Wow, that is interesting. These Mullard reissues I have are Cryo'd and when listening for weeks or months without keeping track it was a little tricky for Greg to know exactly the hours (we arrived at a minimum of 150 hours). But these tubes have changed notably since I got them.
Maybe it is the Torii circuit, or that in combination with the HR-1s, but the bass/low mids have clarified and the upper mids and highs have smoothed. There was more disparity between mid/bass and mids, with too dense a bass/mid bass for my tastes, and a particularly (and not unpleasant) textural thing happening in the upper mids. As they clarify and smoothed out, I really like the balance between the tube's sweetish highs, its warm, open mids, and deep (now clarified enough) bass. I might have called them interesting before, but not balanced as I perceive them to be for the most part now.
I did play them in the Rachel I am auditioning, and they were particularly beautiful in it by my ears too. A different sound that was particularly friendly and musical. I would say sweet and musical with no down side.
