Regarding Tyll(sp?)'s review on Inner Fidelity, according to Jack Woo of Woo Audio, the WES not only had the stock tubes but was not broken in (it was brand new). As WES owners reported here, the amp requires 250-500 hours before sounding right. I'm surprised that a respected reviewer would test an amp that wasn't broken in!
