Tube Phono Preamp vs. Regular State Preamp
Most people have a very common debate on whether to go for a tube phono preamp or a solid-state preamp. Because they lack proper information. We will cover the characteristics of both for finding the better one now.
- Smoothness & Warmth
Talking about the smoothness & warmth, there is no denying that the tube preamp is definitely the better choice to make.
There is a subtle & smoother distortion added to the sound by the driving tubes for making things pleasing.
- High-Gain Guitar Amps
The second thing to check between the two is the performance at the high-gain guitar amps. The tube preamps develop a lush distortion that is considered perfect due to the way tubes work.
On the other hand, a regular tube preamp develops odd harmonics and makes the sound transparent. It means one can enjoy higher levels of gains using a tube preamp without any need to reach the distortion.
- Sound Harshness
The performance of both tube & solid-state preamps are different for different instruments. Firstly, a tube preamp works pretty well on almost all equipment types without adding any harshness to the sound.
If we talk about the solid-state preamps, you will likely acknowledge a little bit of harshness while using it for certain musical equipment. It proves tube preamps are a better option to choose for playing a variety of instruments.
Another aspect while choosing between the tube & solid-state preamps is evaluating the price. In this factor, we will say that the regular preamp wins the price battle.
A solid-state preamp cost is much lower than the tube preamps, making it a slightly difficult choice for low budget musicians.
- Higher Signal Handling
Another notable difference between the tube preamp & solid-state preamp is their performance while handling the high gain signals. Our experts have used both of them and find out that the regular preamps work better for higher gain signals.
The work of tube preamps is considered a little bit underwhelming with the higher gain signals in a variety of ways.
How we have selected the best tube preamps? Buying Guide
Quality tube preamps possess a great sort of characteristics that result in making them better. We know most buyers don’t know much about these things, and that’s why our team has presented all those factors in the buying guide below:
- Frequency Response
The first thing to take care of is the frequency response of the tube preamp you choose. As we all know, the normal hearing limits for humans are between 20 Hz & 20 Khz. However, when it comes to selecting a tube preamp, it should be capable of going more than at least 20 Khaz for the ideal experience. Anything less than this range won’t let you enjoy quality music.
- Output Impedance
The next thing to address very carefully during the selection process is the output impedance. The input of a powered preamp directly depends on its output impedance. It is suggested to go for the ratio of at least 1:10. It would help if you chose a model with an output impedance of 200 Ohms for driving a power amp with the input of 2,000 Ohms.
The third specification to check in a tube preamp is how much gain it can offer. In reality, the power amp can reach its maximum output when a tube preamp supplies adequate gains to the system. The best solution, in this case, is to buy a preamp that can adjust its gain according to the requirement.
Another critical factor to take care of is the tubes used in the preamp. Although there are various tubes available in the market, the most common ones are 12AT7, 12AX7, 12 AU7, and 6SN7 among others. As per our expert advice, the best ones to choose are the 12AT7 and 12AU7 due to their price and solid performance.
For those who don’t know, rectification is a technique for the conversion of AC voltage to DC voltage. This process is performed using the rectifier tubes in the tube preamps. The tube rectifiers used in the preamp should be capable of developing warm sound. The most powerful rectifiers used in the tube preamps are 5U4G, 274B, and 5AR4.
The budget of the tube preamp is also an important factor while selecting one. We all know that it is available in a variety of price ranges, so the buyers are suggested to decide according to their budget and requirements. Overspending than required will result in affecting the pocket badly for sure.
