@chakster When it comes to passive preamps, there is an absolute, they’re laughably bad! Think it through, it’s a simple Ohm’s law. You want low source output impedance (<200R) and high amp input impedance (>10K). So what happens when you put a 10K, 50K, 100K pot in between? Hint, 10K pot will wreak less havoc than 100K pot. And unless the 10K pot is completely open, it will create progressively a bigger impedance mismatch as it’s turned down. It’s a nightmare scenario.
On top of that, even minor capacitance in the pF region in cables, parasitic, etc. will significantly attenuate high frequencies.
And further, the pot will dominate the sound/noise quality. Wiper pots are very noisy.
And your current induced noise will go up drastically. Using this between a phono preamp and amp is beyond dumb.
With a passive preamp, you’re taking a high quality source component and a high quality amp and turning them both to complete garbage.
Universal solution is a competent active preamplifier.
