It is only beneficial for Focal to manufacture their own drivers if they can do it to a better quality/value mix than other OEM manufacturers. Given Focal's production volume, this is unlikely to be the case. Therefore if the quality of Focal drivers is truly superior to other OEMs then this is likely to drive up sharply the price of Focal speakers, making them poorer value for money.
Does remote control degrade the sound of tube preamps?
Some preamp manufactures (e.g. CAT) don’t put remote controls in their preamps due to the supposed sound degradation. This could also be just an excuse. Do you think the sound quality is degraded with a remote? I am talking about an audible effect.
