I'm using my recently acquired Bluesound Node 2i for streaming Qobuz HR content. My Node is connected to an Audiolab 6000A amplifier via both the optical and coaxial input, in order to use the amplifier's internal DAC for the decoding (the Audiolab 6000A's DAC suports a sampling rate of up to 192khz). I have successfully overcome the first hurdle of finding out I have to switch Qobuz to HD+ under Music Services. Now 192Khz signal is played by the streamer and is recognised by the amplifier's DAC. However, when playing files of 192 khz, the sound comes out noisy, with crackles and pops. Therefore - rather frustratingly - I simply cannot listen to music that comes in that resolution. Since HR is one of the selling points of the Node 2i, I am somewhat disappointed. I have contacted Audiolab and they are not aware of any such error in their DAC, nor have I encountered the issue on any discussion forums.
I have tried both optical and coaxial cables for the digital connection between the Node and the Audiolab and the problem persists for both. And before anyone is recommending me to check the cable quality, I am using Ecosse The Producer for the coaxial connection, which is relatively highly-regarded in the hi-fi world :-) Also I have checked the connectors on both ends with great care and they are certainly not the problem.
Could anyone kindly advise?
