Andover Audio introduced the launch of its new SoundBites Collection of audio parts with the SpinStage phono preamp (MSRP $249). Making a sublime type assertion in a bead-blasted, anodized aluminum chassis, the SpinStage has been painstakingly engineered to ship ultra-low noise to help just about any moving-magnet (MM) or moving-coil (MC) cartridge. For the MA-based audio producer it is a welcome boost any residence audio system that should enhance on an present preamp’s inside circuitry.
“We created the SoundBites Collection to provide our prospects a gateway to a part system with a robust ratio of efficiency to cost. The SpinStage delivers the flexibleness and the subtle, nuanced efficiency of high-priced phono levels at a really cheap worth. A wise improve to the rudimentary preamp levels constructed into turntables or receivers, the SpinStage brings out the perfect of what the cartridge can ship. For added worth, the SpinStage will simply be a long-term resolution, at the same time as upgrades are made to the cartridges. And, lastly, its basic styling is timeless,” states Bob Hazelwood, Director of Engineering, Andover Audio.
The SpinStage has two key options not generally present in price range phono preamplifiers. First, by including a separate MC acquire stage with ultra-low-noise discrete transistors in a kind of transconductance topology normally discovered solely in costlier designs, the SpinStage advantages from offering the mandatory acquire with out added noise. Second, the addition of an Auxiliary enter restores the enter utilized by the SpinStage when it’s linked to an amplifier that has only some inputs. For instance, a system that features a CD participant or different system might have the enter utilized by the SpinStage.
Phono-cartridge resistive and capacitive loading optimize the SpinStage’s high-frequency efficiency with any MM cartridge, whereas its ultra-high-precision resistors and capacitors ship RIAA response usually correct inside ±0.2dB. Then, the SpinStage’s selectable subsonic filter reduces the ultra-low-frequency noise of turntable rumble that may trigger extra woofer pumping and waste amplifier energy.
Every channel’s sign path is totally separate from the opposite channels, with no sign crosstalk between channels, and all capacitors have been eradicated from the SpinStage’s direct sign path. Omitting these capacitors solely eliminates their contribution to distortion, whereas the servo circuit prevents unhealthy DC voltage from being handed alongside to different parts. Lastly, the outside of the SpinStage not solely seems to be good, its metallic enclosure and the metallic shielding behind its back and front panels defend the circuitry from electrical interference.
