Leben RS-28CX Preamplifier

The Leben RS-28CX is equipped with the CR type equaliser based on GE(General Electric/USA) 12AT7 authorised by J.A.N.(Joint Army & Navy) standard of US Army, and can reproduce a very high quality and clear sound without adding any NFB.

CR type equalisation requires a high gain level and is much more sensitive to tube quality. Since tube quality will be directly amplified, the finest possible quality tubes are needed for this type of equaliser. Moreover, proper implementation is more difficult. However, the CR type is much more superior sonically to the NFB type, being very stable in the high frequency range and is able to reproduce a very high quality sound especially when high quality tubes are used.
