Write me via email for a more detailed discussion but despite their size, number of drivers and dynamic range capabilities, all Legacy speakers I've utilized or heard are extremely efficient and do not require large amplifiers. I've know people who use SET, and medium sized/priced tube as well as solid state amplification with very good results. Personally, I have utilized Edge NL 12.1s since 2006 as a matter of personal preference due to their non-colored and very natural sound coupled with vast dynamic range to give the control over the softest as well as most demanding passages. I've also heard Legacy speakers driven by Classe monoblock and stereo amps, CODA and other amp choices and would be glad to share all the good things that I've heard.
Recently, two audiophile friends of mine who have run some sophisticated and expense amplification over the years take a chance on Emotiva's latest top of the line stereo and monoblock offerings with amazing results. They were very surprised and happy with what the new Emotiva offerings brought to the table and at the same time a bit dismayed at how much value and great sound was packed into these amps at a price point that is very accessible. It shattered a number of preconceived notions to be sure. I may be listening to them soon but given they are driving MBLs and other high-end speakers with these new amps, it may be a manufacturer you want to check out to pair with your new Legacys.
Bottom-line, from personal experience, you cannot go wrong with Edge NL amps, Maker Audio (next generation of Edge), Karan, CODA (Reference), Classe CAM-600 monos and others that I've heard.
