Item: SOLD elsewhere: Manley Labs - The Purist - Valve Preamplifier Location: Melbourne Price: $1250 Item Condition: very good Reason for selling: replaced by an Earle Weston special preamp Payment Method: Pickup - COD with free personal delivery around Melbourne Extra Info: Second model release with the 24K Gold plated facia. Retail $1650 USD in 1994. Designed in the early nineties by David Manley himself. With quite a few interesting features and options. For example, three level system gain setting, 3 sets of outputs, or the balance controls also serve as a form of dynamic tone control via their use of variable negative feedback, which works out as ideal for taking the edge off some modern aggressive mastering. "Manley Laboratories 'The Purist Preamplifier'. Designed by David Manley, the Purist Preamplifier uses the best available parts with the shortest, cleanest, signal path possible. This Preamp has all the vital signal conducting electronics located near the input / output jacks with the controls connected with long shafts. The high-current line circuit employed here is one we have developed and refined over the years in our MANLEY Professional series. Minimalist signal path is accomplished with a few short, wide PC traces and very little wire. The signal wire is six nines pure copper, teflon insulated and well shielded. The signal is direct coupled through the tube stages and is only passed through one capacitor per side -and these are premium MIT foil/film caps . The gain controls are precise conductive plastic pots with the main volume being a custom unit specially imported that has superior electrical and mechanical characteristics. These controls are a large part of why this preamp has such a musical appeal similar to precision passive preamps. While passive preamps are notoriously sensitive to interconnect cables, this preamp will be easier to interface due to its constant low impedance output and high impedance inputs. Finally (but really initially) the power supply is a simple, highly filtered, well engineered design without the reliability problems common in other high voltages supplies."
