A friend who is a ESL user, as I am myself, builds Ribbon Headphones which require a purpose made Amp/Energiser?
I am not a Headphone user and after another who is an advocate of ESL's and Headphones brought their Stax Model for a comparison to the Ribbon Headphones, the positive reports on the experience captured my curiosity.
I was offered a chance to experience the Ribbon design in use, through a VAC Valve Amp, it took a few tracks for myself to settle and acclimatise to having encapsulated ears.
A CD I use for demo's was also used, about a half hour in to the demo'.
The Ribbon design produced a depth to the Soundstage and Details that I know about and will use to determine the quality of details being extracted from the recording. Using the Ribbon Headphone as the listening method, there was a very obvious presence of attractors, the depth was considerable and the details vivid, certain aspects are seemingly tangible.
A few tracks were repeated after the demo', through the ESL's. The Headphones were spectacular as a comparison, it really does require a lot from a Speaker in a Room to generate the sense that a performer is present and can be touched.
The Ribbon Headphones proved to be capable to to create being their presence with ease, and was a common experience, I will one day be set up to really enjoy opportunities to have periods where Headphones are in use in my own system.
