Hi all, I've currently got a FiiO E17 that I use with my Galaxy S8 via USB with my RHA T10i IEMs (I know their sound profile isn't to everyone's taste but i find them very pleasant to listen to, way preferable to my Triple.Fi10s). I'm a little fed up of the extra wires and bulk that this DAC/Amp combo introduces but the S8 cannot remotely drive these IEMs properly, despite only being 16ohm. Has anyone here used an E17 and also ampls such as the BTR1? How do they compare? Will the BTR1 be capable of driving these IEMs as well as the e17 can or will I need to look at the Astell and Kern XB10? For reference, whilst the sound quality is much improved from my iPad air 2 compared to the Samsung, it's still a long way off the quality of the e17 so if the BTR1 is "only" as good as an iphone or S7 then it's going to fall way short of my expectations. These two seem like the only options that look suitable that I've seen so far. Thanks in advance! Kind regards, Tom.
