Audio-Gd Master 7 - Discrete Fully Balanced DAC (PCM1704) - Page 71

The resisters are located under the board the the ribbon cable terminates on . Remove the board and change resistors or put a 140 ohm reisiters in parrallel to get the needed 75 ohm you are looking for . Keep in mind that the off ramp is 75 ohms and Steve says this is important but dac ladder is getting wired results . Have you guys just tried the off ramp with his cable . This is what I have and it did improve the overall clarity enough to notice right away , but it did not change the over all tone very much. Just some thoughts.

hm is kingwa aware of these osciliscope readings and issues with off ramp? i wonder if he could offer some of these resister mods as an option on new units

Why would he care about unsung a product with his that he has no association with. When I contacted him about the imp value he told me it was 140 ohms if I remember right and dac ladder says it's 220 ohms . So I really cannot answer as to what mine is as it works fine with the off ramp and Steve's cable as is . As I understand what dac ladder is doing , but he appears not to be happy with his results . And honestly I just want to play my music anyway.

Once you get an oscilloscope, there is no turning back :tongue:

I had two of them . I sold them. One was portable for the field. And the other was fixed bench. I just do not have a use for them anymore. As for this hobby. If I can't hear it I don't care about it. And when I am doing room calibrations it's a laptop , DVD ,s and calibrated mic on a stand. And last I am more of a buy it rather then build it type of guy. I know you love to build , I just want to listen. And I spend a lot of time reading here and other sites to learn from people like you and others . There is much to be learned in this hobby. Do you consider yourself an audiophile ? You are, I don't I'm just a guy with a lot toys lol .
And you may call me AL sir...

Likewise I just want to enjoy the music.  My day job is in electronics and don't particularly like doing it 24/7.  But it has been a productive morning while listening to music!

I am very curious about a currently non-existent R2R DAC the ARDA 1401.   Someone should apprise the community on it's current status.

Their ADC is used in some serious expensive recording gear.  More info here:

Hey AL,

 

I do love to tinker with my toys :tongue: It brings alot of enjoyment and satisfaction for me in this hobby than just listening, but I do like to do that too and will often take hiatuses from tweaking lol. Can't say I blame you, enjoyment is the #1 priority here, and if tweaking doesn't do it for you, then so be it! I think the vast majority of us visiting sites like are audiophiles IMO. I don't really know when or why it became a derogative term other than from some of the science templar crowd to try and distinguish/elevate themselves from "everybody else". Taken from Wikipedia, "An audiophile is a person enthusiastic about high-fidelity sound reproduction. Audiophile values may be applied at all stages of music reproduction: the initial audio recording, the production process, and the playback, which is usually in a home setting." According to that, it is those very people using it as a derogatory term that are actually a true representative of an audiophile in a higher form. I wonder why it took such a left turn? ;)

 

Happy Holidays everyone, and apologies for the short OT.

Looking good DACLadder! When is it due to arrive? I have been very interested in this DAC and the progress you're making :)

Looks promising

I presume this is to eliminate the use of cat data wire and use the hdmi
Although hdmi wires Are standard. The ones used in audio applications are of a much higher
Rating. And really expensive too. Like the one I use with ps audio DAC is 500 bucks
The other question I have is about the protocAl. Is it the same using the offramp hdmi
Into the M7. Using the New hdmi change over board.

Yay, scrapped together some money for a Master 7! So poor now!

post #1063 of 3612
You won't regret being being poor for a little while.

Hello, first post here, be gentle :-)

Im considering an upgrade from my audiolab 8200 CDQ (ESS sabre) to new source for my new ATC scm50 actives. Amyone here had the chance to listen to both reference 10.32 and master 7 and would like to tell us how they compare to each other sound wise?

 

I have an offer on a second hand ref 10.32 but are also considering the master 7, but that is much more expensive since I have to buy a brand new one.

Im pretty happy with the Audiolab CDQ and use it both for CD, DAC and preamp, but I have heard that I should try out a well implemented PCM1704-dac since it should be a better match for my speakers. If I go for a ref 10.32 Ill, keep the CDQ as transport and dac variety. If I go for a master 7 Ill still keep the CDQ for cdp and preamp.

 

I have had several cdps and dacs over the last few years: Naim CD5X (Liked it a lot), DacMagic (good, but not that detailed and bit "bloomy"?), Lavry DA11 (good, with a lot of features but a little too polite for my taste and not that user friendly), Audiolab 8200 CDQ (lively and dynamic, and punchy, lots of filters and and interfaces, the best so far), Accuphase DA20 (card for slot in Accuphase integrated - similar in sound to the aduiolab but a bit dry).

I listen to a lot of different music and generes but like a lively and dynamic sound, great sound stage and 3d image.

 

Anyone like to comment and give their recommendations?
