Would it be a fair test though. Both of my Spec 1's were reworked to EW's recommendations and they are some FINE pre-amps after that. BUT, I will compare and report. I reworked a PL 3300 SEr II that came awfully close to em that I sent to Larry. It found it's way back and after I swap some op-amps it's going to Sutton. I've had the Grant Fidelity P 307 that Larry sent me and after I rolled the Chinese tubes out with a matched pair of Sylvania's sounded pretty damn good too.
