Posted Sunday impressions in anime thread again, took some parts and still a bit general and unserious at times. Posting in few other threads more tailed impressions.
T.H.E. Show today was a lot less uneventful than it was Saturday. Mostly was hanging out with people and checking out some uninteresting speaker systems. Didn't take many pictures anyway as I was mostly repeating some booths. Some new things, some neat things, some impressions.

He-400s pads, very velour.

New thing, JDS Element

My o2 for scale

O2 and x5 for scale

Usb in, rca in (I think), gain switch, power button, power cord in

So it is square with rounded edges, volume knob is is a circle. Tad daa~ But seriously it is a dac amp combo and I turned the volume knob to around 10-11 o'clock and that was plenty loud enough for me. Iems I was hovering around 9 o'clock with my noble 4. Sound was very nice and I enjoyed it a lot. So it is $350~ iirc. Dac is very similar to the dac in c5d and amp is very similar to the o2 and c5 in the Jds Labs guys words. It was very cool and minimalist desktop amp/dac, solid metal finish and smooth volume wheel. I liked it.

Shiny woo amps and the he-1000 in the special woo room.

Shiny abyss to the shiny woo monoblocks that was also going to a shiny sony home media player type of thing. I can at least now say I have heard a $22k audio setup. It sounded alright.

I thought this ad in the hall was funny.

Out of focus fiio x7 picture. It wasn't working or anything but an early model showing off a big touchscreen and on the bottom of the unit a replaceable amp system in the works or such. Don't remember everything he mentioned about it. Played with the x5 ii and then with the e12a with my x5. E12a is good with iems like it was magically designed for it or something magical like that. Also had the new renamed fiio amp dacs. The successor to the e07k and e6 with changed names and shapes. Didn't get good pictures of them.

Then spent the rest of the day at questyle with Andre and ended up inadvertently working there for several hours. Older QP1 model internals, slight changes since then on newer models. Heard some interesting stuff from questyle and talked to many people from questyle. The questyle QP1 and QP1r I listened probably many many times these 2 days on. Probably my favorite new dap now and really interested in getting one when they are ready in production.

The Shelby that was in the room during break down time. The owner drove it out the back doors and the whole room smelled like gasoline. It was very American and patriotic.

Hung out in the questyle room afterwards with Andre and moe. Limited time they were going to sell the show computers for people that were to buy one of the dac or amps. Think they are still doing the deal now.
But in the questyle room I talked to the developers and showed them my x5 with its custom firmware, showed then different case, ways to stack fiio daps with amps, my amps, general feedback and learning about the QP1 and QP1R. Nice dudes and we went to dinner afterwards with warren and mercer along with questyle.
Hifiman he-400s impressions
Headband is very nice and comfy, weight is a lot less than the he-400 and with the headband it is a whole lot more comfy. Cable as others have mentioned has been changed to the he-1000 connectors and the cable this time is pretty nice. Pads are also not the old he-400 velour or the focuspads but an entirely new earpad. Overall comfort and weight is very much improved but that has kinda been the case since the 560 and 400i.
The sound is a lot closer to the 400 than the 400i. Strong bass presence, more so midbass but did extend pretty well into the subbass. Wasn't hearing upper recession but environment was tad loud to completely accurately tell. The treble wasn't as forward as the original 400 and wasn't hearing sibilance on tracks I playing around with. Very nice headphone and those I talked to liked it also and some weren't a fan of the original 400 or the 400i. Prefer the 400s over the el8 from what I heard of that phone.
Questyle QP1 and QP1R impressions
UI was absolutely easy to use, took just a quick glance at everything and then I was all set to work. Took out my micro sd to put it in the unit to listen to my personal music for reference with my noble 4 and it sounded positively wonderful on both the QP1 and QP1R.
The QP1 I believe is in the top picture, the corner icons has haptic feed when pressed. The scroll wheel is metal and super solid feeling unlike my x5's tad flimsy plastic wheel. Response time in comparison to the x5 was very fast. At the end of day Sunday I showed the developers my X5 and when they tried to use it they were surprised how there was some lag between pressing a button and the action occurring.
The volume knob at the very top of the unit was on a tad looser side but when I asked them about this Questyle said they were aware of this issue. The factory that was making prototype shells of the unit made the volume knob hole too large and thus led to a loose wheel which during the actual production run will have a much more solid feeling volume knob.
Sound wise I had my fiio x5 for a-b comparison and found I much prefer the sound quality of the Questyle over my own x5. I had tested and played with the astell and kern daos earlier in the day before trying the Questyle daps and thought sound quality in my opinion was around the ak 240 and the ak 380 was only tad better sounding.
At the end of the day Sunday I was talking with the questyle guys working on the QP1 line. I talked about the times and locations I used my dap. How the stacking for the fiio daps looked with amps on their backs. Showed my custom UI on my x5 and the general features on the unit, my general complaints and what I felt the x5 did well. I walked through some of the history of my experiences with daps, what the x5 did wrong in the beginning and how firmware patches starting fixing things. Discussed possibilities of custom firmware like that of the x5 on the QP1 line. In general some popular portable amps people are using. They were very responsive to feedback I was giving towards my unit and their unit and telling me their general design philosophy. Questyle is just a fantastic company with many great people working for them and when the QP1 is ready I am very much so looking forward to the QP1 or the QP1R.
Some personal shoutouts I want to make.
Warren and Mercer big shoutout for making headphonium possible! Was only planning on coming Saturday but I am quite happy that I went Sunday as well.
All those at Questyle! I enjoyed talking daps, amps, dacs, headphones, everything! Real big shoutout to Gary, was fun talking and helping around with taking apart the booth.
Nina from from Wywires! Saturday night was plenty for fun and thank you so much for the drinks and in general for being so swell!
Jeff at Hifiman for putting up with my antics.
And last but most certainly not least Moe and Andre! Fun hanging around, talking audio or just in general talking. Good to catchup with everyone and hope to see everyone soon~
(Also Andre keep me informed with the he-500!)
