Some studios use consumer based speakers for mixing, and certainly mastering labs do. Speakers like Yamaha NS10s sounded dreadful to my ears but became a standard used by a lot of studios...how anybody could stand these things remains a mystery to me but I get it. Standardization. JBLs in the 60s and 70s had a frequency map like a smile...all lows and highs...big Altec A7s are simply too big for most consumers so smaller furniture-like versions were made...I had a pair of A7s for many years and loved 'em but not in my house. If a system sounds good to you that's what counts, and wondering if so called "studio monitors" are somehow "special" is easily remedied by buying a pair. They might sound great...or not.
Monitors
Few people choose to use professional monitors and associated equipment for home hi fi. The reasons have been well debated before.
BUT Is it possible that upgrading an audiophile system relentlessly including such things as silver wiring can drive towards the slightly uncomfortable (in the home) monitor sound?
