The LX55 definately needs a new firmware - however I think the performance is very strong - despite the player only getting 4 stars - that was only for the sound - discussed with What hifi personally about it.
I have owned the LX71 and the LX54 before the LX55. I wasnt totally happy with the 54 so upgraded to the 55.
I got the 54 free with my LX83 and demo'd against the LX71 on my LX5090 - to me the 54 was much sharper and pqls sound was somehting I couldnt live without once I had heard it
I have since calibrated my LX5090 was not at the time of that decision - I may not have kept the 54, I am not sure, I also sit a long way away so my decision was based with that in mind - picture at about 13 foot distance
I get to see the LX08 quite a lot on a Panasonic 50G20 Plasma - same player as LX71 - its a great player, you get a very soft cinema like picture with big and bold sound- very dynamic sounding
However I find with the LX55 you get a better picture in most ways and the sound with PQLS is far more refined, and layered hard to describe this without hearing it. Its one of those you turn it off, think for a minute its better with it off, then always turn it back on again and leave it
Its a much faster player as well.
Plays most blu rays perfectly - the odd bit of lip sync in some I have noticed, its bad in some films which is a bit pants but no the majority of films, the odd ones
1 more firmware update and it will be hopefully perfect - the LX71 has had about 6 updates so it takes Pioneer a while to get it right I find. We are due one, every 3- 4 months
I found the Pioneer players to trounce the likes from Panasonic a few years ago - it could be very different now
I dont reget owning the Pioneer blu ray players, none of them they are all excellent
What dont you like about the LX71?
