Best DAC for my situation...Read on!


So thoughts and opinions please.
What I have and my idea.
Oppo 105D and Bluesound Vault 2 feeding into McIntosh C48 preamp.
I chose the C48 because it is a nice complete all in one box solution, headphone amp, mm and mc phono amp, lots of analog inputs with 2 sets of xlr inputs AND 5 total digital inputs.
Now I have both the Oppo and the vault connected by analog and digital inputs to the C48 so I can compare modes pretty instantly and I have to admit both cases the analog sounds better.
Which makes me wonder if the C48, although a great all in one solution may be the hold up as far as the DAC performance is concerned.

What I was considering as a trial is a seperate DAC that can handle the digital signals from the units and then output the analog signal via xlr preferably, back to the C48.
At this stage I have no intention of getting rid of the C48 as I really like the analog signal SQ as well as the headphone performance.

Any good suggestions in the range of $2000 used or am I really not going to see much improvement at that price range over the C48 capability?

I agree with you but with with a caveat: not all line level equipment has high quality output - so I would restrict my choice to go without a preamp only when using a very high quality DAC with excellent and powerful output circuits. Some power amplifiers and long cable runs may introduce a challenging load to a cheap line level DAC output and result in signal degradation (usually a loss of dynamics). So a preamp is just like an audio mixer in the pro music world - it buffers the line level signal by presenting a high impedance easy load and then has a powerful output that can often drive a more difficult load.

Schiit is not in the same ball park or league as Mytek and Benchmark and Bricasti and Bryston and a few others (lots of choice - Stereophile A and A+ is a good start)
+1 Ayre Codex DAC.   I own the Ayre Codex DAC and it is outstanding and highly recommended (new or used).  It has great performance and can be used as either a preamp/DAC or DAC only. Please see:

The Ayre Codex does not have digital coax input though from what I read.
Mainly a usb DAC I think

@uberwaltz

Your are correct that the Ayre Codex DAC does not include a digital coax input (it should but does not).  The Ayre Codex DAC specs are:
Input
USB : PCM 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz, 352.8 kHz, 384 kHz (up to 24 bits), DSD64, DSD128 

Optical input (Toslink)

Yeah I thought so pity.
I really need two digital inputs from my oppo and the vault and prefer them to both be coax but could be one coax, one optical. That is mostly because I have 2 fairly decent coax cables whereas my optical cables are just the ultra thin cheap giveaway stuff atm.
