Thanks for your input Chris. I wish I knew of your existence before purchasing speakers! Only $2k for something comparable to an 802/801D would be an absolute steal. (Do such older hi-quality speakers as these need some sort of refurbishing, ie eletrolytic capacitors, foam surrounds, etc?). Not so hot looking, but I don't care too much for the looks of the current series either, to be honest. However, I don't put too much stock into looks.
I believe the 801 Matrix used primarily plastic film capacitors, which have a longer life then electrolytic examples. Though, some electrolytic units may still be used due to economy of scale(
the Zobel network section of a crossover generally requires very large values -- making an electrolytic the only economically viable option for a production speaker -- but since the 801 was very expensive to begin with -- I just don't know. You can ask B&W technical support, they may be able to tell you for certain if it uses any electrolytic units.). I am not sure if the surrounds are foam -- you should ask B&W.
What do you know about the 804s (no D tweeter), and how they might compare with its superior siblings?
They do not measure as well, and the cabinets are not resonance free, as they are in the 802D/801D/800D. Timbre distortion will result as a consequence of this.
Which EQ's do you recommend?
If you want a high value unit, I recommend the Behringer DEQ2496 or the DCX2496(
which is a much more powerful unit with additional options/features to be used in the future). This is balanced professional equipment, there for you will need to add in the cost of some adapter cables and possibly an balance/unbalance matching adapter, depending on the specific equipment that you need to interface.
What are your most significant (measurable) complaints about hybrid electrostats (which I do own)? (I know they have a very limited sweet-spot, required room from boundaries, must be powered, tough impedances, compression at "reference-level" volumes, etc).
Maybe more questions later! Thank you again
Well, I don't know which unit you own; is there a credible 3rd party measurement set available for this unit that I can review? But, regardless, the off axis response is terrible with the standard type electrostatic panels (exception being some rare systems with special acoustic lenses placed over the panels). This type of speaker, for best sound quality, requires a single listening position, and a room that is extremely well treated acoustically, to prevent the off axis differences from contaminating the overall sound that you hear. The problem is that some room contribution is a positive thing for overall sound quality, according to credible perceptual research by leading psycho-acoustic experts such as Floyd Toole and Sean Olive.
