Hello Mikydo,
I don't really think the 1930 can outperform the 1400 in performance, although it does in specs (HDMI, progessive scan, scaler, etc, which were unusual by the time of the 1400). Of course it is not a prove, but a hint: just look at the MSRP of both, and compare the quoted specs of Denon. Moreover, both have 2 MB buffer for layer change, and unless they do it much better now, it must be noticeable. Actually, it might be better reproducing the image, since it uses 1 bit more Dynamic, but look at the audio part (which for me is very important): the 1400 has different d/a converters, and I don't know if the change is for good...
otherwise, it does have all specs I would like (if the layer change is not an issue...).
I might be talking nonsense, and 350 euro now buy you more than 550 euro three years ago... But it is just I don't have any objective, real life experience input.
BTW, there are two or three threads discussing problems with the 1930...
I hope you can share with me your experience testing the 1930, specially if the layer change is detectable.
Regards,
Alberto
