Hi amigos,
Seems that the new version of the finished 3E Audio TPA3255 is now provided with DIP8 socket to update OP amps, good new )
Amplifier will be sold with 2 PSU options :
44V for 8ohn
37V for 4ohm

Guys )
Open your eyes... look at the Heatsink, this is the 3E Audio design )
The board uses 3E Audio SMPS PSU + same spec as their TPA3255 Mono / stéréo boards.

PS : but not sure this is the final design.... I spoke with 3E Audio last week and the board would came with OPA 5532

the workmanship is remarkable!

I see a 2 prong power chord entering a metal case. The worst case scenario in terms of electrical safety. Like so many of these chinese designs, no CE-declaration or CE-marking and electrical safety is something for sissies. Building an audio amp takes more than optimizing audio aspects. 😡
There are two types of 3e audio SY-DAP2002 available: SY-DAP2002 -4ohm / 37V and SY-DAP2002 -8ohm / 44V.
Is the reason for this divided into two types because it is necessary to lower the voltage due to insufficient power supply capacity with a 4 ohm load?

I believe the lower input voltage for the 4ohm version will be to lower the heat generated by the amplifier chip with low impedance speakers and high psu voltage.
However I run my 3e 2channel into nominal 4ohm speakers and run at 51v. No problems so far. Been powered up 24/7 for months

How is the sound?
Is it the same as the board?
