Not likely unless you can hear the 12k artifact (solved with the LPF upgrade
for the DSP).  Which reminds me...someone previously asked whether the LPF
or the full DSP was necessary.  The LPF alone solves the 12k artifact issue
(if your hearing is good enough to hear it) and the full DSP board exchange
adds extended low frequency response...mainly for ESSB.  So it really
depends on your situation.  In all honesty, for my use, I cannot tell any
difference in the 5 different K3s I've had (2 with the factory updated DSP
and 3 without). 

It certainly is a mystery why some experience the mush problem and others do
not.  Luckily I'm in the latter camp but I'm watching with interest.
