I have the Woo Audio WA 33 with the upgraded tubes, and love it! The Woo has plenty of power for virtually any headphone, with sufficient head room that results in a very enjoyable listening experience. Although tube based, the highs are certainly presented well, as are the lowest notes. Not surprisingly, the mods are fantastic.
TOTL Headphone Amps
Looking for some feedback on what TOTL headphone amps people are using. I used a Auralic Taurus MkII for a couple years, and I'm currently using a Rogue Audio RH-5. I'm considering moving on to a Moon 430HA. Has anyone tried the 430HA and RH-5? Are there other headphone amps in this price range that I should be considering?
