It’s almost 100 metres to the weeds at the end of my street. BTR1K got 75% of the way before its signal went soft, and 90% of the way before it completely broke up. That’s as good as the Radsone EarStudio ES100 was with Firmware 1,4, and better than every other Bluetooth DAC I’ve tried, price be damned.

Disclaimer: Radsone sent me the ES100 for the purposes of this article, a review, and some YouTube coverage. It decodes just about every wireless format out there, more than breaks the 16-bit ceiling. Moreover, it spits balanced audio from its 2,5mm jack. It goes for 99$ USD on Amazon.

As you know, I love the BTR1 and uBTR, but the BTR3 is a swing and a miss. Great measurements, yes, but physical interface/orientation problems and poor wireless signal catching make the BTR3 practically rubbish to use.

I get over 7 hours on a single charge, and notice very little hiss at all. It shows a certain amount of frequency oscillation, and moderate levels of jitter. Next to Astell&Kern's more expensive XB10, both are minimal. The BTR1 sounds, and measures, good.
