Yes. The manufacturer will be aware of whether or not the tubes need to be matched and they test for certain tolerances. They generally source hand picked and tested supply whereas an independent is just that-- the quality, credibility and intent to insure top quality can vary wildly depending on who you deal with.
ARC has their reputation and products to protect and service. If you are into tube rolling and esoteric hard to find tube types then roll the dice and see what comes up. If you want to insure consistent tube quality and reliable performance then I would stick with the manufacturer selected and tested lot. They may be a little more expensive because they are tested and matched more thoroughly than most NOS. I used to re-tube my CAT pre-amps through different independents and learned a lesson or two.
