I bought a pair of drive tubes from Xenithon for my wa2. Great communication and great service, very fair price. Shipment was very fast too, the only occasion in my life so far when i was positively surprised by the postal services. They came VERY well packaged and did precisely as promised.
One of the best head-fiers out there an dI would not hesistate at all to do business with him again. HIGHLY recommended!!!
