If you’re an audiophile hobbyist interested in state of the art digital signal processing then try out the free trial and see if you like it. Your experience indicates you are quite capable of reading and digesting the various materials available online starting with the guides referenced by Gianluca. If you run into particular problems then there is a friendly community here to help, but we’re not salesmen or employees.
I purchased my HQP licences through Gianluca and can reccomend him as a reseller. If you decide to purchase a licence PM him for a quote.
