I use Isotek Evo3 Sigmas for my electrics. I think it provides very clean power. I am impressed by Isotek tbh. I recommend people borrow an Isotek Evo3 Syncro cord and stick it into their power amplifier straight out of the wall and hear what it does for your dynamics.

I have two Syncro’s. One for my power amp and one into the Sigmas. I was sold on them within 5 seconds

How many of you own the black model? Does it scratch easily and does it show dust, fingerprints?
I own black. Yes it shows dust very well. It hardly shows fingerprints. I reckon it's hard to scratch, but I'm not trying to scratch it. The window is glass so that won't scratch easily either.

I'm completely happy with black and wouldn't contemplate owning a silver version. When I bought my black one I waited 12 weeks a year ago instead of taking delivery of a silver one that was in stock. I listened to a silver one before I ordered, so I know what the two finishes are like.

Dust will get inside, since the holes in the top are for ventilation.

Actually when I say to you guys that I do not own any power conditioning equipment or fancy mains cables I am being slightly economical with the truth.

No, I do not own any of that stuff.

But the power company does.

And they have a lovely big transformer dedicated for me and just two other houses just outside my house.

I know for a fact that my neighbours are away for much of the time so effectively I have the same power supply as that Japanese guy who got his own pole and transformer installed.

And this is it this morning. :grinning:

I will report that Ted Smith of PSAudio has taken a few pages from Rob Watts playbook as he continues to improve his DAC implementation: less noise, more SNR, better timing. The just-announced Directstream firmware update (RedCloud) appears to be more than incremental. The previous Directstream version's (Huron) sound quality was basically a tie with Hugo2 ...in a review I did for the head-fi H2 tour.
If any DAVE owners can perform an A/B with the lastest Directstream, I'm sure the results could be interesting.

What I found amusing from the Headfonia interview is that Rob Watts went with the DSD/PWM/PS audio approach with the DPA PDM 1024 DAC back in 1994 (not to mention the initial 1989 DSD256 implementation) and then decided to go with Pulse Array DACs instead. It’s nice Ted Smith is trying something 23 years later. That said, Emm Labs also stuck with the DSD/PWM approach.

Hi Christer,Deftone Dont Be A Genre or only Audiophile grade sound quality kind of Snobby Remark. It is sad there are so much good music not so good quality and if you dont like low band like Queen than keep yourself. Some might like them old bum like me listen Heavy Metal and Old classic rock on over 200K worth system but also love classical,jazz and blues. Its not fun to read like Genre or Music Snobby Attitude.

I think you missed from my comment I was not being serious. I am one of the people where music comes first then if it happens to excellent quality it’s a bonus.

I will not listen to music I don’t like just because it’s well recorded. I have been in to rock and metal since a teenager and still listen to only rock and metal now, most highly compressed and still wouldn’t choose better sounding jazz or classical over it as it’s what I love. Megadeth, Slayer, Metallica etc

Hi Deftone! That was What I am thinking, you correct my misunderstood so thank you and Respect, Rock and Roll Rule !

Curious about the creator of the Chord Electronics Dave, Hugo and Mojo? Our Rob Watts interview is now online for your reading pleasure.
An interesting read, perfect for when you're bored of X-mas shopping :)

Thank you for the interview write-up. I guess the headphones mentioned are MrSpeakers Aeon closed back version right? How do they sound when paired with Dave?

My closed Aeon's are surprisingly nice with the DAVE. The only cans I have that scale better with the DAVE (Mojo to Hugo2 to DAVE) are my Sennheisder HD800's, but the Aeons are very close. I haven't heard other TOTL cans with the DAVE though so I can't compare (HEKs, Utopias, etc).

Aeon's are the best closed cans I've heard, and perfect for the office. I recommend giving them a listen.

Quick summary of my question: Can I just plug DAVE into the wall with the stock power cord and be OK?

How do DAVE owners handle power to their DAVE? Do they use power conditioners or high-end power cables?
Does anyone use the stock cable?
Does anyone just plug it right into the wall?
Is it OK to take this minimalist approach (stock cable directly into the wall)?
Does anyone use so-called "audiophile" power strips ? (I have not tried them.)
Thanks.

(Over the years with other digital components and amps, I've had mixed results with various power conditioners/power cables/regenerators, many of them harming the sound, notably making the bass opaque. And with regenerators, I heard sizzling highs. Some silver-based power cables also over-emphasized the highs. I've had some good results with Shunyata cords, but I have no room for these firehose-like power snakes or their Hydra boxes in my desktop setup.)

In this 21st century of our calendar, if you are in a situation where you have an essentially private electricity supply because you have no electrically noisy neighbours or you’ve paid a power company lots of money to have a private and relatively noiseless electricity supply, you are in a very rare and/or extremely privileged situation. Enjoy it!

In my situation I am in a city where every house has more than one air-conditioner and usually has at least one air-conditioner running during the day and maybe one in the bedroom for sleeping at night. So the electrical supply is extremely noisy and here, voltages have ranged from 208 to 257 volts in a nominal 230v supply. However, the voltage is usually in the low 240’s.

So the above range of voltage, let alone noisy circuits, makes hi-fi audio pretty variable in listening terms. So I needed to do something. For my current speakerless DAVE headphone system I use a double on-line UPS that almost disconnects me from the noisy mains and delivers a constant 240v supply. To filter out the remaining noise from both the outside world and my own noisy circuits with air-conditioners refrigerators etc, I have installed a Shunyata Research Denali system with their Sigma and Alpha range power cables.

The sound quality was OK with the double-online UPS but adding the Shunyata Denali system took the sound quality to a night-and-day variance for me. So much so that my audition of a BluDave combo just didn’t do anything for me in my reference CD set I took with me. Mind you, it was an audibly noisy show floor so I might have been missing out.

So to answer your question about using DAVE directly plugged into the wall, Yes you can and depending on your existing gear, you may find it a step up in audio quality that is anywhere from nicely different to awesomely good (if awesomely is not a new word).

But for me, the laboratory grade power and electrical supply “cleaning” and management devices I installed is a no brainer and provides musical enjoyment far exceeding the standard wall outlet only approach.

It all depends on your current situation as to whether spending on electrical supply management and “cleaning” equipment is worth your hard-earned cash splash.

I hope this gives another perspective with respect to the normal population’s electrical issues for hi-fi listening pleasure.

FYI if the source is of inferior SQ ,it stays inferior no matter how much money ill-informed audiophiles spend on cables, power or any snake oil treatments that can not in any way improve matters. " crap in crap out".
If synthetic multi-micked electronica studio stuff is the kind of music one mainly or in really serious cases, only listens to, there is NO reason whatsoever to spend more than a few hundred dollars or € or Pounds on a complete Audio system IMO.
If your source material already has severe distortions included in the recording as most electronica has, any 1970s amp or early rbcd player is good enough.
For those with space enough who want "bang for the buck" there are really cheap big PA system speakers that will deliver all the big boomy distorted bass you would ever need.
Almost every time I get to audition sometimes extremely expensive system in audiophile shops without bringing my own music that I love, I walk away with the feeling Oh my... what an incredible waste of money if one only plays crap music that would sound basically the same on any boombox system at Walmart.

So this is a new video:



I won't spoil the video by describing it here. But I will say that I think Hans is on the right path here, he has realised that devices such as those sold by SoTM are not the final solution.

The most important thing about this video, the factor that gives it credibility to me, is how he uses sibilance as a "comparison tool". He talks about improvements that come from various changes to his system, but he finds many of these changes make no meaningful difference to sibilance.

In my opinion, a key indicator that you are solving problems in system setup is how it handles "difficult" sibilance. In my experience RF causes a lot of sibilance problems and I've had absolutely fantastic success on that front. So when he finds a way to improve his system which appears to be due to RF filtering, it provides an independent opinion which I hope helps other people to get their DAVE working the best it can.

Now, someone needs to persuade him to try lots of ferrites on the final USB cable...

Dude, the goal is to reproduce what was made as best as possible. Whatever that is. Doesn’t matter if it was recorded in a way you don’t like. If people like it, there is more enjoyment from better reproduction. Period. Ray-dude posted his experience of listening to Nusrat Fateh Ali Kahn after getting his Blu MkII and being blown away. I listened to some. Not my cup of tea, but I totally appreciate his pleasure from it.

I believe that every performance has artistic merit (art being defined as the capture and conveyance of some sort of emotional truth or idea). The performer is working to convey something, the audience is working to receive it, and the engineer is working to capture it.

If a reproduction chain is able to reproduce that, even if poorly captured, it is akin to a time machine and transporter rolled into one. It is very rare that I don't enjoy listening to some new piece of music and finding that artistic intent. It may not be for me (so I may not go back to it if I don't care for it), but I appreciate and celebrate what is there, and that it has meaning for other people. I learn as much about myself from things I find resonances with as from things where I don't (and often more from what I don't care for). I also learn more about what matters to other people who resonate more with that sort of thing.

In the case of Nusrat Fateh Ali Khan, listening to that performance with the Blu2 was the first time I was able to completely feel like I was in the room with those musicians and that audience (vs getting afterimages and hints) and got completely swept away. Incredible experience (and thank you for giving it a listen @jarnopp...not my usual cup of tea either...see the back story here: http://thingssoimpossible.blogspot.com/2012/12/2012-albums-of-year.html along with the absolutely incredible Jeff Buckley/Nusrat coda: )
