Phono preamp suggestions

I like Sutherland. The least expensive is $900 new. I don't know about "dramatically" and it can be subjective but it should be significantly better. Should match well with Pass too. Good cables and power cord are important, as always.

I agree with the above; not for under $600.

With that PA and Pre why would you limit yourself to such an inexpensive phono pre?  I mean you have well over $15K at retail in the amp/pre combo.  What TT/arm combo are you using?

Ifi Audio Iphono 2 is actually dam good for $500ish.

There is a PS Audio GCPH on AG now in your price range. Great phono pre amp with lots of flexibility. Not affiliated with seller.
