Also, whilst the TR has more base ROM with its doubled extended ROM, you can put the KORG EXB-PCM expansion boards in the TC for more ROM samples that are arguably (mostly) better than the TR's extended set.
The TR was mainly intended as a 'cheap' version of the Triton range. Often in second hand prices though the TR is more expensive as it is newer.
For example I bought the TR new for £700. At the time I was not aware I could have bought a used triton for less than £400. I recently upgraded to a KARMA which still only cost £350.

It has slitly better D/A converters, so u will have a bit better overal sound.
but i don't know if it is with all Triton Classics but mine had anoin white noise,it was ok for practice but for recording it was impossible, while tr had it at minimal level while for recording it was immposible to
my advice will be i would preffer Triton Classic over TR but if u can, get Triton Studio or better Triton Extreme.
Triton Studio is very the same to Classic but in the same time it is not.
some critical futures are
1)It has better D/A, A/D converters.
2)It has 5 slots for expension boards
3)More effects
