Sorry to raise an old thread, but looking at an RNS 510 but considering a new alternative for the same price with a lot of extras.
Anyone here used the ANS units by Audiosources... They are releasing a new DNS unit which looks very good spec, seem all the rage in Australia.
Are there any good alternatives to the RNS in this country? How quick is the RNS in practice too, as its a lot of money for a headunit with little more function than the standard mk6 unit?
