I currently use the uDSD as a DAC and headphone amp. I do not have an external headphone amp. So the aim of this topic is to figure out if I should get an external headphone amp, and if so, what to get. The alternative is to sell the uDSD and start with a new setup like a Schiit Stack with a new DAC and AMP. The Schiit Stack is just an example, because its neat, compact, fits the budget, and has plenty of power for future headphones as well, but has no DSD support. I believe the uDSD does not get enough power to the AMP part (Hi-Phibian guiding me to try and improve that), but I like the sound and detail the DAC part provides and is much better than my PC sound. I have to turn the uDSD volume up to about 2 - 3PM and then the sound starts to deteriorate fast if my ears are not lying to me. This is now on my X2 headphones, and the sound does not have enough body at any volume, where they sound fuller on other sources without the detail of the uDSD that I like. So maybe a tube amp like the Vali 2 might make it sound fuller, but I am scared of loosing the accuracy and detail of the uDSD DAC. A pair of Samson SR850s does the same thing but becomes unbearable in the highs at that point so I avoid high volume on this pair. The Samson's are excellent for positional sound in FPS games though, and its my use and abuse pair. Not my music listening pair.
Thanks, will drop him a message.
