Duet to Touch for next upgrade?


Current 2 channel system:
Marantz sr6005
Bryston 2bst
Lite Audio dac 60 upgraded
Gallo 3.1
Squeezebox duet
Also used for HT with additional equipt.
Have been seriously considering upgrading to a seperate preamp but have now turned my thinking to getting a sb touch. The thought is that I should start with the best source and work up from there.
Reading here and elsewhere seems to indicate that the touch is much better than the duet in all areas and that with the Soundcheck toolbox tweaks it is even better. Originally I had thought it was just the dac in the touch but now I seem to be seeing that there is much more to it.
Is the touch the right first step for the biggest bang for buck?
Thanks

If I already had Duet and looking to upgrade I would get the DAC right first then move up to latest and greatest player device.

Touch is about due for a successor soon I would think and I would expect that to up the ante still at this stage.
Lots of great information. Appreciate the suggestions. Really have enjoyed the dac60 and for now plan to keep it in the system.
For now will keep the duet and research a pre.

Mapman- Under "normal" audiophile rules (an oxymoron if ever I wrote one) I'd agree, but my HP amp (Ray Samuels Hornet) also has a DAC and since it's just for occassional night use, I'm gonna keep it small and simple. Thx for the advice tho, and you are probably correct about a successor for the Touch.
