DAC Shootout Starts This Weekend


Okay...in another thread I promised to do a side-by-side evaluation of the Audiobyte HydraVox/Zap vs the Rockna Wavelight. Due to the astonishing incompetence of DHL this has been delayed. At the moment, I have a plethora of DACs here and am going to do a broader comparison.

I am going to do a compare of the Rockna Wavelight, Rockna Wavedream Signature, Audiobyte HydraVox/Zap, Chord Hugo 2, Chord Hugo TT2, Bricasti M3, Bricasti M1 Special Edition, Weiss 501 and the internal DAC card for an AVM A 5.2 Integrated amp as a baseline.

For sake of consistency, I am going to use that same AVM integrated amp driving Vivid Kaya 45s. I may branch out and do some listening on other speakers (Verdant Nightshade of Blackthorn and/or Wilson Benesch Vertexes) but want to use the Vivids for every compare as they are the fullest range speakers I have here. For sake of consistency I will use a Chord 2Go/2Yu connected via an Audioquest Diamond USB as a renderer. The only exception is the Hugo 2 which has a 2Go directly attached to it. I will use a Roon Nucleus+ as a server in all cases.

My plan is to use the same five songs on every DAC; In a Sentimental Mood from Duke Ellington and John Coltrane, Be Still My Beating Heart from Sting, Liberty from Anette Askvik, Duende from Bozzio Levin Stevens and Part 1 of Mozart String Quartet No 14 in G Major from the Alban Berg Quartet. The intent is to touch on different music types without going crazy.

I will take extensive notes on each listening session and write up a POV on the strengths of each unit. I am going to start this this Friday/Saturday and will be writing things up over the next month or so. If you have thoughts, comments or requests, I will be happy to try and accommodate. The one thing I am not going to do is make the list of songs longer as that has an exponential impact on this and make everything much harder. If and when other DACs come in on trade I may add to the list through time.

Couple of updates.  

I have done some testing with cables.  The AQ Diamond is very good.  I swapped in a Clarus Crimson and think it was a pleasant switch depending on the speakers and is a very good substitute.  if you have issues with box on AQ stuff fitting, this is a brilliant substitute.

In some cases, I reported a bit of bass emphasis with some DACs.  Swapping speaker cables, I think that was the AQ Robin Hoods, not the DACs.  It is definitely a more bass heavy cable which is probably why I like it with my stand mounts.

Finally, I have done some additional testing with different servers.  I have an Antipodes K40 here (and an open box) along with my sample Nucleus+, a traded in Nucleus and a Wavedream NET that was just traded in with a Wavedream Signature DAC.    

The Nucleus+ and Nucleus exhibited no difference as standalone servers.  I do think there was a small improvement with the Nucleus+ when they were connected via USB and the Roon unit was used as server and renderer but it was small enough that I am not certain and it could be my internal bias.  

The Antipodes K40 as a server used either with the Weiss directly via ethernet or with the Chord (2Go/2Yu) renderer is significantly better.  It should be at 4 to 6x the cost of the nucleus but everything is clearer and cleaner.  Effects, especially in Liberty, clustered notes like the opening of Duende or bells in Be Still My Beating Heart are just clearer. 

The Wavedream NET as a Server vs the Antipodes were a push when feeding the 2Go/2Yu.  Feeding the Wavedream Signature takes this DAC to a totally different level.  The loss of that last, tiny bit of jitter is just mind boggling.  I am using an Audioquest Dragon 48 HDMI to connect them.  The idea is that the clock is perfectly synchronized between the two devices and that is completely obvious.  

 
@verdantaudio,

case in point: that’s why reclockers like the InnuOS Phoenix actually have a value. Even better is the scenario where you can connect server and DAC via USB with a 10m OCXO or rubidium clock optimising the DAC clock. Since the DAC on asynchronous USB actually slaves the server, not only do you get a reclocked USB link but also the highest accuracy clock for the actual d to a conversion in the DAC. It’s why Esoteric and DCM offer dedicated clocks in their stacks
@Chorus  this really is a matter of taste, system and music preference which is best.  
For me, the Rockna Wavedream Signature, Vu Jade, Weiss, Bricasti M1 SE and Audiobyte were my favorites in roughly that order.  My bias is toward detail because my gear and speakers are very musical and throw a big soundstage.   If I had different gear, my order could change.  

For perspective, I just had someone trade in the Rockna because what I love about it, they didn’t like.  They are going with a new tube DAC from Gordon Rankin.  
@antigrunge2. I have not played with an external clock personally but am pretty certain I need to get an Antipodes Clock in to understand its impact.  
No question clocking matters.  
To dankef,
I’ve owned both the Morpheus and Bricasti M3.
In comparison to each other, the Morpheus is slightly soft while the Bricasti is a bit more incisive.
I enjoy both DACs and a choice would depend on the rest of your system and what you want to achieve.
Also, consider that the M3 is twice the price of the Sonnet.
