The Avant and the BV7 shared a number of core features.
Both for their time, had unbeatable world class pictures. The 11 has a very good picture, but it is not in the same league as the new OLED Tv's by Samsung and LG, which both have reference quality pictures. Note: i'm not talking about UHD/4K here. I know people will mention pixels fading on OLED over time, but I have had to put up with dynamic contrast in the evenings since day one, so that just falls on deaf ears.
The Avant and BV7 both had DVD/Bluray players built in. The BV11 doesn't. I know you like Apple tv, and so do i, but it isn't as good as Bluray. Why can my 1Kg laptop have a BluRay player, but my 50 Kg TV not?
The Avant and BV7 had amazing sound which was world class. The BV11 has very good sound, but is naturally limited by its lack of volume. It needs a subwoofer(£1700)!
Naively when i bought my black BV11 i thought it would come with a black base which is not the case! I have a black BV11, with a red fret, on a silver stand, next to a white Beolab 14 sub(for the lack of bass and distortion), next to silver satellite stands with red frets. A complete visual mess.
The Avant and BV7 were black or silver(mostly) Cool and subtle.
I have owned and still own an Avant and a BV11, and recently a BV7. But the 11 in my eyes, does not inherit those aforementioned core qualities that the Avant did.
