First impressions of new MH-DA006, Musetec flagship

@catastrofe Technically, I don't see anything special with usb input on Laiv. Likely I'll try Laiv in main system this week, need to get up to around 200 hours burn in on this unit, this will continue to be over usb input. I2S will come later when Gaia has sufficient hours. Your take on Laiv vs older msb interesting, I've commonly heard msb described as more on analytical side.

006 COMES ALIVE! What do I mean by this? So, now at around 300 hours last night's listening session marked a transition point where 006 finally opening up. Firstly, tonally top end opened up, no longer even a hint of darkness/closed in sound, I now hear this as a former veil over the presentation, new level of transparency gained over any previous dac. Secondly, there was an important and profound change in the dynamic envelope. Specifically, I'm speaking of micro dynamics, the fine gradations of dynamics range we hear with non amplified voices and musicians, This means breath with voice and wind instruments, touch with stringed instruments, Get this right and the illusion of live performers in listening room becomes greatly heightened. Add this to the more natural timbre of 006 and you have what some describe as texture, I'd also describe it as expression, 006 has both in spades.

I'll go into a bit of depth here on this issue of compression. Certainly, I hear much about compression on recordings, not so much with playback. And I hear this described mostly as macro dynamic compression. While this is certainly a concern, the micro form is what makes recordings sound flat and boring. Maximizing micro dynamics in one's system seems to me perhaps the single most important aspect in delivering this sensation of live performers in room. Many describe highly resolving systems that only sound good with higher quality recordings. When you maximize micro dynamics in your system far more recordings become palatable  and/or involving. 006 has greatly increased my involvement with virtually every recording I've played thus far. And no homogenization like one may hear with lower levels of resolution, every recording is presented with it's own unique sound signature.

So, now we have this heightened level of expression in addition to extraordinary traits of this unit mentioned in prior posts. End result is best digital presentation I've yet heard, right up there with the best analog sources I've had the pleasure to hear.

I should also note there was a transition period running somewhere between 225-nearly 300 hours where presentation pretty poor. Unit opened up on top, slight veiling disappeared and dynamics not fully developed. Presentation I'd most liken it to was when burning in rhodium connectors, somewhat hard, bright on top, thudding one note bass. Compared to the previously somewhat polite, forgiving nature of unit in earlier hours this was quite a slap in the face. Luckily I burned through silently during vast majority of this transition. Based on many previous burn in regimes I'm expecting a more stable floor with incremental improvements, especially in dynamic envelope. Transients should balance out between attack and decay for an even more relaxed presentation.

@sns, by "stellar" I meant that LAiV's USB implementation, being galvanically isolated, is probably as good an implementation as can be found. I tried an iFi iPurifier 3 in the chain (Roon core > USB > LAiV) just for grins, and there was no improvement.

I also found the LAiV USB input to be on par with its I2S input, using a Gustard U-18. Switching between internal and external clocking on the LAiV yielded no noticeable difference either. Of course, that's a function of the clock quality in both the LAiV and the U-18.

In my 40+ years in this hobby, I've never heard MSB being described as analytical. That has not been my experience, having owned both the Analog DAC, and prior to that, the Signature DAC IV.

Looking forward to your additional thoughts once you start listening to the LAiV. 

@catastrofe In regard to usb I was specifically comparing Laiv to 006, my take based on manufacturer info is 006 takes more pains. In any case, I didn't hear any obvious issues using Laiv usb. Have Gaia cooking with Laiv via I2S at the moment in a small desktop system, can hear a difference between slaving to Gaia clock vs. using Harmony internal clock, not judging quality at this point.

Now that's some Dac.Enjoy....

After cooking for half a day, Harmony slaved to Gaia clock  via I2S far superior to usb directly out of computer, this is to be expected as Gaia acting as 'buffer' from noisy general purpose computer, clocking aspect playing large role as well\. Comparing this I2S chain vs optimized usb in main system will be much more formidable 'opponent'.
