[net.audio] Amplifiers/pre-amplifiers and centipedes

rabbit@homxb.UUCP (P.REED) (10/23/85)

I plan on buying a pre-amplifier and amplifier for under $500 - I don't
know enough to care if they are integrated or not.  Any and all suggestions
will be appreciated.  I have Polk Audio SDA-CRS speakers
and a SONY 520ES compact disk player.  I would also like to understand
some terms that NAD and KENWOOD brochures have thrown at me.  What are the
relationships, if any, between dynamic power as measured by the EIA dynamic
test signal, IHF dynamic power, and IHF dynamic headroom.  Also what is
damping factor (ref. 8 ohms at 50HZ) a measure of and what is the current
theory on the effects of the damping factor.  KENWOOD advertises a damping
factor of 1,000; NAD advertises 50 for their amps.  I would assume that
a factor of 20 between the two should affect sound quality differences
if damping, what ever is being damped, has any sonic effect.
Thank-you in advance.

Until the toad in fun
Said "Pray which leg goes after which?"
Which drove her mind to such a pitch
She lay distracted in a ditch
Considering how to run.
