For what it's worth, I dropped by Magnolia and auditioned 804D3s against SF Olympica iiis. On their own I'd have jumped at the chance to own either if I had thousands to burn, but next to each other, they unfortunately highlighted each other's shortcomings.
The 804D3s couldn't render the timbre of piano and voice (particularly female voice) nearly as well as the Olympicas. On the other hand, the Olympicas didn't have the instrument separation and speed of the 804D3s. For some music this didn't matter, but for soul and brass band the Olympicas couldn't satisfy. I didn't listen to any electronica, but suspect it would have been similar.
