@sns your USB implementation looks pretty sweet, some nice gear there, I wouldn't be in any hurry either. By contrast I need to up my cable and PS game a little and agree the U18 whilst solid is far from the last word in I2S, the Audio-Gd DDCs with regenerated power on the order hand, they're pretty special.

@kereru Forgot about Audio-gd, the DI-24SE very interesting, and price point very nice. |
I picked up a Denafrips Hermes DDC about two weeks ago and it's working quite well with the Laiv Harmony. The Hermes now receives a coax input from a TEAC 701T CD transport and a usb input from a Bluesound Node 130. The Harmony receives an I2S input from the Hermes. Previously the Harmony received coax from the transport and usb from the node. The improvement in CD sound is primarily spatial, with a slightly deeper and wider soundstage, and also better bass extension and definition. Without resorting to a lot of "reviewer speak", I think CDs with the Hermes in place just sound more enjoyable. The really big bump up in audio performance comes with streaming from the Bluesound Node: everything sounds better from this very modest streamer with the Hermes in the signal path. Bass is deep, full, and tight; soundstage is precise with lots of air around the musical sources; and the overall presentation is very natural and smooth. I'm very happy with the Hermes and the Harmony is too. |
@smweber2 i had a similar experience when I added a Hermes between my streaming source (MacBook pro) and my Pontus II. It made a noticeable difference in all the same areas you mentioned as well as transient response. |
Ongoing experiments with Laiv vs Musetec 006. I've been listening to Musetec in main system for several weeks, burn in now up to 300 hours, probably a good 30 hours of that serious, undivided listening sessions. In the meantime I had Harmony burning in on second rig and purchased the already planned for Denafrips Gaia, so further burn in with Gaia via I2S slaved to Gaia clock, just over 100 hours on this setup, so around 250 hours total on Harmony.
Harmony via optimized usb, won't go into great detail here, but usb optimized over many years, many devices, final solution has been optical conversion via Sonore devices. So, upon initial listening sessions thought Harmony via usb pretty nice, prior review reflects that. Over several weeks of listening and burn in Musetec furthered it's advantage over Laiv, both dacs via usb, this based on my memory of how Harmony sounded in main rig. So finally got back to Harmony in main rig, first via usb. Via usb Harmony sounded rather flat in comparison to the Musetec which had improved quite a bit over the weeks of burn in and listening. Sound stage and imaging decent, devoid of comparison to 006 most would probably find it to be quite nice, but it simply didn't have the image density or the ability to escape front baffle of loudspeakers, just rather flat or meh. Tonality or tonal balance also off, lack of air on top, I'd say it was rather dark sounding. Transparency also took a hit, veiled and opaque compared to 006. Both macro and micro dynamics also not up to par, simply somewhat flat and lifeless. While my initial listening to Harmony via usb had been much more positive, the evolving sound of 006 had now made the Harmony a meh listen. Rather like midfi, not very interesting or involving, clear cut loser to 006. I should add this all via NOS mode, since my initial listening in OS mode found it inferior to NOS mode by quite a large margin.
So, now Harmony with Gaia via I2S, clock slaved to Gaia. I don't usually go for hyperbole, but just WOW! Immediately could hear a far more expansive sound stage and the image density just floored me. Gone was the dark presentation, now airy and open at top, bass was also far more articulate and impactful. And talk about black backgrounds, I thought 006 excelled here, well Harmony with Gaia presents an even more ethereal experience, relief from a background plane which allows lowest level details to stand out, I more clearly heard hard to make out words in vocals, and background instruments, this above and beyond what I thought was excellence with 006. Complex passages and/or recordings with many performers now much more fully realized and organized/differentiated. And transparency certainly a huge notch up, no more veils or opaqueness, performers in room quality heightened over the already impressive 006.
All in all I was not quite expecting this, I was expecting something along the lines of subtle differences between this and 006. As it stands today, if I were to only have one dac it would be Laiv/Gaia vs 006, this combo stands head and shoulders above 006. A more analog like presentation presumably due to ladder dac's inherent superiority via chip dacs. And then you add to this all the above mentioned advantages over 006, really not much of a contest here. Now, I'm not entirely convinced yet, 006 more development via more burn in, 006 will be partnered with Gaia via I2S. Not sure what to expect, but usb in 006 is more technically developed in 006 vs Harmony, Harmony usb pretty ordinary. In this case 006 may not benefit as much from I2S as the Harmony. Also, I've long heard I2S is preferred choice for ladder dacs in general, providing precise timing for massive banks of resistors is necessary for best performance. In any case I'm absolutely convinced Harmony's potential will not be heard via usb and/or nothing less than the best external clock via I2S. I'll offer the external clock needs to OXCO, not TXCO or femtoclock, and the internal clock in Harmony is femto. While clocks within dacs should have a theoretical advantage being closer to I2S path, a far superior external clock will better that.
I should add, this review is as much about the Gaia as the Harmony, the Gaia is a special piece. And to think present setup far from optimized, presently using relatively cheap, $70 copper I2S cable (not hdmi cable, I2S cables only have 9 pins wired, all other pins video related), I have Tubulus Concentus pure silver I2S on order. Also using relatively cheap Pangea 14SE power cable, already in midst of upgrade here. Finally, using stock feet on custom build baltic birch platform, will likely use Stillpoints on a different platform eventually, Point here is I suspect further improvements with Harmony/Gaia can be achieved.
For a more contextual or larger view, $2700 for Harmony, $1800 for Gaia makes for a $4500 total expenditure, add to this a quality power and I2S cable. The Tubulus is $700, my diy power cables are a relative bargain, but I'll assume at least $1k to match, now we're at aprox. $6200. And I could add the cost of Stillpoints. My question than becomes at what point do I still call the Harmony a bargain, could I do better with something like the T&A 200 or used Mola Mola Tamlbaqui? Is I2S necessary with every dac in order to extract max performance? |
