I’m pretty new to the stereo separates side of audio, so I apologize if this is an exceedingly easy question to answer.
I currently run my DirectStream Junior with single ended RCA interconnects and the 20db attenuator “in/on” to a pair of M700s. My speakers are extremely sensitive, (101db/watt), so even with this setup I can still hear white noise from the speakers at my 13ft away listening position. The noise is not overly loud or distracting but it is noticeable. If I swap the RCA’s for a pair of XLR’s the 6db of extra gain makes the background noise unacceptable, even with the attenuator in-line.
If I understand how all this works correctly I think I can lower my overall signal to noise ratio by inserting a preamplifier like the SGCD into the chain is that correct? If I run the DSJ DAC at 100 volume with the attenuator in-line then I’m maximizing the S/N of that component. In my current setup the DSJ@100 (attenuator in) is louder than I’ll likely ever want to listen, 70 is jamming out pretty loud.
Since the SGCD is line level at volume 76 I would be hearing equal volumes with these two scenarios correct? DSJ@100 = DSJ@100 + SGCD@76
So therefore if I insert the SGCD into the signal path and run it at any volume between 0 and 76 I should be decreasing the amount of white noise that ends up in the music since it will be scaling down a maximized S/N signal correct? Or does it not work as cleanly as that because the SGCD inserts its own noise into the system?
