I hear you, I bought my BE during the half off sale ($150) they had a few months back. Also, the only way you can listen to the tube mode on the Cayin N3PRO is thru 3.5mm, I tried 4.4 but tube mode thru 3.5mm sounded better.

I've had the Periodic BE for a few months now and am enjoying these a lot for Metal, hve them paired with Cayin N3 Pro

Hey, just wanted to run this by for some of you, in an earlier post someone was talking about the Periodic Audio Beryllium (BE) IEM's for $300 that were great for metal music. Right now on their website they have half off with code "birds". I just purchased some for $150

All my music is on Vinyl so I record my collection using Vinyl Studio, my whole collection is Hard Rock, Metal, Thrash and Death. I have the N3PRO paired with the Mee Audio Pinnacle P1 and love the sound of Metal with this setup. I've had the Pinnacles for a while and used them with the FiiO X7...

Sorry, what is tube noise exactly? I don't hear anything abnormal, I was really into my music last night for about 2 hours and everything sounded great to my ears.

I received my N3Pro and really like the Triode Mode so far and also love that it is non Android, just drag and drop my recorded vinyl collection and good to go. I did notice the back of the player scratches easily and I should have put the plastic case on immediately and all I did with it is...
