Are there powerful class-D amps without audible noise?
I want an affordable powerful class-D amp without audible noise.
Because I'm going to listen in front of a desk, reducing noise is important.
I looked into TDA7498E because it is powerful.
But, it seems to be affected by noise issue.
Reportedly, some TDA7498E amps produce hiss at 13~14khz which many humans may not be able to hear.
Do you know any affordable powerful class-D amp without audible noise?

Think it depends on your speakers, if they are full blown horn loaded + 100db you might hear a faint hiss in tweeter
My speakers are Eltax Monitor 1 which has sensitivity of 87dB and impedance of 4~8 ohm.
Currently, I'm considering Nobsound dual TPA3116, TDA7498E amps, and chinese no-name TPA3255 amps.
No, there is no case for me because I'm going to order a chinese TPA3251 amp.

At stock it sort of get's a little intrusive in the highs at high volume (loud)
Sound like my amp is enhanced in the highs and lows, using a 24v,6a power adapter,supply and have read in a big class d thread that the amp starts to get less bright when using a bigger power adapter,power supply, let's just say 36v to keep it simple (max my amp normally can handle) and 19 volt stock or minimum you should use for good sound and power
Mabye the gain is a bit high an overloads, so i used my rothwell 10db attenuators, now the highs sound better and i can use all of the range of the volume before it's loud, some songs are not played at max volume even when i have the volumeknob at max.
I don't here any distortion unless i play really loud without using the attenuators and it's not because im trying to exceed my amps limited

I've used TPA3251 and TPA3255 amplifiers. The chinese TPA3251 amplifier was configured with high input gain, so it was difficult to control volume. The chinese TPA3255 amplifier was configured with low input gain, so I could control volume with ease.
TPA3251 and TPA3255 are fine if they are configured with low input gain.
I'm looking forward to allo's TPA3255 amplifier which will be released next year.
