CHORD ELECTRONICS DAVE
Dec 18, 2016 at 2:53 AM Post #6,211 of 25,909
I have an INNUOS Zenith Mk.II with a 2TB SSD and it's sonics are fantastic.

Do you have the Zenith directly connected by USB to the DAVE? See next point.
 
  I've got my eye on this network player and music server since they were able to beat so many far more expensive ones:

The component doing the magic there is the microRendu, which I don't really class as a "server" or "music player", more of a server "end point", which cleans up the signal downstream of the acual server playing the music. The mR  does the cleaning bit so well that it no longer matters (as much) what the actual server is, be it a cheap PC or specialised expensive server. There's a new kid on the block by SOtM that allegedly sounds better and costs less than the mR, but I've yet to try that.
 
Edit: The server/music player does need to handle the End Point concept. Like HQ Player's NAA mode, and Roon has an equivalent mode that I haven't yet tried. Going down this route is a bit more complicated than connecting your server direct to DAVE.
 
Good, but not enough... I also had starting to marking the CD... Until I have discovered that Each single tracks need to be controlled for the correct phase... (unfortunately...) No one only CD with all the tracks in the same phase...

That may be true, but I haven't noticed it - i.e. whenever I randomly tried a few tracks of any CD, the've always been the same absolute polarity to my ears. So if there are differences, they are probably (hopefully) exceptions. It's not something I'm going to explore further, because I'm not that OCD :xf_eek:)

Ripping isn't a factor for me since the cheap drives I already have can easily rip perfect copies of the audio from any CD. (Which can be verified by analyzing the data from countless other drives via the AccurateRip database.)
 
As for storage...gosh...I got a 12 TB hard drive array years ago that worked fine until this year. Now it's a hundred times slower and I can't figure out what the problem is. I'd rather not send it out to a third party. Spent $1,100 on the darn thing and I'm paranoid... If I'm not able to fix it, it would probably take weeks on end to transfer all the data to other drives.

 
If you are interested in the MicroRendu, you might be interested in this  isolated ultracapacitor power supply from Vinny Rossie (ex RedWine Audio).  A very nice PSU upgrade for the MicroRendu ...

Why not consider a music server with integrated CD ripper instead of a CDP?
I have an INNUOS Zenith Mk.II with a 2TB SSD and it's sonics are fantastic.

 
Well, I just purchased +2000 classical CDs from a Friend, and I prefer to listen to them with the pleasure of choosing randomly the CD (old fashion may be :wink:.  I will then may be rip the one I prefer.
 
Also can you tell me why you chosed the INNUOS rather than an Aurender ? Why is the INNUOS superior to Aurender which has a good history and a very polished iPad app ?

Wow, over 2000 CD's is a huge investment in Redbook, so congratulations and happy listening! 
 
I'm familiar with the INNUOS ecosystem and wanted an inbuilt CD ripper for convenience, so chose the Zenith over an Aurender unit. Plus the Zenith is Hi-Fi Plus magazines `2016 Server of the Year'.

“The Vitus is a device that stands as an antidote to some of the latest crop of ultra high defnition digital. So much of that stuff just drift past me, as it’s so often drained of natural colour and with no sense of communication whatsoever. The Vitus sits squarely on the other side of the fence, offering certainly high – but not hyper – definition. I suspect we are caught up in a numbers game here; good audio should be about the quality of the sound, not just the size of the file.”

Yeah, but now he says the SOtM sMS-200 is better than the microRendu and he sold it, so there's that.

  on this topic, has anyone used Microrendu as a source into Dave?

 
Many have. romaz has especially posted a lot of info about it. That server thread I linked to is worth checking out.
 
The component doing the magic there is the microRendu, which I don't really class as a "server" or "music player", more of a server "end point", which cleans up the signal downstream of the acual server playing the music.

Edit: The server/music player does need to handle the End Point concept. Like HQ Player's NAA mode, and Roon has an equivalent mode that I haven't yet tried. Going down this route is a bit more complicated than connecting your server direct to DAVE.

 
In the context of a music server system, the network player and server endpoint you refer to are one and the same. (For example, the music server can run the Roon core, while the network player would be the network endpoint. Some servers have internal network players too.) Click here and here to see more of what I mean.
 
And yes, I was made aware that the mR is the important piece of that puzzle by talking to owners. Some told me that it sounds the same whether you use it with a basic PC or fancy music server. Others insist PC sounds worse. I still want a dedicated Roon server in order to have everything separate from my computers. But I did also hear about how using the mR with a PC and HQPlayer with NAA can sound better than using it with a fancy server. Since I do have HQPlayer, I'll have to try that when the time comes. Perhaps the Roon mode you mentioned would sound equivalently better.
 
Oh, and if anyone wants some interesting info on making the most of the microRendu or other network players:

I researched power supplies for a few hours in the past. Looks like the Sonore Signature Power Supply and Paul Hynes SR7 are two of the best ones for the microRendu. I'll have to look into how this one you linked to compares. (If I already did, I forgot.)

If I hadn't spent tens of thousands on CDs in my lifetime, and on top of that foolishly wasted most of my money (in a former career) on things I didn't need before I had the sense to become an audiophile, I would have already been able to get an ultimate headphone system, including the DAVE.

(Now I have to work my way up all over again, with a new business model I haven't implemented yet.)

Ah, I haven't talked with him in awhile and don't keep up with that thread. (Too bad it doesn't have an updated ranking in the first post like some threads have.) Thanks for the heads-up. (After looking, I realized that he actually posted about it in this thread here.)

  question for Rob Watts
 
I understand that the Chord Asio driver ensures bit perfect output, but what about the Windows Wasapi driver?
 
Thanks

If the app that uses the driver is bit perfect, then both ASIO and WASAPI are bit perfect.
 
With Dave it does not matter which one to use as my tests revealed no difference in SQ; but with Mojo ASIO sounds a bit better; which is a little odd as they were both listened too in bit perfect mode. I suspect that the reason for this is ASIO is a direct path to the USB, but WASAPI is via Windows and I suspect it involves more processor activity, hence more noise. With Dave's galvanic isolation, and with the Windows lap-top on battery, effectively we have perfect isolation from RF noise upsetting Dave, so you can't hear the difference.

Can anyone (probably Rob 
wink_face.gif
) help me with the exact output impedance of the single ended output of DAVE? I'm a bit confused because I can find all kinds of values both on the Chord site and in this forum.
 
I read a value of 0.0055 ohms as a general value on the Chord site. But what's this about? SE,? XLR? HP output?
Then I read values from 0.05 to 33 ohms on this thread.
 
So I'm a bit confused. What is the correct value for the SE output. (and perhaps also the value for XLR?)
 
I'm curious about this because I like to do some matching-calculations. I like to know the ratio between DAVE and my power amps (input impedance 10.000 ohms). Purely out of interest and hobby.........

oh i know them feels, many times in the past i have wasted quite a bit of money just because i had it instead of buying something i really want. live and learn eh.

TNX

Its 55 milli ohms or 0.055 ohms on the SE outputs (phono or headphone). XLR is 33 ohms. For connection to power amps, the OP impedance is not relevant - but lower impedance makes the interconnect dielectric less audible.
