A preamplifier is typically not required to add any gain to your system when you are using it. It is usually lowering gain from the source you are listening to. The number one complaint from audiophiles about preamp performance is noise. So why is it that so many manufacturers design preamps with 20 to 27dB of gain? And you wonder why there is "hiss", and why tubes go noisy or microphonic? PrimaLuna preamps use SmartGain. With a gain specification of only 12dB, you will find your PrimaLuna preamp is as quiet as a church mouse. If tubes are less than perfect, you may never know it because they are not amplifying as "loud". High efficiency speaker owner's rejoice!
Another exclusive PrimaLuna feature is PerfectMatch, a circuit designed to present a perfect 100K ohm impedance to your source components. This is vitally important especially for tube source components, such as phonostages and DACs to sound their very best.
We chose 12AU7 tubes because there are more factories around the world making great ones today than any other tube, so you can try them and see if you prefer their "color." In addition, because 12AU7's have always been a popular tube, there are tens of thousands of vintage new-old-stock 12AU7's available everywhere from the greatest factories like Telefunken, Mullard, Amperex, Cifte, Siemens, and more. Tons of them. If you haven't "Tube Rolled," it's a gas, and how you get that last 10% of PERFECT tonal balance to YOUR tastes.
