preamps – ProLogue Premium 2017

The ProLogue Premium from PrimaLuna is a tube preamp that features new front-end circuitry and power transformers for additional control and good bass response. The preamp does weigh almost 40 pounds, making it a restrictive choice for some home stereo or theater setups.

The ProLogue Premium audio preamp has a decent build quality for the price, which runs below many tube component costs. The inclusion of two 5AR4 rectifier tubes makes the preamplifier unique and allows it to provide imaging to reproduce live-quality sound. The component features RCA jacks and tube sockets, as well as a home-theater bypass that lets you incorporate the preamp into some home theater systems. The preamp isn’t automatically compatible with every surround-sound system, however.

The construction of the ProLogue Premium is heavy duty, though the weight and height of the component may make it difficult to incorporate with existing components. Unlike solid-state preamplifiers, the tube component is not stackable; you can’t place items on top of a tube component, and due to the Premium’s weight, you risk damaging components if you place them underneath.

You can expect a similar build quality in the components in this preamplifier, including relay-based switching for all inputs. The relays open and close as selected, managing loads more appropriately than more basic switches. The result for listeners can be clean sound. The preamp also protects itself against power problems; the unit cuts off if it overheats and resets itself after cool down.

Another benefit of the ProLogue Premium is that it comes with a fully functional remote. The anodized aluminum remote includes source selection and controls for volume, as well as some basic controls for the brand’s Premium CD player. Volume controls feature Blue Velvet motorized control for better tracking that doesn’t alter imaging as you go up or down the scale.

Overall, the ProLogue Premium is a decent tube component that is likely to delight hi-fi and music enthusiasts. General home-theater users are probably not going to fully enjoy the component’s properties, however, and may want to look to solid-state surround options.
