15 watts stereo class T amplifier TA2024 sound test and review

TA 2024 is low cost15 watts class T amplifier (I got it from eBay for 4.94$ free shipping). The amplifier board uses MKP film as input capacitor that hard to find in cheap board amplifier from eBay. The amplifier sound very clean and details and loud with high sensitivity loudspeaker (89 dB or better), bass not big but control well. However, high frequencies tend to roll off a little bit but still good. The TAta2024 amp is good with Jazz, pop, guitar solo, saxophone, and smooth jazz in my opinion. If you use switching power supply you need to add at least 2200 uf capacitor parallel to the power supply for best performance. TA 2024 specification: Class-T architecture  Single Supply Operation  “Audiophile” Quality Sound  0.04% THD+N @ 9W, 4Ω  0.18% IHF-IM @ 1W, 4Ω  11W @ 4Ω, 0.1% THD+N  6W @ 8Ω, 0.1% THD+N  15W @ 4Ω, 10% THD+N  10W @ 8Ω, 10% THD+N  High Efficiency  81% @ 15W, 4Ω  88% @ 10W, 8Ω  Dynamic Range = 102 dB  Mute and Sleep inputs  Turn-on & tu

10 watts 8 ohms class d amplifier pam8610 sound test

Pam8610 IC is 10 watts @ 8 ohms (15 watts @ 4 ohms small heat sink require) stereo class d amplifier with very high efficiency over 90% and the amplifier works well without any heat sink at full power!!! . The amplifier board is very low cost ( around 1 $) but deliver 10 watts @ 8 ohms power from 13 volts power supply. As you can see in my video that the amp board require only one 100 uf electrolytic capacitor for supply decoupling to eliminate hum from switching power supply(some ic amplifier require 1000 uf to eliminate hum from the power supply). Sound testing: The amplifier sound good with good bass respond  good bass impact and well control (kick bass very good). High frequency clean, impact well and flat but lack transparent. Singer vocal is clean but not transparent. The sound stage is wide but space between instrument not precise. pam 8610 amp board is the quiet amp with very less hiss noise (5 cm away from tweeter to my ear :) which is not a big problem at all and the
