“ For some time I've been looking for a decent piece of kit to travel with. Previously I tried a HeadRoom Portable Desktop amp/dac, but didn't like the overall sound, though the DAC was good.

The HP-V8 is a different beast altogether. It's a tube amp using 300B, KT88 and E88CC tubes and is as large as some speaker based amplifiers. It's almost like an announcement that Fostex is stepping...” --AnakChan
“ Please bear with me, I'd consider myself still a noob when it comes to desktop DAC/Amps. Although I've heard a few DAC Amps in quite a few public headphone festivals, most aren't heard with my headphones nor my source tracks of music. And I'm still mostly learning from the gurus here in this forum and from Japan Head-Fiers. So this initial impressions will be somewhat...” --AnakChan
