When I owned the ZH-270, I used Joule Electra LA100 III, LA150 , Joule OPS1 phono stage and also the CAT SL1-MkIII. All are good combinations, with the Joule a little better than the CAT on phono side. The CAT is very strong in dynamics, but a bit less fleshed out in its portrayal of spacial information and depth of images in particular. Cheers,
