Hey guys just joined and was wondering if IDA-8 is stable at 1 ohm as I need to drive Martin Logan motion esl as it dips to 1.6 ohms at 20 kHz. Has anyone also compared it to the NAD 390dd integrated as that one I have heard. Thanks!
That's 1.6 Ohm at 20K. If that were in the bass you should be worried
It will perform just fine. If your budget allows, you might consider the IDA16. I realize that the specs show 20 watts as a minimum, but you will get a lot more dynamics with extra power. I have used both the 8 and 16 when developing speakers - the sound is in the same sonic signature - the difference is in the dynamics. Either way - they will sound really good.
