DACs that upsample to DSD internally?

What DAC are you using?
How is it connected to the digital source?
What cables are you using, i.e. interconnect and power.

I stream from my iMac, using a good USB cable, into a musical fidelity USB TO SPDIF converter, into a Bifrost DAC.

It sounds almost as agood as my analogue rig.

I play all formats (except DSD) and sample rates up to 24/192

I would suspect your problem may not be the file format

The one I'm using now is a no name one built from a very inexpensive assembled kit that I bought on here some years ago. I got it for using when I was "in between" DACs. (I would sell one then buy another to upgrade) My last one was a Metrum Octave, but even that didn't have very much detail. I'm not sure which to buy now, but I thought I'd go in the totally opposite direction and try DSD. In any case, my current DAC is by far the weakest link in my system.

My cables do need upgrading also, I have Cullen power cords, a Morrow IC, and usb and digital cords are just from Blue Jean. I recently had dedicated power lines installed. I thought I'd try to find a good DAC before upgrading the cables.

I have the Mytek Manhatten (I).. It converts everything into DSD

Thanks for the response. Do you have any choices? I mean could you listen to PCM if you wanted? If not, can you choose between 64, 128, 256?
