Sound quality and value/worth is really subjective. Many of us here on these forums have decided that it is worth going upstream. A large number of participants here would say it is diminishing returns.
The units you’re considering are well regarded. However, the only real way for you to know will be to demo/audition in your home with your other components. Ideally, you have a local dealer who will let you try a demo unit (fully broken in). Absent that, perhaps Music Direct or Audio Advisor. I believe both have generous return policies. The downside here is that you’re trying equipment that’s not broken so make sure to give it some time.
Good luck.
