I don't want to argue with Raul too much, because I do agree that a solid state phono stage has a better chance to be really dead quiet with very low output MCs (let's define that as 0.3mV and below), but it is also possible to get there with tubes and especially with hybrid devices employing both transistors and tubes in the signal path. Typically in the latter case, a transistor is used at the input as voltage amplifier. Apparently the Herron using its MC input is one such device. With MM or MI cartridges, any really good tube phono stage ought to be very quiet; if it's not, there's a problem either with the design or the tubes or with grounding. My vintage Quicksilver full function preamplifier, old as it is, is as quiet as any CDP, when driven either by my Grace Ruby or my Acutex LPM320.
