PS Audio DirectStream DAC or Aqua Formula xHD


Any of you have auditioned these 2 DACs can you please tell me the differences in sound signature and is the price difference worth it ?
I'm looking for a very good DAC to use with a Melco music server.
The DAC will be used in a speaker system with Thiel CS 3.7 and also a headphone rig with Hifiman Susvara and Kennerton Odin.

@emcdade  thanks for your input, yes i am familiar with R2R as i have auditioned extensively to the full Totaldac Twelve 4 boxes one of the best i've auditioned to date.Also auditioned the Aries Cerat Kassandra 2 Sig wich is also outstanding but way too expensive for me.I'm therefore considering the Totaldac Seven with separate streamer and reclocker or eventually the new Aqua Formula xHD paired with a Melco music server.



I am not familiar with the Aqua DAC

As much as I like R2R Ladder Multibit dacs, I just read the review and bench tests of the  Aqua Formula dac,, and it seems to have a few issues, especially in the bass, that similar discrete R2R dacs don't have and usually shine.

If you buy an Aqua and dislike it, you're stuck with the sound because it's never gonna' change. 

On the other hand, a DirectStream changes based on the firmware you choose to install. Also, the manufacturer, PS Audio, is committed to evolving the product via continuous firmware improvement. I love my DirectStream DAC.
