Thanks for the reply. There is remarkably little information available from Australian posters on websites. I already have a forward speaker based system, do not wish to add to that.
The most informative info is currently on the US Audiomart forum. A guy with the handle of Tubelover has a very detailed topic going on there: 142 pages. Over the top/too complex IMO, but enlightening nevertheless. He does score the Yellowtec higher than my Audiophilleo :).
@bhobba and @Gieseler Audio are playing with the different Aries models at the moment. Bill wants to compare it to the PS Audio bridge.
I have found new and demo units of all the Aries models in Australia. Several used models overseas.
I will see how it goes, I might just source a few used SOtM, Sonore, Auralic Aries streamers and then usb spdif converters as well as power supplies and bring to the Gold Coast for a GTG.
When I am ready for comparisons I will let you know - if you still have the Yellowtec I would like to listen to it.
