The PS is really critical… my rule of thumb is spend as much on the PS as you do on the TT
I agree with @ghdprentice. in the importance of a phono stage. AAMOF it is the same rule that Origin Live gives. Even so, I do believe there are also giant killers as well. The problem is that they are very few and they have their limits also. IMO, they only kill giants as large as double the price. That would be $2k in your case which will put you at the starting point of what a good phono preamp will cost. I am not sure there are any $1k giant killers in the phono pre arena. But I haven't looked either.
