DS Audio TB 50 Tube Phono Stage
Hybrid EQ Amplifier with Tube Buffer Output
The TB-50 employs a hybrid architecture in which the amplification circuit, including RIAA equalization, is implemented in solid-state circuitry, while the final output stage passes through a vacuum tube buffer. This combination delivers ideal signal amplification through solid-state design, together with the rich harmonic expression that only vacuum tubes can provide. The TB-50 uses the same ECC82 (12AU7) tubes as our flagship TB-100, bringing the world of DS tube Audio sound to a broader range of music lovers.

Heat Dissipation Duct Design
A dedicated duct structure surrounds the vacuum tubes, drawing fresh air from outside the chassis and efficiently venting the heat generated by the tubes. This thermal management keeps the internal temperature within an optimal range, stabilizing the operating point of the tubes and ensuring consistent sound quality even during extended listening sessions.
Ideal Cartridge Connection via Current Drive & Transmission
For both power delivery to the cartridge and transmission of the music signal, the TB-50 employs a current-drive and current-transmission approach that is inherently less susceptible to the influence of phono cables and contact points. Compared with conventional voltage transmission, this approach minimizes the impact of cable length and connector quality, achieving the ideal cartridge connection that DS Audio has long advocated and drawing out the full potential of the optical cartridge.
Adjustable Tube Illumination
LED illumination positioned beneath each vacuum tube can be adjusted to suit the room or listening mood. A continuously variable control on the rear panel allows precise dimming, combining functional visibility with refined aesthetic presence.

Based on 30 years of amplifier-building expertise, Huei offers MM/MC compatibility and integrates turntables to our amplifiers.
Key Features: Supported cartridges: Moving magnet and moving coil - Inputs: 1x Stereo unbalanced RCA input - Outputs: 1x Stereo unbalanced RCA output - 1x Stereo balanced XLR output.
Our Symphonic phonostage brings advanced features and our proprietary technology to vinyl replay, enabling the easy integration of turntables into any system and yielding exceptional performance from your analogue music collection.
Key Features: Moving Coil Cartridge Only - HF Switch Mode Power Supply - Selectable Gain - Selectable Impedance - Rausch Slope Rumble Filter - Balanced XLR Input - Fully Balanced Circuitry - Unbalanced RCA Input - Balanced XLR Output - Unbalanced RCA Output - Solid Aluminium Chassis.
The DS-E3 is the successor of the DS-E1. It benefits from an important number of upgrades inherent to the third generation of DS Audio products.
“Truly beyond price. The DS-E3 is a revolutionary technology in historic record reproduction.” — Ikuo Tsunoda, Audio Critic
“The DS 003 shows emphatically how trickle-down technology benefits the customer, while maintain a pecking order. As close as it is to the mind-boggling Grand Master, enough differences ensure that the two can co-exist: the DS 003 is the more lively of the two, the Grand Master the more subtle. That said, if you can afford a Grand Master, buy it. If you cannot, the astonishing DS 003 will still blow your mind” — Ken Kessler Hi Fi News
The next generation of the Grand Master.
“The Grand Master is so truly supreme in resolution, transparency, spatial recreation, neutrality and any other parameter I can name that it’s impossible for me not say what I usually try to avoid: ‘This may be the best cartridge I’ve ever heard.’” — Ken Kessler Hi Fi News 2021

New milestones in phono equalizer amplifier that skillfully enhance analog playback.
The role of a phono equalizer amplifier is to accurately and carefully amplify the emotional nuances of the music detected by the phono cartridge from the record and pass it to the next stage amplifier. LUXMAN, celebrating its 100th anniversary in 2025, has developed the E-07, an all-solid-state phono equalizer amplifier that sets a new benchmark in performance and sound quality. This model is designed to further enhance the enjoyment of deep analog vinyl playback.
The Moonriver Audio 505 phono stage meets all the needs of any demanding audiophile who loves vinyl records, both now and in the future. Designed with audiophiles, record collectors and vinyl freaks in mind, it boasts 4 inputs for all your turntables, tone-arms and cartridges. It also supports every possible adjustment on the fly with dedicated knobs and switches to ideally match your MC or MM cartridge.
There are two dedicated phono amplifiers in the Sugden range and both are borne from our passion for vinyl. The Stage Two offers exceptional value for money with facilities to cater for both MM and MC cartridges. The design is a two box system separating the power supply from the amplifier. The phono amplifier has fixed loading for MM and 100 and 470 Ohm selection for MC.
Our design criteria was to produce a product that was as neutral as possible, retaining a faithful and enjoyable analogue sound.
