+1 The only fair way to compare them, is to connect both Touch and Transporter to some separate DAC. Even coax cables can sound different. I can not agree with some of your observations. Touch's bass is not boomy over SPDIF. Quite the opposite! I got much better defined (and even leaner) bass with Touch. I have really big speakers (refurbished vintage Acoustic Research AR-90) and they can sound boomy if something is not set right. And inexistent stereo separation? I didn't notice anything like that. Together with some friends, we compared Touch and Audiolab 8000CDM dedicated CD transport. They were feeding an old Wadia Digimaster X-32 DAC. The Touch was much better in role of digital transport. Also, that Wadia is known to be very selective regarding quality of transport feeding it. If transport is not of the highest quality it completely refuses to lock to the signal: > > > http://www.stereophile.com/digitalprocessors/wadia_digimaster_x-32_digital_processor/ > > There have, however, been some problems in the field because of this > circuit.

Wadia locked to its signal without any problems and this was not the case with some other transports that it's owner had tried previously. . -- Kuja ------------------------------------------------------------------------ Kuja's Profile: http://forums.slimdevices.com/member.php?userid=32935 View this thread: http://forums.slimdevices.com/showthread.php?t=79914
