Audio-GD NFB-12 - Page 3

Madwolf:

I sent email to Mr. Ho and asked him both NFB-12 and 11. I agreed that NFB-12 is similar to NFB-11 which should have ACSS. The Chinese web page of NFB-12 did not mentioned ACSS and I asked Mr. HO about the availability of ACSS on NFB-12 and he replied NO. Let me check with him again.

How did you manage to get him, by phone or email

 

On the Website it is written all over the pages on NFB12 page

http://www.audio-gd.com/Pro/Headphoneamp/NFB12/NFB12EN.htm

That it is using ACSS, The Amplifier section of the NFB11 looks exactly like the NFB12

 

Maybe it is due to copyright issue with the CAST technology 

On the Mandrain (chinese ) version of the website ACSS is refered to as CAST技术

ACSS and CAST are the same thing, just different names. CAST is trademarked by Krell, and audio-gd used to call it just "Krell's CAST" until people started complaining about trademark infringement, then audio-gd made the name ACSS.

Well the chines NFB-11 page also do not mention anything about ACSS, but has CAST as the NFB-12

http://www.audio-gd.com/Pro/Headphoneamp/NFB11/NFB11CH.htm

Is there some way to connect my headphone amp and my powered desktop speakers to the NFB-12 at the same time?

Who would I email at audio-gd with technical questions ?  Mr. Ho ? First I've heard that name.

I'm beginning to wonder about the ACSS advertising , because I just noticed a high/low gain switch on the front faceplate of the NFB12 and the NFB11 . 

According to their English product literature ACSS doesn't have gain switches, gain was auto adjusted for different headphones when turning the volume control.  I have headphones that are 32ohm, 64ohm, and 300ohm, I may get 600ohm headphones someday.

So , those are questions I should ask audio-gd.

Your right , I didn't remember reading this quote from their page,

The output buffers are Non-feedback. For low impedance, we applied a diamond output stage which is quite less colored than most conventional circuits.
