What does your mac pass the signal to? An external DAC? If using an external DAC, how is your mac connected to the DAC? USB cables do make a difference in sound quality. Cheap usb cables will sound like garbage.
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
