6moons has posted a quasi-review of the Clearaudio Nano phono preamp ($350). This is an entry-level phono preamp with MM/MC, cartridge loading, variable gain, and defeatable rumble filter. Owner/reviewer Frederic Beudot compared it to the phono stages in two integrated amps:
The Nano confirmed that it performs on par or even slightly ahead of the phono boards inside my McIntosh MA2275 and Musical Fidelity A5 integrateds.
On balance, Beudot concludes:
The Nano is warm and dynamic if not ultra detailed and will be a perfect match for many entry-level cartridges that usually shine more with their treble peakiness than tonal precision.
