So the whole purpose of buying this having already owned quite few of the albums, is the fact they are remastered versions of each album. Comparing the earlier albums obviously showed a large quality jump, most noticeable volume. But as the albums move on through the years they are so subtle in difference that you may not notice a difference. My only real issue with the set is the sleeves the compact discs come in. The artwork looks as though they are scans, the artwork just isn't as crisp as I'd expected for a Sony product. It makes me want to keep my original versions just for the sleeve notes and better quality of print housed in a plastic case. Would have given this 5 stars had the set been in a better box, however for the price I see why they did this. Overall an amazing artist and great to hold the whole of his studio works in one product.
