    Eufonika (Valve amps from Poland)

    Hi guys, has anyone had any experience with Eufonika? I spoke to someone the other day who had one and really liked it, I was intrigued and have requested a sample.

    Earnine Thread

    So I saw there wasn't a thread dedicated to Earnine, and feel there should be one as they offer superb value IEM's, I recently reviewed the EN120 which is a single BA IEM for under $50. They make their own BA's as they are owned by TSST, which makes them even more interesting.

    I don't suppose anyone has these? I've got them on loan for 6 weeks to review, maybe not worth the price ($2199.00) SQ wise, but the look, feel and build are certainly high end:
