Check out what reviewers and users have to say about WA6. ---- "What I like about the WA6 is that us gives you a nice warm sound, without going too mellow. If your music needs punch and impact, the WA6 will give it to you any day of the week." - Mike, headfonia.com ---- "I never really knew how good the HD-600 could sound until hearing them through the WA6. Anyone that says HD-600s are dark or veiled hasn't tried the correct headphone amp." - rad212, Head-Fi.org
