What we've done is increase the power and output transformer size, designed and built a larger Adaptive AutoBias board, and all the supporting circuitry required to run eight power tubes instead of four. Doubling the power and increasing bass slam.Customers can use almost any tube on the market. And their new DiaLogue Premium HP can be shipped with EL-34's, Gold Lion KT88's, or Tung-sol KT120's
The new headphone amp may be the best you ever heard. Why? It's running from all the power tubes! An elegant, well designed circuit allows you to switch from speakers to headphone as you wish. If you love private listening, this amp will wow you!
