I'm happy to have the Version 4 and HD621, but a version 5 would be nice.

I would like to be able to change the CROSSOVER (Hz) settings from the front panel, on the fly. I'd also like to change otehr attributes quickly without having to do a type change and make a whole bunch of types which makes no sense.

I'm sure there are a lot of improvements and refinements that could be made. I wonder what could be done if they did a new unit from the ground up... A new cost no object processor, what would be done differently. You'd think being software based, it doesn't rely on other peoples 'chips'. they could be updating the software however they want. I don;t know of any other processor that is so software based. I guess all of the digital filters, the crossovers, everything is software based? Whereas other manufactures use 'chip' based solutions...?
