### ⭐⭐⭐⭐⭐ Amazing Amps for the price
*by L***O on December 7, 2025*

Insanely good little mini amps, Very clean sounding - some speakers may have audible hiss if gain is up too high if they are very sensitive but if you are feeding strong voltage over RCAs turning gain down easily tames it. These can get a bit warm if you push them too hard but testing at high volumes for hours on my setup only left them slightly warm to the touch so I don't think they are as bad as other mini Class D amps and if you have heat issues you are probably doing something wrong.
