You have lots of options, are you dead set on a 1 box unit? Both of the Mac's you've listed are very nice, haven't heard the modwright. The Mac's will give you a more linear, cool for tubes, presentation especially the 2300. If that's what your after the 2300 is hard to beat IMO. Stevecham had an interesting suggestion with the PV10 which is excellent for the $$ especially if your interested in a warmer, more liquid midrange type presentation, but not the last word in detail. Your speakers come into play here. You could even get the PV 10AL or whatever model is line stage only and get an outboard phono stage for the same money or less than the Mac's.
It really depends on your listening preference, I have always been a fan of outboard phono stages.
