Well for what it is worth I bought a Berning Micro ZOTL to use as a headphone amp. As luck would have it the one I bought could also be used as a line stage preamp, as well as a 1 watt amp.
I've been using it as a preamp for a month or so now, alternating between my other passive preamps. I still prefer passives and will be getting another one that is balanced, but this Berning has really made a nice difference in my system.
I hope to be getting my custom EL-84 amp this week and will be setting up a second system with the Berning and a pair of Tonian Lab TL-D1 speakers I just purchased. Source will be a Kenwood KT-8300 analog FM Tuner to start, then a computer audio set up when I get around to acquiring the components.
