Description :
The Sim Audio Moon W-3 employs the "Advanced Renaissance" technology featuring a "no overall feedback" circuit and bipolar output devices. It produces a warm, grain free sound common to some of the very best tube amplifiers and has the reliability of solid state designs. With a "no overall feedback" design, it results in real-time amplification - a more accurate musical reproduction with respect to tonality, virtually non-existent intermodulation distortion and the elimination of common phase errors. They also feature a custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor, resulting in increased current speed and better dynamics. It has a high damping factor which yields superior musical dynamics, improved signal speed and refined timbre accuracy. A very short signal path for a faster transient response. When tested and played on, the Moon W-3 is very neutral sounding. The great thing is that it reveals the characteristics of your other associated hifi equipment. The owner will be able to tel what the other hifi charactistics are like and make adjustments. Despite being abit lean sounding, the Moon W-3 is perfectly balanced. It is also very clean, with no hint of grain or stridency. There are no disturbing fluctuations from flat frequency response. The W-3 presents images very precisely. Vocalists have sharply defined lines around their body and an uncanny presence of space between themselves and surrounding instruments. The elements of each recording are very clearly defined and separated. Yet, it isn't very successful at creating air and space. Also, the W-3 does not reproduce the last degree of depth and openness. However, unless you want to go for the more expensive, powerful and higher end model W-5, the W-3 posesses the same sonic signature at a more affordable price.
