Or something else? I currently have an SPB-3 1/4 pounder loaded SX. I don't think I like what their giving me. They are great at what they do but I'm just not digging it. I thought I would like the aggressiveness but I am leaning towards wanting a more of a classic P sound. Would jumping up to Nordstrand NP4s be "polishing a turd" too much for an SX? I have read nothing but great things about them here and I am close to pulling the trigger on a set. The price is going to sting a bit but at least I can sell the 1/4 pounders. Give me a yay or a nay and help me make the choice.
