I too just play records and let it break in slowly. Given that cartridges only last a thousand (or maybe two thousand hours, if you are lucky), I hate giving away 10% or so of my cartridge's life on break-in. I might as well listen and enjoy how much better I like it once it is broken in.
And yes, the Glider II has a little bit of an HF edge to it. (I still consider it to be a good cartridge, because except for that, it sounds really good, and has pretty good frequency extension. It does lack a really deep dark background though. I eventually went to the Koetsu line to tame that HF and to get the really black backgrounds I was looking for; and of course the Koetsu mid-range magic.)
How do you like your Loricraft BTW?
Does it really do that much better job than hand cleaning and then vacuuming the record clean?
I have considered getting one at some point. (I have a nitty gritty 1.0 that I got for basically nothing, and it works pretty well. However, I think I might want to jump up past the usual step up in RCMs (i.e. the VPI units), and get either the Loricraft or the Keith Monks machine.
