Re: [SlimDevices: Audiophiles] Hum and Hiss

2009-04-25 Thread musicexpression

most decently-built solidstate amps usually has no hiss at listening
volume. some better ones even when volume maxxed out exhibit no hiss.

whatever the case hum should never be present at all in any volume.
there are many causes of hum, from the imperfectly-filtered power
supply unit leaking into the amplification stage (nothing much u can do
about it, since it is inherent)

another source of hum is the improper connections of the RCA, due to
oxidation of the terminals or loose connections, creating ground
loops.

determine where the hum is coming from by disconnecting all the RCA
inputs  using shorting RCA plugs. if it is absent, there is a good
chance that the problem does not lie with the amp.

very often it's the psychological feel-good factor when u plug in a
few-grand AC cable into your prized electronics, thinking you are
providing the best for your toys, and your toys will appreciate it has
been inserted with a 24k gold-plated plug. :)

sidetrack a bit, but does anyone ever open up the TP and peek into its
internals and see what sort of components used? silver wiring/solder,
cerafine caps, precision resistors, etc? ;p

thanks for the eye-opening peektures almost 50% of the internals
contains the all-important air :)

since VFDs are inherently noisy devices that potentially enter into the
audio path, why didn't SD look into the newer OLED devices??? 

but looks like the 802.11b/g pci card can be swapped to a draft N
version...
