I did consider these having none in the country to demonstrate was an issue thoYes it's just not good enough. When we part with this sort of cash, support is part of why I am paying a firm. It's also why I stay with Restek. I know their stuff is superbly made through 25 years of ownership. I am not convinced I would get that longevity from many manufacturers. I hope I am wrong because sound quality and build quality is what I look for in equipment.
