Musical Fidelity K550 Supercharger

I am using the superchargers with my Lamm 2.1's and VR-9 speakers. It maintains the tonal qualities of the Lamm but with greater dynamics, better bass definition. The imaging and soundstaging is improved. My only criticism would be slight loss of finess in the extreme treble, but this is being very picky. Overall, it is Lamm on steroids. I love the sound of my Lamms and wondered what they would sound like with more power. The Lamm ML-3's will be $140,000. This was a cheaper alternative for me.They are a definant improvement.All that have heard it agree. Be sure to use the 16-0hm tap.

You may be ok running the supercharger off your 8 ohm tap if that is what the manley has. In the stereophile review JA notes that some amps will develop an "ultrasonic peak" when feeding the supercharger and should use the highest- output transformer tap. My Lamms sound better with the 16-ohm tap than the 8-ohm tap. Hopefully you can audition them first.
