Hey BFF bud, rofl. Yes, good that you are emailing people so they will know. Sounds like the head-fi people are being used as beta-testers, and figured it out for you. Hopefully you will update your instructions to include what "Bear" posted, as you posted something inconclusive and contradictory, and you should fix that post as well. You may be right about no bugs, but frankly I'm not that confident, based on track record, so I think it's a good idea to wait and see. If you're right, and there are no new problems and you correct your instructions, I will let him know it's safe to update. He isn't having many problems as he doesn't use Tidal and doesn't have any DSD files. His main issues are low volume output and the unit getting extremely hot during charging, and I don't think those have been addressed as others haven't had those problems, the units are very inconsistent.
Since you want to get personal, I think my brother trusts my advice, and I his, much more than yours, bud.
