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.

Thanks @ddafoe for the info. As my dealer showed me it's easier and much more cost effective (although not as much fun) to change power cords and get what you are striving for than changing dacs. Yes dacs sound a bit different but they are all sounding so good and by changing an interconnect or ac cord you can change the sound even more. Just my own experience. 

I have promised a few more reviews here as some new devices have come in and one specifically is the Musical Fidelity M3s CD.  This is a CD player with SPDIF, USB and TOSLINK inputs and lists for $1599.  I bought it before AXPONA in 2019 for CD Transport for that show and literally had never listened to the DAC. 

On In a Sentimental Mood, sparkle in the top end of the piano is great.  Separation is good within the drum roll, not elite.  It feels like this unit has a slight emphasis on the midrange as bass is slightly recessive and the cymbals in the right speaker are forward.  Balance is different but it delivers a very musical and enjoyable performance.  

In Be Still My Beating Heart, again slight absence of bass and resulting image seems short and moderately wide.  Certainly wider than the Hugo 2 but with less depth in the central image.  Noise floor is not as quiet. 

Effects are prominent on Liberty. Not a touch of sibilance.  

Duende had good, not great detail in the bass region. Treble separation was very good.  

With Berg, there was a slight massing of strings which might be worse on a larger orchestral recording but it is very enjoyable.  

PRaT is the signature.  Extraordinary mids with a punchy mid-bass but without any excessive treble and slightly recessive bass.  This may have been designed to compliment the slight brightness that one gets with MF integrated amp.  

Like the Questyle, this unit is awesome for the money.  If you told me it was twice the price I would not be shocked.  Anyone looking for a quality DAC in the sub $2K range would be wise to consider this unit even if you never plan to open the CD tray.  It will be especially nice in a system that is a touch bright at the top end or excessively bass heavy.  

This unit sat in storage for almost 2 years and bluntly, I am disappointed that I haven't spent more time with it.  It is striking a nice balance between detail and soundstage.  Biggest issues I see are size and lack of XLRs which is not that uncommon in this price tier.  

 

verdantaudio,

I've followed this thread, because I currently have a Chord Dave DAC and I'm looking for the next level DAC without spending $20K. I've read that the Chord Dave can be analytical and thin, but compared to the PS Audio Directstream, Bricasti M1, Jeff Rowland Aeris, and Rockna I don't hear it. I've had all of the aforementioned DAC in my system and I prefer the Dave. Based on my experience it seems DACs are like all audio components...the system/personal preference is the most significant factor determining what DAC is "best".

@verdantaudio 

I currently have Bryston Mini-T speakers (with Yamaha PC2002 power amp) and was thinking of moving towards a fully Bryston system...but came across your post commenting about microdynamics.

Based on your experience, it it worth pursuing building a system around the Mini-T's if i want Microdymics?  What i mean to say, is it the Bryston speakers or amplifiers that are the limiting factor for microdynamics?


The microdynamics are a huge part of what I have have been focusing on in this thread.  It is the fine details.  Subtleties in the way a drum roll comes together, speedy bass notes, sound effects, separation of notes in bells and piano.  These little things are inherently the difference between very good and extraordinary and they do add up.  

That being said, you do need to have a system capable of delivering those microdynamics to you.  You need a resolving enough amplifier and speakers that are sufficiently detailed.  Years ago I did a demo of a bunch of stand-mount speakers in the $1000 to $2000 range and a couple floor standers.  One test track I used was Don't Give Up by Peter Gabriel off of Secret World Live.  What I discovered in that session was that multiple speakers were simply not capable reproducing the fine details of things like crowd noise in certain parts of that song.  It was an entirely Bryston system with a speaker switch so it wasn't the amp or DAC, the only change was the speakers.  You can get the most detailed DAC in the world and if your speakers are your systems bottleneck you will not benefit.  

Regarding imaging, separation of instruments and soundstage, all of these things vary wildly from dac to dac and there is no objective "this is how it should sound" benchmark to know if your DAC is doing well.  The closest you can come is Q sound recordings but those are problematic in the opposite direction in that virtually any DAC and system should be able to make those sound incredible.  


@fai_v     I have never heard the mini-Ts and cannot speak about there ability to deliver micro-dynamics. That said, I am biased heavily against standard wood box speakers when it comes to production of fine details. My bias shows up in my own designs and the lead products I offer. My speaker cabinets are made from either Carbon Fiber or Fiberglass and the two lines I most focus on are Vivid (fiberglass) and Wilson Benesch (carbon fiber) as I understand why they are so good. It makes sense to me. I may not be best person to ask because of my bias.

That being said, Bryston hardware (amps and preamps) will not be a bottleneck in your system. It is VERY good electronics. I have not heard their DAC personally but I know it is supposed to be very good. Key is system matching. I would demo speakers you are interested in in home or on Bryston gear if you can. If not, work with someone who know the brands really well.
