 ~~Yes the off ramp I have has all the options and his power supply too.

Al, can you comment on the new Off Ramp Hynes designed AC power supply ($700 upgrade)?   Have you done any comparison with the standard wall wart?

Did anyone try the old firmware (#3, IIRC) with the Master-7?

 

I much preferred this one to any newer firmwares when I had the NFB-27. The sound was fuller and warmer (or the other were brighter and leaner, pick you poison).

The best sound I had was using the USB-32 input. The Stello U3 and Concero were probably on par technically, but I preferred the integrated solution for convenience (and the warmer sound).

Yes I have it too. I got the unit with all options of dual clocks And all the rest too.
But I did not try it with wall wort at all as compared to the new deprecate 700 giggy psu.

I will try when I can. But I'm sure it improved it as the pp does with the ap1.
I asked Steve why not a battery supply and his answer was. The reg psu is faster
Than a batteries response time.

Hello,

 

There is another product that can fed the i2S interface ?

 

Where I can buy a I2S cable ? A RJ45 from computer can work ?

I saw a Terralink-X USB-I2S converter on eBay. Has anyone tried this cheap USB-i2S transport with the Master 7?

Hi all,

 

I've recently received my master 7 and I just wanted to check I was getting all the settings correct in windows/Foobar.

 

I've installed the latest drivers from the Audio GD website. In the output setting in foobar I have selected KS: Audio GD / 24 bit for output data and 1000ms for buffer length.

 

I'm a little confused as to which option to go for to get the best results - WASPI / KS / or ASIO4ALL. Also wanted to know if setting the output to 24 bit when i'm playing FLAC at 16Bit is a bad idea - will this degrade the sound in any way?

 

Any help would be much appreciated.

Why would you not use the excellent USB32 built-in? Better than any converter I have tried.

Using the built in usb with via asio (note, not ASIO4ALL. The via driver is a little checkbox that you have to check when installing the drivers) is the best i've heard from my ref 10.32, as it makes the soundstage a more holographic vs wasapi or ks. I'm not so sure about the bit depth question but everything sounds more open when jriver resamples the bit depth to at least 24. Probably would be fine to set foobar to 32 bit output.

KS is not great with WIN7 or 8.

You should test yourself whether asio or wasapi is best for you.

If you try wasapi event, the following could prove useful:

I think the USB32 input on the Master 7 is very good, in fact I would rate it as great under integer mode on OSX.

 

Windows drivers don't sound as good as OSX integer drivers to me though.

 

I2S input on the Master 7 is a step above any other inputs though as far as neutrality and detail. This is using A-g Reference 5 digital converter with usb32, TCXO and I2S upgrades.

 

BNC input is better than the RCA digital input on the Master 7 and I plug my A-g CD7FV into the BNC input. Less warm and opaque sounding.

 

The AES/EBU input is about on par with the BNC input but with a slightly different but not necessarily better presentation i.e very large soundstage

 

My comparison of rca, bnc and AES/EBU is using the M2Tech Evo Stack i.e. EVO usb converter, Evo external clock & Evo external battery power supply.

 

I love the Master 7 and will sadly mourn its passing. The only other DAC that really interests me is the Metrum Hex.

Wow you really know that dac . Well said. I one for you. I use an offramp5. All options and his new PSU as well. And his supplied cat7 shielded cable too. It makes that dac really special. . It is a great dac . There is a new ultra hi end crazy price dac called the TRINITY. it uses 8 pcm1704. Chips per side a total of 16 chips. There is just something special about that chip.
The dac is about 60k with the transport .

I use it and I am really happy with it.

 

But there are people stating that some external USB/i2S converters (e.g. the Off-Ramp 5) are better than the embedded USB one. I am very curious to know the true about this. I do not expect that the Terralink-x is better than the embedded USB converter but I don't know anyone with the Terralink>M7 experience.

I have the off ramp. 5. . It is better in mAny ways . But I am not knocking the USB either . The dac is just a great dac . One of my favorites

Yes to say that any external usb converter would be better than the internal usb32 implementation is absolute rubbish.

 

The M2Tech Evo without external clock and battery PSU definitely isnt better. I'm not even convinced that my Audiophilleo 1 is.

 

I believe that the PC usb32 driver is a lot of the problem as usb32 sounds much better on OSX Mavericks integer mode driver.

 

Personally I would love Kingwa to make a higher end version of the Master 7 perhaps 3 box with mono 8 x pcm1704uk per channel and a separate digital input box (perhaps with fento clocks) like the Wadia 9 system as A-g's pcm1704uk swansong.
