    Can Using the Preamp Section of an Integrated Amplifier Compete with a Preamp?

    Hi all, I fell upon a Luxman Power Amplifier and didn’t have a preamp so I have been using my Luxman L-410 preamp phono out for temporary use with it. Preamplifiers seem scarce in Vancouver is it essential that I find a good matching preamp for competitive sound quality?
