Topping DX3 Pro+ headphones amp, not given it a proper running yet to determine if it's actually worth the extra over my already good headphone output on the main amp (MX3s), so might still return it to Amazon if it turns out the extra gains don't warrant the extra cost over what I already have. Will know by this evening
Also saw some Eneloop Lite batteries for the remote so got a pair of those, didn't know Lite versions existed and bought without checking capacity (they are min 550mAh), and now realise I already had better EBL 1100mAh ones which are also low discharge. Ah well the 550s will go in some basic remote I guess lol.
