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.

yyzsantabarbara - all of the DACs tested produced what sounded like a clear bass line.  It was only in comparison that I realized that it could be better than what I was hearing.

I am not saying that either your Gustard or Benchmark can't do this.  Unless I was able to do the test side-by-side with these, I can't be certain.  I merely am saying I was surprised how much more info was available and wasn't showing up, even among these rather expensive units.  The Rockna Wavedream Signature executed this better than any of the units, by far and it was illuminating.

Regarding performance, my M3 does not have the network card. The M1 SE has the network card.

That’s a significant data point, and could go a long way to explaining differences in sonic characteristics between the M3 and M1 SE. It’s a shame they weren’t comparably equipped.


yes - that point jumped out at me too... i don’t know the bricasti units... can the network card be swapped from m1 to m3 and then run comparison the other way? that may isolate the beneficial effect of the card on sq of the 2 units

No swapping of cards.  

For the two units during the testing, I strictly used the 2Go/2Yu as the input.  
I did test the M1 SE separately with the two inputs and found I like Ethernet slightly better.  Theoretically the network card could be much better on the M3.  I am making an assumption that it had a similar benefit to both.

@verdantaudio, thanks for the info. Great stuff.

Yesterday I updated my system page and today I added this:

Speakers are 6 feet apart center-to-center and the back of the speakers are 4 feet from the front wall and about 2.5 feet from the side walls. Listening position is 6 feet back and speakers are on GAIA I's and slightly toed in to point over my shoulders. GIK bass traps are on the walls, corners and ceiling, which resulted in a big improvement in soundstage.

What I'm really missing is depth and space around instruments and depth of the soundstage.  Maybe in my price range the space between instruments and instrument height is a big ask?  I will admit that much of the music I listen to is not audiophile quality but a good amount is.
