Audio-Gd Master 7 - Discrete Fully Balanced DAC (PCM1704) - Page 208

post #3106 of 3290

Mine's Jan 2014 and I had no problem fitting it.

 

If you do have to enlarge the opening, you could probably do it with a decent set of files and some patience.

You have to enlarge the opening if replacing USB32 with the HDMI I2S module.  This is for customers wanting both RJ45 and HDMI I2S inputs.

Is it a relatively simple affair to convert the HDMI input to RJ45 and vice versa?

 

I can solder if necessary.

 

I have HDMI on my Master-11 but might pick up a transport that only has RJ45 out for I2S.

I remember it being pretty easy on my M7.  No soldering involved.

 

As usual, the instructions on the website are a little confusing.

Master-7 ON IT'S WAY!

Joining the Master-11 I've had for a month or two. Master-11 was purchased as a DAC/Headphone amp to replace the OPPO HA-1 which for my ears was a bit 'harsh' and too 'detailed'. In other words, just the opposite of the Audio-GD sound signature.

But the Master-11 kept sneaking up the stairs to the loft where the main system resides, leaving me with a DAC/Headphone Amp for my laptop.

So, the just-ordered-a-few-days-ago Master-7 is already in LA so it will be here soon.

Would love to hear your thoughts on the M7 vs. M11 DACs after you get some listening time in!

Will do, easy to leave the Master 11 in the main system with the Master 7 after some break-in (a few days on in a cold house should be safe).

That said, I almost went with the DAC 19 Anniversary Edition as it should be every bit as good as the Master 11 and I don't have a balanced preamp anyway so...

But 8 PCM1704 U-K should be better than 4, right?

We will see soon.

Couple days at most it it's already in LA and I'm in SF.

No.  I2S protocols are all over the map.  RJ45 usually means LVTTL I2S (SE).  HDMI generally means LVDS for balanced I/O signal.

 

They are not interchangeable.  Perhaps the different connections to the M7 are simple, but the signals themselves as well as the pin-outs are different.  That's a problem with I2S.  There is no standards in place for consumer audio.

He is referring to changing the Master 11 from a HDMI input board to an RJ45 input board.

As I said, on the Master 7, it is just a case of switching the boards and making alternate connections. I would assume the Master 11 is similar.

Hi, the question may have been answered somewhere but I'm a little confused about the real max sample rate that can be accepted as input by the Master 7 through USB and through I2S

On the website you find these two (to me) contradictory statements:

Supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit ability . 
Resolutions support 16 / 24 / 32 Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz ( USB / I2S)

 

So my question is: admitting there is  a difference between ability and support, can I concretely send a 384k signal to the M7 or not, when using the USB and when using one of the two I2S ports?

 

A somehow related question: can all the upsampling and digital filters be removed when using with either USB or I2S inputs so as to operate it as a truly NOS nonfiltered dac?

post #3118 of 3290

I operate my Master 7 as a fully operating NOS dac.

You can send 32/384 to it but it will only decode up to 24/192

I believe the 32 bit will lose the bottom 8 bitsand the 384 will be down sampled to

192 if you use I2S.

Good to know. Fully NOS and also fully unfiltered (meaning with digital filtering being done in pc)?

What do you mean by you can send 384 but it will decode onlh 192? Is there a downsampling procedure somewhere in it?

That would be a bit awkward, it seems.

My plan is to use it with a player like HQplayer who works best when upsampling and implementing digital filters and then sending the signal to a dac that takes the highest possible sample rate and adds not filters whatsoever.

For testing, i would like to put off the first jumper 'bypass' but it's glued to the pins. A tips to remove it safely ?
