Focusrite ISA One (Editor’s Choice)
ISA One is a segment of Focusrite’s classic lineage of microphone preamps.
This no-compromise preamp is esteemed and craved by engineers across the globe. The ISA module is commissioned by Sir George Martin for usage in AIR studios. There are hundreds of popular recordings made with Focusrite’s ISA range, and this legacy is continuing.
ISA uses the popular Lundahl input transformer and the same circuit that is based on the original ISA110. It has been used in successive Focusrite designs for thirty years. The unique sound character is offered by the input transformer that cannot be mimicked in other ways. In addition, this preamp has a twist that the original does not have, which makes it more versatile. The four selected impedances help you match the microphone to input in many ways.
The preamp is encased in a portable and rugged chassis. To date, ISA One offers the Focusrite microphone preamp at an affordable cost. The selected input impedances suit any microphone. In addition, ISA can feed either external stereo cue mix via two TRS jack inputs on the rear unit or the sum of two inputs to headphones’ output.
ISA One has the best feature of tracking options in a small package. It has instrument level inputs, mic and blends a mic input and instrument input simultaneously. The mix can listen through the headphones. The preamp features an output for amp routing, independent gain control, and independent XLR output on the rear and routing to A-D converter.
The microphone input offers the fantastic impedance matching addition as many mics have different impedance at the preamp, and one does not fit all. It makes you prepared. Select between different levels so to match the mic. You can choose any mic without worry because ISA One fits all.
Pros
- Versatile
- Easy transportation package
- Independent flexible DI channel

Grace Design m101 (Close Runner-Up)
Grace Design m101 is a single-channel mic preamp made to reach musicians, recording engineers, or studios. It employs 0.5% precision metal film resistors. The preamp employs a transformerless circuit that is fully balanced and does not has electrolytic capacitors. The detailed unit is musical and natural and has an internally mounted universal power supply.
The m101 has a ribbon microphone mode that offers added gain needed usually by this microphone type. When pushed, the ribbon switch does three things, the input impedance of the microphone is increased from 8.1kΩ to 20kΩ, the 48 V DC blocking input capacitors are bypassed with gold contact relays that are sealed, Phantom power is locked out for preventing damage to the ribbon microphones.
This is a good choice as a DI box. DI input easily accommodates varieties of high impedance input sources. This preserves the sound flawlessly with detail and clarity.
When you have a great recording setup and a microphone, the quality of the recording is amazingly crystal clear. This preamp is perfect for adding character work, but it does not color the voice. So if you want to color the voice and have a natural voice with lesser charm or strength, this is not for you.
If you want a crystal clear voice, then this preamp can be your best bet. Grace m101 is one of the best preamps you can buy without regret and experience the high-quality audio. This preamp is ideal for demanding performers and engineers to meet the sound demand effortlessly.
Pros
- Fast trans-impedance architecture
- High-performance output amplifier

Golden Age Project Pre-73 MKIII
The Pre-73 MKIII is a vintage-style single-channel microphone preamplifier.
The signal path uses only discrete components like resistors, capacitors, and transistors. The output and input are transformers balanced.
The two transformers are different, and each transformer has its unique function. Before integrated circuits were available, the audio components were made in this way. As a result, the sound is punchy, warm, and musically sweet.
Through the years, the classic characteristics have been heard on numerous recordings. The versatile sound works perfectly in most genres and sound sources. Moreover, the sound essence is available at an affordable cost which makes it adequate for everyone.
The mild price tag with extraordinary performance makes this preamp a popular choice. The preamp has 80dB of gain that allows to easily mic sources with ribbons.
Cracking the main gain stage diffuse the tracks with vintage style tasty coloration. You will get phantom power, flexible I/O, broad gain-range DI, LED output level meter, and switchable impedance in half-rack robust chassis.
The PRE-73 MKIII circuit is the same as the classical 1073 module preamp section. As a result, the sound is punchy, warm, musical, and sweet.
You can hear it on numerous recordings. The versatile sound works perfectly on most sound sources and in different genres.
The fine gain adjustments are possible with the output level control. Moreover, these can overload the main gain stages for added character and bring the signal to an adequate level before the output stage.

FAQs About Preamps for TLM 103 (or Any Other Good Mic)
Do I Need a Preamp for My TLM 103?
Generally, the answer is yes! A preamp is one of the essential items for the studio. A condenser microphone needs 48v phantom power for working, and thus preamp is required. A good preamp is beneficial for any microphone. The audio signal from the microphone is weak, so a preamp transforms into a strong line-level signal.
With microphone preamp, the signal processing is done to prepare it for other equipment and further processing. Usually, the microphone signals are very weak to be transmitted to other units such as multi-track recorders, mixing consoles, and other recording devices with high quality.
We can say that mic preamps are not cent percent transparent, and they can vary the tonal characteristics of mics. But mic preamps are a crucial element when it comes to the recording process. For example, a great preamp generally does not hiss, but its tonal qualities can be beneficial during recording as it enhances the sound.
What’s More Important: Mic or Preamp?
Generally, we are told that buying a good quality microphone is far better than spending a huge amount on a preamp, but this seems logical to an inexperienced engineer because a microphone captures the actual sound waves, and usually, it is considered necessary. On the other hand, the preamp adds only volume, so it does not participate in sound improvement.
However, the answer to the question depends on several factors, and one such is the budget. A microphone is a better option for those who want to spend less. A preamp is a crucial stage of the signal path. A microphone is a more modest investment to improve sound quality than a preamp.
We observed that a good preamp could transform the sound of a bad mic into a good one, and a bad preamp makes a good mic sound bad. Different audio scenarios call for different answers; however, from our point of view, getting a good preamp or a good mic is great, but not both. Our choice will be a perfect preamp.
How to Match Mic Impedance with Preamp?
AC resistance of audio signal voltages is the impedance, and microphone signals are AC voltages. The flow of the audio signal is controlled by impedance. A mic’s signal travels perfectly when the microphone’s output impedance matches the input impedance of the preamp.
For microphone optimization, impedance bridging of a microphone is critical. Load impedance must be ten times higher than the output impedance of a microphone. Some consider that it should be five times higher. In addition, magnitude of load impedance should be higher than the output impedance of a microphone so that the mic signal can efficiently flow from a mic to the preamp.
So, The Best Preamp for TLM 103 Is…
Microphones have tremendous dynamic range, and they produce relatively high or low output levels depending on the recording situation. The primary function of a preamp is to convert the microphone output to line level. Therefore, when looking for the best preamp for Neumann TLM 103, you should consider the one with low noise output.
Our favorite from the list is Focusrite ISA One, as it is versatile and selected impedance suits any microphone. It is the best mic preamp for the Neumann TLM 103 cardioid microphone.
