I’m curious if anyone has some experience with a class-d amp and full range speakers. Right now I have a gainclone driving some 8in audio nirvana speakers but I’d like to try out a class d amp.
Will the 20 watt amp from Adafruit (using max9744) or the Charlize from diyParadise (ta2020) be enough? Or should I plan on something bigger?

I just switched out one of my tube amps to an older Topping 2020A Tripath to drive my SEAS full ranger 8 inch speakers .
There is not a lot of low end there but so far has a very pleasing sound .
Really nice fatigue free midrange and high end .
Last month I purchased a Charlize 2 from a forum member and after getting it in a case I will change to that amp .
Today I am changing the filter circuits' resistor value on the SEAS from 7R back to the original 15R value specified by SEAS since changing to Class D.

Hello jay,
with my Tang Band fullrange, I'm using the 3e-audio TPA3251 amp. The sound is really excellent.
I also have a 2x400w Sure amp (T-amp). The sound is good too. But I prefer new TPAs.

I fed some el cheapo 3 and 4inch full rangers (Taobao sourced) from a TDA8932 amp for a while. I sold them off as I didn't like what they did to the HF, but the amp I still am using, albeit now with 2-ways. I still recommend TDA8932 (with extra caps on its analog rail) so long as your speakers are 8ohm or higher. TPA3251 and TPA3220 are also good amps when similarly modded.
What's a good source for a TDA8932 board? I see them on Amazon as low as $2.50 but most are around $7-8 (similar range on eBay)... are these all basically the same? If so I'm going to try a couple of these out as well.
I've only played with one TDA8932 commercial board, and its this one (no longer shows up on Taobao) : 35W High Power Mini HiFi Mono Digital Amplifier Board Ultra Low Power TDA2030A-in Integrated Circuits from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
Pretty much all the other boards I've seen look to be the one @chermann has shown.
