I have owned two Gustard models and have ran them direct to amp for years. No hiss no issues. Currently I am using the Willsenton R8 amp. Another large prototype Solid State as well. Very happy with them. I always thought I had a touch of digital siblance. The Jays audio transport removed it all! Very happy with Gustard. Thinking about the X26 pro. Just because??
