We are very proud to offer the finest quality and most beautiful 24v battery supply on the market today. We ran this Black Lightning power supply at Rocky Mountain Audio Fest in October 2009, and let us say this unequivocally: on high-sensitivity speakers, we highly recommend going "off-the-grid" and if you want to do it in style, the Black Lightning is the hands-down winner.

Like all RWA products, the Black Lightning unit is an extremely refined product. It uses a piezo-electric touch-switch on the front panel and an intelligent SMART board inside that insures that the high-current sealed lead-acid (SLA) batteries inside are not deep cycled. On a single charge, you will be able to run your Virtue ONE, TWO, ONE.2 or Sensation amplifier for more than a full day. Recharge overnight and you're good to go the next day.

Here's a neat twist. Black Lightning has it's own soft-start circuit inside. If you make sure it's OFF when you hook it up to a 2009 ONE/TWO amp, and ONLY turn on the amp from Black Lightning, your switch won't blow up (even if no soft-start module is between the two units). So you can buy this unit today and be running your 2009 ONE/TWO off the grid, tomorrow!

Sonically you will notice the largest improvement on sensitive speakers. The background suddenly goes black, quiet and clear. Bass is slightly fuller and treble slightly more refined. All without expensive power conditioners.

Vinnie says that he can even offer two 24V outputs if you want to power two ONE.2 units simultaneously. Please consult the RWA website for more details.
