UPGRADE PATH FROM CHORD QUTEST

Thank you for your responses. I understand that the best DAC in the world cannot fix a bad recording. But impossible  to know if the lack of detail is from a poor recording or not. Perhaps many of the recordings I listen to are good recordings, but a better DAC that is more musical and better at retrieving detail would make all the difference in the world.  Thank you. 

Sorry if I was not clear in stating the types of music I listen to. Many recordings that I stream sound thin, whether classical, opera, rock, or ballads sung by Sinatra, Diana Krall. etc. For example I streamed Rachmaninovs 2nd Piano concerto using the Qtest DAC and the Lumin U2 mini and the sound was unlistenable. The music itself is as good as it gets.  I was just thinking about getting more detail from my DAC. I like the Chord Qtest Dac, It was a great leap from the DAC I previously listened with. I was just thinking whether I can replace my DAC with the budget that I mentioned and take another leap. Thank you.

I may be replacing my preamp with the Bryston BP-19. Not planning to replace the stock tubes in the Rogue Audio RP-1.  Never said that the Chord Qtest is a problem. I believe that better sound quality can be achieved with a higher quality Dac. So far the Aero Dac has been mentioned. Was looking for advice from fellow music lovers as to their experience with Dacs.  Many members of this site has listened to numerous DACS. As far as cables go I use Cardas Cygnus all around from speaker cables to interconnects.
