini class D amps. I could arrange something like that for them.

He said "We". Maybe you should accept his offer....?

 

[Count Dacula]

People who have been in the game for a while probably know the list of suspects better than I do. I actually have a few in mind, but don't want to cock it up either.

MA12070 vs TPA3255​

"specs" are 300W *2 under@4 ohm and 80W*2(4Ω), 40W*2(8Ω)

What did Amir's tests say..?

BT20A equipped with two Texas Instruments TPA3116 chips, delivering an impressive 100W RMS per channel at 4 ohms, 20 Hz - 20 kHz, 0.04% THD, the amplifier produces powerful and clear HiFi sound. It allows fine-tuning of bass and treble to suit your preferences and can drive speakers up to 280 watts at 8 ohms or 320 watts at 4 ohms.

I'll add that Fosi BT20A when I get moving on the list again.

No Bel Canto in that list. That have a couple nice ones

IIRC it was decided not to include pro amps in this list, which would exclude all but the MX-D1.

Those power specs are almost as slippery as the ones we see for cheap chip amps. No distortion level is given, and duration is very short:

1kHz, Non-clip, 20msec Burst, All channels driven
