Ok, to be back to the original topic, not the update but the low level signal hiss issue, the answer is: it is normal with the DSJ/Huron combination?
I would say no to that, I just updated to Huron again following Teds instructions and the low level intermodulation noise I heard after the
Huron update i did just after release is not there anymore. Now it was just as good as Torreys from this perspective.
Background noise is a tiny bit more pronounced and has a somewhat more - how can I say - “harsh” character in Huron compared to Torreys.
I recorded a 1kHz sine at -60dB (44/16) and played it back (DSj at 100) , and yes there are some audible intermodulation when cranking up the
Hegel to a normal listening level. But I would consider that a rather extreme and mean test, it was just for fun.
I am not surprised and not worried, I know a little about how DS dacs work, so I would say what I heard was normal.
Just to compare - the H360 dac is dead silent in itself and did not reproduce any audible intermodulation with the test tone - still the DSj sounds
so much better. It is not all in the numbers.
After trying Huron according to above I went back to Torreys again, but that is another topic and not related to noise.
