I drive 2 Bose 301s with this amp in my home gym and the sound is superb, more than loud enough with no clipping or muddiness. I wish I had a use for another one.

Works well. Compact & efficient
I wanted a small amplifier to use with a tablet computer and a couple of speakers in the kitchen. Space is at a premium. Its footprint is smaller than the tablet, and it scarcely gets warm at all. Sounds good! Im happy.

More information on the TDA7498
This is a very interesting article if you are considering buying one of these as I am. https://trevormarshall.com/class-d-tutorial/
The hardware is very similar to that in the article.

Great little amplifier
The subwoofer channel on it comes through really clear with little clipping at high volumes when you have the settings correct. I powered it with 24v supply

Just so so
Ive used many TDA7498 amp boards in projects in the past so I thought Id give this one a chance in my next powered speaker project. Ive tested this on many different speaker systems and types and find inferior sound. Little bass, muddy mids...and total lack of wattage output..even when gain set at highest. May not even be a 7498 but a Chinese one-off. Poor components make a second rate amplifier.
