Yeah, the auditor + T1 there is a lot of slam, and it's freaking fast. When I hear something that is slow and congested on the vali, I plug my T1 back in the auditor and everything is clear, fast and non-congested (in fact it make it sound like it's not a congested part of song, everything is detailed and the separation between instrument is really clear). The difference is so big. Day and night actually. Also the volume knob on the auditor doesn't compare to the small one on the Vali. I think I will move the vali in my bedroom and use it with my cellphone and my DT880. But in fact I think the Auditor is really impressive, I was a bit sceptical about the Vali, but for it's low price I don't regret it. Maybe I'm just not a tube guy.
