Can anyone help me?
I have been using a Chord Hugo DAC in one of my systems for a few years, fed by a Sonore mocroRendu. This was originally via the hi-def USB input on the Hugo, but around 6 months or so, I purchased a Gustard U12 USB to SPDIF convertor, and so input to the Hugo has recently been via SPDIF (coaxial), and I found that this improved the SQ a bit.
I have now encountered a strange problem and I wonder if anyone can help or advise. Out of the blue one day, after a glitch with my amplifier, I could no longer get any sound from my Hugo streaming set up via my amp (Krell AV Pre/Processor). For reasons I won't go into, I initially suspected a problem with the analogue input circuits in my amp. However, I discovered by attaching a different streamer that the amp's analogue inputs were OK, so my suspicion was now that the Hugo had developed a fault. As a final test, I then switched from the coaxial input on the Hugo (via the Gustard) to a direct USB connection between the microRendu and the Hugo, and was surprised to find that this was also working OK.
So I am left with the situation that the problem has been isolated to the coaxial connection or the coaxial circuitry in the Hugo. I would suspect that the Gustard was at fault were it not for the fact that it continues to accurately identify the type of music stream that is passed to it by the midroRendu, and when using the coaxial connection the Hugo also recognises the type of music stream fed to it from the Gustard, i.e it displays the appropriate bit rate colour for the different bit rate files fed to it.
Has anyone else encountered a problem with the Hugo of this sort? Is it conceivable that the Hugo has developed a fault that only affects output from a coaxial source, despite the fact that (because of the accurate colour changes) the input stream via coaxial seems ok?
I'd be very grateful for any help or advice.
