I wouldn't get the Vali with these 1) the Vali's 6.5 Ohm output impedance with the THX00's 25 Ohm impedance likely won't play together particularly well. That's only a 3.5ish dampening factor. You want at least 8, if not 10+. 2) These, if they're anything like their TH600, TH900 and DX000 brethren, need a lot of current thrown at them. The Vali has decent raw power, but doesn't push a whole lot of current 3) The one complaint about the THX00 has been that the bass can lack control at times, the Vali will exacerbate this.
