I lived without one for about 20 years and my mint, new, or very clean vinyl sounded great. The reason I bought my VPI was because I buy so much used vinyl now (I find great deals in abundance).
So, now that I have the machine, I use it on EVERYTHING. Let me tell you, I should have done it years ago. It is not just pops and clicks disappearing, it is more dynamic and resolving.
Buy it. You wont regret it. And if not, sewll it on Agon!
