Lubes, I've heard the WPs with T+A amps on a number of occasions in a dealer system. IMHO, the T+A amp was performing at a lower level compared to BAT or Halcro amps in the same system. Not sure which model it was, but the T+A amp was holding the system back. Just my 2 cents.
I've had WP7s for a few years and used to use a Krell FPB-400cx. The power and bass was great but I agree with others here that that version of the Krell missed some midrange and HF magic. So, I've been on a search for tube amps too. FWIW, the best I've heard in my system so far are the Atmasphere MA1s. The have the very clean and open sound of OTLs. One more option to consider.
