    Solenoids are the least reliable form of isolator but also tend to be the cheapest ... and are usually reliable enough for stereo applications. Diode-based isolators are a little more expensive and are highly reliable ... but they entail voltage drop due to the use of the diode ... which affects your ouput. MOSFET-based isolators are spendy but are ultra-reliable and have negligible voltage drop. By 'solid state' I'm assuming that isolator is MOSFET-based.

    Choose your approach based on budget and application requirements; there's no lone right/correct answer. You might ask them what they're using for the isolation before buying...
