Luxman D03X vs D10X

@regafan thank you.. I did watch Steve's YT video.. It was quite interesting.. 

I‘m also looking for a new DAC for my Luxman 590axii and my Harbeth 7ES3XD. Wanted to go with the D-03x but will go without CD now. Narrowed my choices down to

Denafrips Pontus II

Boarder Patrol SEi

Audiomirror Toubadour III

Which one would you choose?

I have the D10x as well. It’s a very good DAC but It’s USB input is not very good. It is a DAC that really benefits from a reclocker or upscaller. Feeding that DAC directly through USB input does not do it justice in my opinion. While the coaxial sounds better, you cannot stream more than 192kHz sample rate and DSD is not supported. Other than weak USB implementation, D10x sounds as good as some $20K DACs I have heard.

@arize84 thank you for your input.. This feedback really helps. I'd be using the USB input a bunch.. So that's good to know this might not be the right upgrade path. I am still waiting on the C900U to be shipped in June.. 

@rman9 Don't let my comment dissuade you; you just need to add a reclocker to your budget, I use a Chinese one (Singxer Su-6) that is actually very good (reference level good) and you can get it new for $600. Alternatively if you have a high quality streamer with coaxial out, you can just use that with the limitations I mentioned. I recently bought a Chord M Scaller to see how that will work with the Luxman (I will report back on performance after I get it).

Another downside that I forgot to mention is that the Luxman doesn't not support Blu Ray or DVD Audio; something I really didn't care about, but in retrospect wish it has that functionality. There are many great studio and concert albums that were released in bluray/dvd that I can't play on the Luxman but can play on a $200 dvd player.
