DH Labs - Shunyata Cable Comparison


My system for Background:

Harbeth C7ES=XD Speakers

Accuphase P4600 Power Amp

Aurender N20 Streamer

MSB Discrete DAC

This is a new system purchased over the last 6 months. While the system settled in I purchased Blue Jeans cables: Ethernet, Digital XLR, Analog XLR Interconnects, Digital Coax for the Clock connection between the Streamer and DAC and Speaker cables.

Later I upgraded the Ethernet cable with the DH Labs Reunion and the DH Labs Digital XLR. Both these cables provide a noticeable upgrade that I really liked so I put DH on my further upgrade list.I was also interested in the new Gamma line from Shunyata.

The most convenient way to audition cables at home for me is to use The Cable Company's Lending Library. You have 10 days to 2 weeks to evaluate whatever you want to hear. So I borrowed:

DH Labs Air Matrix XLR Interconnects

Shunyata Gamma XLR Interconnects

AND

DH Labs Q10 Signature Speaker Cables

Shunyata Gamma Speaker Cables

I really liked the DH Labs Air Matrix Cryo. It offered a very open, airy and clear presentation somewhat laid back and with a nice a soundstage depth. It was also excellent with voices. The Gammas were also very nice but I found them less open and airy like someone put a lid on the sound.

Leaving the Air Matrix in the system I replaced the Blue Jeans Speaker Cables with the DH Labs Q10s. My quick initial response was that I lost some of the air and the soundstage was not as big so I quickly replaced them with the Gammas which were even less airy and the soundstage did not have the same depth. At this point I was disappointed that neither apparently offered an upgrade to the Blue Jeans.

Thinking about this overnight I felt I really made snap decisions about both cables and I should give each a more extended and varied listen. So the next day I started again with the Q10s. I listened this time for many hours and with a variety of tracks. The sound started to grow on me. I realized that the apparent loss of air was just the Q10s delivering a cleaner high end. Once I became accustomed to this sound I preferred it to the Blue Jeans.

The next day I replaced the Q10s with the Gammas. Again after extended and varied listening I started to notice the strengths of the Gammas: A very refined high end and a deep and impactful bass.I actually started to prefer their sound characteristics over the Q10s even though they were not as open and the soundstage depth was not as deep.

The next day while continuing to listen to the Gammas I realized I missed the extended airy high end and deeper soundstage of the Q10s. Their highs were not as refined but the overall presentation was much more lively and large while the Gammas were refined, controlled and impactful but less lively. As a test I replaced the DH Labs Air Matrix XLRs with the Gammas. The combination of all Gamma was too dark.

I then put the Q10s back in the system and immediately reveled in their larger open and airy soundstage.I then decided to try the Gamma XLRs with he Q10 cables. That was a decent combination that was better than all Gamma or Air Matrix and Gamma but still not as open and lively as the all DH Labs combo.

So my plan is to purchase both DH Labs cables.

I've also learned that I should not quickly dismiss a component. Sometimes the initial difference or characteristic is not a true measure of its overall performance. I really need to listen for several hours and use a wide variety of music to clearly get an understanding of the sound signature of these cables. When I did that the sound of each started to grow on me. My snap judgments caused me confusion and unnecessary retesting.

BTW my Accuphase Amp has a Speaker A/B Selection switch. It has two sets of speaker terminals so I was able to have the Gamma with Banana plugs connected to one set of terminals and the speakers and the Q10s with Spades connected to the other terminals and speakers. This allowed for more convenient switching making the comparison somewhat easier but it was still an adventure.

Next I plan to borrow the DH Labs Coax Interconnects for the Clock and their higher end Digital XLRs. I'll probably try a few of their better power cables at different price points. In my experience DH Labs products really punch above their weight and offer really good value. And I also highly recommend The Cable Company if you want to audition a variety of cables or power conditioners at home.

One correction from my post.

I don’t mean to suggest that simply being young means that people haven’t heard - or aren’t interested in - listening carefully (although it certainly sounds that way on re-reading it). I’m saying there are fewer opportunities to hear live music that isn’t amplified in some way, in a way that was never an issue 50 or 60 years ago, when I was in high school. You’d go to a friend’s house and he had piano practice, or tuba lessons (back then, I used to feel sorry for buddies who had to learn to play tuba). But many of us from that era knew one or two people whose parents forced them into music lessons, so sometimes you heard them playing piano from 10 feet away. We got a LOT more exposure to acoustic music and instruments (there wasn’t much else back then!) than nowadays.

I also respect megabyte’s comments, because he’s actually listened. He says he just didn’t hear it in the cables, and I believe him. I can respect anyone who has done the work and THEN says, I couldn’t hear it, but most of the time, on these forums, that is not the case. (Just ask someone challenging you about cables, what type of music they listen to, and it seems that it is rarely acoustic music (which includes rock!).People just seem to prefer to believe the entire field is snake oil (and that we can’t hear, which I find hilarious since I’m old and yet, I can still hear overtone structures of, say, pianos or harpsichords) , and those same people make disparaging comments, but again, without ANY experience. I have ZERO respect for those comments and the people behind those comments (but only on this subject).

My husband told me last year that he had no idea what ’dynamic range’ was until I took him to the symphony and we heard Gershwin’s Rhapsody in Blue, and another weekend, Stravinsky’s Firebird. After that, he got it when I explained that, in audio, some equipment will play only the medium-loud notes, but when it comes to softer notes (Piano to pianissimo), or even the big crescendos, the equipment can’t deliver.

And actually, classical music wasn’t something he’d been exposed to all that much. Once we started going to the symphony, that changed, and I would point out certain things, like staccato or legato (after the symphony, not during it!). Now he understands what I mean when I say I want to hear a piece of music at the symphony, and he’s begun to enjoy going to it.

The audiophile stuff (e.g. imaging, soundstage, specificity of image) are not things he’ll get, since he doesn’t listen to music that often at home, but the musical part of music? He can appreciate that, and appreciates our home system more. And that’s good enough for me.

And, finally, an anecdote about cables.

Back in 2013, when I bought Nordost’s Tyr 2 inteconnect and upgraded the speaker cable, a friend of mine came through on his way to Boston. He’s a conductor for a major symphony orchestra (not saying which one, because I’m not dragging him into it). He listened to my system and then turned to me - unprompted - and said that the hadn’t heard this much harmonic information from my system prior to now. That was strictly the Nordost interconnects and Shunyata’s speaker cable. He heard the improvements clearly, even though he had no idea what had changed, and he hadn’t heard my system in year or two. But he’s got very well-trained ears, I think we can agree.

So, a lot of this is down to experience and knowledge. Just like in any field where someone is required to know a subject in depth before passing judgement on it.

OP: teach me something here. Don't your electronics hugely overmatch your little Harbeths? You did call this a "bakground" system -- does this mean you also maintain a separate "monster" system?

@hickamore 

 

I didn’t say it was a background system. I said as background I am specifying the system. 
 

The Harbeths are certainly not overmatched. It is recommended that you give them as much power as possible. They are neutral, very smooth in the upper frequencies and the most life like in the presentation of acoustic and vocal music. Plus they deliver excellent low end response as they are only down 3db at 45 hz. I sold my two REL subs. Also  my room is not large and I sit about 8 feet from the speakers 

@jfrmusic 

I enjoyed reading your findings and thanks for posting. DH Labs offers good performance at reasonable prices. As I recall, DH Labs was my first aftermarket power cord about 20 years ago. I really enjoyed building my own power cables with wattgate plugs. DH Labs used to sell bulk power cable for DIY’s, not sure if they still do. They were eventually replaced by Purist Audio Musaeus Loom :-) 

Just ignore the cable detractors and enjoy the music and your journey.
