Has anyone tried one of these yet? The manufacturer that supplies the room EQ proccessing for Denon amps has released a stand-alone unit that goes between a Processor and Power Amp. The Denon version is fairly basic in comparison, but at £2500 you'd expect something a bit more special. I've had a demo of it and I was very surprised at the difference it made. It opens up the soundstage, makes everything sound much clearer and gets rid of any boom on the lower end. I was very sceptical about listening to it, thinking that it would only make a small difference, if any. But once you hear how it improves the sound, it's amazing how bad a system sounds without it.
