Just like in the story of David and Goliath, this little guy won the fight.  Instead of paying for huge retail mark ups, 1/2 inch thick sheet metal, and a gigantic advertising budget, the Grounded Grid gives top notch performance at a price anyone can afford.  

How???  We have a better design.  By utilizing creative and innovative circuitry, a quantum leap in sound quality has been obtained at an extremely low cost.  So what is this "grounded grid" thing?  Its a way of driving a tube that was pioneered many years ago in radio design. Its primary characteristics are very wide bandwidth and low noise.

"So how does it sound?"  The unit is blistering fast.  The response is flat to 300 kHz.  The high speed reveals every subtle nuance of the music.  It doesn't "mask over" and "white wash" the music so that everything sounds the same and puts you to sleep.  The preamp is dead quiet.  Really dead quiet.  No hum, no hiss, nothing. The result is a very musical, natural sound that is the complete absence of coloration.  It's accurate and natural without being the least bit analytical.  Ask someone who owns one.

The power supply and audio circuits are located on two separate circuit boards providing optimal isolation for reduced noise. Three individual power transformers are used to eliminate interference.  The front panel is acid etched for a very handsome, durable appearance. The lid is an attractive brushed stainless steel which will never tarnish.  This is a real high-end package in both design and construction--without the big price.
