 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. Here’s a LINK to his article Opportunity in Recession  Entreprenuer.com covers a subject that appears at the outset of every economic downturn I have experienced. The story outlines how a business can survive or expand in a recession. Brutal Evidence It includes: • Tighten operating overhead. • Clean up the balance sheet; reduce debt.

more exciting than
electrical
grounding?
 Well, just about anything. However, a compromised electrical ground can jeopardize video and audio performance; think video "spark-lees" on your UltraHD TV screen and high fidelity harmonic detail lost in a "noisy haze". A compromised ground can also expose your electronics to power surges and brownouts. CEPro offers guidance for high-end audio/video installations that can apply almost any audio/video installation.

All other drones defend or block by intentionally colliding with the opposing team. One player per team navigates the specially-marked Striker drone to score through the other team's goal. The
other players work to
block either the
Striker or the
opposing drones with
full-contact
collisions.

Paper-thin Speaker
 MIT has introduced a paper-thin speaker that is entirely different from a planar speaker such as Magnepan or electrostatic such as the Quad. They did not use stators or magnets. Instead, MIT employed the principle of piezoelectric. The speaker relies on a specially-treated piezoelectric film/membrane of tiny domes. It does not vibrate forward and backward as a whole. Alternating-voltage squeezes/releases the tiny domes. For more information, select this Link to Audioholics.com. Driver-less

Samsung,
What?
What
HiFi reports Samsung has
announced the debut of their
S95B QD-OLED TV. It has
the potential to overtake LG as
the leader in TV technology. Yet
their announcement gives this
QD-OLED TV third billing.
Their 8K QLED LCD TV and LCD
"Frame" are their leads in new
product announcements. Plus it's
hard to find mention of their
cutting-edge QD tech on their
website.
((e))coustics.com
offers a possible explanation.
Samsung
may be using QD-OLED as a
placeholder until the release of
their QNED technology. QD-OLED
uses blue orgainic LEDs to
stimulate red and green quantum
dots. QNED tech replaces
QD-OLED organic LEDs
with brighter longer-life inorganic
LEDs.
Samsung's
QNED should take the lead until
micro-LED arrives.
