The Magni can supply 1.2W into 32 Ohms, the X1 being 30 Ohms. I'd like to have an affordable amp that goes well with the X1 and also allows some possible more power hungry cans in the future.
The synergies between different spec amps and headphones with different sensitivities/current requirements/etc are a bit unclear to me... Can a high power amplifier really be too powerful for a given headphone even if the output impedance is low?

Head-fiers around here say that the volume on the Magni scales up pretty fast and at the lowest levels there's some channel imbalance so it isn't really suitable for low impedance, highly sensitive cans.

I power my X1s with a Lake People G109 (over 2W @ 50ohms) and it works perfectly fine.

That's good to know - I'm seriously considering a G109 in the future.

The specifications say the maximum power input of the X1 is 500 mW, so anything beyond that could damage the headphones. I don't know for sure though. These are very efficient cans, so you don't even need an amp. Consider an amp when you actually do get more power hungry cans.

Driving the X1s to 500mW would push the sound pressure far beyond any safe listening level. You would have to crank up the volume knob recklessly and you would lose your earing long before reaching the max input power.
To achieve that, one needs to be mad or plain stupid. biggrin.gif

To make a clarification, the infamous picky AKG K701 can withstand a max input power of 200mW and you can drive it safely with a Schiit Lyr. Probably it wouldn't make the best match SQ wise but we are not talking about that anyway. ;D

Hmm, I'll forget the Magni then. So, what would be something affordable for the X1? The Asgard, perhaps? It's exclusively mentioned that it's excellent for low impedance headphones.

That is based on the comments of some users.  In reality, though, the Magni is and awfully good performer and it's really hard to discern a channel imbalance at lower volume levels.

I have MAgni with X1 and it's perfect

Actually that's good news. smily_headphones1.gif
Now I'm even more eager to hear the Modi/Magni combo myself. ^^

Checking Amazon daily to see when that listing finally shows up. I want these. Badly.

Not happy enough with the K702 Annie? wink_face.gif

post #686 of 4951
Completely happy. The X1 is actually what I'd consider giving uip the HE-400 for. The Annie is not going anywhere.

I hope you can get it soon! I'm looking forward to your impressions about it against the HE400 and the Annies

I love mine, but so far I could not spend as much time with them as I wanted.

post #688 of 4951
Me too. I'm mostly worried about the headband size. My big head... not sure it will fit.
post #689 of 4951
Philips seems to move at a glacial pace, release them stateside already dammit!
post #690 of 4951
Supposedly later this month. I'll give them until mid-Feb though.
