Nice to see some more posts and experimentation here. Following up on my posts from last March - Since then I have rolled several more sets of tubes, from some very expensive Mullards to some uncommon RCA 7058s. I think 7 different sets in total. I kept coming back to the new production Gold Lions. On my system, they just flesh out vocals in a way all the others I've tried cannot. Naturally, curiosity got the best of me and I have a pair of Baldwins out for delivery today. Thanks @hifi59 . What's one more pair added to the collection? :) Will report back later.
Oh and the Petit did end up replacing my McIntosh MP-100. After making those changes, the holography and more natural sound of the Petit won out. By comparison, the MP-100 sounded a bit too lush and recessed. I have no desire to try any other phono stages at this point, though continuing to tinker with the Petit's tubes is sort of the itch I need to scratch.
