Crazy to think how far Class D has come in 10 years.
There's a thread at diyaudio on the ti eval units.Looks interesting, but the 3255's are oos
Out of stock at TI, But 3e-audio have them in stock. They cost $25 more than the TI's discounted boards, but I think they look nicer and they a little measure better than the TI. Very nice boards, real solid feel to them.
Curious what op amps 3e is using? In the ti board, it uses op amps to generate a balanced signal to the amp chip from a single ended input.Since my dac is single ended, would be using the op amp.Randy
The TI eval board for the 3255 allows for a single channel output of around 600A. I thought it could make a good sub amp. The 3e-audio board doesn't seem to have that ability.

600A (amps) would be enough to completely melt the driver and anything in it's vicinity! 600W is the max 2Ω mono output. Of course, that figure is with 10% THD+N, which is fairly high even for a subwoofer application, and 480W is the mono 2Ω output at 1% THD+N.wushuliu, I see you're using an SMPS with your TI module. I've noticed that with manufactured Class D amps including the Class D manufacturers on this forum, the field seems to be split between SMPS and Linear supplies, and the linear supplied amps actually seem to be more prevalent among the smaller boutique manufacturers.I'm sure you've experimented quite a bit with both and have you come to a definitive preference or has it varied with each Class D module?Steve
Hi wushului, How would rate this amplifier compared to a Classdaudio SDS254?I see that 3eaudio also have a SMPS.
Are these available in a ready made amp? I love DIY audio and enjoy building, but have almost zero free time these days......well a few hours to do crap like post on forums, but not enough to source component and build an amp I have a lepai 2020A powering my Merlin monitors in my computer monitor setup. Clearly an amp upgrade would help. Lepai is a decent dirt cheap little amp and I'm impressed it can even power these speakers. but it makes me want more. (decided upgraded PS not worth time or money)
So are all the connectors provided w/ the amp board & power supply? (3e audio website & their ebay listings do not specify or show separate accessories).
A full set of connectors and wire tails are supplied with the amplifier board. With the power supply comes a longer umbilical than shown, and an AC connector with wire tails.There is a large variety of chassis/enclosures available from either ebay or AliExpress (https://www.aliexpress.com/af/amplifier-chassis.html?SearchText=amplifier+chassis<ype=wholesale&d=y&tc=main&blanktest=0&initiative_id=SB_20170927034752&origin=n&catId=0&isViewCP=y)
