Never understood what the sense is in converting USB to SPDIF when you have a DAC with SPDIF ?!? From one flawed interface to the other and things are supposed to be better then ? Unnecessarily complex, expensive and totally superfluous.

When the dreaded USB is a must better design a asynchronous USB DAC without all that conversions. Firewire would be OK but it is too complex for me and as with all good standards it dies first. It seems nobody uses it anymore. Pity.

You don't need to convert USB to SPDIF (I agree, is a big nonsense). You can can easily connect the I2S signals from an HiFace or from the new Amanero board to the ES9023.

Please explain why I would need a device that converts USB to I2S when DACs exist that have asynchronous USB input ? You see I am hopelessly old fashioned and like things to be simple and effective. Can't help it.

Next thing they ask is to design a DAC that (god forbid) can be operated with an app...

JP... no objections on naming our DAC "Subbu DAC" .

Cheers...

My DIY hobby started too late, my BG's are limited to a few PK's (26 x new 47uf/25v) and std's (16 x K-series, 100uF/50V) that are all soldered to LM3886 boards that never finished and powered up These K-series are virtually new with shorten leads. Maybe time to desolder them off the Chipamp.com boards and repurpose them ......

At this point, I will have to pay big $$ + risk of fakes for the more exotic BG's OR DIY within means (does it sound political!!). Seriously, it is a little hard to justify to pay almost the cost of the rest of the parts of this dac for one cap. But never say never with this hobby

Wow that is a guy that knows how to squeeze his customers. One 47/6.3 NX HiQ for $ 29.95. Boy oh boy. I should have bought more when they were still available but even then the thought was that they were too expensive. I recall the price in 2004 was 4 Euro for a NX 47/6.3..... That price only went up in the next years. My NX will be gone soon but at least I have one Subbu DAC with BG NX.

Good, I will ask the mods to have the threads renamed.

I'm not aware of dac with asynchronous USB input in one chip, while I have a few ES9023 doing nothing. A proto of a modded HiFace + 9023 with +/- supplies dac already exist and works very well.
Anyway, that's DIY!

anyone try Silimic's and Cerafine Elna's here? Not the same I suppose - but why chase the taken girl? (Who is no old and out of production). LOL
