Don’t we all like something new, especially if it has to do with our audio system?  I know I do and apparently , so does Paul’s wife.

The thrill of new

My wife Terri just got a new stereo system installed in our home. It’s the system she’s always wanted, vinyl LP based and personal. I am writing about it today just because I was so in love with her utter joy.

She played album after album last night, well past the point where I had fallen asleep. Moody Blues, Ricky Lee Jones, Miles Davis, Sergio Mendez and Brazil 66.

She wanted to go through the whole process herself, conspiring with our friends at Music Direct who steered her in the direction of a Clear Audio Concept turntable, a pair of KEF LS 50s and, of course, she already knew her amplifier, a Sprout II.

She could hardly finish dinner last night. As soon as my fork shoveled the last bite into my mouth she was all over me to help set it up. What absolute fun we had.

As the needle slowly lowered onto the spinning disc for the first time I watched her grin spread from ear to ear.

There’s little better than the first sounds from a new system. Vinyl or CD, it doesn’t matter.

It’s just the thrill of new that brings a special joy you just don’t get anywhere else.

The difference a few volts make

Most of the world runs at higher voltage levels than we here in North America. 230 volts is somewhat the standard worldwide with the exceptions being Taiwan, Japan, Mexico, and North America (and a few acres of Brazil). Which leaves our group as the odd countries out.

So how does a BHK amplifier, or any product for that matter, sound running at higher voltage?

The same because it really isn’t running at a higher voltage. It just seems like that.

Here’s where people get confused. Our equipment’s circuits always run at identical levels regardless of the source voltage. The power transformers inside our equipment perform what might at first seem like a feat of magic. Without any physical connection between the transformer’s input and its output, one voltage is transformed into another (hence the term transformer). Definitely more than meets the eye.

This miraculous transformation happens magnetically: Invisible force lines of energy. Transformers are little more than coils of wire and hunks of iron: One coil for the input, another for the output. The number of loops within a coil determine its voltage. Thus, the output of a transformer has a fixed number of loops, while the input coil’s loop numbers vary depending on what country it is being used in.

From our stereo circuit’s perspective the voltage feeding it never varies, nor does its performance.
