I see you use the Mytek 192-DSD DAC, does it work well for you and do you see a reason to upgrade to something else soon? I'm having trouble deciding exactly what I want, with the Zodiac Platinum DAC that I've tested recently, it was a rather nice sounding DAC, quite spacious and a lot of resolution while sounding warm yet analytical (the HD700 that I have shows more pronounced sibilance while not being over the top) and the LCD-3 are amazing on proper masterings, on DSD I couldn't tell exactly what I'm hearing because right now I'm listening to DSD recordings via foobar2000 plugin which converts it back to PCM for processing and it works quite well.
But the question remains - what will be the biggest improvement right, should I opt for that end game amp or should I go for a better DAC first (Which is a problem because some don't have headphone amps in them, like the Auralic Vega which I hear great things about it) and only then get an amp.
i will not upgrade my mytek. its a fantastic dac and very revealing.
the Mytek is not analytical but isn't warm, its very neutral.
theres no clear answer for amp vs dac first but the GSX MK2 is definitely a very revealing amp and some say it even takes the sound of your source. your source better be top level if you get it.
