We purchased a pair of tube amps from loonze. we had talked via messages and text messages about the amps. I asked him to tell me about the amps which he did except he left out the fact that they were heavely modded until I drove 1 1/2 hours to meet him. I connected the amps and they sounded nice until one developed a popping sound when any volume was added. I switched preamps and the problem was gone. How ever after about 30 minutes of very nice sound one of them died. I contacted Loonze and he was upset about it. He wont work with us in any fashion to resolve this issue. He is accusing us of hot swapping tubes and connecting them up wrong. Really how many ways are there to connect a mono block amp??? and we only had the tubes that he provided us one set and they were in the amp we have nothing to swap out!!!! He wont even answer me any more. I asked who built them so I can contact them and no response from Loonze at All! I am stuck with a set of amps that don't work $400.00 down the drain because Loonze wont work with us. I just don't get it I would never think of doing this to any one, the least he could have done was to help us get them repaired. Loonze is not a good person BEWARE!
