Flat fee per listing. Percentage fee based on selling price. Find this product on eBay. Completely transparent sound. Like not having a preamp.
Remote buttons stick or something, and no way to control without the remote.
I am very picky about preamps, because they amplify the low-level so many times over they can make or break your sound if they have any coloration at all. I use the DLC in my bedroom system, which is to me my most critical listening environment. The DLC definitely does that. I sometimes run with no preamp, just CD straight to amp. Just switching and really clean, quiet gain.
