DAC Shootout Starts This Weekend

So...I have been in the process of re-basing our DAC knowledge base as the system has finally been forced to change.  Very simply, the Vivid Kaya 45s are sold and with that departure, I figured I ought to move to my new reference system for purposes of testing.  

Basically, I am relistening to DACs in the new system.  I did some of this before the departure of the Vivids and moved the DAC to the new system.  I am no longer an official Vivid dealer.  Vivid moved to a new distributor and they have rules within their distribution agreement I am 100% sure I am going to want to break.  Rather than violate the dealer agreement, I figured we would part ways and be friends.  If they change their rules, I would be happy to pick the line up again

So....the new system consists of Wilson Benesch Discovery 3Zeros, a Canor Hyperion P1 Preamp, Virtus M1 Mono-Blocks and the source is the Antipodes Oladra server.  This is a bit more esoteric but tonally it is VERY similar to AVM and Vivid which was set up side-by-side as a comparison. It is just radically superior in terms of staging, detail and holography.  ICs and SCs are Inakustic 2404 and all power cables are Puritan Ultimate XX and it is routed through a Puritan 1512. The room is treated with Vicoustic diffusers, wall panels and bass traps.  

This is a system and room that have been optimized together so I should be able to extract every drop of performance from each DAC. The re-basing process is done and I look forward to writing up new Units.  Two will follow shortly for the Soulnote D-2 and the Lumin X1.

So the Lumin X1 came in to me from a friendly dealer who has one and allowed me to spend some time with it.  

The X1 is a hefty unit with an outboard power supply, has a built-in volume control and is a full-fledged streamer with Lumin producing its own software.  It retails at $14K. Given this unit is a full streamer with volume control, my feeling is that it is more appropriate to compare to the ~$10K DACs rather than the price point above.  

I swapped the unit in place of my everyday DAC (the Playback Designs MPD-6) and let it run.  The DAC has been used and is burnt in so just a matter of warm-up and letting things get settled.  

Opening track of In a Sentimental Mood - piano has good sparkle.  Drum rolls lack absolute definition of Weiss or Rockna Edition but detail is very good. 

On Be Still My Beating Heart, it is obvious that the X1 is a bit brighter/more forward than the Playback meaning it is probably a touch forward overall.  That said (based on notes) it is MUCH less bright than the Lumin T2.  The forwardness is present in staging but does not come through in terms of sibilance.  The sound stage is big and deep.  It extended well beyond the outside of the speakers.  Noise floor is very low.  When there should not be noise, there is no noise.  

Liberty is the same.  Forward but not sibilant. effects come from where they should, well beyond the boundaries of the speakers.  

Duende is superb.  Opening bass notes are clear and undistorted.  Dynamics are big.  String separation is fabulous on the berg piece.  There is nothing not to like.

This unit is extremely competitive in the $10K price range.  Compared to the MPD-6, the image is just smaller, has less depth and a hair less detailed.  Given the Playback, comparably equipped with on-board streamer is $18K, this should be the case.  

What surprised me most is how similar this unit sounds to another DAC I have on hand - the Soulnote.  But more on that in the write up of the Soulnote

@verdantaudio You should try the X1 USB stream out to the MPD-6 to compare the streaming abilities of the X1 to the PLink (which I assume you use on the MPD-6). The streamer on the X1 is really good, especially using Fibre Optic as an input. I still have not heard my PLink which is sitting under my desk.

I use my X1 as a SPDIF streamer to the Peachtree GAN1 (that you tested) and also as a XLR analog output to my RAAL VM-1a headphone amp. In both cases, it is a great result with a very advanced forward-looking user interface.

My GAN1 is not the stock version you heard; it is a modded version that I think is as good as my X1 going into a my 2-channel amps.

@yyzsantabarbara - so, I can test the X1 output.  I am not using PLink.  Just USB vs Ethernet.  I did AB testing with the X1, the Soulnote and the MPD-6.  I had two of the three connected to my preamp at at time.  Both connected to my Oladra, X1 via Ethernet direct connect and the other DAC (Playback or Soulnote) via USB.  
 

the Soulnote and the X1 sounded VERY similar.  The MPD-6 is a clear step forward in virtually every way, even using an inferior connection.  It sounds bigger, more detailed and more holographic than the X1.  The soundstage had more depth and height/width.  The X1 is excellent.  The MPD-6 is just better.  
 

@verdantaudio Which Soulnote do you have and does it have an outboard clock? The website has a model 1, 2, and 3, and some require an outboard clock to function.
