Martin Logan Purity , can be run from a line level output or speaker level output, your choice. You can even hook them up straight to your Ipod!!

The Martin Logan Purity is a multi-purpose speaker. They are a one owner used pair of speakers and in excellent condition with no visible or sonic defects. I do not have the boxes so it will be local pickup or if you have some factory boxes available to use, I will ship them in your boxes. The following is taken from the ML website in the Museum section, where you can look into them further. Email me with questions at [email protected]

Purity

--------------------------------------------------------------------------------

The World's First Fully Powered Hybrid Electrostatic Loudspeaker
Purity marks an exciting new direction for electrostatic loudspeaker design. Internally powered with a 200-watt high-resolution switching amplifier, Purity allows an unprecedented level of system connection flexibility. Equipped with a standard RCA line-level input, Purity is able to connect directly to devices such as digital music players, flat screen televisions or even computers. Additional speaker level inputs give Purity the flexibility to work with receivers or other equipment that might not have a line-level pre-amp out option
