I had been in communication with Dan by email since I saw the video review at Cam Jam NYC and he has answered all my questions and been very responsive. I just finished reading the thread and decided to get Beryllium .
I am big planar hedphone sound fan and just wonder what type of soundstage these will produce vs my HE400I or soon to be determined Mr Speakers AEON's ?
I know these will be easy to drive .
Will put up a review when I get them and spend some time with them.
I think you will be pleased with the soundstage of the BE. I'm also a Planar fan. I listen to the LCD3 in the evening. The Periodic BE has become my go-to for listening at work and during lunch. I'm listening to the BE right out of the iPhone right now (Bon Iver's new album) and the sound stage is plenty wide and deep for me.
I'm very curious about your impressions once you get them!
