CHORD ELECTRONICS DAVE

[JaZZ]

 

 

  Commercial ADC's are not very good or transparent; hence why Davina's ADC.
 
Davina will also allow redbook conversion to M scaled files; I plan to M scale some of my music to play back on planes with Hugo 2. Of course, its pure digital to digital transfer, so in effect I will be listening to M scaled music without carrying around an M scaler. Perhaps we may see music being re-released as 705/768 kHz M scaled...

Would it be possible to make some M scaled material available as WAV files so that DAVE/Hugo owners can make useful comparisons?

It will be technically possible to do - and I would love to do it. But I don't know what the legal situation regarding clips and copyright. I guess I would need permission from the copyright owner.

 
It would also be interesting for the copyright owner if you just make excerpts available – sort of promotion. So I really think it is doable, and I would like to get an idea of the M-Scaler.

Perhaps if you asked someone who makes high quality recordings and has a download store - Hyperion records would be my choice. Then folk could buy the redbook from them, thus satisfying copyright issues, and get the MScaled version either from Chord or again from the same place. I think most of us would be happy to pay. Hyperion make some absolutely outstanding orchestral, choral, and chamber music recordings which they sell as CDs, or redbook downloads or hires downloads for very reasonable prices.

It would be the ultimate comparison! CD vs MScaled CD vs redbook download vs MScaled redbook vs Hires Studio Master vs MScaled Studio master.

Yes, the DAVE's headphone output blows everything else away. Period.
 
 

 
Does it really?  So, just out of curiosity, which is better  -- a TOTL headphone (e.g. HD800/S, Focal Utopia, etc) driven unbalanced direct from the Chord DAVE headphone amp, or DAVE xlr output to Headamp GS-X Mk2 driving the same headphones in balanced configuration?    Or does it matter?

I feel sure Rob that Chord Electronics' friends at Metropolis Mastering would both have the authority and ability to produce such a comparison disc/file in under an hour, if they had a mind to.

The headphones you listed would both be fine with single ended output of DAVE: more than sufficient power to drive them single ended, with fewer components between the analog output and your headphones.   Based on previous posts in this thread, my understanding is that the balanced output has an additional amplification stage, and is capable of driving 10x less current than the single ended output.
 
I haven't directly A/B tested my HD800 with single ended vs balanced output to an amp (I no longer have a headphone amp), but I have heard an improvement driving a 2 channel amp single ended vs balanced.  For the DAVE, since it is (essentially) natively single ended, if you can get away with it, best to stick with that.

Is 400HZ power OK with Dave?

I recently received a power regenerator, which outputs 110V 60HZ regular, as well as 120HZ and 400HZ @ 110V.
The 110V60HZ works surprisingly well, the improvement is huge. I'd like to try 120HZ and 400HZ but wondering if this is OK with Dave? I have tried CD player, which power supply is transformer, works great. But for switching power like Dave is using, I have no idea and dare not to try until if someone tells me this is OK @400HZ...
Thanks a lot.

Given how revealing DAVE really is, it should be well worth the investment to investigate the improvements when a better source component is introduced.

Basically the best clocks out there are DuCULoN and sCLK-EX

And then we've gotta power that with a clean source and the output impedance should be very low, Paul Hynes Design should be one of the best and then we've got some options with ultracapacitor banks

If you're just looking for a plain and simple audiophile OTG cable since that might be good enough for a flagship Android phone, maybe you could talk to PhilW and find out if Vertere Acoustics were able to do something

http://www.head-fi.org/u/145703/philw

This is the flagship USB cable called Pulse-HB with an optional micro USB config, sometimes they could be willing to make something different such as OTG cables

You could read some impressions of Pulse-HB below

Simply ask PhilW about the possibilities of making an OTG version that's looking just like this one here

Robb Watts has said that he has found that different sources make little difference to Dave and with the implication that it is not necessary to spend money on the array of gear mention above with the Dave. Likewise I have noticed that he eschews exotic USB cables etc. This is exactly my experience with Dave. Obviously if it makes you feel better then by all means have a go with an exotic cable but the chances are that a well made $20 cable will do the job just as well with the Dave, if not better. I also suggest that people take a big reality check and closely assess the foo content for a USB cable where a 100 hour burn in is suggested.

Mm...subscrib8ng again bec of forum update.

Mm...subscrib8ng again bec of forum update.

Are you using your phone to get on headfi or using desktop? Either way your subscribed threads are still there. It was just more difficult for me to get to them over mobile.....

 

[jlbrach]

it is a major problem to access things with this new upgrade....i used to be able to easily find offerings i had for sale which now is a major inconvenience as is most everything else...i wish they could give us the option to go back

 

[Deftone]

I hate how it does not show you how many posts have been added to your subbed threads since not looking at them, like it used to.

 

[jlbrach]

also on items you have listed for sale why does it no longer give you the option to bump it etc...also the picture i had in an ad no longer shows up..all in all IMHO an awful upgrade

 

[Imusicman]

Agreed. Using the site for the 1st time since the so called "upgrade"

What an awful user experience

Hi all, a question for any microRendu + LPS-1 owners feeding their Dave. Or SMS-200 + LPS-1

Have any of you tested the mRendu + LPS-1 combination vs a direct PC USB connection?

What were the differences you heard? And yes I know Rob said it shouldn't matter what USB source etc etc, but just a question for those that have the microRendu or SMS-200 + LPS-1 .

Cheers fellas !

I recalled that someone here mentioned that he used the headphone out to feed his Stax amp in order to make use of crossfeed.

I got curious and asked Rob. Apparently, when the crossfeed is set, it is set forever, for all outputs (regardless of whether headphones are plugged out, the DAVE is put on standby, or even turned off). In effect this means that crossfeed is a setting like any other, just that you must plug in headphones to set it.

Plug in headphones -> Set Crossfeed -> Unplug the headphones and enjoy the crossfeed settings through the external amp of your choice.

So now I'm using Crossfeed with my external amp, via the RCA inputs!

My friend with speakers apparently has also been using Crossfeed 1 with his speakers
