Which TNT? I have actually had both of these with SME IV arm and last year had a loaded Aries Extended with 12.7 arm. The good news is that either would be very good; I would lean toward the TNT but the 19 is also good. I think the TNT would give you better bass and a little bigger scale in general. I have found that larger and heavier tables generally have this effect while being a little less agile than lighter ones. YMMV. Since I am a VPI dealer and have been an SME dealer it is obvious I like both. 12" arms have advantages and disadvantages; the VPI is a unipiviot, the SME not. The SME is noted for bass production, the VPI perhaps has an edge in the higher frequencies; both are among the best available, at least at less than insane prices. So much is going to depend on electronics and speakers that I really have no idea how to tell how they would sound. Either will be suitable for a really good system.
