Hi Raul,
Thank you for your detailed feedback. I have followed you and your answers in Audiogon Forums for a long time, which means I have a big respect for your knowledge and experiences. So I am pleased to get your feedback here.
I may think of some other tonearms but decided to have the same tonearms in order to compares cartridges better (same t/t same tonearm less parameters on cartridge comparisons), also I am very used to Graham, its settings. I also considered if a 12 inch might be the second tonearm but then decided to go with 9 inch. I have read in those forums that Graham is best with 9 inch. I may be wrong on that. A second consideration is IC-70 phono cable as Graham suggests that one and I have it with my current Phantom. I never tried another phono cable, rest of my audio chain (with exception of power cords) is all Transparent XL (mm2) so I wonder if Transparent XL phono vs IC-70 makes a greater synergy with rest of cablings.
I listened to Ortofon PW in an Audio Show in London years ago, I used to like what I heard. I will consider that suggestion as well. That being said, have you tried or listened Anna vs PW? I presume they use same stylus (Nude Ortofon Replicant 100 polished) so I guess their trackings should be similar (which I checked now and interestingly PW having 100 vs Anna's 80).
Regarding Phoenix, I found it more musical over Orpheus (I also have Orpheus and spent 4-5 years with that). After I realigned Graham/Phoenix with Feikhert Universal Protractor (PtS distance was harder for exact measurement due to Phantom's spherical top over pivot anyway that is another story), there has been a remarkable improvement (more relaxed but tonally correct and better upper frequency details etc). So my idea to add another tonearm/cartridge is not due to I am not pleased with Phoenix.
Thank you for your feedback for the issues above.
