10-22-14: AbcaudioI have no directly relevant experience, but I'll mention that the impedance curve of your speakers, as shown in Figure 1 here, will result in their tonal balance and sonic character being particularly sensitive to the output impedance, damping factor, feedback characteristics, and drive capability of the amplifier that is being used, and (especially if cable length is long) to the inductance and resistance of the speaker cables. So my suggestion is simply that you consider responses that may be provided to your question to only have much relevance if they are based on experience with the same or similar M-L speakers.
Thank you all for your replies! I currently use the Rocket 88 tube amp from Cary. Not sure if this is the best choice, but what I have to use. I appreciate your comments here. Also wondering everyone's take on the cables...anyone have experience with TARA Labs or Wireworld?
Enjoy! Regards,
