If these tweaks are additive as Millercarbon pointed out in another thread, this could be a fun ride..
You have no idea. Most of those who try tweaks at all will do one or two say that's nice and then they are done and go back to running the component upgrade treadmill. I call it a treadmill because you do a lot of work but don't really go anywhere. Because ultimately all it does is get you by until the next component upgrade. A set of BDR Cones however, HFT, ECT, acoustic panel, AC line or outlet, whatever tweak you care to name, is forever. Elevates your game from now on. Actually gets you somewhere.
Any one individual tweak on its own may not seem like all that much. Do enough though and at some point it begins to dawn on you there is no way any amount of money spent on any components ever made will ever be enough.
I'm not the only one saying this either.They do all add together and that is why the few of us who have taken it far enough all agree you cannot get here any other way. In other words tweaks are way more cost effective than components.
