JM Lab takes the same principles in the basic speaker construction the electra is built using less tecnology. You have read in their lit, Utopias have several devices applied to make it do what it does. First the drivers use better magnets Telar 57. They are more powerful than that of Electra magnets using them speeds up the driver allowing micro movments that bring you the detail and help focus sound stage. They are literaly faster drivers no question. Utopia implies the use of lead in sidewall construction lead adds mass mass effects cabnit vibration, and lead also has very good damping properties. So what differece does that make? Well as a driver is sent its singnal to modulate and reproduce the music you playing, it also modutales the cabinet in wich it rests. The cabinet physically vibrates "modulates" and returns this new vibration although not timely to the driver, remodulating it and adding the vibrations to your music and degrading reproduction. End result, more driver, cabnet, interaction and a less musical speaker with the electra.Still, simmilar sonic signature considering the similarities between the two desigens and materiels used. If you wish to get Utopia pureness in sound but your buget is falling toward Electra I can help you. It just so happens I have some Electras for sale they are modified a bit and I would like to say that in there current form, may give the big brother a run for the money. Plus for 1/3 the cost add a smile to your face each time you listen, knowing you just cheated the system. More info call or E-mail me, by the way I will be listing the Electras hear look for 920s red cherry. Email email@example.com or call 1(780)674-3374 Merry Chrismas @ God Bless! Doc.
