All of the JVC stuff I've had, from the ancient 5010 to the massive 5551, has been very well made. But, the solder joints have tended to be rather close together and just about every SEA section has had abysmal solder on it--all grainy and dull-looking. I don't know if JVC used a special grainy substrate and that's why it looks that way, but I don't think so. That said, JVC has to be one of the most underrated hi-fi brands out there, along with Sherwood. The sound those old JVC's put out is extraordinary (I must have at least four of them, maybe five).
