After having a discussion with another Head-Fi'er, I've decided that since I want to color my audio, a tube amp would work well for me. I'm not setting a budget for this because I'm not entirely certain what it costs to get a good entry-level tube amp. That said, while I've taken a gander at the Little Dot Tube Rolling thread, I'm not entirely in the know on tube amps and I don't know any good places to shop for different tubes.
I want one of these so that I can alter the mids and bring them out (as a lot of headphones have a recessed midrange, or just aren't very forward). I want to be able to hear vocals clearly. Which tubes should I consider for which amp? Keep in mind that this is my first headphone amplifier, so please don't get carried away and suggest a WA7 Fireflies to me (ugh, like I could afford that). I'll probably buy a solid-state amp later on, but for now, I want something I can experiment with.
tl;dr My questions are as follows:
- Good entry-level tube amp setup for midrange?
- Places I can shop reliably for tubes?
- A few suggestions for tubes, amp notwithstanding?
