Look no further, get a tube buffer. I can honestly vouch 100% for it and I’m not afraid to shill the hell of this setup. It’s inexpensive and will blow your socks off. Well, at least it did for me on my Tygr 300 R cans. I tried going back to no buffer for reference after a couple weeks and my A3 just sounds incomplete without it. Cheap Tube Buffer vs Darkvoice 336SE
