FWIW, my "other" LO7D (the one I still own), came with the Kenwood record weight. I do not like what it does at all. In fact, my experience with this weight parallels all my other experiences with record weights; they seem to take some "life" out of the sound. I realize that that sense of liveliness could also be called "distortion" due to LP resonance, etc, but it is a kind of distortion that brings me closer to the experience of real music played by live musicians.
I think I already wrote this, but I agree with others that the SAEC mat is excellent (now using it on my SP10 Mk3). I would not be inclined to mess with the stock mat on the LO7D, because I think it was carefully engineered for the turntable, but I do not like the typical rubber mats that came with Technics, Denon, etc. (I used the SAEC on my Denon DP80, also with good results.) Which is to say to Halcro that there are lighter weight metallic or graphite or other types of mats that I believe would outperform the stock rubber Victor mat, which in photos looks like the Denon rubber mat. You might try Boston Audio Mat 2, if you don't fancy the SAEC SS300. I have the deja vu feeling I have said this all before, more than once. Mats make a crazy big difference, IMO.
