Probably me you are referring to. I have had it for ten days and I can now say that I think the Master-6 drives the HE-6 with ease, finesse and power. I would add holographic imaging and stellar transparency. To me this is definitely high end performance.

 

At first it had increased bass and treble, but now it has found itself - relaxing the extremes of the audio spectrum.

After discovering this, I remembered that someone here on Head-Fi saying the same thing about how Audio-gd's products change with burn in the first days.

 

I have a LC Audio Sidewinder pre amp and LC Audio ZAPsolute Mk 4 power amp set to compare it to.

When attaching the HE-6 to the LC Audio power amp and using the Master-6 as pre amp the difference is subtle, but in favor of the Audio-gd.

Master-6 hp out delivers more transparency and better imaging precision than Master-6 pre out to ZAPsolute (HE-6 attached to speaker tabs).

The Master-6 as a pre amp is clearly better than the LC Audio Sidewinder pre amp.

This is obvious when using hp out of the Master-6 versus the LC Audio amp combo (speaker tabs out), because then the difference more clearly there.

When I read the Audio GD site it's not very clear. It makes me feel that the Master 6 is not as much class A as the 5.

 

This part for example :

 

 

Power Consumption

45W class A @240V or 120V

45W idle @240V or 120V

 

or that :

 

 

Headphone amp Output Power 
 

50 ohm:   1700MW
100 ohm: 2400MW
300 ohm: 1200MW
600 ohm:   600MW

(Balanced , Class A)
 
40 ohm:   9000MW
50 ohm:   7000MW
100 ohm: 3500MW
300 ohm: 1200MW
600 ohm:   600MW

(Balanced , For >20 ohm headphones)

 

Should I order the Master 6 for HD800 ?

 

Thanks for your help guys.

 

Yes, you are right: the Master-5 and -6 are identical except for the last headphone amp step - as seen in the above power figures.

Both amps run fully balanced and class A all the way, except the last headphone amp step in the Master-6. This is because of the extra power it is producing.

To drive the Sennheiser HD800 - forget the Master-6 and go for the Master-5.

The Master-6 is only for extremely low sensitivity headphones (read: HiFiMan HE-6 and the like).

Good luck!

It is truely a heavy headphone / pre amp. When I lifted it I couldn't believe how heavy it is.

Keep those impressions coming! Looking forward to more impressions on the Master 5 & 6. It is on my shortlist as well.

Thanks for the impressions LarsHP, I see you have the Ref 7.1 in your signature. Is that the source your were using??

Yes, using the ACSS connection between the two Audio-gd boxes.

Has anyone compared or heard both the master 5/6 & the DNA Sonet? 

I Can't decide.

post #144 of 876
I just ordered a master 5.

20 days to go.

Great to read some impressions on the Audio-gd Master-6 and kind of funny the attention is not that big on this Master amp . Does the Master 6 get as hot as the Phoenix, it sounded like you could cook an egg on top of it.

Both are warm and possibly hot but not ever that hot. You could not burn your hand. They are class A which run hot by nature. The Master-5 might be a little cooler from memory.

Any more impressions of the Master 5 / 6?

Hmm. I could add that the K-701 sounds less thin in the bass and the piercing treble is gone when plugged into the Master-6.
post #149 of 876

Well an m-Stage can do that for the K701 as well lol. What amp are you coming from with the AKG?

The M-Stage! I bought it because many people said it had a good synergy with the K-701. The M-Stage has warm and transparent mids that suits the K-701 well. However the bass was thin and the treble piercing sharp with that combo. When I use the same cd player and interconnects to the Master-6, the sharp treble is gone and there is a little more bass.

I should add that I don't have the M-Stage anymore, but when I had it it was intolerable with my cdp and K-701, which is not the case with the Master-6 between the two. I am not saying that the K-701 sounds like a totally different headphone, but now it sounds noticeably better balanced via the Master-6.

I think this is due to the same effect as when the HE-6 is underamped, even though the K-701 is much easier to drive of course. In other words I think that especially somewhat bright headphones in general will benefit from being driven by more-than-one-should-think powerful amps. In this case the M-Stage is about 440mW IIRC, and if the K-701 is driven by a - let's say - four times more powerful amp, then it is audible as in taming the treble and strengthening the bass. I would think that the Schiit Lyr would be a good combo for the K-701 because of this (and the price is in the league of the phone). I saw someone here on head-fi who has that combo recommending it for this very reason.
