The Pro-Ject Debut PRO B is a high-end turntable designed for audiophiles, integrating advanced technologies and elegant aesthetics.

Pro-Ject Pick it PRO Balanced

The Pro-Ject Debut PRO B is a high-end turntable crafted for audiophiles, combining advanced technology with a sleek, elegant design. At its core is the premium Pick it PRO Balanced moving magnet cartridge, paired with a MiniXLR connector that makes it True Balanced-ready, enhancing system performance for those looking for a refined listening experience.

This model builds on the classic Debut design with significant improvements. Every component has been re-engineered to offer superior performance, incorporating extensive research and development to achieve Pro-Ject's desired sound quality.

8,6‘‘ Carbon-Aluminium Tonearm

The turntable features an 8.6" tonearm constructed from carbon fibre and aluminium, providing both lightweight rigidity and resistance to external interference. The one-piece tonearm design allows for precise adjustments in azimuth and vertical tracking angle (VTA), allowing users to fine-tune for an optimal listening experience.

Speed Precision

Additional highlights include a precise AC drive motor with TPE-damped mounting points for reduced vibrations and stable speed, supporting 33 and 45 RPM speeds and an easy adjustment for 78 RPM. The True Balanced Connection system, developed with Ortofon, minimises noise, enhancing audio clarity, while the precision MDF plinth, dust cover, and height-adjustable feet ensure stability and performance.

Simlpicity

The Pro-Ject Phono Box S3 B is a compact, affordable phono stage designed for both moving magnet and moving coil cartridges, featuring a dual-mono layout, discrete circuitry, and balanced inputs and outputs. With a minimalist, spacious design, it is easily customisable to accommodate a wide range of cartridges, providing excellent value and performance for analogue hi-fi systems. This phono stage’s adaptable structure makes it a standout choice for audiophiles seeking affordability without compromising on quality.

Enhanced Sound Through Discrete Circuitry

In designing the Phono Box S3 B, Pro-Ject opted for fully symmetrical and discrete circuitry in the gain stage, which avoids using operational amplifiers (op-amps). This approach creates a sound that is more neutral, natural, and dynamic, resulting in an authentic high-end listening experience. Although more complex to assemble and involving a wider variety of components, the discrete circuitry achieves a richly dynamic sound profile that appeals to audiophiles seeking clarity and vividness in their audio.

Flexible Cartridge Compatibility

The Phono Box S3 B is extensively customisable to suit moving magnet or moving coil cartridges, with settings for five impedance, four capacitance, and four gain options. This range of adjustments allows it to accommodate nearly any cartridge on the market, making it a highly versatile component in any analogue system. The unit’s adaptability ensures that audiophiles can optimise their setup for the best possible audio output, tailored to their preferred cartridges.

True Balanced Connections and Superior Build Quality

Equipped with balanced inputs and outputs, the Phono Box S3 B aligns with Pro-Ject’s True Balanced Connections concept, which, when paired with a balanced turntable and connection cables, significantly enhances dynamics, reduces noise, and improves signal-to-noise ratios. The steel chassis with aluminium panels provides strong electrical isolation, while the minimalist design allows for easy access to controls. An external power adapter reduces interference, ensuring the sensitive internal components remain unaffected, further solidifying its position as an outstanding choice for audiophiles at this price point.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

James F.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

Guy H.

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

Kaylay L.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
