As I mentioned in another thread I compared my 2 DVD players this weekend.
IMHO
The test wasn't blind, but I used items I had multiple copies of so the switching was immediate.
SACD
I think the Sony is a better SACD player. It seemed that the Sony had a little more detail & better clarity. If the Sony was $60 more then the Yamaha I would definetly buy the Sony. However, I don't think the Sony sounds $300 (actual price difference) better then the Yamaha.
The discs or songs I used for the SACD comparison were:
Bob Dylan SACD sampler.
Anna Netrebko - "Song to the Moon" Wiener Philharmonic
Anne Sophie Mutter - Romanze fur violine und Orch No 2
Aerosmith - "Sweet Emotion"
redbook CD
If there is any difference between these 2 players on redbook CD I could not hear a difference. I am completely happy with both players. Not that I have owned many players & nothing over $600 but both these players are the best redbook I've had.
There have been complaints about the Yamaha defaulting to PRO-LOGIC II when it reads a CD. While there is no way to switch this default (at least that I couldn't find) the PLII is only output through the MULTI-CHANNEL OUTPUT, not the 2-channel output. If you switch your Reciever to 2 channel direct you will hear the normal stereo mix. The remote does have an AUDIO switch button if you want to hear the stereo mix using any multi-channel output.
DISCS
Def Leppard - Vault
Mars Lasar - 11th hour
DVD-VIDEO
I couldn't do an immediate A/B test of the video signal, but I watched "Resident Evil-Apocalypse". This movie has many night scenes & a lot of high speed action. I never found the picture lacking.
DVD-AUDIO (C750 only)
This model is replacing a Mitsuibishi DVD-A player which had problems on 5 DVD-A discs (including locking up on a Anne Sophie Mutter disc to the point where the player had to be unplugged to get it turned off & the disc out).
I was happy when the store model played all the problem discs. I was euphoric when I heard it at home. This player revealed sounds I never heard on the Mitsuibishi with just about every DVD-A I own. Prior to getting this player I loved both DVD-A & SACD, but I prefered SACD. SACD many times has WOW'd me. I can't count the number of times I've looked up from reading or playing Solitaire because I thought the (insert instrument here) player or singer was in the room with me. The female singer on "Let It Grow" from 461 OCEAN BLVD is one example of this. I never got that with DVD-A with my old player. While I still prefer SACD, the gap is now pretty small & DVD-A has now WOW'D me a couple of times.
Player negatives:
Remote does not have a dedicated FF or FR button. If you want to speed up the song or go back to catch some dialogue in a video you have to hold down the track button. The remote is almost a little too basic & there is plenty of room on it for fast-forward/fast-reverse buttons.
Changing discs in/out of the player. While it is very easy to change 4 discs using the EX-CHANGE button, changing all 5 at one time using the OPEN DRAWER button isn't as easy. The carousel does not spin when open so 2 of the 4 discs are half covered by the player itself. I plan to use the EX-CHANGE button exclusivly in the future.
Player does not automatically go to the next disc when a DVD-A disc is done.
I'm not sure if any DVD-A changer does this or not, but it kind of defeats the purpose of a changer if it doesn't go to the next disc.
Player positives:
Great DVD-A & CD
Very good SACD
Universal player $300 or under
Dolby Pro Logic II (my receiver doesn't do this so it was an added bonus for me).
It seemed like you would not need to have a moniter hooked up to this player in order to access the hi-rez m/c track. Every disc I just hit play.
I think someone asked about me to check how long the player took to change & load a new disc.
disc change CD to SACD 14 seconds
disc change SACD TO SACD 10 seconds
I didn't actually time a change to/from a DVD-A disc but it seemed in the same ballpark.
I think the C750 is a great all around player, especially for the money. If I didn't already own the 555 & I could afford only one player I would go with the C750. The loading problem, poor remote & not quite as good SACD sound quality does not = the lack of DVD-A & the doubled price of the 555 (I believe the list is $299 vs. $599).
