MC22 uses too much CPU
Awesome Donkey:
What CPU does the MacBook Pro have? Also, have you tried running the benchmark (Help > Benchmark)? If so, what's the benchmark JMark score?
If I remember correctly, playing SACD, especially multichannel SACD is one of the more CPU intensive tasks. But I can't remember if that's when bitstreaming (which *should* be lower) or converting to PCM/higher DSD on-the-fly.

Just to be clear, we're talking about the dancing bars display that appears to the left and right of the song information at the top of the screen. I right clicked and disabled that, then did a few trials. With spectrum analyzer disabled I get:
44.1 Music:
Playing: Less than 4% CPU
Paused: Less than 2% CPU
Stopped: Slightly less than paused, but still between 1 and 2%
1080P Video:
Playing: Just under 40 - 45% CPU
Paused: Less than 3% CPU
Stopped: Less than 2%
That definitely seems to have made a difference. I actually had Spectrum analyzer turned off for a LONG time, but turned it back on as a visual indicator of playback, in the rare instance that my DAC or AMP or whatever wasn't responding. I think I'll just leave it off full time now.
For reference, since Awesome Donkey asked the OP, the JMark on this machine is ~4400 .

That's the spectrum analyzer I meant; looks like it's at least partially the same issue in your case. Sounds like that's not OP's problem, but at least I saved you a few cycles ;D
Zsolt Andrasy:
Spectrum Analyzer is definitively switched off.

The original Brothers In Arms has a much higher dynamic range than the remaster. The remaster was always oddly boring to me until I figured this out. I dug out my older version and now I'm happy with Brothers In Arms Again.
I haven't heard the 20th anniversary edition, and I can only find a reference to an SACD in the loudness database. If the numbers there are correct, the 20th anniversary edition is *horribly* over compressed. It shows, for example, So Far Away with a dynamic range of 8. On the remaster I have the DR is 14. The original CD I have has a DR of 20 for that same track!
I know this is as off topic as it can possibly be. I hope you'll excuse me. That album is like an old girlfriend. I know every detail of it and relish it.
