Reading this thread has very much interested me in the Vali2, and I was wondering; how does the Vali2 compare to the Lyr3?
Upon first blush... The Lyr3,
by default uses a larger tube (the 6SN7). For my Vali2, I have to use
socket savers (in order to clear the chassis) and adapter to use 6SN7 tubes. I also consider the Lyr's
volume knob (potentiometer) to be superior to my Vali (that's why I had to modify its knob). Both of these units use
just 1 tube -- and that makes it a hell of a lot cheaper to play around with different tubes (mind you, I need to purchased
balanced triodes; FAQ #6 [at Tube Depot, it's $2/tube extra]). The Lyr3's an
all-in-one unit... I'm running 2 or 3 little brushed aluminum boxes (Vali + EITR + ModiMB + Cthulhu power supply) to get the similar effect. I like clutter

& copious shiny things. I've been lucky - I don't suffer detectable
electromagnetic interference (EMI) from the various boxes, floor warts, cables, power bars, and wall warts. I'd assume the Lyr3 might be assembled to minimize EMI .
Aesthetically, I think the Lyr is more streamlined than my boxes.
I suspect at the end of the day, my set up sounds identical to the Lyr3. I'm restricted to headphones (no towers-of-2-channel-power for me).
I like my Vali because it allows me to safely play with different gizmos.
@tafens , I assume you're just comparing their
amplification prowess. I suspect like my Vali3 (and Magni3), the Lyr will drive my Sennheiser HD650 clones (from Massdrop) just fine. I'd recommend the Lyr if I wanted a one-stop-shop device. My 2 cents...
