Confusing is that many japanese manufacturers states compliance 100 Hz instead of 10 Hz. Something with a dynamic compliance of > 20 10 Hz. The 3009 Series II improved has a mass of 6.5g so it's a low mass tonearm that needs a high compliance cartridge. Here is what I've narrowed it down to thus far: Based upon what I've been able to find this version of the 3009 "Improved" is designed for higher compliance and somewhat lighter cartridges than the earlier arms. I'd like to get something that provides more detail as well as more low/high end punch. If you're going to use multiple different MC carts you might be better off with a active phono stage or head amp than a SUT.I currently have a Thorens TD 125 MkII SME 3009 Series II improved turntable with an entry level AT cart. That would be a great load for the Denon, which has an internal impedance of 40 ohms but for the AT33EV, with it's internal impedance of 10 ohms, 100 or 200 ohms would be a better reflected load, so a 1:20 SUT would be ideal - that would boost the output voltage of the cart to 6 mV (20X 0.3) and, with a 47K ohm phono stage, give you a reflected impedance of around 117 ohms. So a 1:10 SUT will step up the signal voltage of the cartridge by 10X but it will step down the impedance of the phono stage to 470 ohms. And the load that the cart "sees" is the load of the phono stage, stepped down or reflected by the SUT. The carts can have very different output voltages and very different internal impedances, requiring very different load impedances. If you're going to use multiple different MC carts you might be better off with a active phono stage or head amp than a SUT.īe forewarned - if you're going to use multiple different MC carts, you may not find one SUT that works well with all of them.
