Thanks for all the suggestions so far. I might be leaning towards phono stage first. Part of the reason is that I don't have a lot of understanding of how much does a turntable matter. In my mind, the cartridge matters more than a turntable in terms of SQ, as long as the TT has reasonably low noise level and tracks well enough. But I can be wrong.
I have heard about Herron. Seems to have some good reviews in this forum. I will give it a serious look. I do like the PS Audio 30 days home trail. Fairly low risk. Thanks!
