David Hadaway established DB Systems in Ridge, New Hampshire in 1975 and has been quietly manufacturing world class home audio equipment ever since. Similar to many manufacturers of audiophile gems, DB Systems has been flying under the radar of mainstream HiFi discourse and has gradually and meticulously developed its line of exceptional designs for a small group of followers. The DB-1 preamplifier was among DB Systems’s first products and was well ahead of the competition at the time of its debut. To this day, the company offers revisions and updates to all their products, and the DB-1 can well hold its own in the audiophile market.

DB’s line of audio products includes preamplifiers, power amplifiers, electronic crossovers, tone controls, phase inverters, and accessories. All products are designed and hand made in the U.S.A. using selected parts. The DB-1 comes with the DB-2 linear power supply and includes the DB-designed MM phono stage, the DB-5 precision tone control and the DB-4 MC head amp. When new, the complete preamplifier setup sells for 2,200 dollars. Used versions of the preamp can be found at very competitive prices.

The DB-1 shown here arrived in very a poor state despite being advertised as ‘in mint condition’. The phono stage was dead on both channels and suffering from multiple contact-related issues. The power supply was also dysfunctional due to a faulty DIY job and fitted additional capacitors that had come loose during transport. After a few weeks of care and attention, we were able to restore the unit’s original design and functionality. The time and effort was well worth it, as there are not many preamplifiers around that can measure up to the DB-1’s performance.

For a transistor preamplifier device, the DB-1 offers a surprisingly homogeneous and ‘analog’ sound. Its sound stage is both wide and deep, and separation of instruments is commendable. The phono stage is among the best in the market with an extremely low noise floor and superb RIA compensation. Paired with the right cartridge, it is detailed, dynamic, and extended.
