The USB slot works fine with external storage, having used it with a 64gb pendrive with FLAC files does a pretty good job( not sure if there's a bottle neck here while using FLAC).Have used an external hard drive without any hiccups and it sounds ok. However it sounds best using Aux.Oddly the USB input is type A. At first I thought this was for external storage but manual talks about using this with a computer. I didn't have a type A to type A cable so didn't test this and stuck with Aux analog input.
The heart of the unit is Infineon MA12070 class D amplifier.
Will be upgrading the caps in the near future under guidance of FM @dr_mick51 who was more than kind to spare time from his busy schedule & helped me with directions to mod along with part numbers & pics.( Mod delayed due to scarcity of Nichicon UCQ & UUQ parts). I thoroughly enjoy this tiny amp more than the Rotel & Technics amps that i have & think it's great VFM & m sure the mods will enhance its capacity further. The best part is that it stays cool even after using it continuously for 5-6 hrs at 70% volume.
