My husband is wanting to get into rba's and I'm wondering if you all could give me a little advice. We currently use MVP's, VV 3.0, Zmax v5, and I just got my svd 2.0. I think my svd may be the only one capable of sub ohm...is this correct? Also, I've been looking at the kayfun v4 rta, is this a good rba to start with. I won't be doing the building tho, just my husband. I just want to try it out to see what all the hype is about. He's wanting to get a mech mod, ,nemesis is believe, with an orchid rta. We chose rta's instead of rda's bc we hv toddlers and from what I understand dripping requires having your juice handy all the time...do I hv that correct? So anyway, my main question is would the kayfun I mentioned be a good match with the svd2 for someone just starting the rba's and sub ohms?
