Hi - very helpful to read through the opinions about the d10s. I need something like this to get PCM signals into my Marantz pm6006 amp (DAC included that's highly rated). I'm thinking either the d10s or perhaps the Douk Audio U2 Pro (
https://www.doukaudio.com/products/...ptical-12s-converter-digital-interface-dsd256, rave comments about it on Head-Fi.org) - anyone have any comparison comments? They don't refer to the Topping over there.
I'm currently running a HRT Music Streamer II+ (2010, £330 originally) from my PC via USB > pm6006 (2018, £470) RCA sockets > KEF iQ5SE. Good Chord company cabling. Previous decent results with NAD C315BEE amp and Hot Audio DAC (handmade in canada, 2015 £160). Not seeing huge jumps in quality as I move to more expensive components, all that review well on hifi websites. Comments welcome. Maybe a d10s or Douk will make the difference.
Thanks, Geoff
So thanks for the several replies above, I appreciate you taking the time for someone who's new to the site and not contributed before.
My key motivation is to improve the sound quality of my system of course (even though it's pretty good, an experiment then), whether that's an improved USB DAC (surely possible over a 11 year old model, even if that was good in its day). I figured the amp upgrade (using RCA or digital inputs) should be noticeable over the NAD amp (a What hifi award winner), likewise with my speaker upgrade to newer KEFs. But the DAC maybe the weak link.
Computer soundcard digital out - I originally hoped to use this, obviously the most straightforward approach. However, the Marantz needs a PCM input and my Asus Xonar DSX soundcard only provides DTS, Dolby Digital, or Microsoft WMA Pro (looking at the settings in the driver). So I got silence.
Since the Marantz is so well reviewed I thought I'd use the on-board DAC (I see its quality questioned above, I'm interested in what gave that view), and a U2pro or d10s looked like they'd bridge the format issue and output PCM.
If instead I'm looking for a new DAC (rather than a "digital bridge"), then it becomes a different question, and I'd start looking at the options from Chord Company too, Cambridge Audio, SMSL, etc.
If we put those aside though, would you expect a significant improvement with a d10s (or U2pro) to my 2010 HRT DAC, using their analog output and ignoring the Marantz DAC?
Thanks again.
