Hi, I don't have a TW but have used the Boston mat1. The main character of this mat is that it roll's off the highs too much. That's why i sold it. The Boston sounds slow and sluggish. Good for bright sounding turntables.
If you want a nice sounding combo, try the Harmonix TU-800exi mat along with an HRS clamp
