Because its not theirs and they want you to have a choice, i.e. spend a couple of hundred for a tss or a couple of thousand for a vibraplane. Its up to you, but you do need isolation due to the design.

Also you dont have to use their arm and cartridge and I am sure many dont - though they are both very good. My friend uses a breuer arm with his yorke.

You cant buy the tube psu anymore in the uk - also it doesnt sound better it sounds different so is a choice really at purchase time.

There is no upgrade / monopoly thing - they only make one arm and cartridge. Even with the support its still cheaper than an sme30. And with the appropriate support it sounds better IMHO.

It isnt nonsense if it is part of the way the deck is meant to operate. Its nothing to do with confidnece in the product or just plonking it in to the system. Would you expect an SEM to work without the appropriate isolation? With that logic well i want a deck where you can just install the arm and cartridge any old how and it works

perfectly regardless of alignment. Sorry but decks just dont work that way.

I can assure it does sound different and can demonstrate it very easily just by letting the air out...

Suspended decks might sound fine on ikea but non-suspended are not going to do that. But with the proper external isolation you can get all the benifits of suspension (and more) with none of the disadvantages.
