  Any one uses G103 with Hifiman or Mrspeakers headphones?

 
I used to before I upgraded to a G109.
Sounded fantastic with HE-5's and (my favourites) HE-4's.
The G109 + HE-4's has ended up as the perfect system for me and I have finally stopped looking for anything else.

Thank you,
Any particular change I sound signature going from 103 to 109? I don't need much power for 400i and Alpha dog, and 103s specifications seem quite adequate.

 

[0rangutan]

No obvious change in signature.
I mostly bought the G109 to stop any nagging doubts about whether it would sound much better than the G103.
They are very similar and both are bargains at the full list price.

Ok, could you share sentence or two comparing them to Lyr ?

 

[0rangutan]

They sound similar but slightly better than the Lyr with the same level of control but a smoother sound.
Far more importantly, they won't damage your headphones like the Lyr can.  The Lyr is poorly engineered with no start up protection and using one blew a driver on my Beyer T70's.  Won't ever buy Schiit again and in particular I would strongly advise against using the Lyr for this reason.

I don't think that this problem with the Lyr still exists... nevertheless I'm sorry to hear that it killed your T70.
 
For me that way one reason to choose the G109P: it was the only model that had protective relais in the output.

They put a relay on the lyr's but lots owners complain about them humming or hissing, LP amps are dead quiet

anyone here have experience with g103s and hd600?

I have a G109S an it's dead quiet too but when I adjust volume it totally hums, even if I just put my hand on it.  Is that normal interference with the potentiometer?

My G109P is totally quiet even when adjusting the volume. I think yours is not normal. Most likely a grounding issue?

I had a same issue with my 109P when I use RCA inputs. Weirdly, It has been solved by using XLR inputs. Ive been thinking asking about this issue to Freid, but not yet.

Well that makes me feel better. Yeah I've only ever had a cmoy amp and a fiio e9 before the lake people. Both did the same thing with the potentiometer but they also weren't dead quiet ever either.

I'm using my G109-S with rca inputs and I get no noise when changing volume and overall the amp is 100% silent even at max volume (when nothing is playing of course).

Yes, sounds like an issue with electrical ground. maybe the ground is not connected at (behind) the wall socket? If so that can be a security risk, let someone check that. I don't think its a fault of the amp.

Absolutely.  My HD600's sound VERY good with my G103S.  It's actually one of the only SS amps I will let touch the drivers of the Senns.  It gives them a touch more energy but it doesn't try to alter that nice, smooth, neutral signature that the HD600's have.  Very, very good pairing.
