There is a lot of good info on this thread. I agree with the other Dazzo users. The Dazzo is so mic like that the TD makes it different, not necessarily better. If you decide that you like the new sound your getting from the HFN then definitely go with the Grace Alix. I owned one and it is a total quality piece of gear. If you believe you need to make corrections in the plugged in tone then go with the TD.
I am waiting for the Sunnaudio guys to come out with their full featured preamp DI. No need for AC power and high quality components. Their two channel version will be available soon and their one channel should come after that.
