I think the Strad's and the 40.1's will give Joe all he needs. The Hegel with the right tube preamp and the right all tube rig as an alternative should put him over the top for a long time. He is set on the all tube front with the GAT/ART combo. With the GAT in house as a preamp, he may not need anything else to go with either the Hegel or the ART amps. Time to clean out the herd and look for a good mid-powered tube integrated. Line Magnetics or Leben come to mind or at a different price point the Primaluna/Mystere integrated amps. Just my opinion mind, as I have found you don't have to spend a fortune to get great sound if you choose wisely and pay little to no attention to the magazines flavor of the month.
