Hi, Vishal ... not sure, but I'd think the halogen would introduce line noise ... I love the simplicity of your system, and especially the speakers, ... keep it this way so you can concentrate on the joy of music ... although I agree that you might want to try appropriate tube amplification ... you'll find yourself amazed by how palpable everything becomes
Your Duevels look wonderful and if they sound as good as they look, then you should be very pleased. I'd suspect that you had owned directional speakers before the Duevels, so what is your reaction to these omni's? The listening experience is different, for in my personal experience the speakers will simply disappear as point sources ... it was amazing, for it didn't matter where I stood or sat in the room ... the music simply full and everywhere, and it just didn't matter where I positioned myself. I wasn't ready for that.
