![]() I recently read a post by Norm Varney of A/V RoomService. Norm stated, "It is all about what you have been exposed to – what you've experienced – that is your reference." I agree. All audio dealers should take a day trip to locate and listen to the most outrageous high-end audio systems. Use the references to judge more modest audio systems. Then create audio systems that offer a sizable percentage of these references. That's how you can deliver more "goose bump" per minute per dollar for your customers than your competition.

Source-Based-Tone-Mapping
(SBTM).
SBTM
allows the video source HDR data
to work (map) with a display's
'Tone Mapping' processor.
The
source queries the display's
capabilities -- its range of
brightness, its color gamut, and
other attributes.
SMTM
combines multiple HDR
components, applies its
algorithms,
and
sends the result to the display
to create a better HDR UltraHDTV
experience.

![]() The
Atlantic reports how low-risk,
safe bet algorithms impede new
music's entrance onto the national
playback clouds.
They
note that new music historically
rises from non-mainstream channels
of distribution. The new
music emerges from the garages,
breweries, hills, deserts, and
fruited plains of America. Risk-avoiding
media algorithms are simply blind
to new sources of human
goose-bumps. The next
musical revolution will arise from
yet unknown low-budget risk-taking
programmers. Select this LINK to The

Micro-LED
TV
![]() Micro-LEDs are
nearly invisible to the naked
eye. Micro-LED TVs, ranging
from 81 inches to a wall-sized 1000
inch TV, promise up to 5000 nits of
brightness, blowing past the
brightest OLED and exceeding LCD
sets. Given an LED can produce
absolute black, Micro-LED will
achieve new levels of contrast
ratio. Select the following
