So I've had the H10 for several days now. Very brief initial impressions: Between the HE-500 and the LCD-2F, the former is more striking with the H10. By that I mean I think the HE-500 has benefited more from my acquiring the H10 than has the LCD-2F. The LCD-2F + H10 is still a very fine pairing. But I'd already heard the LCD-2F well driven. My previous experience hadn't really shown the HE-500 off. Anyway, I hope to have something more detailed to say soon.

  I think so, without the high cost. It is also good looking and even connectors are high precision in shape showing attention to details. I researched before buying, to pair it with HD800 and H10 exceeds all of my expectations by a high margin. I could not save money by going any other than HD800 headphone as I auditioned LCD3, Sony Z7 and others and realized that some day I had to buy it.  same for PHA-3 as it is most versatile, having ESS chip, battery powered and can be used in many different setups and even has balanced amp out. 

 
From what I'm hearing about the H10, it definitely qualifies as not being a waste of money.  I consider lesser purchases, at or below the likes of the JDS Labs O2 or ODAC, to be representative of where you will later find your money to have been wasted.

Originally I’d intended to say a bit about the LCD-2F + H10 pairing; I may still get around to that. The LCD-2F has been my favorite all-around headphone for a while now. I bought the H10 after reading this thread on Head-Fi; I’d discovered this thread by association when researching the Cavalli CTH. (FlySweep is the salient link in this chain). The H10 looked like a suitable amp for my HE-500, I thought, and the price wasn’t prohibitive. In fact, it was encouraging. Since the H10’s specs indicated it should pair well with planars generally, and since planars are my preference, I pulled the trigger.
 
Rather than the LCD-2F, I’d like to focus on the HE-500 + H10 pairing. This is because I think the H10 drives the HE-500 better than any other amp I’ve heard. And drives it by a larger margin than whatever is the LCD-2F’s with the H10 relative to other amps. The previous champ had been ALO’s RxMk3B+, but ultimately I found the combo fatiguing for longer listening sessions, and best in short bursts. The RxMk3B+ was, I’d wager, a tad aggressive. Still, I miss that bass boost knob.
 
The relevant listening with the H10 was done with the +6dB pre-gain setting enabled. I agree with No_One411 that it’s an excellent setting for the HE-500.  The HE-500 itself was outfitted with the newer Focus Pads (not the A version) which come standard on the HE-560 and HE-400i. I’ve always known that there was a reason I’ve held onto the HE-500. This is it. I find it difficult to give content to my claims without appealing to specific music. Lapalux’s “Cousin If” from the Many Faces Out of Focus EP – my current favorite single test track for headphones - has never sounded better. Lapalux’s Nostalchic is seriously important. It’s the album I thought it was.
 
For the rest of the post, I want to draw attention to certain aspects of the pairing. My hope is that this helps others to gain a better understanding of the H10, as well as the HE-500. Either one is a reason for owning the other.
 
The extension and the timbre quality of the bass is one of the more striking qualities of the HE-500 paired with the H10. The LCD-2F is often touted as a basshead’s headphone; while it certainly excels low down, I tend to think of the LCD-2F as a percussion headphone. I love it with e.g. Aphex Twin. When the sub hits on the HE-500, however, I’m liable to think the walls of my apartment are shaking. E.g. “Sphynx” on Etch’s Old School Methods EP. But there’s zero apparent distortion both in the mids and in the bass regions above the sub. On the contrary, I think the extremely low and tight bass contributes to the naturalness of the HE-500’s mids.
 
Now, of the headphones I’ve heard, the HE-500 has the widest apparent soundstage. It also has one of the apparent deepest. This can be very interesting when listening to music that has large tonal blindspots, like dubstep, since a pleasant sense of airiness comes through. I’ll return to this idea shortly. But it can sometimes sound like you’re present at the music – i.e., where it’s happening – spatially located, as it were, with respect to its source.
 
In other words, the HE-500 has a remarkably transparent sound signature. A headphone’s sound signature is transparent, I take it, when it approximates the sound of loudspeakers. People have claimed that the LCD-2F is extremely speaker-like, but I’ve always thought it sounds like nothing more(!) than a really great pair of headphones. Of course, I love the sound of great headphones. Who doesn’t? But sometimes great headphones (can) sound like great speakers. Which means they (can) sound like the real thing.
 
In the present case, the H10 makes my HE-500 sound like exactly that. This impression is created, I think, by the combination of the HE-500’s tremendous sub-bass imaging and the natural, centered and vaguely forward mids. Because of the width of the soundstage, an impressive sense of space is created in the stereo image. There’s greater separation than with, say, the LCD-2F. For these reasons, and for the one listed above, the HE-500 is an excellent headphone for dubstep – broadly understood. And particularly with Volor Flex’s Sabo. I feel as though I’m hearing the music in, say, a subway tunnel. That the HE-500 has a black background when driven by the H10 (even with the +6dB boost enabled) means that this sense of space is in no way obscured by the headphone.
 
Moving forward, I’d like to hear the HE-560 with the H10. Given what FlySweep had to say, and what I’ve myself heard with the HE-500, I expect I would like the pairing. And I still want to say more about the LCD-2F + H10 pairing.  Oh, and I hope to have the Cavalli soon as well!

Hey guys....the H10's DAC twin called the X12 has finally arrived. Pollychen will be posting it soon on his ebay store, but a few others have already beaten him to the punch. Take a look at this listing with lots of info and pictures.  Not only is it cosmetically now the twin of the H10, the X12 also has some significant improvements on the inside.  I am particularly pleased to see that there is a new discrete analog output stage that they say was developed for their soon to be released X20 flagship... hmmm....now that's got me really intrigued! I'll bet this one is a dual chip model sort of like the X-Sabre.

I'm going to be ordering one of these soon so I can do a direct comparison with my Aune S16. By the way, the S16 is soooo good that I will be very surprised if this new X12 sounds appreciably better.

Nice specs. Hope it delivers like the H10. For 530USD, it will be a winner.

More news from Pollychen, aka, our Gustard guy.  Apparently, much was done with the new model on the USB end, including a new daughter card with I2S and USB with a new XMOS chip..  Here's the good news - for those of us who don't care about using a computer as a source (I'm talking to you too Swannie, my OZ friend) the modular approach has allowed them to produce a lower priced X12 without the usb interface.  I am waiting on a quote for this stripped down version and if it is significantly less (I'd say at least $70 would do it) then I'm going to put in my order this week.
 
Pollychen has his add up on ebay for the standard X12 version, so I'm going to show him a little head-fi love ----

His price is a little higher than the lowest listed one, but the main difference is that Pollychen ships DHL expedited and the others don't. That, and his proven track record is more than enough for me.

Any idea how soon is "soon"?

+1. The fact that I received the amp inside of a week when it shipped from China is amazing. Pollychen goes above and beyond.

If you are asking about how soon the alleged X20 will be available, I have no idea. They just said that in the add copy for the X12. I didn't ask Pollychen about it because I think I will be satisfied with the X12.

The guy is excellent with communications too, so I have no qualms whatsoever in supporting him.

And I just pulled the trigger on an X10 last week! I am sure I will be happy with it. I will report back when I get home from my work rotation and listen to it. Cheers to all from the "bush" in Oz.

  Has anyone tried the H10 with low impedance headphones or IEMs?

Low impedance + high efficiency? The HE-500 is low impedance. I've thought about trying my Amperiors on it, but haven't yet. Those are 18Ohms and can be easily powered by my HTC One. The H10 does have a -12dB pregain setting.

I've done -6 setting with my UERMs and they work fine. Not as much play with the volume as one would like, but it sounds fantastic. 
 
Do have to switch down to -12 for the Noble 4s though, and it does push the brightness to something that I wouldn't want to listen to for an extended period of time. 
 
Not much hiss, at least for me, especially when you have music playing. You notice a little when idle. 
 
Hope this helps. The amp works best driving planar magnetic headphones. I'm still much happier with it's performance with planar magnetics over the HD800.
