I have been a happy Aries G2 user for almost three months. So much so that I decided to replace my PS Audio Directstream dac (used Bridge II prior to the Aries) with the Vega G2/Leo GX. I ordered the combo two weeks ago. I received the Vega G2 one week ago and the Leo GX yesterday. The Vega G2 was super easy to set up as was my Aries G2 (I give Auralic high marks on ease of implementation). Needless to say I was very much looking forward to the addition of the Leo. I followed the video procedures for replacing the Vega cable which was quite easy to do. All terminations came with plastic protectors which I left on until they were necessarily removed and then re-attached where appropriate. Same with the upgraded coax cable, all terminations were protected until connecting. All work was accomplished in a clean environment.
Now to the problem. There is no music with the Leo in the chain with 48k and multiples of 48k. The sound is a combination of ticking/popping/screeching. Music is great with 44.1k and multiples of 44.1 wether it be 16 bit or 24 bit. I had zero issues regardless of sampling rates with the Aries G2/Vega G2 combo.
I called my dealer and was told they had one other Leo with the exact symptoms. When the unit was sent back to Auralic they were told the unit had dust in the coax connection. After blowing the connections out with compressed air the Leo functioned perfectly. Although I was somewhat skeptical of this explanation I did exactly that, blew out the connections on both the Vega and Leo as well as both ends of the coax cable.
After turning the stack back on and allowing the necessary hour for the Leo’s temperature to stabilize, I played both 44.1k and 48k tracks. No change. The 44.1k (and multiples of) play beautifully and a screeching mess out of 48k and multiples thereof.
I am utilizing Lightning Link with Audioquest Diamond HDMI between the Aries to Vega and Vega to Leo.
(I bought the second AQ cable with the thought of adding the Sirius when available knowing it is overkill Vega to Leo). Coax cable runs from Leo to Vega. So all connections are correct. Running 6.0 firmware.
All sampling rates play great without the Leo in the mix. Only sampling rates of 44.1 and multiples of play with the Leo in the chain.
I conclude that the 48k clock in the Leo is defective. Am I wrong?
