Got some 1958 d-getter BBs from the man. They sound great even after only about 5-10 hours. They sounded closed in and congested at first (about 10 mins, little patience with new tubes). But after a couple of hours,they started to open up and already, they sound wonderful (and they will only get better); great bass, superbly smooth mids and nice realistic highs with lots of detail.
I also got some 1960 BB large o-getters and I have to say I am having problems finding a favourite between the two.
I think at this early point (again, only about 15 hours), the o-getters have smoother (wispier) highs, whilst the d-getters have a nicer, smoother mid-range. Both have very nice soundstage (both in and around the head, but not too wide) and female vocals particularly, sound sublime. Plenty of bass punch in both of them, with a nice bit of warmth too. They both sound very "tubey" to me.
I find it so hard a/b-ing, cos once you have turned off the Lyr, let it cool down, taken one pair out, popped them in the nicely-labelled boxes, taken the others out of theirs and put them in, and given everything time to warm up, a good hour might have gone by.
I am just loving every track I play right now. I can listen for hours without any fatigue. This is why I bought the Lyr and spent a small fortune on tubes.
