As I've written earlier in an other thread about suitable amplifiers for Denon AH-Dx000 and Fostex TH-x00, I've got a Violectric HPA V200 as well. See full and (normally) updated equipment list in my profile. So far it has seen little use. For quiet some time I've mostly used the Grace Design m903. I will revisit it, but I don't know when. At the moment I'm more curious about other items.
It isn't obvious to me and at least fellow Norwegian achri-d that Violectric HPA V200 is (any) better than the very good and versatile Grace Design m903, maybe the contrary, maybe a question of taste.
In addition to appearing on Head-Fi.org, achri-d contributes in the Norwegian forum Hifisentralen and writes for the Norwegian hi-fi magazine "Fidelity". He wrote about HiFiMAN HE-500 and HE-6 in issue 57, and Audeze LCD3 in issue 59 using several of his amplifiers and headphones for comparison. The magazines can be freely downloaded as PDFs 12-18 months after publishing. He owns some well regarded headphones and amplifiers (see listing in his profile). He has owned or had on loan the Violectric HPA V200 as well.
Great info! Thanks, I'll check it out!! And once you've had them for a bit, if you feel like comparing the m903 vs Hilo vs V200, I imagine you'll find a pretty receptive audience...
