Ooops, I had cut and pasted from MS Word & it appears I messed that up!
I got the Denon back from the ruby upgrade and burned it in so I was able to finally compare the two mats with a nice cartridge.
The Boston is more open and has a crystal clear high end- the lead/cork is very even and has an emphasis on the low end. I don't think the bass is deeper, just more of it. I have all tube gear and needed the high end clarity in that system. It so happens that my second system is solid state and the lead/cork was very nice there.
I like the BA in the tube system and the M/S in the solid state system.
