In Reply to: RE: Tightening HDMI Connection with Teflon Tape = Improved Audio/ Video Quality posted by Dryginger2 on November 23, 2014 at 12:05:15
Tried and like results.Contrast increases as does color saturation. THe change in contrast adds to visual definition, particularly in shadow details. Oh yeah audio is more distinct also.
GOod results for cheap.
INcidentally the spring loaded fingers of HDMI cables are similar to those on volume controls. GOod call.

Uncle Stu,
Thank you for posting your findings.
Using Teflon tape to plug all the empty sockets of the TV set, Comcast box and DVD player and completing a thorough system degaussing (circuits off at breaker box, all cables disconnected and multiple Walker Talisman exposure of AC wall OUTLETS/ cable ENDS/ speaker TERMINALS + DRIVERS) significantly enhances those improvements in my experience.

tried it elsewhere, but didn't mention it. USB cables benefit a lot too.
didn't want you feel the wolves circling. Been there went, through all that.
started with teflon tape wrapping IEC ends (female side) so that it fits more snugly in to the male sockets, works well there,
Uncle Stu,
I agree about IEC connectors but found Teflon tape too sound-damping for use with USB connectors that fared better with rubber o-rings to my ear.
Found that Teflon tape around the fuse holders and fuse of the CD/DVD player makes a substantial improvement and around the fixed wire connecting either end of the large fuse to one of the Samsung widescreen TV's circuit boards a lesser but noticeable enhancement. The rock-steady, eye-popping detail and saturated color of the series 'Rome' after all this is exceptional and even cable TV finally borders on impressive...the sound quality corresponds.
Consider the substitution of brass/ nylon for ferrous/ stainless steel screws to be the critical gateway through the distortion layer that otherwise blocks hearing more deeply into the music so placing other sound improvements beyond audible reach. My continuing thanks for your help in showing the non-magnetic way through...

unclestu and Dryginger2,
Isn't stainless steel a Non-Ferrous Metal?

ipdtt,
Initially I forgot the wisdom of my original mentors and accepted conventional wisdom that stainless steel screws were all non-magnetic. Then one day for some reason I checked one and then each subsequent stainless steel machine screw against a magnet to find that 90% were strongly attracted. So immediately substituted mainly nylon and occasionally brass non-magnetic screws in their place on each component. In the deadening grip of wide-spread EMI distortion, the vitality of the music was throttled, slow, heavy and artificial. Afterwards the sonic flames snapped, crackled, jumped around all around the sound-stage fireplace with ethereal lightness and pace.
Some component machine screws are too small to be stocked by local hardware stores and all mine were metric that they do not carry anyway. However McMaster Carr are the answer for those who check with a magnet that they have a majority of magnetic stainless steel machine screws on their amplifier just for starters.

Stainless steel can be both magnetic and non-magnetic depending on type
according to Wikipedia: http://en.wikipedia.org/wiki/Stainless_steel#Electricity_and_magnetism
Ferritic and martensitic stainless steels are magnetic. Austenitic stainless steels are non-magnetic.
***MAGNETIC***
FERRITIC stainless steel consists of iron-chromium alloys with body-centered cubic crystal structures
MARTENSITIC stainless steels, such as types 403, 410, 410NiMo and 420, are similar in composition to the ferrite group, but contain a balance of C and Ni vs. Cr and Mo.
***NON-MAGNETIC***
AUSTENITIC stainless steels are the most weldable of the stainlesses and can be divided rather loosely into three groups: common chromium-nickel (300 series), manganese-chromium-nickel-nitrogen (200 series) and specialty alloys. Austenitic is the most popular stainless steel group and is used for numerous industrial and consumer applications,

Dryginger2,
Thank you much... That is spot on!
