I don’t have experience with the TT2 but the original TT is incredible with the Stellia, giving a detailed, clean and clear sound that opens up a window into the music. The TT and Stella bring out the best in one another, challenging each other to go to ever greater heights.I'm now considering the TT2, I know I've only just bought the Mojo 2 but I'm impressed with the Chord sound. I also have a Focal Arche which I'm not over the moon about sound wise. Do you think the TT2 is that much better than say the Mojo? I know there is a price difference but that's what happens with Hifi.
I guess I could sell the Focal Arche and the two Mojo's.
The original Mojo punched well above its weight too, so much so that at the time of its release it was being used as a DAC in two-channel systems by some audiophiles! I hear great things about the Mojo 2, so why not listen to the Stella with that in your chain for a little while and see what, if anything, you feel is missing with the sound?
In the meantime, see if any dealers will loan you a demo TT2 for a few days and compare the two side by side. I have demoed a few pieces of kit this way and it has only cost me courier fees - unless I bought the item itself of course!
