Yes, it is fun modding and pushing classic tables to their max. You get your hands dirty, have more skin in the game and end up with something personal. Besides, it is alot of fun, too.
Right now I'm listening to my maxed out 150 with a Michell Tecnoarm arm and modded Denon 103. This table will tell you what your cartridge is doing, both the good and bad. It's fun shaping out the Denon for either of my modded Benz cartridges. It certainly give me a different window to view through.
My td850 has a current audiomods arm which is handing what my benz m.9 delivers. It has carbon fiber boards and a origin live motor. This table plays as well as any VPI. That is not to talk down VPI, as I feel that make great tables but rather to point out that there are alternative paths to get you there.
That being said, the 160 series can bring a great deal of fun but it does have limits to how far it can go. However, replacing the stock arm will get a great deal more out of the table.
What ever way you end up going you are asking all the right questions and going in the right direction.
