it looks like the M2Tech HiFace and Evo is SQ wise equal to a good modded Touch and maybe slightly better as it is simpler and therefore a "cleaner" context for the relevant music path. Also it can be modded further (PWS and clock mostly)
But there are also disadvantages. No screen, ( probably > 90% of the setups with a SB to Touch are not transparent enough to hear the diff between scr ON or OFF when the scr is shielded , a mod of Wayne)) no wireless, no remote control to search through yr musical database.
Through Touch like sources i can use my main PC instead of a laptop. The Hiface actually "begs" for a laptop to add a screen to it ( making it MUCH more expensive than a modded Touch if you can use yr main PC.) The advantage of a PC is I can use Intel M25 SSD ( solid state disk) of 160 Gig. I dunno if there are laptops who can do this as well? SSD via a USB link does not convince me as clean
