Sonic Frontier Line One with Class D Amp?

Robbie, 300Ohms into a 40KOhms load should be no problem at all. Shipping from US to Canada is as far as I know, completely seemless. Shipper will just need to remember to declare the unit as manyufactured in the USA (which is actually correct). . . to avoid spurious Customs duty. You should drop a line to the seller and ask if he would ship to Canada. . . worse case is that he will decline. Guido

The damping factor of 102 appears to be 1000, which should enable it to drive speakers with fluctuating impedance curves without issues does it do 2 ohms?

Coffeey, let me know which speakers you have in mind, and their impedance/power handling characteristics. I will try to find out if the 102 can handle them. G.

Hi Robbie.

I have a concern that neither the Bel Canto nor the JR 102 has enough power to drive your speakers at their full potential.

The 802s are 8 ohm and have a sensitivity rating of only 85dB. The manufacturer recommended MINIMUM power rating is 100W w/ no upper limit on wattage. I think you might need at least 200 wpc into 8 ohms for your speakers.

My Dali Ikon 6 are rated at 150w max @ 8ohms with 90dB and I needed a 200wpc amp to get them moving. They could easily take 300wpc.

BTW, I used to own the SF Line 1 with the humongous SF 110w x 2 tube amp. You have a really fine preamp there.

I sspect Mike is correct. With an 85dB efficiency, the speakers will require fairly heft amps with perhaps 35Amps or 40Amps of current. Within class D amps, you need to look at devices built around the ICEpower 1000ASP module, which typically yields 500W and 40A. Examples are Bel Canto Ref 1000 and JRDG 501 monos. I believe some Wired4Sound and Seymour amps also use the same module and may be more affordable. By comparison, I have tried Maggies 3.6 that have the same sensitivity as the B&W 802s with the JRDG 201 monos (250W) and the JRDG 501 monos. . . the 201 monos quickly ran out of steam, while the 501s handled the Maggies handsomely. The 102 stereo yields only 100W and 11Amps of current. . . it is unlikely that it will be sufficient for your speakers.
