Sonic Frontier Line One with Class D Amp?

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.

Coffey - It doesn't do 2 ohms. Minimum is 3 ohms.
