they are minor issues to many - quick dropouts of music in the stereo channels etc there are other similar issues across other discs in the sets - added drum sounds, keyboards mixed differently, enhanced effects, different vocal takes and so forth I think when you're considering re-investing in music you've listened to for many years and/or you crave the best possible versions for critical listening, little errors can go a long way to discouraging the purchase I pulled the trigger on a used Sector Three a while ago and was pleased (that used price reflected the value to me, 'errors' and all) your safest bet in 2019? order from Amazon (and be sure the listing says 'Ships from and sold by Amazon.com') if you get the corrected boxes, you're all set if you get 'old stock' Amazon will refund/replace no questions asked, and you can try again
