I've had a lot of B&O TVs and, on balance, the most impressive for me is the BV12-65. Not a single issue or problem since it was installed, superb smooth picture and solidly-made.
Only issue is the centre speaker, which is very basic.
For us a worthy upgrade from the BV5 would be either the BV12-65 (no problem with a bit weak centre speaker - se have BL5 as front speakers) or the BV 11-55 or the Eclipse. A balancing act between design, picture quality and usability (ML multiroom) 😛.
