ACSS to XLR connect - possible/working?

post #1 of 9
Thread Starter 
Hi guys,
I own a DAC-19DSP with RCA and ACSS outs. To the best of my admittedly limited knowledge, ACSS is similar to XLR only better. I'm looking at new headphone amp and was wanting an upgrade from RCA. Of course I'll have to recable my headphones (senns so not a major job) but more importantly is it possible to use my DAC19's ACSS out to an XLR in of an amp? What are my options given that audioGD is not making discrete headphone amps any more?

Hi guys, any advice you can offer me?

You'll need to perform a current - voltage conversion in order to connect to your amp's XLR input which would probably negate the benefit of this transmission scheme (if any).

Thanks yage! So there is no way for me to go balanced with this DAC :(

I'm guessing no way I can get an amp with ACSS inputs to use with this DAC? AFAIK the C2C is EOL. Does anyone else follow a similar topography?

I think you're stuck with audio-gd headphone amp / preamp gear as far as headphone amps are concerned. I've only dug up posts related to loudspeaker amps with respect to audio transmission using current (see http://www.diyaudio.com/forums/solid-state/161371-krell-current-audio-signal-transmission-c-s-t-current-mode-technology-cmt.html). There's also the DIY route (or pay somebody to do it for you).

your dac isn't balanced.

 

acss doesn't mean balanced it means current instead of voltage.

 

to use acss you need an audio-gd amp.

Yage, eugenius thank you for the replies, and the help.

 

So it seems I have 2 options:

 

1) Stick with the DAC19DSP and try an AudioGD amp, like the NFB-6 (which has XLR as well as single ended outs)

 

2) Or if I want to try balanced at some point, get rid of the DAC19 and look at something else.

 

Option 1 is obviously a shorter team way out, especially since the DAC isn't balanced. Secondly, unbalanced, the NFB-6 aren't reputed to sound very good.

 

Option 2 is the costlier way out and involves getting a new amp + DAC. Whew!

 

Have I articulated correctly? Please let me know.

I think audio-gd's claim is that ACSS sounds superior to both XLR and RCA so getting an NFB-6 is probably your best option for maximum performance from your setup.

Hi Yage, I am doing exactly that. I also have an Audio GD reference 5 (bought 2nd hand), which I could also use with this setup, and use my DAC19DSP with my speakers.

 

Thank you for your help :) I will also post a review when I get the amp.

 

By the way, in my discussion with Kingwa (who is quite helpful) he mentioned, I would enjoy true balanced out of the NFB-6, which can convert the DAC19DSP ACSS out to balanced, without the need of any additional circuits. It would appear if he is correct, I can enjoy true balanced on this setup. I also bought a 2nd hand (but well kept) Audio GD Ref. 5 DAC, for around 700$, so I do have a true balanced solution at hand too.
