The only way to go budget high end preamp is a passive

"I like the sound a lot better with a CD player directly into a power amp. Is this nuts? It's clearer and has a lot less compression that way."

Then you need to research light dependent resistor attenuators. These are said to be excellent, but with a few caveats, mainly proper source and load impedance matching is needed. Kits and premade units available. Lightspeed, Lighter note, Warpspeed, Eva, and more.

Also you can throw in a tube or SS buffer, either before or after the LDR, to get the proper impedance match if necessary. Still cheaper than a mega buck audiophile preamp.

No personal experience here with these optocouplers yet, but I am currently working on a project that will use one.
