Ideally the loudspeaker would be among the first components selected when assembling a play-
back system. This would allow the user to choose an amplifier capable of delivering adequate 
amounts of current into the frequency dependent load presented by the loudspeaker. However, 
when upgrading a system, audiophiles may find themselves matching their new loudspeakers to 
their existing amplification. For this reason, extensive measures have been taken to ensure that 
each Legacy speaker system represents a smooth, non-reactive load to virtually any amplifier.  
 
Often there is much confusion regarding amplification and loudness levels. It should be under-
stood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound 
pressure level. The amplifier should be able to CONTROL the loudspeakers across the entire mu-
sic spectrum. This means that parameters such as damping factor (values greater than 60 are 
acceptable) and dynamic headroom should not be overlooked when comparing amplifiers.
