I've watched Stone Cold...well...I think it's better than the perf. in AX. Kaori&Wakana did better. I think they sound more tired&weaker in AX. Yuriko is sooooooo..... awesome....!!!!!&Keiko also did a good job.
As for Yuki's voice, I think the voice we heard is the pre-recorded one, but I don't think she tried to lipsynch. For me, it seems like she did sing along the girls but her actual voice wasn't recorded in the video. (It's the same as Kaori's video from Music Energy. She sang it live but they opened her recorded voice in the video....Orz..) The audience in the hall would hear it but not us.
To think about this, now I'm not sure that what I heard from Yuki in AX is the prerecorded voice or I really heard it from her mic, because I was so excited from seeing her singing that I didn't notice that it's really from her or from the recorded track. Well...if she really sang, but her mic was turned off, the audiences in the hall would hear only the prerecorded track.
BTW, the parts that you see Yuki 'sang' in this video are different from what I've seen in AX. I remember that she just sang with Yuriko in some Kajiurago part, not along Kaori's&Wakana's lines like in this video. So my guess is in AX, she did sing it, but in YK live9, she just sang along for fun and didn't turn on the mic, or the video we watched didn't record the voice from her mic :). (In the latter case, it means only audiences in the hall can hear her, but not us...:(.)
I think Yuki might do that because she usually said in the past interviews that she loves singing along with her singer but she was worry whether it's ok because she isn't a singer. I guess that she may sing along just for fun but don't want to publicized her voice... (Just my opinion...:).)
Have just finished
Parallel Heart Umm...Wakana... There is a part that sounds like... I don't know how to describe... but it isn't the off-key or sth. like that... like her voice didn't come out properly... just an accident, I think..but Wakana looks a bit...like she's struggling while singing....:(.
Edit: Finish watching...Orz
Parallel Heart: Besides Wakana's struggle-like singing, I found that it's quite fine. Keiko sounded a bit awkward in the bridge and Yuriko was just good... Since it's the first song of the concert, I feel like everyone hasn't reached their best yet... Hope that everyone would do better and better...esp. for Wakana whom I've noticed for a while that she's a kind of a slow starter who is not that good at the beginning, keeps improving when some songs pass by, and is always the first one who uses up her energy...Orz..(Hope it wouldn't happen..too often...)
Here we stand in the morning dew: Yuriko sounded so awkward at start, but I think that after the first hook, she did a good job. Wakana's voice sounded a bit too outstanding in the chorus. Using head voice to sing high notes can show the ability of the vocalist, but I insist that I prefer to hear Wakana using her soft falsetto instead of piercing head voice for the chorus.. (Just my opinion...)
Kaze no Machi E: Ok..I think I'm not impressed with her Kaze no Machi E. I'm not impressed with the original one, but I think Keiko's live singing was also not as stable and powerful as usual. Sorry again for Wakana... I still think that her voice didn't blend well with others. Love Konno's violin solo so much...!!
Himitsu: Oh my god....it's one of my favourite song from Yuriko....!!! I feel that in this song, Wakana&Kaori duet on the bridge blended so well..... What I disappointed from this song is the guitar solo which isn't loud enough...
Dreamscape: Not my favourite song but I think Kaori always sings it so good at live. But in this live, I think she's off at some parts..
, but it isn't that outstanding for me... Keiko did a good supporting role in this song.
MC1: I like Kaori hairstyle&dress today....lol. She looks so elegant..!!
Houseki: I think Keiko did far better than Kaze no Machi E for this song... except some parts that it sounds like she shouted the high note out.
Mizu no Akashi: It's fine until the part before the first hook...and then..... Uh... it seems like I found a brand new problem for Wakana beside shorter legato, off-key, and thinner voice... Like in PH, sounds like her voice didn't come out...
Michiyuki: I like the way that she sang it in the more emotional way in the hook. Kaori carried out the feeling of the song really good..even there were some mistake, but the overall performance is good enough to look over those faults.
Sayonara Solitiare: Kaori did really good job... I prefer it to the original version. I agree that the start sound a bit unfamiliar... I feel like Keiko tried to put the dynamics (???...I mean she tried to keep increasing&decreasing the volume of her voice to give some feeling to the song) into her singing but it wasn't work, both for this song and Kaze no Machi E. Love the violin solo and Yuriko's Kajiurago.
MC2: Yuki was so cute when she introduced Jr.!!! lol. I notice that Wakana got so much rest in this live.. at least, I guess that Yuki also concerned about her condition.
Hikari no Yukue: Wakana did quite fine....(after taking some rest...maybe...) But the string that popped up during the first slow part of the song sounded so random... All other girls chorus were so awesome esp. Yuriko. I accept that Wakana did better than I expected.... good job..!! The Kajiurago bridge are also awesome..!!
Hanamori no Oka: As expected...lol. BTW, I love this song even I think in this live, it isn't as good as the previous ones I have seen so far.. Kaori sounded weaker in this one. Wakana's English bridge also sounded weak, but I think she must use so much energy in the previous song. Love the violin as always...
Gin no Hashi: From the bridge in Hanamori no Oka, I guess that it would be a tough work for Wakana now.. She sounded tired, not very bad..., but for an energetic song like Gin no Hashi, it made the song lose some feeling.. Let's say that it's quite fine, but not outstanding.
Synchronicity: I barely heard the violin at the beginning..T^T. I also like this version of Synchronicity.., it may sound weaker, but it gave me another feeling, and I love both..^ ^. One thing that I don't like is some parts that Keiko sounded like she's a bit off-beat, but it isn't as obvious as in some previous lives that she did the same mistakes. Yuki's bridge sounds so awesome..!!! One of the highlight of this song...^___^.
Stone Cold: Ok...it's really better than in AX..!! Everyone sounded so energetic and did quite good. But I think that in this live, the instrumental solo has too low volume...T^T. The part after Kajiurago bridge is so awesome..!! Yuriko is so amazing...!!!
Everlasting Song: Beautiful violin..., but well...without the extended Kajiurago, I didn't pay much attention in this song. However, Wakana sounded so strong in her part. Kaori's voice sounds a bit unpleasant for me...esp. her high notes and the part when she danced.
Hoshitsuku: Are there some problem with sound system or sth...??? Because the prerecorded voice of Wakana in the intro&high-note parts of Wakana's&Kaori's live singing sounded so strange and it almost made my ears bleed...T^T.... Wakana herself also sounded unstable
Distance: I think Wakana's voice wasn't strong enough to dominate the chorus. The other girls did so well in the chorus esp. Yuriko. Sorry to say that..., but everything sounded so messy esp. when Kaori gave her chorus part in the hooks. (Her voice was filtered in the recorded version, so..when it comes to live....Orz..) I don't like Keiko 'dynamic' singing style in her solo. Wakana&Kaori also did not well in their solo parts... But I think Kaori's bridge in the part that she had a duet with Yuriko was so good. Umm... I may agree with Grunty for this song... it sounded quite good when Wakana wasn't around...TT^TT.
Eternal Blue: Err... Kaori&Wakana were even worse than in Distance.., but it sounded better because the chorus wasn't that strong in this song (to make it clear..it's mostly 1 main:1-2 chorus in this song, while there are even 1 main:3 chorus in Distance), so even the main vocalists were a bit weak, they weren't dominated by the chorus. BTW, the bridge was awesome, and seriously, I ADORE Yuriko..!! I think she did some mistakes as well but they weren't that outstanding. Love the violin parts....^ ^. Can't imagin these 'generic FJ songs' without Konno's violin..lol.
My favourite: 1. Himitsu
2. Michiyuki, Hikari no Yukue
3. Sayonara Solitiare
4. Synchronicity
Well...recently, I got a good(?) news for myself...Japanese government is planning to allow Thai citizen entering Japan without Visa.....(=easier to go there&lose money.....time to apply for FJC..??? lol.)
My dream is to buy, one day, a CD with Kalafina's covers!! *W*
Oh, and as usual, I always blame the PA system. 
It was enjoyable to watch, though there are a few disappointments, but thats normal. 
etc
