Looking For More Detail

Are there other good IC's or are those the best choice for his system?

The key in analog reproduction is the Phono Stage or Phono section in a preamp. Cartridges show differences of course, but from my opinion I could live with a cheap cart. in combination with a top phono but not the other way.
When you want to change the cartridge I think in the overpriced cartridge market the Lyra Helikon closes the gap between superior detail and musicality for a real good price.

I'd look at replacing your interconnects and speaker wires before going to a different arm or cartridge set-up.

I also have a tube preamp and monoblocks. I just purchased a set of Nordost Blue Heaven Rev II on clearance at Music Direct for half off. WOW. Talk about clarity!! They're just out of the box too. I wouldn't have believed it if I wasn't hearing it myself. My interconnects are by Grover Huffman and the turntable leads are stock Nottingham Acespace.

You can borrow cables from the Cable Company lending library to audition in your home with your system. I would go this route if all I wanted to do was "tune" my system.

Carts need frequent adjustment to stay "right". Also a new cart will need even more frequent adjusting as it breaks in.

Headsnappin your point is?
