Wojciech Pacula has posted a review of the Norma Audio Electronics
REVO SC-2 preamplifier (~€6000) and PA-150 power amplifier (~€5750) at High Fidelity. His conclusions:
“Norma’s system is a living proof that when designer succeeds in this respect result are astounding. There is no coloration of any sort in the sound which allows recordings to sound as they are intended to. It’s a particularly rich, multi-layer presentation providing us insight into a complex musical structure. Impressive dynamics, transparency and clarity further improve this already astonishing picture.”
