I had a Winfeld MC with my prior speakers (still running the same Rogue Apollo tube amps), which didn't wholly gel with that cart -- it resulted in a lean/analytical midrange and a somewhat searing top end. The detail retrieval and bass quality were phenomenal, though. I moved on to various Koetsus (tried a few different kinds, including RSP), all of which were a MUCH better match in that system. I got a lush, gorgeous midrange (lifelike vocals and strings), perfect tonal balance, non-fatiguing highs, still very good detail retrieval, and very low noise floor (without insane setup precision requirements) -- but I have to say I somewhat miss the Winfeld's bass. I was using a Sonic Frontiers Phono 1 (un-modded) at that time, which was a very GOOD match with both Koetsu and Ortofon. I moved to a VAC Ren. III w/ built-in phono for a time, and can confirm that this phono is an EXCELLENT match with Koetsu Platinum carts (never tried it with Ortofon).
Given what you've described, a Koetsu Platinum will be a superb choice. In my experience though, the stone bodies give a little better bass response without sacrificing midrange or tone.
Today I have darker speakers, and have finally tried Ortofon again (Cadenza Bronze), and I'm glad I did -- they are wonderful carts! However, even still, that Bronze is warmer than a Winfeld and I STILL have to dial my Tannoy tweeter crossover down 1.5dB in order for it to not sound overly bright (Koetsus needing no such adjustment). And those vocals will never be as bold and present as with a Koetsu.
