I am one of your customers and sorry but I can't confirm that. When accurately level matched and blind tested it sounds fine, but not fundamentally better than a good DS dac.
Unfortunately there is no real evidence to justify your words there.
You cannot infirm that too.
It sounds just fine to you doesn't mean much. Maybe to others it will sound more to their taste.
Also having different technologies and designs in dac is good.
I wouldn't like all designs to be the same.
It's not marketing to make r2r dac i think it's courageous to design these dac that measure a little worse that modern dacs.
Even if ds were proven to be the best (to me it's quite not proven) it's good to keep different designs and to have people who want to try new designs.
Having all dacs designed with classic Delta sigma and aop output stage would be very boring.
5 years ago chinese dac were a lot cheaper.
I think now that new chips have extravagant specs designers want to use it and sell it at higher cost.
They design in order to have good specs.
They don't care about the sound or musicality.
So again it's good to have designers who care of the ear feeling and who want to try other designs.
They have the right to choose less good specs while trying to find more musicality.
And if people ear this you must respect it.
