I'm sorry, that's painful. I love how my (non-LTD) VO pairs with tube amps -- started with Lyr 3, then Apex Peak (rare discontinued) hybrids, now full-tube (also rare discontinued) Eddie Current Aficionado. Yggdrasil>EC Af>VO is a magical combo. Although life's realities (outside noise, not bothering my better 1/2, instant power-on) make me use VC with a SS amp more these days.
Now you got me interested to talk about my pet love - tube amps. I once went to pick up a Jotunheim 1 from a seller and while testing it, he had the EC Aficionado there. I left with the Jot but forgot to ask to audition his Aficionado, much to my regret.
Over the years, I've been through quite a few tube amps, beginning with Elise, Euforia, La Figaro 339, Glenn OTL amp that has 7 sockets, ALO Audio Studio Six, Oblivion by Ultrasonic Studio, Woo Audio Wa22. Now I'm interested in a DNA Stratus. Heard Hugo TT2 + M Scalar > Auris Nirvana > Susvara and that was good but way too expensive.
SS amps wise, I've had Ragnarok, Jotunheim, Burson Conductor V2+, Violectric v280, Mjolnir2 (well hybrid), Questyle CMA 12.
Dacs are Yggdrasil (still the original) and now Bifrost 2. Might upgrade Yggdrasil - keep delaying it - by the time I decide, it could be a Yggdrasil 3 already lol.
So yes back to ZMF headphones. I've had Eikon, Atticus and Verite Open. I'm very sure I'll get another Verite again. This hobby is too engrossing.
You make a good point. Solid states are convenient - instant power on.
