Some proper snowflakes on here, strangely with few posts to their name.
My M400 is an epic DAC though the CoAx and SPIDIF inputs are not as good as those on DAC's containing ESS DAC chips.
Should I be outraged and demand an explanation in person ?
I knew my post count would come up eventually, but I didn't think I'd also be called a "snowflake!" It's a two-for-one day, I guess! Here's a tip: Ad hominem attacks never hold water and post counts are irrelevant. Besides, you're completely misrepresenting the issue. Let me help:
Your DAC is (as far as we know) performing within specs and as advertised. In the case of the M500, SMSL sold something that doesn't perform as advertised. Many of us (me included) bought an M500 largely based on SMSL's claimed specs and its performance as measured by Amir. Now that a performance flaw has been discovered, SMSL should offer its customers a solution that will make the product perform as advertised. However, If they don't offer such a solution, there's really no realistic recourse for the average consumer except to (1) point out the issue in forums such as this, (2) demand that the company acknowledge the issue and eventually announce a plan to correct it, and if neither of those happens, then (3) vote with their wallet.
Since us "snowflakes" have tried #1 and #2 and it's been more than a month with no word from SMSL, it'll soon be time for #3.
I don't think anyone is demanding "an explanation in person," but a simple post by SMSL here would go a long way to assuaging the uncomfortable feeling most M500 owners have about the dwindling likelihood of getting their DACs fixed.
I've mentioned before that I also own an M400 and SP400 and have no issues with either -- but that's beside the point. And something tells me that if you happened to own an M500, you'd be an angry "snowflake" like the rest of us.
It's okay - lesson learned. If SMSL doesn't come around I'll return my M500 and get another Matrix Audio DAC (no connection, just a happy customer). With Matrix it's been my experience that you get personalized troubleshooting help and an attitude that indicates the company is dedicated to its customers.
