Which makes the biggest difference?


In your opinion which component make the biggest SQ difference in the chain of a digital playback system: the amplifier, the preamp or a DAC?
Or, is it impossible to determine?

When I switched from Ethernet to Fibre Optical streaming...


Than you. i know the local ISP ran Fiber optic cable throughout the city/town where I live but hadn’t thought about it within the house. I didn’t know it was available. Now I do and will check further.
+1, Fiber optical conversion in house big improvement. In fact the whole house network extremely important for streaming.
I see the amplifier as separate from digital, preamp important only because it's volume control may be used in place of dac volume. Match amplifier to speaker, not to dac. I'd say preamp and dac equally important.
In my order of preference: Best is dac to quality active preamp, next dac to integrated with passive volume control or stand alone passive pre, next dac straight to amp, last dac to cheaper active preamp. Colorations introduced by cheaper active preamp is least desirable.
They all make a difference obviously, but the preamp is the hardest thing to get right and to me exerts the biggest influence overall.
@artemus_5 Here is a link to how I got going with Fibre optical streaming. I ended up with 2 Sonore OpticalRendu’s. I bought the second 1 immediately after listening to the fist one. I have 2 DACs. I am also a big ROON user so ROON READY was a must for me.

I did not setup my streaming exactly as described above. I used the following network switch instead. Which has 2 Fibre slots.

A recent lesson I learned the hard way was not to put the ROON Server on a computer connected to the home network via a PowerLine network, put it on the regular Ethernet (in any room). With high res music I was getting drop outs which made my think my speaker drivers had gotten damaged. It was with George Harrison’s 50th ALL THINGS MUST PASS. On the song HEARR ME LORD my drivers would sound distorted during busy home internet traffic times during the passages when he is humming. It only happened on that song and was reproducible the times it happened. Luckily I figured out it was the streaming before I took more drastic measures with the drivers.
