I'm most definitely hooked on my electrostatics, and have yet to find dynamics that compare. Don't get me wrong, I still enjoy dynamics, especially the Sennheiser 580/600/650 series properly recabled with Cardas on the 580's) and MoonAudio Black Dragon and/or Stefan AudioArt Equinox cabling on the 600/650 series. . . .and properly driven (currently using either a HeadRoom Maxed Out or SAC KH 1000 amp - - or a seriously revamped/rebuilt LD MK III for that tube magic.
My electrostatic travels began with the Stax SR-X Mark3 to the still amazing SR-5 Gold Edition (Black) to the original and still sought after Lambda Normal Bias phones driven by either a SRD-7 Mk2 energizer and Marantz or Technics amp coupling or the SRM-1/Mk2 C Series amp. Along came a number of pro bias Stax phones from the LNS to my current SR-404 LE all being driven by a Stax SRM-T1 amp. And now I have achieved stats nirvana with my recent acquisition of a Baby Orpheus (Sennheiser HE 60) driven by a magnificent Cavalli Hybrid eXStatA. Has everything I want from a superior soundstage to crisp and well-articulated highs and a deep and extended bass with more than sufficient slam. Massive amounts of detail and presentation with very fast note attack and decay and thankfully not as dark as the O2's.
My current drug of choice as you can see are my HE 60's, with the following fave cans in no particular order - - HE-Audio Jades, Koss ESP-950's, Stax SR-404 LE, AKG K 1000's, Audeze LCD-2's, Sennheiser HD 600. As you can see, electrostatic and orthodynamic headphones dominate my stable.
