Thanks, sns, these are very interesting conclusion and may well cost me some money!
As I've said previously, I settled many months ago on feeding my 005 through I2s using the LKS usb 100 with matching power supply as my DDC. It beats usb in my system, which is quite incredible. But, I sense there is more available and I may buy a Gaia after returning from an international trip I am taking next week. That may be followed by an 006.
Please continue to offer you impressions as you listen more. Your reports are much appreciated.
