High end prices have spiralled out of control as we all know, but $4800 for a SUT? These are passive devices with not much technology involved. The choice between copper or silver for the wiring is pretty much the only variable (in price as well as sound). There are plenty of great SUT’s on the used market at much more reasonable prices that are in no way inferior to this Ikeda. As long as you choose one with around 3 ohm as ideal input impedance and around 26-30 dB gain, it will match perfectly with your Ikeda 9. There are plenty of those around. Even the uber Audio Technica AT-1000T (silver wired, 8kg!) can be found for less than half that amount. These devices don’t deteriorate much with age (arguably, the silver wired will only improve), so no risks involved like with buying older cartridges. You can save yourself a lot of money. Or if curious buy several for the same money (or still less) and have fun comparing the results.
Compatibility with the tonearm is a much more complex affair and here the choice for the Ikeda (or older Fidelity Research FR-64/66 series) makes perfect sense. For me, the jury is still out on whether 9", 10" or 12" is preferable. I own two 10" and three 12" arms and I can’t really say there is a length determined sonic benefit either way.
