I received a singxer SU-6 yesterday and immediately put it in the system in place of the sonore ultradigital between my aurender and my 005. Immediately, I noticed what I can best describe as a strident, edgy and "bad digital" character. The system remained very detailed but the realistic and pleasant character of instruments and vocals was diminished. The joy and involvement seemed sucked out of my system. I let it burn in overnight by playing music continually through it. I sat and listened late morning today. My system was better than yesterday but still not particularly engaging.
A couple hours ago, I swapped back in the sonore and my system was immediately better and far more enjoyable than using the singxer. I'm going to listen to the system for a couple days and swap back in the singxer. But, I'm relatively certain I still will prefer the sonore.
I may order and try an LKS USB 100. I do prefer my system using the sonore feeding the 005 through HDMI over running the aurender through USB directly into the 005.
What I believe I'm learning is there are solutions that provide better sq than straight usb out of the aurender into the 005.
Are there recommendations for USB renderers less costly that the innuos phoenix? I may want to go in that direction.
