	I am currently using the Hafler 200/101 pair to drive
a pair of Magnepan MGIIB's.  Unmodified this is not a spectacular
combination.  However, Musical Concepts sells modification kits
for the Hafler electronics.  These modifications the replacement
of most of the caps and resistors with high quality types.
(pp,ps caps;1% tolerance resistors).  Many values are altered.
The change these mods make to the Hafler equipment is nothing
sort of amazing.  The sound had a much more alive quality.
Soundstaging and tonal balance is much improved.  The M220C
kit for the Hafler 220 is priced at $175.  
	The combination of these mods on the Hafler electronics
is hard to beat.  
	You should be fairly good with a soldering iron to install
the mods.  If you built the kits yourself, this should be no 
problem.
