I am into open baffle (DIY Lii Audio F-15) and 45 tubes (Alan Eaton monoblocks). I am new to the site and learning as I go. If you are similar, I would love to see what you are using. I play many vinyl. Right not I am using a Music Hall 5.3 and Sutherland PHD, and Shiit Saga + modded with better caps. I am also looking to build a passive preamp with auto transformer and remote for volume control to replace the Shiit Saga.
