Audio-gd Master-5/6/8/9 balanced head amp/ preamp - Page 38

post #556 of 868
Does anybody knows the output power for 50 ohms single ended?
What's written in the website is only for balanced output.
post #557 of 868

Normally half the balanced output as you are basically using half the amp.

What's the difference? Is it just the back layout and the volume control is better now?

 

Front Layout and remote look exactly the same.  On the back they added a volume bypass button and a hard button to retain volume memory (feature is available in the menu of the Master 8)

 

Looks like there's a single power profile for the 9, where the Master 8 has a switch to go from "low" to "high" power profile.  The output on the 9 is higher than the "high" profile on the 8:

 

Master 8:

50 ohm:   7000MW
100 ohm: 3500MW
300 ohm: 1200MW
600 ohm:   600MW

 

 

Master 9:

40 ohm:   9000MW
100 ohm: 3800MW
300 ohm: 1250MW
600 ohm:   630MW

 

Uhhhh, that's a lot of power.  I cant even get off the "Low" setting with the master 8.

Good Summary. The power is just slight more than the 8 I guess... but I love it. Man... 9W of Class A into my HE-500 would be delcious. My current amp does 10.5W, but it's class A/B and built from much lower quality components.

 

I think the Master 9 will be my end game. I'll buy the HE-6 and either an LCD-3 or the new LCD-X and be done. I'm thinking either Anedio D2 or the Yulong DA8 for the source upgrade...

 

Man that's a lot of money I'm spending... :(

9W in 40 Ohm is the same as the Master 6, which I think basically is a Master 8 in high power mode. However, the M9 does have more power in 100 Ohm.

Hmm, thanks but I don't think so, it could be less than half somehow. Hope Kingwa post the se power output on his website.

I asked Kinwga the differences between the M8 & M9 and here it is:

 

"The Master 9 is improve the headphone output.

The output power is slight increase, but pure class A output is the point.

In sound , the Master 9 have slight better than the Master 8 in headphone output, XLR/ RCA preamp output , and same level on the ACSS output.

The sound is slight richer than the Master 8 in mid and low frequency.

Kingwa"

 

Yummy! I want it.

When I tried out my Master 5 with my Yulong D18, it was a match made in heaven. When I bought my DA8, it was a clear jump up in performance from the D18. I have recommended to several people the DA8 & M8 (now M9) as an end game pairing - serious synergy. Its exactly what I would have kept if If I didn't have the D8 & A8 coming from yulong.

I still might get the M9 as a second amp for the D8 - if I can swing it.

Cool Man! Thanks for the confirmation. I think M9 + DA8 will be my personal end game. I'll probably get the HE-6/LCD-3 and then just be done for a while.

Why?

 

It has been stated before that power is approximately halved when a balanced Audio-gd amp is used with unbalanced phones.

 

So unless something has changed.....

The specs of NFB-10.33 at the AGD site indicate that the "half" hypothesis is incorrect

Why didn't I wait a month...  xD, I doubt there will be impressions of Master-8 vs Master-9. I wonder what I'll be missing in this headphone output improvement :C

I couldn't resist bugging Kingwa about sonic improvements over my Master 6:

 

Dear Bill,
The Master 9 is pure class A amp.
Its sound is a little richer on low and mid  .
In my mind the Master 6 don't want upgrade to the Master 9, the different not much, but the used master 6 sale price is much different to the new Master 9.

Yup, see compass spec www.audio-gd.com/Pro/Headphoneamp/NFB1033/NFB10.33EN_Specs.htm
The output at se is not remotely half of balance output. Don't ask me why though.

Oops, sorry, I meant nfb 10.33
