Technical points in high-end must be taken with a lot of care. I have not owned the 802 Diamond, but two 801 versions and the old 802 series 3. They had similar head geometries, and sounded very good - the 801's needed muscled solid state amplifiers, but the 802 sounded really excellent with an Audio Research D70 II tube amplifier.
In Europe they really represent great value for money, as the imported US speakers are more expensive.
As an apart I must refer two facts :1. that the most impressive stereo reproduction I have ever listened to was the old B&W Nautilus, using four stereo Krell amplifier with a custom Krell active filter. 2. I will not sell my pair of mint B&W Silver Signature SS25 with slate stands.
And yes Amir, the participation of enthusiastic members in WBF is really needed. But those wanting to read about enthusiastic comments should google for Paul Miller, also known for his devotion for the Devialet.
