I heard the EC/SS with the first opamp and the dynahi back-to-back about 6 months ago (sources: mod Denon 3910 and Apollo; cables: UR8s). Yet as a preface I think the dynahi is probably the best single-ended solid-state amp I’ve heard with the EC/SS coming a close second to my ear’s musical listening preference. The new AD811 opamp brings the EC/SS much closer in my estimation, but I think the dynahi would be superior—particularly with respect to, dynamics, imaging, instrument separation and soundstage (limited to my use w/ the HD650s). Both have what I perceive and describe as similar positive tube attributes with the EC/SS a bit more tube like. I would need to hear the dynahi and the new EC/SS (AD811) back-to-back, but I surmise I might still tilt my hat to the dynahi. Yet I can’t say it would be a done deal or that clean cut as before since the new EC/SS drives headphones in such a phenomenally musical way with warmth, energy, excitement, hyper revealing detail and extreme precise control. I didn't want to stop listening.
It should be noted, I’ve not heard the RS-1s on the dynahi and I believe the L3000s picked up some minor background noise even with the volume pot near supposedly inaudible listening levels, but I assume that could be fixed or minimized with an adjustment. Also, I preferred the HD650s over the K701s with the dynahi and Denon combo because the later headphone in that system touched on a sensitive I perceived as a bit piercing in the upper register. As far as I could tell today, the L3000s weren’t picking up anything on the EC/SS within safe listening levels without a source playing so I could test it.
