I did. The Z10E is a very nice amp. I’ve got a review partially written up. It really does give you the best of three worlds: electrostat amp, high/low power dynamic/planar amp, and speaker outputs. I think the amp sounds better on the Voce electrostats than the Stax 007/009/009S. It sounds superb with the MySphere 3.2, and very good with the Susvara. I ran the Susvara out of both the speaker terminals (the LTA folks made me a nice adapter free of extra charge) and the front ¼-inch jack set on high. I preferred the speaker terminal adapter, though LTA advises it was the same output. Shrug. I think the Z10E is better on the Susvara than my HeadAmp GS-X Mk2, and I love that amp. I think it’s probably a combination of the ZOTL circuitry, the tube airiness, and the bottom end that seems to have more authority. I had always wanted to try a ZOTL amp. Glad I finally did. Dead quiet, Excellent micro and macro detail, without being over-analytical. Not warm or gooey like some tubes, but instead organic and tactile.
If I could only have one amp, but still have a few headphones, including electrostats, this would probably be it. It lacks some of the flexibility I like, such as balanced outputs, preamp and/or loop, but it’s an excellent amp. Built like a tank. A bargain with the Voce bundle.About the only thing it can’t do convincingly is drive the RAAL | Requisite SR1a ribbon monitors, but then it wasn’t intended to//c
