What is the best tonearm for a SOTA Nova turntable?

Typical speaker is 4 to 16 ohms. Any SS amplifier will have an output impedance <<1 ohm. That’s voltage drive, mainly. Tube amps are inherently voltage producers. That’s why they can have problems with four ohm speakers and particularly with speakers that present an impedance below 4 ohms at mid range frequencies or base frequencies..

Holmz, you could change the predicate of that sentence you quoted to …”constitutes a miniature voltage generator “, and the sentence would be equally correct or incorrect. It’s the impedance at the interface that determines whether you’re in current mode or voltage mode, and apart from the special case of a LOMC cartridge with very low internal resistance driving a current mode phono input with an even lower input impedance, downstream devices drive a high input impedance, in voltage mode.

Holmz, it’s actually voltage based amplification from cartridge to speakers, if you exclude the aforementioned low internal resistance, LOMC cartridges. Although even that’s an oversimplification.

There are many very good tonearms to be had for way less than your quoted cost of the VPI. Possibly even a used Triplanar or Reed. Certainly a used Dynavector, FR, Victor, or Technics, for examples.

Re Mijostyn’s advice on purchasing a current driven phono stage:  (1) That’s a fine idea if you plan to limit yourself to LOMC cartridges with internal resistance preferably less than 12 to 15 ohms, the lower the better, and (2) my own experience with a BMC MMCI ULN Signature phono stage suggests it is superb but not necessarily better than high end voltage driven phono stages with high gain, for listening to the aforementioned LOMC, low internal R cartridges. Not inferior but also not definitively superior.  In a final attempt to be absolutely clear, I don’t hear anything that tells me current drive is going to take over the universe.  But it will assume an important place therein.
