It all depends on the gain of the phono preamp, cartridge output and the input sensitivity of the amp! Since your amp has a volume control you have nothing to lose givin’ it a try!!
phono preamp to power amp
It is probably a dumb question, but I am ignorant, why should I pretend. :)
Long story short, I gave away my integrated and bought a power amp. I am planning to buy a second one and use them as monos. For now (and then) can I plug my phono preamp to the power amp? Or I need a preamp? I googled and the answer was mostly "it depends"
