Hey all, I am just starting my S3X build and am leaning toward a 4-ohm setup. I will primarily be using HD650s and ZMF Aeolus (which are also 300 ohm), but I am also planning to run the amp into a pair of 8-ohm Overnight Sensations for near-field desktop listening (maybe 30% of my listening time, max). I’m guessing that the amp will drive the OSs just fine at low volume levels at 4 ohms, but am curious whether any of you have real-world experience that would suggest otherwise. Thanks much!
