For many, a microphone pre-amplifier is essential in a recording studio. So you’ve finally grabbed the perfect microphone to begin recording or performing, but still need a specific device to power it up? The best microphone preamps in the market today come with many capabilities aside from merely providing some phantom power to allow your microphone work, and depending on which route you go, can do wonders for your current setup in terms of expansion, upgrading, and standing out from the rest. Today we took the time to review the top 10 best microphone preamps out there worth looking at, however come with a few extra factors when it comes to determining which is best for you.
Picking the Best Microphone Preamp
If audio interfaces aren’t your thing, or perhaps you’d like to step up your recording gear game and grab more control over your recordings, you’ve come to the right place — we need something to not only power up our microphones, but to tweak and shape them as well.
Mic preamps give us way more recording capabilities and flexibility as opposed to many interfaces out there. Before getting into our list of the best microphone preamps, there are definitely some requirements to look into first. Although one of our favorite resources (Musician’s Friend’s preamp buying guide) explains this in a bit more detail, we’ve done our own research from multiple educational sources to give you some insight into the preamp selection process before you pick the best model for you.
- Price-point – This will begin our preamp requirement since money is always first. Since there are so many options out there in the preamp world, the amount of money will steer you in a particular direction (or perhaps encourage you to save up a bit more before buying yours). There are some (and only a few) within the $100 rage, while others can be 2, 3 and even 4 times this amount (most of the professional solutions hit a grand or more).
- How many channels? Aside from price, here’s the most important factor of your decision. The most popular microphone preamps come with either 1-channel (for one microphone at a time), 2, 4, 8 and more. To put it simply, however many mics you plan on using (keep in mind at the same time) with your preamp will need their own channel. Are you performing live with a big band and have a lot of dynamic mics to power up? You’ll need a bunch. Recording in a studio with some condenser microphones and a few instruments at a time? Perhaps 4-channel or even 2-channel may suffice, since recording the different instruments\members can be done separately and not simultaneously.
- Type of preamp – The most popular and best microphone preamp models come in either a tube, solid state or hybrid type. This will largely affect the overall sound of your output. Tubes are known to be harmonious, while solid-state are more “digital-sounding”, crisp and clear. Hybrids on the other hand entail both of these (for quite a bit more money). We tried to include a variety below.
- Ins and outs – Aside inputs and outputs in a mic preamp in terms of count, there are also different types of I\O’s out there (some with hi-Z direct input for a bit more money as opposed to standard). If you’re unsure of the types of I\O and don’t see yourself being concerned with this, just keep in mind how many ins and outs you’ll need (now as well as the future). Are you recording or performing bass, guitar and additional instruments that require something aside from your desired microphone XLR input channels? Keep the count high.
- Extra features? Aside from preamp types, ins and outs as well as channel count, there are some additional features they provide that may or may not be of use to what you foresee yourself needing. Here are some popular features people tend to lean towards: VU meters, large impedance ranges, ADAT output, hi-Z switches, rack-mount compatibility, low and high-pass filters, and more.
The Top 10 Best Microphone Preamps
Here’s our list of the 10 best microphone preamps in the market today. Honestly, it was way too tough deciding on 10, and we could probably create a list of 30-40 if we could. However, we did our best to narrow down our list to cover different channel counts, price-points, and of course, features offered to give a wide array of options to pertain to multiple readers. Keeping it broad also helps you decide which microphone preamp is best, as opposed to just picking “one” in our opinion — that just doesn’t seem right. Keep leaving us some comments with your favorites and we’ll continue to keep them in consideration since we update this guide multiple times a year.
ART Pro MPA II
If you are looking for one the best microphone preamps in the market today, then the MPA II is a very solid model that’s reviewed highly by many. We went with a simple dual-channel tube model to begin our list since it will fit the build for a majority of preamp searchers; however, keep in mind we found it difficult to choose an exact best since (as stated previously) since it really depends on a few needs of yours. To highlight, and although highly affordable (at least compared to other 2-channel tube preamps), there are lots of powerful professional characteristics which will make this mic preamp a positive addition to any studio for projects or mobile recording\performing. It is a 2-channel tube model powered by a 48-volt phantom engine, has big VU meters and impedance with selectable input as well as stereo and dual mono support.
There’s a convenient mid-side mic switch that will enable versatile and flexible usage and with the variable impedance (ranging from 150 to 2400 Ohms) you’ll also be getting a flexible mic sound. Aside from this, there is also a low-cut filter for each channel that will help sort out possible problems with background noise and rumbling. For build, you’re getting a solid chassis here that won’t break on you easily, and this mic preamp also comes with an appealing color LED front-display and lit up switches of functions for easy and practical visibility over the controls. The ART Pro MPA II is an amazing solution for those looking for a 2-channel tube microphone preamp that comes at a pretty affordable price-point that we highly recommend if it fits your checklist.
Focusrite OctoPre MkII
Up second, we begin to delve into the larger channel counts and digitally enhanced microphone preamps in the market today. If you are looking for the best microphone preamp in terms of multiple channels affordability, then the Focusrite OctoPre MkII is definitely one to take into consideration. It comes with 8 pre-amplification channels and inbuilt ADAT output with 24-bit and 96 kHz power for excellent sound quality in different settings (usage in a studio, a live performance, broadcasting, seminars, etc.). This will enable you to get the best out of ADAT inputs, which makes it perfect for a variety of preamp inputs on the interface. You’ll be provided with will provide 20 Hz – 20 kHz (+/- 0.1 dB) frequency response for clean sound and minimal presence of background noise (EIN larger than 125 dB).
The mic gain is in the range of plus 10 dB to plus 55 dB and will provide four channels per individual port (at 88.2 and 96 kHz, which means that you are getting more than enough phantom power for all the preamp needs you have). The build is also fantastic, with easy-to-use rotary knobs on the front that won’t breaking anytime soon. The Focusrite OctoPre MkII is awesome not only because Focusrite is a brand we can trust, but the quality of this is unmatched, especially if you’re in need of 8-channels.

Up next, we have one of the best microphone preamps out there right now that’s great for those in need of only one mic channel but are very concerned with power and sound quality. It comes with a trans-impedance topology of circuits that is at the same time well-balanced without the use of transformers. This thing will deliver some very clear sounds with minimum background noise thanks to its amazing headroom and bandwidth (unmatched by many other single-channel preamps out there). The gain ranges from 10 dB to 75 dB and the m101 notably comes with a unique universal switch off, which will take a large range of voltages from 100 to 240 V.
The front panel is designed with a black anodized and laser black surface, which gives us sleek usage in different visual situations (super sturdy for longevity as well). Additionally, all switches come with indicators in LED lights as well as a HPF switch and 48 V phantom power. The Grace Design m101 comes with a ribbon microphone mode that will bypass decoupling input capacitors and raise input impedance in case you’re using that type of mic. As you can see, the Grace Design m101 is definitely one of the best microphone preamp options for near professional usage in the studio or live performances. We’d say grab this over the previous single-channel preamp pick due to the obvious increase in overall quality — just make sure it fits your budget and you’ll be using the features that justify it’s price.
