With the technology of today, going from digital tracks to LPs is the equivalent of carving your own granite for perfomance tires, isn't it? Taking a very close and accurate recording and translating it to a mechanical and error prone and wearable media? It doesn't make sense to me. Nostalgia aside, I don't think you gain anything. Someone was just telling me the other day some studios still record on magnetic tape and then take that to digitally master the CD? Again... I must be doing logic backwards.
It would make sense to me to take a current LP inventory and use one of the MP3 conversion turntables to make digital copies to listen to. Storing the albums as an "original and primary backup" so to speak. Easily damaged, high maintenance items, those. For the conservation of the collection that makes sense to me, anyway.
