RPQ Mic Preamp Review / Sound on Sound
"If you're a fan of ribbon mics — and you have this kind of budget available — the RPQ is a must-buy product. I was astonished at how much better every ribbon I've ever reviewed sounded when it was connected to the TRP preamp as compared to other preamps (whether budget, professional or high-end boutique), and this RPQ version matches that all the way."
RPQ Mic Preamp Review / Tape Op
"The RPQ had so much clean gain that I was easily able to drive a ProTools input into the red ... I moved through all the ribbons one by one, marveling at how quiet the preamp was."
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.
RPQ Preamp & AEA A440 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."
R92 Ribbon Mic Review / Guitar Player
"The R92 recorded an organic balance of room ambience and amp roar. The basic flavor was a fairly accurate reproduction of what your ears hear in the room, but with a fantastic airiness and spatial dimension."
