Hi Just now saw the thread re TP3255 amps.
I have an Aiyima A07 that I will be using to power a pair of 4 ohm planar tweeters in a Triamplified system above 3kHz.
Concerned about the Aiyima amplifier's lifespan (I've read that the caps don't like heat), I have purchased a 24vdc/5a power brick to lower the operating voltage from the stock 32volts.
Anyone here have experience using it at 24v and how does the amp perform, objectively & sound wise?

i dont think sound 3khz and above need much power and generate heat so much...... but in my opinion, class D is better place in woofer section if you use triamp configuration. Class D will generate distortion higher in 4khz and above,have load depedency if they not PFFB, and will not generate hum if you using SMPS not linier PSU
Distortion of TPA3255 even without PFFB is quite low compared to many linear amps. It is also one of the quietest amps when used with a good SMPS. I measure less than 1uV rms noise amplitude from 20Hz to 20kHz. I personally like the sound quality a little better without PFFB.
24v supply with BTL config is 48vpp. That is 17Vrms or 36w into 8ohm load or 72w into 4ohm load. It’s enough for most domestic smaller rooms and moderately sensitive speakers.
