I dont know about curved tellies
But a wall of curved electrostatics focusing on the 'ideal listening point sofa' will more than blow your eardrums. You'll need to add distortion to make it actually seem loud! I've got a couple of electrostatics and a lot of people complained they produced no bass. A visit to the bathroom at the end of the hall and a couple of inches of water dancing in the bath proves otherwise!
A friend lived in an old maltings and the conical grain drier was the perfect place to hang a 24" fane 400W with baffle and a couple of satellites, the floor covered in wadding was probably about as good as you can get with moving coil. The sunloungers on stilts made great listening seats too! I'd recommend living in a horn loudspeaker if you like some serious rock!
But my idea of HiFi is just that - you should be able to hear the input to the system without any colouration at all. I've still got my els63's after many years and with a good length of mains cable and a decent amp they still outperform anything else - not that I've tried listening to much as I'm normally laughing too hard at the salesmen.
