Okay, I've done a little more searching and reading through various parts of the forums. I've also come to the conclusion that I'm definitely overthinking things, like I'm in the mindset that "If I don't like the amp, I'm stuck with it." Except I can always sell it if that happens. Now, there doesn't seem to be a universal consensus on anything for (relatively) inexpensive tube amps. From the way people describe them, these are my impressions:
- I could like either the Valhalla or the Lyr for their sounds by their general descriptions (Valhalla's supposedly warmer, Lyr's got less warmth but also some liveliness and detail?), and Schiit's 5-year warranty is pretty awesome (but I'll have to find out if it applies to Canadian/non-US customers). The Lyr also gives you some flexibility.
- The Bottlehead Crack tends to be described in vague terms but is supposed to be "great" with the 880s, but usually suggested because it's cheaper thanks to being a DIY solution, and I don't have any equipment to deal with that.
- The Hifiman is supposed to be pretty good for high impedance headphones, and is supposedly more flexible and can be used with lower impedance ones, too, if you decide to replace your 880s with something else.
- The Little Dot MK III and Darkvoice 336 are kind of lackluster unless you spend more time and money to find great tubes for them.
The problem is that most of it probably comes down to matters of personal taste and what everybody likes in their own sound. Maybe I should just pick something and hope for the best. It's not like it can't be replaced, right? I might just go with a Schiit.
Has anybody used both the Valhalla and Lyr with these headphones and could compare them?
