Smokenjo,
The TP 2.3 fully loaded was a huge improvement in my system even before the DS DAC arrived. I cannot imagine my system without it.
Regarding sound stage, it is a wide and deep 3D stage with great imagining. But you must know that sound stand depends on more than the preamp (rolled with the best tubes) and DAC. Your speaker and power amp and cables and accessories including tweaks can have a huge impact here, as well. I have a zillion things in my system that contribute to sound stage.
