But seriously I would go for a parasound product over a Yamaha any day,much warmer,balanced glare and grain free sound then a Yamaha.Yeah you can bet JC designed the Halo with the lowest distortion he could get without negative feedback, then just applied a little to clean it up. This gives big clean sound.
Too much feedback sterilises too much and makes thing lean. Not to mention the Class-A bias, bet the Halo has twice as much as the Yammie.
