Designed to replace the "passive pot" preamp sections included in many commercial integrated amplifiers, Red Hill Audio Mini-Pre Preamp Modules utilise the finest quality components coupled with a highly optimised signal path & power supply layout for the finest sound quality.
The design is unity stable and runs from a wide variety of supply voltages.
Passive designs are certainly very quiet, and have good detail because there is zero noise generated. However, they can cause impedence matching problems, sometimes causing poor "drive" to the next amplification stage. These issues affect the frequency response causing "thin" or "light" bass performance and seriously restrain the life and dynamics of your music.
