Hello audiophiles and experts, Recently I bought a second hand Sennheiser Unipolar 2000 but I found out later it was an electrostatic. I didn't receive the energizer and the previous owner didn't have it. Now I'm wondering if there's a variety of amps/energizers I can get for the Unipolar...

I bought an used Stax SR-207 together with a SRM-1 MKII (B serial number) a while ago. I instantly fell in love with them and now decided to upgrade to an L700 MKII. Now I'm thinking I maybe need to upgrade my amp or "energizer" as well. I read a lot through the different forums and reddit and...

I own a Woo Audio Wee, and i am looking for other energizers to power my Stax with, if it will make a difference or not sound-wise. I am running my Woo Wee on a Bryston 2B-LP, which is powering SR-007 Mk2s (port mod). Would exercise the idea of finding an energizer i can run off a powerful...
