Consider a tube DAC like Lampizator, I have a Baltic 4 with volume control, IMO the best DAC under $10K, and replace your Node with either a Lumin U1 or Innuos Pulsar. Without a good streamer you won't fully exploit your new DAC's capabilities.
Ideon DAC's
Been looking for a DAC/Streamer for about 1 year and still have not decided on one. My system is pretty basic, which started out as a dedicated home theater and decided I want to stream music. Currently streaming from Qobuz from via my IPad.
I was introduced to Ideon (never heard of previously). Was thinking of the following two products. Ayazi or Ion dac+ preamp with a Bluesound node.
Current system is as follows:
ATI 4005 amp
Marantz AV7706 processor
Sonus Faber Sonneto V Speakers
Any input or other recommendations would be greatly appreciated. Thanks.
