  Heard from others said Mojo‘s wasapi driver sound much better than asio in windows. I tried yesterday with DAVE with Jriver21, can't hear clear difference. Any suggestion for select the driver?
 
And I compare mine CAPS with aurender n10, n10 is different, round and stable, but not better. So I will continue using my windows8.0 system.

Have you considered downloading Windows 10? There are only a few days left of the Microsoft free upgrade offer.

hi all,
 
I am reporting that this really inexpensive USB cable has some of the isolation and clarity characteristics when using the microRendu with DAVE.
 
https://goo.gl/n2ni5Y
 
I do not know why this is, this USB is nothing special in specs except for the two Ferrite chokes on either end.
It's light weight, thin tubes with gold contacts.  But heck, if you can get almost the microRendu sound without extra add-ons, why not.
Been running non stop with this USB cable since yesterday a playlist of DSD64 to DSD256 tracks with no dropouts, pops or pauses.

You don't need to spend a fortune on the USB cables (although there are many suppliers happy to persuade punters otherwise, and buy $500 or $1000 cables) - just make sure that the cable is well shielded, the connections between the cables are securely formed, and the wire properties fall within the specification limits of the USB standard.
 
looks like you have found a cable that ticks all the boxes, and is relatively cheap.

you are right, I have saying the same thing from past few days. use a good usb cable ( not necessarily extremely expensive) with a ferrite choke at both ends . use a laptop in battery mode and add audioquest jitterbug between the cable and in spare usb ports. ( audioquest jitterbug may not have much positive effect but then these are very cheap as compared to micro rendu and at least jitterbug will not degrade the sound. this will be a simple and hassle free setup without any extra emi rfi due to wi fi . what more even an Android in airplane mode using uapp with a very short usb cable having ferrite chokes at both ends (just like a dap with mojo and Hugo is used with a short usb cable ) can be a very cheap and yet extremely clean source for dave.

Maybe.  It's the HFC MC-6 Hemisphere.  With my DAVE and everything else I've plugged into it, the difference has been significant and it will come with a 30-day satisfaction guarantee.  It will come with Furutech's best GTX-D(R) NCF receptacles.  Not sure if the new Furutech Schuko NCF is an option.  If there is interest, PM me and perhaps a group buy can be organized at a significant discount.

Hi Roy. Just placed an order for the MC-6 Hemisphere. It sounds like they don't usually keep it in stock and I've been quoted a 2-3 week wait before receiving mine. I plan to get a CT-1 power cable as well but, since I have to wait at least 2 weeks anyway and the CT-1 is in stock, I figure I can wait another week before laying out the extra money. BTW, what cables do you (or Rick) recommend for  connecting the MC-6 Hemisphere to the wall outlet? As it stands, I have some Black Sand and relatively lower end Shunyata Venom cables lying around that I can use. Thanks.

It's interesting that this cable fixed your dropouts, Paul, but it's hard to argue with something that works, especially something this cheap.  In my testing, as long as you keep the USB cable length relatively short (<2 meters), I was unable to distinguish a difference from one cable to another although dropouts have not been a problem for me for quite some time.

But on to more serious matters, here are my initial impressions of the KE washing machine pads and how they affected DAVE:
      http://www.head-fi.org/t/693686/great-bargain-isolation-discovery/15#post_12695813
 
Edit: To put this into perspective, I'd say the KE pad effect on SQ were more obvious than my impressions of optical cable differences, but both I'd class as incremental - compared to the microRendu that arrived this weekend, which shows great promise of being a step change improvement.

 My 2nd and concluding impressions posted here:
          http://www.head-fi.org/t/693686/great-bargain-isolation-discovery/15#post_12734333
 
In short, the KE/DAVE/HRS sandwich has been unexpectedly successful for me, albeit not in the way originally intended. Although I'd still class the SQ improvement as incremental, it's a pretty big increment, and I couldn't get anywhere near the same improvement when the same tweaks were added to other components. This is the first time in my experience that any vibration control tweak has resulted in more than a marginal difference - and I would never have guessed that it would apply to something as solid feeling as DAVE. 
 
Now, Beolab and probably many others may find this hard to accept, so I suggest that a DAVE owner in the US gives the KE pads a go and reports back with a second opinion. Apparently, you can get a set for $8 from Lowe's, although $20 may be more typical. The HRS Plate is much more expensive, so try to get that on trial basis.
 
I didn't find the HRS plate unduly increased DAVE's outer temperature. In fact overall the temperature subjectively seemed slightly lower - presumably because the increased space between the shelf improved air flow.
Aesthetically, the combination is acceptable, especially as my black DAVE is on a lower shelf and largely disappears in my dark corner of the room - probably won't be quite as acceptable on the top shelf with a spot light.
 
Which leaves me with a question to DAVE's designers: why 8 feet?

Hi Roy,
 
This $5 USB cable https://goo.gl/VXWg6b  did not fix my dropouts issues when used with the microRendu.  (To that end, I am considering ordering more powerful computers in September or when Apple announce the new Macbook Pros.)
 
What I was excited about is the quality of sound from this cheap USB cable when used directly with the DAVE and my 2014 mid Macbook Pro Retina. The sound was very close to what I loved with the microRendu when it did not drop or pause.
I get the holographic vocals which made singers come alive, the isolation of instruments which made them easily identifiable and the slight expansion to the frontal sound stage I enjoys when using the microRendu with DAVE.  
It is certainly not 100% as good as the microRendu, but it's darn close.
 
Of course, I will not stop trying more things.  That's what we enjoy.

  I wonder if clip-on ferrite chokes would yield a similar result.

I found them to help when I placed one on the USB lead from my phone to my Mojo. But they can only help remove RFI, they cannot remove clicks, pops, stuttering that are caused internally within the source - by this i mean caused by the resource problems or caching issues internal to the phone/laptop/media server/NAS etc.

The Devialet range of amplifiers are completely digital inside (even analogue inputs get converted to digital, before any DSP or amplification). Chord also have their Matching amp the Mezzo 75 which is the same dimensions as the Dave which may be stacked on top for a neat high end system.

Alternatively the Chord TToby is released next month, but it is intended to partner the Hugo TT.
