I know you are trying to be helpful and thanks. That said, I hope you won't take the following wrong way... [me looking at my picture] It is pretty clear that my LCD2.1's (~50ohm impedance) are being driven by a solid state THX AAA 789 (balanced) through a balanced reterminated silver cable (see my post). If you saw my signature, you will see a can (HD6XX) that pairs quite nicely with my Darkvoice OTL. I also made a post on reddit a few days ago warning against an OTL like the Darkvoice (6.3V rectifier tube) pairing with planars (funny that) since there's simply not enough current due to the DV's high output impendance (~70ohms or so) to feed current-hungry planars. Also, if the THX AAA 789's 6000 mW @ 32 ohms isn't a beefy solid state (listening at 9-10 o'clock on the lowest gain setting), then I don't know what is. Maybe you are thinking about SimAudio's Moon 430HA with 8000mW @ 32ohms on tap? Beyond those two, I would have to run the LCD2.1's through speaker taps.
