In the OP your friend had $4k to $6k to spend. Now it changes to "excluding cost" which is fine. Either way, even at the original $4 to 6k if what he wants is sound quality this is easy.
Buy the Decware ZP3, fabulous phono stage for $1300. Buy something like a Benz Glider with .7mV output so you don't need the SUT. This brings him to about $2k.
At this point he has a cart and phono stage that will make just about any turntable sound great. All he needs is a table with arm and built-in phono lead. To avoid having to spend money on a phono interconnect. He can spend the rest of his budget, $2k, $4k or whatever, on a great turntable. All kinds of options there.
And there you go. Done. Not hard at all.
Only problem, it will not be "roughly equivalent." It will be "vastly superior." I hope your friend will be okay with that?
