Best quote (and this is from a reviewer with a stable of totl HPs, and who has heard most of the best HP amps)
Clearly the core target audience are headfiers. Those who also run speaker systems are well advised to give the Lyr a go. But I'd not recommend that preamp buyers pursue the Lyr as primary target. Its illustrious headphone performance only diminishes in that application. To equal it as a preamp takes longer green. And to jump ahead, to exceed it as pure valve headphone amp could take $4,000 for an Eddie Current Balancing Act or fully tricked out Woo Audio Model 5.
I'd read that review, as well, and I'm still curious about the Lyr2 as a preamp. Even though I just picked up the Lyr2, I haven't yet hooked it up as a preamp. To those who have, I've got 2 questions:
1. Do your findings match the reviewer's? In other words, is there any reason Lyr2 wouldn't make a nice preamp?
2. Would tube rolling improve the sound as a preamp the same way it does as for the headphone amp?
Really loving my Lyr2, by the way, but I'm going to
try and avoid tube rolling as long as possible. We'll see how that goes.
