Expert 1000 Pro

[NickB]

I have just spotted this in the 1000 Pro specs:

"Compatible with all speakers, from 1Ω to 16Ω."      The drop to 1Ω minimum could be very good news for those with speakers with difficult impedance curves.

As for the class A temps, the Pro has better cooling, is supposedly more efficient and uses less class A %.  So a much higher class A temp is a bit baffling!  I would say that if anyone gets anywhere near a 1000 Pro over the next few weeks, (or an Od'A)  it would be interesting to check the temps.  57° was a bit hot!  By the way, I have asked OAC to double check the numbers, if they had actually said 37° or something I am going to look like a bit of an idiot!

I don't belive too much in producer statements...about total compatibility...

Regarding this 57 degrees...I remeber that Devialet informed us a lot time ago that its gear should worek without any problems till 65... But with DPM on, High volume and low sensitivity speakers this 65 will be reached without any problem...

Devialet's amps dont't have heat sinks like big old Krell units...and we have a lot precise SMD inside...

IMO 1000 should work below 50 with DPM OFF and -10dB to guarantee many years of flawless work..

Did you help in the design?
