Fantastic

I wont sit here and say that I have commercial studio quality coming from my home studio after purchasing this unit. But I will say that this stepped my recordings up to a very respectable level beyond the outboard pre's I was previously working with. Everything just sounds "right" through this pre. My K2 through here emits a tangible warmth. The DI with bass is great. I will say i didn't notice much of a difference when running an acoustic DI through the P-solo vs a presonus studio channel (tube all the way down) The only thing I don't like about this pre is the form. Would love some rack ears.... Otherwise, this thing is the best pre you will get for sub $800. Period.

Professional

This preamp will give you the feeling of being in a professional studio. The sounds that I get with microphones and direct plugin with my guitar are absolutely pristine. You don't need to think too long about what preamp to buy. You've found it.

P-Solo

A very detailed preamp. I A/B'd it with a FMR RNP and it was so much richer and detailed that I sold the FMR. I'm now thinking of either getting another P-Solo or a Grace M101 to add to my P-Solo for stereo recording. It's a shame that there is NOT a single comparison between the Grace and P-Solo anywhere. It's like it's against the law to compare the two.If you search the first 2 million google hits of Grace M101 v P-Solo there is nothing. It seems the internet police have kept these 2 preamps from colliding........

A must have

This is absolutely a pre everyone in the industry should have, unless you already have a Martech. Which is the cleanest preamp ever made IMO. But this is literally a small fraction of the cost of a Martech. I don't recommend this to be your only pre, but it definitely fills a niche that you're probably missing out on as you're reading this. I've found this to be the best sounding preamp I've run through for most female vocalists, bass guitars, lower resonance strings, and any room mic or ribbon. (Just add the cloud lifter for ribbons or dynamics). Male vocals is hit and miss with this, it really depends on the voice in that case. I love how long the throw is on the volume knob, it makes fine tuning your gain very easy. Its also a really beautiful piece of gear. These pictures don't do the brushed red metal justice. People who know nothing of preamps will imagine this costing thousands more than it does. Everyone who comes in to the studio always admires it.

Jon Gillespie

Absolutely stunning clarity, and perfect in its simplicity. The P-Solo is the legenday "wire with gain!" Finally a world-class preamp that you can have in your home studio for less than $500. Anyone who wants to get professional-grade quality out of their home studio should have the P-Solo as their money channel!

Dennis Konicki

The PSolo is absolutely stunning. It is extremely quiet, and amazingly accurate. It's a must-have for anyone looking for a transparent mic preamp that delivers a microphone's nuances seamlessly into a system.

Kenny Bergle

The only mic pres imported by Neumann. Stellar clarity and wonderful 'pre'sence! One can't go wrong with a True!

I have a very successful friend in the voiceover industry who swears by the TRUE Systems P-Solo. So when I brought one home, high hopes came with it. Having worked with this friend on a professional level for quite some time, I had some idea of what to expect...His recordings are consistently clean, full and detailed. But this guy has the type of voice that can make a Mr. Microphone sound good. Still, I often wondered why he chose a preamp in this price range, while most of his colleagues are using preamps that cost three times as much or more. Carrying the box up to my studio, I actually wondered if someone had stolen the P-Solo out of the box because it seemed much too lightweight. Unpacking the box was equally as interesting when I discovered that the P-Solo was, in fact, in the box. Pulling it from the box, I had immediate mixed feelings. First, the bright red faceplate is stunning. It's a pretty, shiny piece that anyone would be glad to display in their studio. But it didn't feel right...I'm used to preamps being heavy, awkward pieces. I've even come to a point where I associate weight with quality. While the P-Solo seemed sturdy, at no more than five pounds, it felt too light to have any quality components (or any components at all) inside the chassis. It also bears one giant gain knob dominating the front panel, giving it a unique, but straightforward appearance. TRUE could've gone for a modern look with lots of knobs, dials, switches and lights. Conversely, they could have followed the modern trend and created something that appeared to be made 50 years ago. But they took a different approach and met in the middle with vintage simplicity, married to modern design. In use, the P-Solo connects via a single TRS cable. I started out as I always do, which is by connecting my trusty Audio-Technica AT4040. I know the mic well, which gives me a good basis for comparison between preamps. For recording, I ran TRS into my Soundcraft M4 mixer, which has onboard A/D and S/Pdif out. I monitor with a set of Alesis M1Active 620 monitors and Beyerdynamic DT770 Pro headphones. The headphones, which I've been using exclusively for over five years, are great for listening to the subtle nuances of preamps. I immediately had to back off the gain, as the P-Solo is much hotter than I expected it to be. While there is a ribbon mic version of the P-Solo available, I suspect there's enough gain in the original version to get adequate gain from a ribbon mic or dynamic with a low output level. Once the levels were adjusted, I started recording and monitoring through my headphones, simply reading a basic script into the microphone and recording. The first thing I noticed was a darker sound than I'm used to. Initially, I thought this was a problem, but as I listened more and my ears adjusted, I realized that I'm used to listening to preamps that have some color in the upper midrange and near the top. The P-Solo is essentially colorless, so it isn't that it's a dark preamp, it's just more neutral than what I'm used to hearing. Once I had that realization, I started to comprehend the possibilities for the P-Solo. I typically run everything through a slightly colored preamp. Everything that passes through it (likewise with many other pres I've tested) has that "signature sound" stamped on it. The P-Solo is so transparent, it is not limited by a "signature sound". Think of it like a painter, his paints and his canvas: If a painter always paints on a blue canvas, everything he paints will have a blue tint to it. If that canvas is blank, however, he will have many more options with his color choices (microphones). The P-Solo doesn't dilute the sound of the mic that it amplifies. You can really hear the differences between mics, as I found by plugging in a Shure KSM 44 for comparison. As I used it more, I became more and more fond of the preamp. Nothing about it sounded bad, no matter what I threw at it. In my experience, most preamps have a weakness or two, but from almost whisper soft speaking, to a full scream, to sounds (like the jingle of keys), everything sounded right. The P-Solo is much more flat than flattering, which certainly left me with a lot of freedom for working inside the box. It's an ideal choice for a digital front-end, where color can be added through the use of plug-ins to-taste. I only spent a short amount of time testing the DI. As a DI, it was clean, just as the preamp was clean. On my bass, for instance, a quick A/B with my normal preamp, as well as running direct to a channel on my Soundcraft console proved that, once again, the P-Solo was an improvement over the alternatives. You can use both the preamp and DI, which simply amounts to an added value. The ultimate verdict is that the P-Solo is a rock solid piece of gear. I can't think of a single studio that would not benefit from having a transparent preamp like this on-board. If you're only looking for one good preamp, the P-Solo should be a top contender. If you've got a rack full of colorful preamps, you would be wise to consider adding the P-Solo to your arsenal to handle those "colorless" needs! This is a purchase you'd never regret.
