These things are awesome! They used to ship the A8 with STAX Ear Speakers... which when I discovered it almost 10 years ago was the first time I had ever heard the term "ear speakers" or had ever heard of electrostatic headphones, or the brand STAX (from Japan). All in all, The Realiser and the STAX were unbelievable! I got bored of the A8 after awhile but I never got bored of the STAX... I wish electrostatic headphones were more widely available in general, they're a true gem. Everyone that hears them is in awe.
