How good of a DAC is the Logitech Transporter

The low-jitter attribute of wireless also applies to regular wired connection. Many actually prefer wired over wireless because of the reduction in emi/emf from turning off the radio antenna/receiver in TP.

yes chesebert, i was going ask that, i have no problem using wired, well, of course wireless is always attractive because it is convenient, but i guesss i would overcome the "inconvenience" to gain performance.

Sure, wireless or wired with LAN cable, the clock jitter remains very low. Of course, you can experiment and see if you hear a difference between the two.

Best,

i doubt i would be able to hear the difference though, i mean between wireless and wired.

i know the Transporter doesn't have USB, but how would USB compare to network or S/PDIF performance wise? as high end as the Transporter is, it's a shame Logitech/Slim Devices forgot to include something as simple as an USB, which even a dirt cheap transport/streamer would have one these days.

I believe a USB solution would still ultimately involve an S/PDIF conversion operation - and thus there would be no reason to use USB with a Transporter. A main feature of these SlimDevices units is to avoid any such S/PDIF conversions - the network connection avoids S/PDIF and gives an optimum connection medium.

Also, regarding whether there are "better" AKM dac chips available, keep in mind that Sean Adams (designer of the Transporter) implemented the chosen AKM dac chip in a very optimized way. Here's a quote-snip from him:

Sean Adams: "However, in the case of Transporter there is a very large improvement over the manufacturer's specs because we are using the chip in a far more advanced design than AKM's evaluation board. For the THD+N figures this is especially due to the jung regs and the selection of certain passives in the amps/filters. The clocks are very important too, but this isn't meaningfully reflected in THD+N tests."
