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 design of this phono preamp is remarkable. The outer frame has a glossy finish that is versatile for new or old turntables. The controls, inputs and outputs are firmly established. The operability is extraordinary. It outputs weak signals at high amplification, which makes the music wide and amazing. 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.

Little Dot MK II Tube Preamp
- Little Dot MKII greatly increases sound quality, dynamic range, output impedance, and harmonic distortion
- Little Dot MKII also gains the driver tube-rolling options from the rest of the MK-series with the ability to roll 6JI, WE403A/B, GE5654, M8100,...
If you want a preamp that can balance useful features with excellent sound quality, look no further. Truth be told, the Little Dot MK2 tube preamp is undeniably excellent when it comes to sound quality. Additionally, the audio it produces has a clear, round, and spacious nature that many preamps lack.
The Little Dot MK II tube preamp is known for its flexible sound quality by fully affecting smooth impedances and distortions using its tube amp innovation. You can lower the impedance level to 600 ohms from 50k ohms, which can also lower the clamor level. This preamp device prepares for fully controlled additions with the boost switches so you can change the rating to achieve the most extreme level of performance quality.
Also, the Little Dot MK2 has options like conductive tube bearing, capable of hitting EF95, CV4010, M8100, 6JI, etc. in the factory setting of the jumpers. So if you’re new to vinyl, you might be less afraid of messing up while you’re experimenting.
However, the tubes are not of the best possible quality, so you may have a hard time rolling them. So we recommend that you get other tubes to replace if you want to experiment.

The highlights on this Reising A10 EL34 Tube Amplifier are great for bringing the voice quality into the dynamic range. This device is set up to work with high-quality Hi-Fi capacitors. These capacitors connect the channels, reducing turbulence. Therein lies the coupling capacitance innovation, which improves quality. The Netherlands developed Hi-Fi class capacitors, which make the sound more intense, direct, and exceptional. Similarly, aside from the inside features, the exterior appearance is mesmerising, thanks to the use of high-grade aluminium material and CNC manufacturing.
Frequently Asked Questions
What is a Tube Preamp?
Devices and tools have evolved as technology has progressed, and transistors have taken the position of tube amplifiers in this case. However, classical audiophiles argue that ancient tube preamps provide better long-term and cost-effective quality. A tube amplifier, sometimes known as a valve amplifier, uses vacuum tubes to boost the loudness of audio signals.
