I had a full boat Linn front end, went from an Arkiv to a Ruby 2 and then to a Basis 2500, Graham 2.2 and a Ruby 2. I prefer the Ruby in both arms because it tracks much better than the Arkiv, is a little warmer and is much cheaper to retip. Of course your priority may be different.
I wouldn't buy a new Linn today. My Linn dealer lost their LP 12 expert and you must have dealer support for this table. It's been many years since Linn has done anything new with analog and I suspect it may get more difficult to get service in years to come. The EKOS is nearly a fifteen year old design. Of course when you have the support the Linn system stills sounds great.
I went with the Basis/Graham because it sounds better to me and I don't need a local dealer. Set up and cartridge swapping is a snap. The engineering of the arm and table gives me great confidence they will work for many trouble free years.
My new set up has a more exact sense of space and better bass precision. The instruments of a string quartet can be more easily placed, side to side and front to back, than before. There are no drawbacks I can hear.
I suspect the Graham arm is the reason behind the improvement. A Graham 2.2 in a Linn would be interesting to hear. Unless you are very skilled in set up, or have absolute confidence your Linn dealer will be there ten years from now, go with the TNT. But, if you can consider the Basis.
