Sounds ok in our anechoic chamber Sir, must be your living room...
When people join here looking for help with a poor-sounding HiFi, more often than not after all the obvious errors have been discounted, the problem is attributed yet again to poor room-acoustics.
I'm slightly paraphrasing (well, lots, probably), but one contributor recently wrote something along the lines of "don't complain about your hifi sounding shrill, forward or otherwise insubstantial when the same components in a well-treated room like mine will sound fine". Which in other words says, it's not the manufacturer's fault that your listening environment is not worthy, its yours. But I don't agree with that. In my opinion, if a HiFi component only performs well in an acoustically-treated room, it's worthless to all but the lucky few, no matter how perfectly it measures.
Maybe the manufacturers should throw away their measuring gear, dismantle their anechoic chamber and instead listen to their products in some listening environments that are more like the living-rooms where their typical customers will expect their products to perform well. Such nasty environments include small rooms, irregular-shaped rooms, rooms with suspended floors, mixed soft/hard furniture, big windows, and - God forbid - corners.
And if that means their future products sound horrible in a perfectly-treated anechoic chamber but absolutely fantastic in Bob’s new flat, well who gives a wotsit?
