Musical Fidelity X-Tube Valve Buffer blue aura -Frequency Response 20 - 23The purpose of a 'buffer' is to act as an interface between two items at line level (or between a pre amplifier and a power amplifier), helping remove any limitations from imperfect impedance matching that might exist. So for this reason the Musical Fidelity X Tube Buffer has a very high input impedance and low output impedance. This means it presents a very easy load to the item in front of it, whilst offering a very low output impedance to the item
