What DAC would you use if you got the Mjolnir ? If you would be using a soundcard then, good as the Mjolnir is, DEFINITELY the Bifrost/Lyr combo ... the Lyr is amazing for the money - just get the GE tubes to start with ... then when you have saved up a little, buy a pair of Amperex tubes - Early Bugle Boys and Early Orange Globes are best ... but the Orange Globe "A-Frames" are also nice ... there's a tube rolling thread you can check out when you have a little more money, but for now, the Bifrost/Lyr combo is certainly not "chopped liver" !!
Yep, that's the point I don't have a DAC unless my Fiio X3 does count as a DAC with the Mjolnir...? But I doubt it'd be a viable combination. So I just go for the Lyr+Bydrost combo instead of Mjolnir alone.
Thanks for the tube suggestions kothganesh and NinjaHamster, I have yet to dig deeper in that issue. By the by, the factory tubes of the Lyr are that..."minimal" to those what you listed above? But I don't want to get off topic.
