the problem I have is with some recordings using that combo, is there's an edge to the sound that's uncomfortable.
Do you get that same edge with IanG's LL? I wonder if the 009 is just so transparent it shows everything (including weaknesses)
I know you have a great source (Esoteric) but that is Over Sampling technology. I ran with that for years with less money DACs but still supposed to be good (Naim and Meridian(
then I discovered None Oversampling tubed DACs by Audio Note which did it for me. The dreaded treble digititous to many recordings was gone, and replaced by smooth (and detailed)
organic music, less hi-fi and steely / false, and more tactile and real sounding. Also the DAC I use has NO digital filet, it has been removed, and the difference is remarkable. It doesn't lift
the treble energy, rather, it removes the last bit of grain and also lets the tiny ambient sounds come through.
I would recommend trying an Audio Note DAC 3.1 for example. If you ring Peter Q at Audio Note UK, he might loan you one if you leave a deposit.
I'll bet it will be a keeper. You could use the Esoteric as your CDP only.
