That is what I am using but I want to know what the difference would be between the dx300 and say the Holo spring 3kte?
I don’t have holo spring, but I did went through several desktop systems, and currently having TA-ZH1ES, LKS004. Both are modified. However, with all things considered, the main things about DAC is the “Tonal timbres balances”.
Each of them will have different timbres
Each DAC has a different USB interfaces that can effect sound quality, some is more and some is less
Each DAC has it own built and implementations.
But whatever you do, just don’t worry about soundstage or layering etc… they are always packed in that regard, but it depends on how their tonal balances are, they can effect different spectrums and the way the whole picture is portrayed differently
So, IMO, IME, it is all about the tonal balances.
From all of what I know, DAC do not need anything that heavily demanding powerful voltage and supplies. Simply battery packs can and will do better for DAC built, and with all of the DAP recently aiming to be better and better, reaching higher for the sky limits, they have been doing a lot more to the hobby than desktop DAC
Perhaps, in the end, amplifier is where your main considerations will be, as far as desktop system go. Unless you like different technologies and topology, and only want to collect for different signatures, then don’t worry about all of that, just pull your wallet and you get your answers
