I built DIY Watt/puppy clones. They are nice, and need a lot of power. My Pass Aleph 3 is working hard to achieve medium loudness. I like my symphonies at near concert levels.
I cannot tell you anything about cabling but i am familiar with your speakers and they are incredible! I think you should check on Skiff, that is selling on the Audiogon right now, and you could give me a good (incredible) deal on your Farella's? ;>)
