depends on kind opf speed metal.No it really will be pretty big difference am loyal to VPI but cannot remember if FATBOB is multi arm.You have those upgrades like clamp and different cartridge for different music is cheaper (usually) if don't need second arm just to a buy a tube.Me I am pretty tight so going to sell big Aries and get Scoutmaster with 9" arm and $1K heavy platter.I'll give up VTA on fly which is nice if say you play lot's of 200 gm re-issues but going with Scoutmaster or Aries with 9" arm can still get up there (scoutmaster w/23 lp heavy is $3700 plus $400 per extra tube,SDS,clamp that's about $6K).I just balk at cost of 10.6 tubes though hey are better.I can't get by without one stereo and one mono at least.Not everybody cares that much.And of course listen to both side by side if you can.would if I could afford it a TW Raven or even Scheur Eurolab with one SME IV,and maybe Origin 250 for lesser carts all 2 or 3 hooked into Rhea stage.Bu not in current budget.I guess since your taste in music are varies and decks don't sound same think about flexibility and total outlay is abbreviated way of last paragraph.
