Best DAC For My Setup Under $10k


Just wanted to get you thoughts on possible DAC replacements for my system with a budget under $10k (new or used) that would go well with my setup. My system consists of McIntosh MA352 integrated, Wilson Sabrinas, DCS Network Bridge and a Chord Qutest DAC (with a upgraded power supply) which I want to replace. I mostly do streaming for my listening.

Here are my current contenders:
DCS Debussy
Berkeley Alpha DAC 2
DCS Scarlatti (used)

I would also consider all in one systems (streamer and DAC) that would partner well with my gear.

Thanks in advance!

Just curious: is there a specific deficiency in the Qutest that you are trying to address or do you just want a change?
+1 to soix's question...

what are you trying to improve over the qutest?

m scaler might be the ticket if you want more smoothness and dimensionality to go with the crystalline dynamic sound of the qutest

I am also curious why you are not moving up the Chord line of Dac’s I couldn’t believe the performance for the money Qutest Delivered
The Lumin X-1 is an awesome DAC / Streamer.  I have owned the D2, A-1, U1 mini and now the X-1.  I am about to upgrade to a Lampi Pacific and could sell the X1.  If interested to know more about Lumin send me a private email.  
I own the PS Audio Directstream with Bridge II. It is excellent.  But I’ve placed it in a smaller system, because once I heard the Mola Mola Tambaqui, I was toast.  It’s a really really good DAC.  Detailed and clean joined forces with musical and enchanting.  Not thin.  Not dry.  Not clinical.  But not thick.  Not over-ripe.  Goldilocks.  Not one of these DACs that ever-so-subtly rolls off HF to calm down the presentation, which is just laziness.  You can get it for $11,000 or so if you try.  It’s killer.
