Audio-gd Master-5/6/8/9 balanced head amp/ preamp - Page 45

post #661 of 866
I did make a/b comparisons between ACSS and XLR connections maybe a year ago, and found that the ACSS connection had higher resolution, microdynamics, speed. Comparison was with a $600 XLR "Reference" cable, which I know makes a slightly warmer sound without loosing details, and sound via XLR was indeed slightly warmer than via ACSS. After that, ACSS has been the connection to the Master 6, unless I need the have two simultaneous outputs from my Ref 7.1 when comparing two amps.

I just ordered a Master 9- and I would like to understand better what ACSS is.

 

I see the amplifier has RCA, XLR, and 4 pin XLR out.  What is ACSS?   I see no other output?

 

Do I need to re-cable my headphone to use ACSS?

 

Please explain in simple terms.

Never mind.   I just checked Audiogd website.   If I understand correctly from there, ACSS is an improved balanced operation.

ACSS is a conector that inter-conects different Audio-GD equipment for example:

 

  DAC                PRE-AMP            Power-AMP
Master7 - ACSS- Master9 -ACSS-   Master 3.

 

 

If you have an Audio-GD DAC I'd recommend you to ask for the ACSS cables If I'm not wrong it's less than 30$ for the pair.

No-  I don't own a Audiogd DAC.

 

From what I understand from the technical detail sheet on the Master 9 it seems that even XLR or RCA input can output ACSS which is as good as ACSS coming from the source.

 

 "Master 9 is a true balanced design applying the newest ACSS design which can improve the XLR connection to sound as good as the ACSS connection." 

 

 

"Using RCA input, Master 9 can convert to balanced ACSS signal and output real balance signal from XLR and ACSS."

 

Maybe I am misunderstanding what it says.

I think he was talking about the XLR output connection, he made some changes from Master 8 to Master 9 where he improved the XLR and headphone out to be better while  ACSS would retain it's current performance.

ACSS is a balance interconnection natively called by audiogd, and it is used to connect their equipment together that has this interconnection, like you would with others that has RCA or XLR. This is actually is the same technology as krell CAST interconnection, so krell equipment is compatible.

 

The 4 pins XLR input and output you see on the master series of amps and pre-amps are the acss connectors.

Kingwa still uses a mixture of 3 pins mini XLR, and 4 pins XLR currently. AGD equipment before late 2010 are using LEMO connectors for acss, and it was replaced with mini-XLR after which. When the master series starts to appear, 4 pins XLR was implemented from then. So be sure to know the complicated naming convention of the acss cables you wanted, if you make an order from them.

And you do not terminate your headphones to plug into the acss interconnections.

So- what would I call the 4 pin balanced headphone output on the Audiogd Master 9?  Is there a name for it?

post #669 of 866
You already said it, it is a balanced headphone output, and it is the 4pins female xlr connector located on the front panel.

But that 4-pin connector is not called ACSS?

post #671 of 866

The acss conector are the gold ones next to the switches.

 

The 4-pin xlr and 3 pin are called XLR, the outputs on the left and right corner.  There should be another set of ACSS connectors that should be pre-amp outputs.

why dont you post a pic of the front and the back . put something in the photo a reference on one side. then there can be no dobt .
post #673 of 866

 got it.   Thanks to everyone for the lesson..

post #674 of 866

COOL .

post #675 of 866
IIRC using ACSS results in lower distortion, cables can be made by professional cable makers or DIY as alternatives to the stock cables. Switchcraft, Rean and now Furutech all make mini xlr 3 pin female connectors which work well.
