Yes, you can get more power with a higher power supply. I am not sure what you mean by “dedicated switching PS” as almost all of the TPA3255 amps use external switching power bricks. That one seems relatively expensive.I can't help but think that the power supply is an obvious avenue for upgrade for these evolving tpa3255 amps. Has anyone looked into a dedicated switching ps like this one? Tia
Fosi V3
In the test of the Fosi V3, the Fosi 32 V power supply was able to achieve 62 watts x 2 while the 48 V supply reached 141 watts x 2 with the same 4 ohm load. Power is the major benefit - the TPA3255 has pretty good power supply noise rejection and these switching PSUs seem to generally have acceptable regulation in the audible band.
