Pro-Ject Tube Box S Phono PreAmplifier
The Pro-Ject Tube Box S phono preamp is the Best Tube Preamps. This offers impressive performance, unique operability, and a beautiful design. Not to mention, it’s inexpensive compared to any other phono preamp available on the market.
Tube Box S2 is the first Pro-Ject product to offer a completely discrete circuit design, without OpAmp. It is also the first product to ship with replaceable tubes for optimal system synergy. Accepts MM and MC cartridge inputs with front panel gain settings (adjustable via buttons) of 40, 43, 50, 53, 60 and 63 dB. Five variable input impedance settings are available to suit any MC cartridge, while the 47k ohm input impedance setting is fixed and suitable for high-efficiency MC and MM cartridges.
Activating the subsonic filter (also available via the front panel push button produces less noise in the low frequencies, but also takes a lot of energy out of the music, resulting in an emotionally ‘flat’ sound. Ject lists the filter at 20Hz With a slope of 18dB / octave, however, the “20Hz” part confuses me because the filter doesn’t sound like it starts going down at 20Hz, in fact it seems to go down around 30-35Hz.
The gold standard design of this phono preamp is remarkable. The outer frame has a glossy finish that is versatile for new or old turntable flagship models. The rectifier tube controls, inputs and outputs are firmly established. The operability is extraordinary. It outputs weak signals at high amplification and higher input impedance to make music that sounded great. The vacuum tubes, along with other essential features – the subsonic filter, gain levels, and mono settings – work in sync. Other phono preamps with the lower or equal characteristics of the Pro-Ject Tube Box S phono preamplifier have higher prices. This is the Best Tube Preamp in 2023.

What to look for in a Tube Preamp (Buying Guide)
Sound Quality and Preferences
One of the primary reasons audiophiles choose tube preamps is their distinct sound quality, often described as warm, rich, and euphonic. Consider what type of sound you prefer. Do you enjoy a vintage, nostalgic audio experience, or are you looking for something more modern and crisp? Listening to different tube preamps can help you identify the sound signature that resonates with you.
Compatibility with Your Audio System
Ensure the tube preamp you choose is compatible with your existing audio equipment, such as your power amp, speakers, and other components. Check the input and output impedance levels to guarantee they match well with your system. A preamp with a higher input impedance may pair better with certain devices, reducing the risk of distortion and noise.
Features and Controls
Consider the features that are most important to you. Do you need a preamp with a phono stage for your turntable, or are you looking for one with a remote control for convenience? Look for models that offer volume control, gain settings, and possibly even a tube rectified option for added versatility.
Build Quality and Design
The build quality of a tube preamp can significantly impact its durability and performance. Look for models with high-quality components, such as point-to-point wiring and robust capacitors. Additionally, consider the design and aesthetics of the preamp, especially if it’s going to be a prominent part of your audio setup.
Budget
Tube preamps are available across a wide range of price points, from budget-friendly options to high-end audio marvels. Determine your budget beforehand and explore models within that range. Keep in mind that while more expensive preamps often offer superior sound quality and features, there are many affordable options that still provide excellent performance.
Brand Reputation and Reviews
Research the reputation of the brands you’re considering. Companies like Audio Research, Conrad Johnson, and Don Sachs are well-regarded in the audiophile community for their high-quality tube preamps. Reading user reviews and expert opinions can provide valuable insights into the reliability and performance of different models.
Tube Rolling and Maintenance
Some audiophiles enjoy the process of tube rolling, which involves swapping out the tubes in a preamp to alter its sound characteristics. If this interests you, look for preamps that allow easy access to the tubes. Additionally, consider the maintenance requirements of the preamp, as tubes may need to be replaced over time.
By taking these factors into account, you can make an informed decision and choose a tube preamp that enhances your music listening experience, providing the warmth and clarity that only tube sound can offer.

Frequently Asked Questions
What is a Tube Preamp?
A tube preamp, or vacuum tube preamp to give it its full name, is a device that amplifies a sound signal using vacuum tubes as opposed to a solid-state device like circuitry. The source of the sound is irrelevant; it could be from LPs, microphones, digital sources like CDs or streaming, and more.
The signal is processed by the tube preamp to impart warmth and natural sound, making the audio seem broader, sharper, and more rounded. The high-end frequencies will ring true and undistorted, the mid-range tones will be powerful and dramatic, and the bass will sound cleaner and fuller. This makes vinyl sound especially good, which is why many vinyl aficionados have enthusiastically embraced the development of the tube preamp.
Are tube preamps worth it?
It’s quite difficult to define “good sound” or sound quality. There are people who cannot tell much of a difference between vinyl records and digital recordings for every vinyl fan who waxes lyrical about the differences between the two. This implies that there is no straightforward response to this query. The fact that tube preamps produce a unique type of sound due to the tube’s actual moving parts is unquestionably true. Anything digital, or a solid-state device, does not. The vacuum tube’s internal moving parts are what enable it to produce the distinctive sound that tube preamps are known for.
