Yes, I am a true believer that the 800s are 'that much better' than the 802/801s. Now, that being said, are they worth $5K more? That is completely subjective where much depends on the depth of one's pocketbook, not to mention amps, power coming from the wall, room, ears, and knowledge to hear the difference. I don't claim any of the above to be perfect at my house, but I feel they are worth the extra $5K!
