Speaker Cable Gauge (AWG) Guidelines & Recommendations

Mes haut-parleurs sont vraiment du pour etre changes. J’ai ces hauts-parleurs depuis 1996, alors j’ai passablement etire leur duree vie. J’attendais de changer de maison avant de me lancer, mais il semblerait que ca ne se produira pas dans un delai raisonnable et j’ai deja du changer ma TV et mon "AV receiver" depuis.

Donc tout ca pour dire que je veux me positionner pour savoir ce que je veux et attendre les ventes d’apres les fetes pour acheter exactement ce que j’aurai choisi.

Comment choisir des speakers? Un autre enfer pour les consommateurs 😉 Mais en attendant de pouvoir repondre a la question, je voulais lire sur le filage car je sais qu’on m’offrira des produits "magiques" qui valent 10 fois le prix raisonnable d’un cable tout a fait equivalent et evidemment adequat.

Je suis tombe sur cet article, que j’ai trouve tres instructif.

When is my earliest sunset?

"The exact date of earliest sunset varies with latitude. But the sequence is always the same. For the Northern Hemisphere, earliest sunset in early December, winter solstice, latest sunrise in early January."

Il faut bien lire la phrase… il y a le jour le plus court (solstice d’hiver), le jour du coucher de soleil le plus tot, et le jours du lever de soleil le plus tard.

Pour les explications, RTFA 😉

Why aren’t the earliest sunsets on the shortest day?

The winter solstice is the shortest day. But the earliest sunsets come a couple of weeks before the solstice.

Venus brightest in mid-February for all of 2014

"Many are asking: what is that brilliant object shining in the west after sunset now? It’s the beautiful “evening star,” really the planet Venus."

"Venus is always bright … but it’s particularly noticeable now because it’s at its brightest on December 6, 2013. It is near what astronomers call its greatest illuminated extent or greatest brilliancy."

Surprising Comet ISON

After failing to appear for Sun staring spacecraft at perihelion, its harrowing closest approach to the Sun, sungrazing Comet ISON was presumed lost. But ISON surprised observers yesterday as material still traveling along the comet’s trajectory became visible and even developed an extensive fan-shaped dust tail. Edited and processed to HD format, this video (vimeo, youtube) is composed of frames from the SOHO spacecraft’s coronographs. It follows the comet in view of the wide (blue tint) and narrow (red tint) field cameras in the hours both before and after perihelion passage. In both fields, overwhelming sunlight is blocked by a central occulting disk. A white circle indicates the Sun’s positon and scale. With questions to be answered and the tantalizing possibility that a small cometary nucleus has survived in whole or part, surprising comet ISON will be rising before dawn in planet Earth’s skies in the coming days.
