I find that for and Audiophile; Audirvana is almost perfect out-of-the-box after tailoring to my system; Sound quality is 1st class. I have no major issues.
The only feature that I can not seem to get to work is Year Sorting. Once in an artist group I would like to be able to sort by year descending. I have tried various sorting option but still sorts albums by Title; rather than by year,
Otherwise perfect IMHO.
