I started ripping vinyl onto a PC harddisk at least 20 years ago. It was an expensive method then since hard disks storage space came at a high price. About £1 per Megabyte to be exact. Ripping software such as Roxy Easy CD Creator were the bee's knees. Than came Cd burners and that made the whole process a lot cheaper as far as storage space was concerned.
But life has turned full circle and it is back to a hard disk again since they can store a lot more than a CD.
Over the years I have used a regular set of records for testing and I am always on the look out for alternative format releases of those records. One of them is the album from Marvin Gaye called What's Going On. I have used that without fail to determine all sorts of things within a recording and the playback there of through various equipment. I have ripped the album many times and using a variety of arms, carts, turntables, A t D converters, etc. So there is very little that I don't know about that album as far as its quality is concerned.
But then I went a got myself the official digital release in 24/192 (plus a few others). Within the first few seconds of playing that I noticed the better channel separation and depth, plus additional notes from the instruments that I had not heard before.
This has had me thinking over the past few weeks. I concluded that the better separation is down to the fact that the separation on a TT cartridge is nowhere as good as a proper L and R recording in a digital format. As for the audio information: the vinyl cut is dependent on the quality of the cutter and its audio performance. In a direct master analogue tape to digital transfer the vinyl cutter is no longer in the loop and therefore no longer a factor.
I am only just beginning to experiment with vinyl rips versus direct mastering tape A to D audio file. But the results so far are most encouraging.
