Why investing in a tube preamp will make a sound decision?

For most people out there, choosing a preamp is highly dependent on their pocket. They look for quality features but also at an affordable price, no matter what product or purchase they wish to make. And the case isn’t any different here.

Pro-ject Tube Box S2 Review

Before framing this Pro-ject tube box s2 review, we did a lot of essential and non-essential research apart from trying out the preamp ourselves. And we found out that it is one of the best entry-level vacuum tube preamps currently available market and also in practical use. What a performer!

So, let’s start digging deeper:

  1. Powerful Circuit Design:

Looking for a totally discrete circuit design? The Pro-ject tube box s2 is at your service. In layman’s terms, this means you do not need to spend on an operational amplifier. As the tube amplifier is sturdy enough to maintain steady functioning. This also suggests you can presume an amplified output without any jitters.

2. Cartridge Suitability:

Besides an impressive circuit system, the pro-ject tube box s2 also offers an MM and MC cartridge compatibility.

If you didn’t know, MM refers to Moving Magnet while MC refers to Moving Coil cartridge. MC has less output as compared to an MM type preamp. And MC preamp needs more boost for this reason.

However, the pro-ject tube box s2 preamp works with both MM and MC type phono stage pretty efficiently.

We tried it with our Rega Planar 2 Turntable, and the results were mind-blowing. You can try with any turntable or phono stage and you will see the difference for yourself.

3. Classic Appearance with Great Built Quality:

We did not find the appearance of this vacuum tube pretty appealing. It apparently feels like the makers put more thinking into the tube preamps functionality rather than its design and appearance.

The built quality of the pro-ject tube box s2 phono stage is quite exceptional though. The preamp feels heavy and rich in terms of performance.

4. Easy to Set Up:

The set-up process did not seem paradoxical. All you have to do is set the two most basic settings. These are

  • Input Impedance:

Check out the specifications and find out the input impedance recommended for your cartridge. Also, check out the pro-ject tube box preamp’s user manual, and set its recommended input impedance. And voila!

  • Gain:

Play your cards right to achieve the perfect setting. The kind of setting will be highly subjective to the kind of cartridge available. If the turntable has an MM cartridge then you have to go for a lower gain setting. But if your turntable has an MC cartridge then you obviously need to go for a higher gain setting. Use volume as an indicator to achieve the perfect setting.

5. Sound Quality:

Nothing beats the great sound quality that the pro-ject tube box s2 more than successfully delivers it. It soothes even the most obsessive audiophile’s soul with its super smooth and impactful performance.

You get to enjoy music that is not only appealing to the ears but also sounds more affluent. And of course, jitter-free.

Final Verdict:

If all you need in your life is sound that has a precious charm and character to it, then go for this marvelous creation without any second thoughts.
