Hi everyone, I'm new here and I see people who seem to know what you're talking about, which is why I registered.

Amir has measured a new TPA3255 Amplifier which seems very good, and the price is extremely reasonable.

Fosi Audio BT20A Pro Amplifier Review

This is a review and detailed measurements of the Fosi Audio BT20A stereo class D amplifier based on TI TPA3255 IC. It was sent to me by the company and costs US $99.99 with 32 volt power supply. Despite its low cost, the case gives a feeling of quality. I am not usually fan of tone controls in...

I am looking for a finished MONO full range TPA3255 that takes DC input power to use with my own Mean Well adjustable PSUs.

Must be high accuracy SQ, and lots of SPL power into 2/4/8ohm ideally close to doubling RMS watts as resistance is halved.

Thanks in advance

I don't think you will find a finished amplifier that meets these requirements and has connections for an outboard PS.

If you want such an amplifier I suggest that you build the amp from a finished module, and there are two options (that I know of):

SylphAudio

TPA32xx with PFFB | 3e Audio

www.3e-audio.com www.3e-audio.com
The mono amp modules double power into half the load as you mention.

The first company does limited runs and when each sells out, then he makes a new and different board. The second company just sold out of both the mono and stereo products but is producing more and these should be available in 2-3 weeks. Both are reputable small manufacturers.

In addition to the amp module, puchase a chassis and then install everything yourself. For example, I recently purchased a few different chassis here, and had them custom machine the rear panels to fit the connectors I plan to use. I also use Meanwell supplies and these will go inside the chassis:

Hey guys! Does it matter if the TPA 3255 chip is powered by a SMPS or a Linear one? Is one better than the other?

In this case the SMPS is the better choice. Any power supply noise is moved up into the hundreds of kilo cycles so you can't hear it and the SMPS is very efficient on electricity use and cool running. :D
