QSC is one of two overseas suppliers i currently buy from. The other is not on this forum so I won't mention them here. QSC is not problem free and I will wait for 3rd party testing before moving their stock from my quarantine case to the fun rainbow one, but they have been around forever and people I trust like and use them with good effect. Never heard of Amo before this summer, and I prefer to go with a proven company.
