Great review!! Well you know my thoughts. They align with the reviewer.

That’s cool. I found this paragraph very interesting as I found the same thing. I settled on 4fs. I just went back to native and yup, I think I prefer 4fs. 8fs was a little too much of a good thing for my ears. I’ll try 16fs as Wojciech suggests since I really never did.

“The Esoteric player offers user digital filters to choose from as well as a choice of the type of upsampling. I listened to it for a long time with the PCM signal upsampled to DSD, but I gave it up. Converting PCM to DSD in this case results in a warmer, darker sound, which, however, does not have the dynamics of the original, nor its resolution. So in the end I listened to music with PCM max upsampling (16 fs). For PCM I chose M3 filter and for DSD the FLT2 one.”

I run my Grandioso transport at 88.2 upsampling when playing CD's....dispensed with any experimentation on that, just accept it for what it is. Obviously, when playing SACD's it's native DSD.

Can stretch both, but saving some money is also fine.

Bought last year already a K1, but the seller turned out to be a scammer (through Hifi Shark, so beware). Luckily, in the end I got all my money back, thanks to my lawyer.

Thanks

So much of that going on with the used market right now. It’s really annoying.

The historically speaking there wasn’t always a major difference between the K1 and K3. But with the XD series, there is a significant difference between the K-01XD and K-03XD. I believe the K-01XD carries triple the number of delta-sigma chips over the K-03XD. Sonically, there is greater layering and a smoother presentation with the K-01XD. That being said, the K-03XD is a super performer at $14k and it’s the product that got me hooked.

Thanks a lot Mike. I'll have to try the oversampling and filters with the N-01XD.

As of now I find the sound of the N-01XD without oversampling (streaming from a Synology NAS and using the Esoteric app) + Cybershaft OP21A connected by RCA cables to the Devialet is truly excellent but currently still a bit being what I am getting streaming using Raat from the Mojo Audio EVO linux music server to the Devialet, but I suspect that this result may be impacted by the early burn-in of the Esoteric and by the mid range RCA cables I am currently using. I'll report again after my Chord Sarum T RCA cables are in place some time in February. I am currently using a Sigma V1 clock cable btwn the Cybershaft and the Esoteric and an Omega may be another way to improve.

Ideally I'd like to use Roon to stream from the Mojo Audio EVO through ethernet via the Melco S10 to the Esoteric but that will have to wait until the Roon certification of the Esoteric. I suspect that may be the best of both worlds in the end.

I was hoping to be able to stream from the Mojo in USB to the Esoteric also, but I haven't been able to find linux drivers for the Esoteric USB protocol.

Cheers,
Bernard

I’m still playing with the filters, but 4fs is my fave so far. I’m also anxiously waiting for Roon certification too. Even though I hate the bugginess of Roon and realize it may not be sonically the best, it will be the best option for the N-01XD. For now, I’m using the Lumin app and it’s running great.

Where do you place the K01XD regarding the SQ; closer to K03XD or closer to K1X. Thanks.

This will sound like a PC answer, but truly in between. If pressed, I would say closer to the K1X. In years past, the K-03 versions were quite close to the K-01 versions. With XD, that’s not the case. K-01XD is really a nice step up. HOWEVER, the K-03XD at $9000 less is really an incredible performer and if you never hear the K-01XD directly against it, ignorance will be bliss!

I’ve lived with this setting for a month. I’m back to my 4fs/M1 filter. I left DSD at FLT2.

Much happier with my settings.

It feels a bit more musical.

Either way the sound isn’t as defined/transparent as what I am getting streaming directly from the Mojo Deja Vu Evo through the Melco S10 to the Devialet, but using 4fs/M2 filter I get a more organic sound, a bit like playing vinyl instead of digital.

It’s significantly nicer with average records, including pretty much all pop/rock/country. Still highly defined but without any harshness.

With great recordings nothing seems to beat the internal dac of the Devialet it would seem.

For dsd files, in particular those from HDTT, I think I prefer the Esoteric, which makes sense since it supports DSD256 natively which the Devialet unfortunately doesn’t.

I didn't care for the M2 filter when I briefly tried it, but I will give it another shot.

I completely agree with you about the "vinyl sound" from the N-01xd. It really is true. It is the only dac I've ever owned that doesn't sound like digital at all.

What power cord are you using on it? I'm thinking I need to up my game on the PC feeding this beast.

Hi Marc,

Currently the power cord connecting the N-01XD to the Shunyata Everest is a Shunyata Sigma V1.

I may replace it by a Sigma V2 at a later stage. An Omega is tempting too, but I guess that replacing my Sigma V1 clock cable (connecting the N-01XD to the Cybershaft OP21A) by an Omega clock cable may result in higher benefits at a lower overall cost.

Bernard

Nice! I have a similar, yet slightly lower end set up.

I have the G-02x clock with a Sigma v1 clock cable, and a Denali 6000s v2 fed by the Sigma v1, and an older Alpha HC going to the N-01xd.

I have Alpha NR v2 cords feeding my amps (straight to the wall) and preamp (from Denali).

I really love what the NR v2 cords did for my system, and will likely get alpha or Sigma for the N-01xd.

It will take a while, because I just bought a new rack and a bunch of isolation stuff.

Very similar indeed. :-)

I got an Omega XC to connect the Everest to the wall, and the also Sigma V2 from Everest to the amps. This works very well indeed!

There is no end to this game, so playing it slow is certainly the right thing to do. :-)

Bernard

Crikey. I'm almost on the same ship sailing on the same sea as you!

G-02X
Sigma Clock-50 v1
Denali 6000 v1

Glad to hear that!
