I used a mac book pro for years. I never had noticeable sound problems. I suspect the distortion could be from the DAC or Preamp or one of the interconnects. Try another computer source and see if it sounds better. If so, talk to Apple. If not re-assess your audio chain.
MacBook Pro Playback distortion
Hello everyone. I have a computer / server question. I have an Apple MacBook Pro, 500 GB SSD drive, and 16 gb RAM running under Mojave. The computer is 98 % used for music, and I placed about 500 CD’s on the drive in AIFF format. Did this abt 4 months ago, and life has kept me from really listening , until recently. To my surprise , I have a just awful distortion in the playback when using the computer ?? Low end is actually distorted, and the mids and highs are all off base. I have took the system down, and worked my way back, starting with just the power amp and an old IPOD Classic ( spinning drive model ) driving the amp directly. Re-added each part of the system ( with NO, issues ), until I got back to the Apple Computer. Odd thing is I don’t have the problem when using the computer for on line streaming, just ITunes when playing back the AIFF copies of the CD’s.
I think I have the I Tunes playback set-up correctly, but maybe not.
Ideas welcome
