it is also 99% implementation , you can get the best chips ever and still build a rubbish DAC :) The actual Performance of the Transporter exceeds those basic spec of the chipset .
Archimago measured like -115dB for the TP http://archimago.blogspot.se/2013/02/measurements-logitech-transporter.html And around -105 dB for Touch but worse crosstalk -90 dB http://archimago.blogspot.se/2013/02/measurements-logitech-squeezebox-touch.html So how the chip is implemeted is very important . The diff between these 2 products has more to do with the rest than the specific dac chip . I say without knowing to much :/ I could be talking out of my rear end , but(t) even the most costly of dacs sports silicon that really dont cost that much you pay for the rest . I have never designed a DAC so i think that was it for me ,this is just a tendency i've seen . However AKM seems well regarded so what gives ? If my memory serves me rigth the TP is very close to AKM's reference implementation and did not Sean Adams had some help from AKM ? That seem rational and sound to me ,why not ask the guys building the chips for advice instead of adding more quantum purifiers or whatnot :P . I think the TP is an endearing product its designed for real world performance it has what it needs to perform like this . I would expect much more over-design from the usual suspects in high end audio . Touch is build for a budget , but still it's much better than first DAC I owned in early 90's (and so is probably my phone ) so it may be relatively "compromised" . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
