Dear Bogeybuster49: Yes, the Rosewood Signature Platinum is way better and with lower output too. I don't see any real trouble with the Rosewood in the VPI tonearm, I respect other opinions on SUTs but for me an active high gain phonolinepreamp is the best choice for the RSP or other LOMC cartridges. Yes an external SUT can works but then ( other than the SUT ) the very sensitive cartridge signal has to pass for additional stages: IC cables and connectors that degrade that precious cartridge signal. In the other side and talking on that kind of high quality performance level we have to think that the stand alone phono stage must be a real first rate design.
One of the gentlemans here posted that your Monbrison " is not a good synergy with " but this is a problem of Shindo design and in any way means that other SUT can beats a top well designed active high gain phonolinepreamp. IMHO if other audiophiles think that is the other way around and the SUT is better their way of thinking is telling us that they own or owned the wrong or not very well designed active high gain phonolinepreamp.
Of course and as always it's only an opinion.
Regards and enjoy the music,
