1) How can I find my nearest dealer.From Quad's US distributer's web site (http://www.iagamerica.com/quad):
"Phone Quad directly on 781-341-1234 (option 4) to arrange an audition with your nearest stockist."
2) Can anyone tell me what to expect vis a vis my 1.6's (other than price)?You can use them in a second system, give them away to a friend or family member or charity, sell them, whatever you wish. :)
3) Power requirements / efficiency?May be best to discuss with Quad or the dealer.
