Thanks for the responses so far. I plan to buy from Kevin, Dougstubes, Tubestore, or Grant Fidelity-- most likely Kevin. Will be going in Quad II-40's. Distributor requires full retube to upgrade to current specs. I can supply any set of Quads that I like. Not sure that I will have the upgrade performed, but would like to know my options. Amps will be used with Zu Essence. Shuagang Treasures are highly recommended but somewhat expensive at $450/matched quad.
Thanks again for any additional info.
