A440 & RPQ Review / Resolution Mag
"What you are paying for in the A440 is that 'magic' sound - and a degree of authenticity that's as close as is possible to the original 44 - in a package that delivers the goods in a more modern recording chain. And with the RPQ ribbon pre P48 you get a preamplifier that will do it - and for that matter, any other ribbon microphone - the utmost justice."

A440 Ribbon Mic Review / Sound on Sound
"There are now several active ribbon microphones on the market, but rather fewer that give the A440 serious competition. The obvious contenders are SE Electronics' Rupert Neve-designed RNR1, reviewed last month, and the Royer R122, but although these are both great mics in their own right, the A440 is significantly quieter, putting it in a class of its own when it comes to distant-miking applications...Once you've heard this mic, you'll always aspire to own it.
A440 & RPQ Review / Mix
"It didn't take much effort to fall in love with the AEA A440...The A440 is pricey, but well worth it if you're looking for a unique-sounding niche microphone that can reliably take on more than 130 dB of SPL and deliver plenty of bottom end."
