As many of you know, I set out to audition a number of the leading DACs in my system with the goal of identifying the ideal fit for my ears. Below is a bit of a stream of consciousness summary of how it all sounded and went for me.
But, first please let me outline a few parameters and disclosures...
- These notes are my thoughts and impressions based on my impressions. They are not in any way meant as a declaration or even a proper review.
- Not all of the DACs were inserted in the system identically! Some of them were heard with a streamer or a clock or bespoke cables. I will try to identify the setups below. For those looking to 'sweep the knee' on this post - one DAC had a FTA USB while another had a $5 USB!
- Many DACs were connected to the pre-amp using Transparent Opus Gen 6 balanced interconnects that were not tuned for the DAC. The tuning of the interconnects makes a noticeable difference - more so depending on the variance from what it is tuned to vs. the actual component. I have noted where this was the case.
- I tried to remain consistent with music tracks for all DACs with music ranging from classical to rock to EDM to folk
- There was an attempt to equalize the sound pressure across all
- Each DAC was compared against a dCS Vivaldi Apex stack (Clock, Upsampler, DAC)
- DACs were setup with the Boulder 3010 using trim functions for equalizing so that we could instantly switch back and forth and A|B|A listen
- Some DACs I had for days and others for only a few hours!
- I am not bought into, "...how the artists intended it..." I do not care too much about measurements. I have firsthand seen debates between artists and engineers occur on mixes to the effect of, "...it sounds best under x! But, we should mix it this way as most people will listen with y..." Let me say this another way. I care about music that moves me emotionally. I have regularly smiled when I read statements about "...how the artists intended..." I suggest that these people speak to some artists on how the process works.
The system that was used is outlined below.
- Source: Roon Nucleus connected via either network or by USB (specified per DAC)
- DAC: Variable
- Pre-Amp: Boulder 3010
- Amp: Boulder 3060
- Speakers: Wilson Alexx V
- Cables: All cabling is Transparent Opus Gen 6 (power cords are all Gen 5)
Basis system:
dCS Vivaldi
- Connections:
- Ethernet connection to network
- Transparent Magnum Opus Gen 6 balanced interconnect *tuned
- Audition setup: Dealer loaned it to me
- Impressions
- Detail and resolution as good as I have ever heard
- Can be a bit harsh upper range vocals
- Wanted for more body - it can be somewhat thin
- Incredible ability to resolve complex transients
- Wanted for longer more natural decay - felt like it was 'just the facts' and absolutely no more
- Lacked some warmth
- Upper mid-range balanced
- GREAT on classical music, processed music and EDM
- Other: The dCS is highly dependent on the Upsampler and DAC variables that are user set. There is a filter on the Upsampler, an Upsampler output formal (DSD etc), a DAC filter and a DAC map. And, they all affect the sound.
Lampizator Horizon
- Connections:
- FTA USB from Roon Nuc
- Transparent Opus Gen 6 balanced interconnect *not tuned
- Audition setup: Sent for audition
- Impressions
- Wow! The holographic soundstage is amazing!
- Density!
- Decay
- Air and space - instruments are there!
- Not a quick and resolving as the dCS but so so musical
- Other: The Horizon changed sound signature in the days I had with it more-so than solid-state gear I am used to. I was urged by Steve W to be patient but I was not. I have since wondered as the person I sent mine to indicated that once broken in it was incredible. I do not doubt it. That first night I plugged it in it was like nothing I have heard before.
Nagra HD X
- Connections:
- Source was replaced by an Ideon Absolute Stream and Clock
- USB to DAC (dealer brought top end Audio Quest)
- Audio Quest Dragon balanced interconnect to pre-amp
- Audition setup: Dealer onsite audition for 2 hours
- Impressions
- Smoother than dCS
- Nice linearity and body with classical and rock
- Struggled v dCS on some quick transients
- Less musical than dCS on highly processed music and EDM
- Mid-range focused v dCS
- Other: I could have happily gone with this DAC
Infigo Method 4
- Connections:
- Bespoke streamer brought by Infigo Audio
- USB to DAC
- Transparent Opus Gen 6 balanced interconnect to pre-amp *not tuned
- Audition setup: Infigo Principle brought to my home for a couple hours
- Impressions
- Warm - almost tube warm
- Soundstage was similar to dCS
- Struggled v dCS on some quick transients
- On some dance tracks such as Senorita (Shawn Mendes and Camilla Cabello) it was get up and dance engaging.
- Seemed to really shine with upper midrange centric tracks
- Other: The Principal of Infigo is one of the nicer and most intellectually curious people I have met in audio
Wadax Reference
- Connections:
- Wadax Reference Server
- Specific optical cable between server and DAC
- Audio Quest Niagra 7000 power conditioner
- Ethernet to server via Audio Quest Diamond
- Audio Quest Dragon balanced interconnect to pre-amp
- Audition setup: Dealer visit for 2 hours
- Impressions
- Linear
- Smooth
- Noise floor higher than dCS
- Very musical
- Server adjustments - Gain etc made massive changes in sound and were necessary
- Soundstage very similar to dCS
- No matter what music thrown at it it sounded great
- Very balanced
- Handled transients as well as dCS
- Other:
- I do not understand the Wadax haters. It is a damn impressive DAC. One might argue value but, at least in my system to my ears, it was a wow.
- I suspect that the server is required for the sound on this one.
Aries Cerat Kassandra Ref
- Connections:
- $5 computer USB from Nuc
- Transparent Opus Gen 6 balanced interconnect to pre-amp *not tuned
- Audition setup: Very kind visit from Robert Do
- Impressions
- Imagine solid state with a hint of tubes
- Linear and quick
- Noise floor higher than dCS
- A tick muddled on quick transients
- Slightly less musical on processed and EDM than dCS
- Other:
- Near entry level DAC for Aries Cerat that held up to the dCS flagship. Wish I had more time with it!
- Changed the power cord from Transparent Opus to Inakustik reference silver and it resolved as well as the dCS
SW1X DAC 1
- Connections:
- Coax from my upstairs bedroom subwoofer went from Upsampler as passthrough to DAC
- Audition setup: Sent from distributor for audition
- Impressions
- Wonderful tube sound
- Did not seem to have the soundstage like the Lampi
- Struggled on transient and complex sections compared to the dCS
- Very smooth
- Lower mid balanced
- Other:
- This was a somewhat unfair comparison. The cable was an Amazon Basics subwoofer coax passing through other components.
- I do not feel entirely comfortable with this set of notes given the cobbled together setup
MSB Select II
- Connections:
- Roon Nuc -> Shunyata Omega USB t-> ProISL
- Transparent Opus Gen 6 balanced interconnect to pre-amp *not tuned
- Audition setup: Purchased used for demo
- Impressions
- Body and density!
- Balanced across the spectrum
- Linearity to match anything
- Has every bit the detail of the dCS
- No harshness anywhere
- Has a width and depth of soundstage that is great
- Want for a tick more dynamic slam
- One of only two DACs that matched or bettered the dCS on all tracks played
- Other:
Summary: I only auditioned one DAC that I just did not like. Out of respect I have omitted it. I could have lived with any of the above DACs. The MSB and the Wadax were uniquely great at everything I played. The dCS is awesome with processed music and classical. The Lampizator continues to be curious to me as it was literally magical that first day! I am admittedly impatient and a bit compulsive - I maybe cut the cord too quick. I was close to buying the Wadax but the MSB was so very good that I just could not rationalize the price delta. In other words, price was somewhat always in the mix. But, I was ready to buy any of these and if the Wadax had been noticeably stronger I would have bought it. I wish I could have A|B'd it to the MSB and even the Lampi. But, when I heard the MSB I felt it sounded as good from memory as anything and that was it.
