Let's share the headphone amp of Audio-gd (not other product). Any modification, which cable, interconnect, digital / USB cable, power cable used? Result in any characters?

Of course, what source and which headphpone.

Let me start, mine is NFB-10 and DT 880 (modification to balanced headphone).

The system is still run in. Report later.

Oyaide F510 is a 5N silver coaxial cable, I bought the bare cable to diy myself. In the market, there are many OEM cable maker, and many are silver plated OFC, but Oyaide is having
Furukawa to make the cable for them.

In Japan, there are only few bare copper cable maker : Hitachi, Furukawa and sumitomo. And many are buying the OFC cable from them. So it is better to know it and buy their products directly.

I made 2 pcs F510 at less than $1000 with cable and plugs.

Can Hing,

The silver wire offers quick dynamics and tight bass with very good analytical character.

I got a FUN and a K701 headphone.

I also own other Audio-Gd gears, like Ref 3 -> Ref 1 -> C39 -> C10.

I wired the C39 preamp to a headphone output jack, so I can sometimes use the C39 as a headphone amp.

I plan to DIY a cable for linking Sony XA7ES CDP to NFB-10.

Want to buy Oyeida 510 or 910? Any comment on the character?

where I can find the stock cable? cheaper, of course

Finally have time to settle down and do a A/B test of DT880 with balanced plug and 6.3mm plug which are linking to NFB-10.

Very surprise, the result is that the same headphone perform very different when using different plugs.

When using balanced plug, the soundstage is more clear, more energy and density in all levels, more open .....

My feeling is that I will not go back to 6.3mm plug again. I need more time to find out why there so much difference. Caused by the amp? nature of balanced and unbalance?

Any C hing also has similar experience?

With same equipment setup, the balance output always has more dynamic, open and lower noise floor.

This also happened on my connection from Benchmark DAC1 to Adam active speakers.

Hello ching,
I am interested in Audio-gd headphone amp, FUN, NFB-10 or NFB-12 but don't know the character of those headphone amp.
Could any ching can tell me about that?
Since I had 1 pair Adam A7 would connect to headphone amp too, balance analog out from NFB-10 will much better than FUN or NFB-12 RCA analog out?

If you have a Adam A7, it is better to use a balance DAC.

If budget permits, always go for the higher model of Audio-GD. They are worth the money.

Hi Octa ching,
Excuse me, why you brought NFB-3 + C2.1 instead 1 set of NFB-10?
Is there any special feature can be given from your combo?

Currently I have no balance headphone on hand, also there is no analog input in NFB-10, you can only use internal DAC. So I choose DAC + headamp, I can upgrade DAC part or headamp part individually in future, no need to change whole system
