Well Gryphon and Audionet are two pretty different presentations.Ghyphon is very organic, meaty, physical bass, beautiful deph and yet detailed and fast.Audionet is very high detail retrieval, very low noise floor, huge soundtage, ultra fast and very natural.Both are awsome, not an easy decision.Those explanations are far removed from the prefect preamp. Save your money.
Now try direct in this a/b/c and hear which is the most transparent/dynamic and uncolored.
The Totaldac is what my reviewer/editor friend has, with the Wilson Alexia MkII and the Gryphon Antillion Evo, of all the ways we tried direct was the best by far, followed by a passive pre, even against his top of the line Supratek preamp.
