this thread is evolving from the compass thread to the "what is my audio-gd upgrade path after the compass?" thread, heh.

and mbd, i think you'd make a great henchman/bodyguard. "don't talk crap about xyz!" *dishes out pounding*

Hehe we can't help it

Kingwa is making a lot of good products very quickly

You need to stop mixing my words. I never said the compass did any upsampling to 16/24. I stated that it's an oversampling dac. There's a difference between. Upsampling and over sampling. I did see in one post I said made a mistake and said upsampling, if you check all the rest, I said oversampling. Do you homework. Over sampling does not taka a 16/44.1 signal and up samples it to 24/96. Nor did I say it did. I also didn't say anything about wanting a valab. I wasn't even the one who brought it up. All of my post has been toward how I can' wait to get a compass. So get your facts straight. Oh I know your can't help yourself. This has happened numerous times. You just love being wrong. So I'm not going to go back and forth with you. You already have a reputation. So everyone already knows.

You gotta stop, stop it now, if you are too incompetent to setup Winamp, Foobar, Media Monkey correctly, not our problem, nor is it Audio-gd's. Don't like the DAC, buy the Valab, no one cares. I trust the ears of Peete, Curra over some marketing bullcrud by Valab. And for gevorg, stop being lazy. Peete and Currawong themselves have done extensive testing of just the amp.

Just add him to your ignore list. Hes the first, and only, person I have put on mine. I love technology =D

Once I get the Compass in the mail, the first step for me will be to configure my media players appropriately.

 

[csroc]

I've played with a bunch of the different media players and audio configurations, wound up going back to a simpler setup that just worked.

And mbd, well he seems to have a lot of people on his ignore list... I can't imagine why.

 

[punk_guy182]

A'ight guys!

I think that we should all get laid to get rid of the overbuilding tension around the Compass but not all together.

No where. The Sigma Delta process is for digital filtering....it is not upsampled in the traditional sense, what goes in is what comes out. It's funny I spent some time yesterday looking at both data sheets for the CS8416 and the AD1852 for the Zero, had a look in here and noticed the talk was centered around 1852 and what it does.

Here's a link that should help everyone understand what is happening with the Sigma Delta chips...well for the most part ...

Analog Devices: It may be Greek to you, but sigma delta converters are not really hard to understand. :: Analog to Digital Converters

The DSP chip is as important (if not more) to the circuit as is the type of DAC chosen followed very closely by quality of power supply (supplies). If the PSU is compromised the DSP/DAC chips won't matter all that much...it'll sound like ass until you give them a top notch power supply. That should give you pause for thought and explain why the power supplies in all of Kingwa's DAC's (and other gear) are so carefully constructed and (seemingly) massively overbuilt.

Every new DA11 box comes with a pair of XLR to RCA adapters.
They are high quality, and cause no degradation (as clearly stated in the product manual under specifications).

While it is "fairly simple to make a "pigtail" to adapt the XLR inputs to RCA", we supply the unit with the adapters to make the DA11 ready for RCA connector use right out of the box.

Be prepared for a lot of insomnia cure type nomenclature......just check the link I posted (for the simple explanation of Sigma Delta) for a small sample of such...

Your right though, educated person = informed person

Congrats to Curra on the status upgrade (although to me he was already a Supremus before the tittle change).

Thanks Dan for your input.

Well this is good news for those who want CAST in their C2Cs, Im sure a similar XLR to RCA adapter can be sourced somewhere else like here

Thanks Dan. I have followed your products for many years and do not doubt that a DA11 ( or maybe a used DA10 being sold cheaply!) is in my future also.
You have made some great stuff and contributed greatly to A/D and D/A product design over the years. Thanks!!

It's ok, I'm used to reading technical stuff, just in a different field. And at least that book is just the digest version of his "The Art of Digital Audio".

I'll check out that link too. Thanks!

It occurs to me that this question doesn't really belong in the Compass thread.....I'm not nitpicking I'm just trying to keep the thread on topic ...

I'm fairly certain the C2C does not differentiate the type of input signal for a "CAST" like function. I think you guys have mixed things up a little. Full CAST requires the dedicated circuitry if I'm not mistaken.

Here is the C2C page's explanation.....you guys need to read this stuff before posting questions that are answered on the C2C page itself.....


"Design Features:

The technology employed in C-2C Headphone amplifier is at par with KRELL. Previously, this technology was used only in very high-end gears of famous manufacturers. BPM-7110 module is composed of all discrete transistors; it adopts a current working style which guarantees ultra low distortion. This special technique and circuit counteract the non-linearity caused by transistor. The output signal depends entirely on the resistors in the module. The resistors used in our BPM7110 module are the expensive and accurate Israel VISHEY resistors imported from USA. This module sells for over 60,000 yen in Japan. When BPM-7110 with current technology is adopted to make headphone amplifier, the voltage gain and the volume can be synchronously adjusted. Therefore, a high SNR and a low distortion are achieved. Even with a slightly higher gain, there is no overload distortion in effective output range.
This circuit has exceptionally high sound restoration ability.



You can input XLR balanced signal or RCA unbalanced signal. No matter what kind of signal is input, it has the ability to transfer it to current signal and amplify it.



The output stage is also elaborately designed. By applying cascode circuit which is combined by bi-polar transistor and FET transistor, this board not only achieves a better linearity, but also improves the driving force to a higher level than that with pure field effect transistor. Therefore, the sound delivery is more lively and enchanting.

To achieve a better effect, C-2C also employs the complex parallel stabilized voltage supply to get a purer power supply, so that better sound quality is guaranteed.

C-2C uses all aluminum chassis (Black). Dimensions: width 250mm, height 75mm and depth 290mm. Panel thicknesses 8mm.

The balanced XLR input sockets of C-2 are both expensive Neutrik products. Other sockets include RCA socket of CMC, etc. It is soldered with WBT silver solder."

Let me know the details (links, publisher etc) of this book Dro...I'm interested in it as well. For some reason I have a DAC and Tube amp fetish (to go along with the Planar/Ribbon fetish...

)

Yes, you can buy such adapters from a few manufacturers, but they are not all the same quality. Of course one issue is the mechanical construction, but less obvious is the electrical characteristics. One would think that all of those "simple devices" should be fine, but it is not so! When you order such an adapter, most often the seller does not tell you the manufacturer, and they may substitute a different brand at different times.

One of those adapter brands introduced clear distortions (measured on an Audio Precision test system). I opened it, and the connection was not even a soldered wire, it was based on some really poor "friction" and one of the conductors was the case itself... I was really surprised.
