@audiotroy Definitely not my normal listening volume, but experiencing that power, stage and clarity was something else, including fun! It's something I would like to do again, but now fear. A McIntosh dealer emailed me based on my same description I gave you. He wrote,
It seems there was a digital “glitch” in the recording, and it made the amplifier reach Power Guard and do its job. You said that they were only slightly pulsing, so for that particular track, you were at full power plus of the MA-9000. The Power Guard was doing its job (as it should), and protecting your speakers from clipping distortion. I would not be concerned.
Leaves me wondering what a clip sounds like vs something else...
I would love subs, but I'm now stuck looking for the best streaming option, dumping Tidal for something DSD to work with my Mc's internal DAC, possibly upgrading the DAC to the latest version. I need to nail down a source, the best possible source within my current sore budget. I'm also wondering it I should have been a bit more patient and waited for the MA-12000. In short, I'm in it deep.
