State of Art Reference Monaural Amplifier
Basically both the ICEpower 1000ASP and 500ASP have neutral featured and well balanced sound characteristic, and they can reflect the differences of equipment or adjustment change forward of the module. Murano Audio used the famous Sweden product Lundahl input transformer as the first stage of Murano P-1000S plus / P-500S plus further, and this design makes this two amplifiers offer much more lifelike music with further details and dynamic!
On the point of view of circuit designing, adding the Lundahl input transformer forward the modules changed the totally input impedance from 10kHz to 40kHz. It offers a more perfect impedance match between pre-amplifier and Murano P-1000S plus/P-500S plus and makes music sounds better. In addition, the audio signal delivered from pre-amplifier would have much clear sound background and more details since the Lundahl input transformer will reduces the common mode noise.
In a word, Murano P-1000S plus/P-500S plus has quite clear sound, plentiful details, delicate sound quality, elastic bass and power punch. It’s no doubt that Murano P-1000S plus/P-500S plus can offer lifelike music enjoyment for music lovers when them collocated with same high quality source equipments, pre-amplifier and speakers. You would never hear such a great and powerful sound comes from such small pair monaural power amplifiers!
