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.

Thank you for your response-  very very helpful.  I kind of thought Bricasti would likely be the way to go- and have been debating between an M3 and an M1 SE (assuming I could find a used one and within my budget).  A straight M1 would probably be in range but then wouldn't an M3 with MDx be a somewhat better sounding DAC?
What I had not realized is that a Nucleus vs a Mac Mini would make such a difference- I simply assumed the Nucleus, while a more tailored solution, would still have the same characteristics of using a computer.  Also, I thought that once a Dac with a network card was in place + using an ethernet connection then the Mac Mini (or similar) issues would be taken out of the loop (I guess I was thinking mostly of Usb "noise").
As someone posted already getting digital right is as complicated as analog.  I am just starting to get up to speed all the intricacies and have quite a way to go.

 

I know it doesn't seem obvious a server would make that much difference.  Part of it is the quality of the parts.  Part of it is the higher processing power and parts selected specifically for audio performance.  Servers make a difference more than most people think.  Think of it this way.  I have had quite a few people order Nucleus's while being skeptical if they actually make a difference.  I have never had one returned on my 30 day return policy.  

The M1 SE is going to be a bit more detailed than the M3.  Soundstage in both cases is huge.  I have not sold an M1 and have not heard it.   Bricasti said few people ever buy it vs. the M1 SE so I ordered and M1 SE and M3 for my initial samples.  The M1 SE is quite a step up from the M3 though the M3 is quite competitive in its price tier.  

@verdantaudio   I'm curious how you attribute an aspect like soundstage depth to a DAC, in context of the uniqueness of various systems, the rooms these systems are in, the listener positions, and the use / lack of use of room treatment (for the purchasing party)?

I'm not challenging...just trying to understand and learn.

Thanks. - David.

@david_ten

am sure scott will answer, but my 2 cents, my own process:

- have my system set up ideally in my room (see my system page for pics)

- have my standard ’reference’ dac in place, know how music i know well sounds, how the soundstage is presented, in terms of size (width, height, depth) and separation / layering / relative distance of voices/instruments etc

- swap in new dac being evaluated, adjust for correct (same) volume level, listen and perceive how the sonic ’image’ is presented differently, if at all (don’t change anything else, even cabling)

- btw - having a well selected playlist of familiar music helps alot in this...

hope that helps

@david_ten I have been lucky to have heard dozens of these premium DACs with a variety of speakers in my home and in many friends and customers homes.  I am lucky.  

On a relative basis, certain brands/DACs exhibit certain properties.  In any system, I would expect a Rockna DAC to sound wider and flatter than Chord DAC which would be narrower but much deeper.  There are many ways to compensate but if everything is held equal, I would expect this relatively to be true.  
 

you are right though.  A combination of room treatments or different speakers and system components could achieve different results.  If depth of soundstage is a concern, MBL or Raidho speakers would have a bigger impact than a Bricasti DAC.  But, that necessitates rethinking amplification and a variety of things.  And it is true that a Rockna DAC in a system with Raidho speakers would probably sound deeper than a Chord or Bricasti DAC in a system with Magico speakers.  but that isn’t the exercise in this case.  The only variable proposed was DAC.

this does raise  an important point and something everyone should be reminded of.  The particular results in this thread are from a system that is intentionally held constant to provide relative characteristics.  And I think that is the key here, results are relative.  When you change a variable (speaker, amp, etc…), you do need to think through the implications.
