As far as my little comparison on the 3910 and sp 1000, they both have the blacker than black bug for hdmi/dvi connections.
I checked for macro blocking, and found no objectional excessive macro blocking in movies that definitly show it.
The 480p was great for both players, but the 1000 made movies such as Unbreakable, have a smoother background throughout the film and offered the same great detail as the 3910 at the same time.
Audio comparisons were all done in 2 channel whith the 1000 having a more laid back soundstage and more body whithin the soundstage.
The 3910 initially sounds pretty good,but I would say its on the bright side of neutral for redbook and sa-cd.
The 3910 did not handle complex music as well as the 1000, and also had a slightly lean sounding midrange.
I don't listen to much dvd-a, but I found the 1000 too laid back as compared to the 3910 for dvd-a, and would pick the 3910 for that format.
I think the 3910 is a better player (other than build) to the 5900.
It offers slightly better video whithout excessive macro blocking, and good sound for the money.
If I had tried the 3910 first, I am sure I would be happy whith it, other than the hdmi/dvi btb problem.
Whith the 1000, it is worth the extra money for build, smoother film image and the neutral sonics, but it also has the hdmi/dvi btb problem.
Why can't these companys get this right?
