Brooko's Test Tracks

So I can keep them in one place - and refer to a list (by link) with my reviews, I've compiled a list of the test tracks I use.  Some are definitely for a set purpose (eg Amber Rubarth's Binaural "Tundra" for imaging and sound-stage), whilst others are simply tracks I know well - and use so that I can cross check headphones for a wide range of suitability across genres.

Though iTunes wiped out the need for competition when it was introduced, it has become a huge, multimedia and store program, leaving many people wanting something simpler.  For a while, that was Play and one or two others, but then Amarra came on the scene. Offering higher-quality playback, it has become famous among audiophiles, alongside its biggest competitor, Pure Vinyl (and now Pure Music).  As those two have fought... read more

Ibasso DX50 FAQ

The Ibasso DX50 is a $239 baby brother to the $830 DX100. Smaller, less powerful, with less onboard storage (8gb vs. 64gb) and using a Wolfson WM8740 24Bit DAC Chip opposed to the ESS Sabre 9018 desktop-class DAC chip in the DX100.
