RCA to 3.5 mm ??


Hello,
I would like to know your opinions on a particular subject which I know nothing about:
HOW GOOD OR BAD IS THE RCA TO 3.5 mm JACK CONNECTION?
I’m interested in one integrated amp which has no headphone input, and has only analog outputs (RCA and XLR).
I’m also interested in one head-amp/DAC which has no standard analog inputs, only digital ones and 3.5 mm AUX.
If I use a 0.5 m cable to get a signal from integrated amp’s RCA to head-amp’s 3.5 mm port - how close or far would sound quality of such connection be compared to standard RCA-to-RCA?
If I go for such combination, there are some cables, like AudioQuest ("Tower", "Evergreen", "Golden Gate", "Big Sur"...), QED ("Reference Audio J2P"), Oehlbach ("MP3 100"), NorStone ("iRCK 280") and some others, but very few, overall. And the general idea behind them was for the signal to travel FROM 3.5 mm jack TO RCA, not the other way around how I would use it.
I would appreciate your thoughts on this very much. Thank you in advance.

Thank you ultra_fi!

But first I need to know about that type of connection - because if that’s a lousy connection compared to more standard ones, I could try other options. But if there’s nothing wrong in general with RCA-to-3.5mm, then I can go for it and then search for the best cable / adapter.
I've already learned a great deal from your replies. Thank you very much for your effort!
Thank you all, I will go with another option, I don’t want to risk with 3.5mm.

You could help me with that too, if you’re willing. I will need to connect a CD player and a Blu-ray player to integrated amp (with DAC) and to a head-amp (with DAC). They all have plenty of analog RCA, coaxial RCA and optical inputs/outputs, so I need to decide what to use. Which type of connection would you recommend for CD player, and which for audio of Blu-ray?
We’re talking about lenghts of 0.4 to 1 meter.
Thanks.
