GUSTARD H10 High-current Discrete Class A output Stage Headphone Amplifier

[tvnosaint]

The h10 is designed after the violectric v200 from what I understand. That's the next model up from the 109 from lake people. If all that is true and the Gustard is cheaper...no brainer.

The H10 is not a direct clone of the V200 but they sure used it as inspiration. Highly recommend the H10 with planars very time it comes up on Mass drop I have to stop myself from buying a 2nd one to replace a Burson soloist SL for my desk set up.

Anyone bought from this seller ?

i am between Lake people G109-A and Gustard.
Gustard has better design (on papers) but the g109 is almost as capable in amping ,with great build quality and warranty support.

Never seen an official site for the Gustard  

Any bad quality issues for the Gustard that i should now about ? 

Be sure to pop the cover and make sure it's set to proper voltage.

I've come to the conclusion that I like the stock duals paired with the Burson singles. The dual Bursons seem to make things too smooth and also shrink the soundstage.

I'm still preferring the K7XX paired with the H10 and the HE-500 with the APPJ PA1502a.

Have you tried lme49720ha? I heard it makes the sound brighter. Maybe it will be a good match with the v5 singles.

I put the replacement dual v5 in. Immediately noticed an improved soundstage and weighted presentation. It's tight though. Also a little channel static and loss of sound for a minute twice. In one channel. Man I'm sick of taking this thing apart .im gonna give the h10 the deoxit/ fader treatment to see what's up. I'm wondering if having two opamps with different voltage tolerances may cause a problem .

I have not. I'm not sure I'd like a brighter tone.

Are you using right now 2 x SS V5-dual op-amps: an older one (abs. max. voltage is +/-15V) and a new one (abs. max. voltage +/-17V)?

Well, you said that the duals V5 made things too smooth. Haven't tried the 49720ha, but it's supposedly superior to NE5532 in terms of hi-fi I guess.

If they do have different tolerances, I would think the only problem would be in one that has insufficient tolerance.  The other would remain unaffected.  
 
What is "the deoxit / fader treatment"?
 
Update:
 
I figured it out - I had never heard of this CAIG product - http://store.caig.com/s.nl/sc.2/category.293/.f
            
Do you use this on the volume control of the H10 or on the op-amp pins or ???
 
I put a tiny drop of Deoxit Gold into each hole in my DIP8 sockets and for a few days thereafter, my Burson V5 duals were rising out of the sockets - just on the spring tension applied to each pin.  LOL  
 
This is what I've been using: http://store.caig.com/s.nl/it.A/id.1609/.f?sc=2&category=292
 
They never got high enough out of their sockets to interrupt the signal, but every time I sat down to listen to music I had to push them back down again - a distance of about 2mm. The lubricating action of the Deoxit Gold finally wore off, so they're staying put now, but for about a week, I was regretting having used the Deoxit.  
 
I can't say it made any improvement in sound, but I'd still recommend it as "preventative maintenance."

Yes, Burson sent one dual opamp as a replacement. I put them in and I have that nice sound back when it works. But it is increasingly intermittent. The left channel pops crackles and goes in and out. So it's time to take the hood off again. Switch the opamps to see if they are the problem. Apply the fader cleaner and deoxit the outs of the amp and plugs. I'll give the caps a good look over as well. The sound of these is incredible but I obviously can't live with the bad channel. All of this started when I put the op amps in.
Edit:
I've cleaned all the connections and that seems to have fixed the channel . Doh!. The simple things.

I'm a little concerned about those narrow sockets with the towering Bursons extending out of them, I expect they'd work lose if you transported your H10 very often just from the vibration and torque on the pins.  But I think some foam caps that would be pressed down on by the cover to hold them in place could be made if it was a problem.

The H10 isn't exactly a portable amp. I think they will be fine up to a complete drop of the amp.

I took my H10 to and from work quite a few times with the Bursons installed.  No problems.  I wouldn't mail the amp with them installed though.

I believe your "old" V5 is designed for +/-15V, so why are you still using it in H10? AFAIK H10 has +/-16.5V on it's rails, so I strongly recommend you to take out the "old" op-amp.
In case I didn't understand your setup, then sorry, but if you're using +/-15V op-amp in a +/-16.5V amplifier then...no other comments.
