Please forgive me my Numptyness but what is in it for me? A house call from your local (if he exists) Dr Meridian at an agreed price must be lower cost than engaging Pickfords. Appologies to many members outside of UK who may not appreciate this reference.
I am only interested in two basic points.
1. Getting the best possible performance from the equipment I have with a clearly available, justified upgrade path to a streaming/storage solution.
2. Protecting the future resale value of my investment to date in the eventuality that I can afford a major hardware upgrade in the future.
So, I kindly ask the experts here for advice on "what is in it for me"
I refrained from posting this for 3 hours but my question has already been answered by RGraham. Thank you for your perception and positive comments in prempting my post.
