As far as the AVR-507, yes the blue lights are cool. It will be 150X7,DD/EX, DTS/ES, DPLII, THX Ultra2, Neo, Matrix, dts 96/24. List price at $3998.99. This one will have a stepped volume control, new Motorola 56367 processor, source selector knob on the front panel, new universal remote (which is what the holdup is about), single power supply, no balanced inputs or outputs (the new Ref50 will have these) and high quality WBT binding posts on all channels. The new remote will be a hybrid LCD and hard button design and can control up to 20 components. It will be programmed via B&K software for the PC and thumb control for most functions. This is where the holdup is right now. They are getting the remote just right before they begin shipping. There will be a silver finish as well as the black. Hang in there, it will be my next unit.
