I don't know.
I am a complete B&O convert and wouldn't ever consider any other brand for AV products. However, last time I was in London I visited Selfridges, where the Loewe. Gallerie and Bang & Olufsen section are back to back.
First of all the Loewe was much better presented, with a better layout - It was cleaner and had a (imo) better salesman - who was ex B&O incidentally.
At the B&O stand, I was shocked to see that some images were displayed on the TVs through analogue terrestrial with a terrible picture. In general, it was a little shoddy.
Anyway going back to my original point... The Loewe Reference 50". I was going to post in the BV10 thread about this earlier actually. It is similar in style to the BV10 without doubt. I don't know how well informed the above posters are regarding build quality. All I will say is this - In my time, I have taken apart various Beovision 7s, and more to the point, £16,000 Beovision 9s and I guarantee the Loewe Reference is no worse than those two.
I had a demo of it and I personally think it is an amazing TV for the money when compared to say, the Bv9. Loewe is not B&O, we know this, but the fact is, the capabilities of this TV are hands down better than any B&O equivalent currently on the market. And what else does Loewe have? Excellent, logical and technically current link system, 2-Way communication via a very smart remote control with an OLED display which gives feedback of everything. Also a music server (ok not quite as pretty as the BS5) but it does have an integrated iPod dock AND optical drive. Not to mention integrated 500gb hard drives in most of the televisions as well as built in web-browsers and wifi/ethernet/powerline networking capabilities.
In short, Loewe are ahead of the game. And excellent value. When my Avant blows up I hate to say it but I am seriously considering a Loewe Individual to replace it with.
