Mixing Music | Music Production, Audio Engineering, & Music Business

Fair warning: Dee Kei opens this one by saying he doesn't know if he's going to release it. Congratulations — you found it.
This is a looser, more speculative episode than usual, and that's exactly the point. Dee brings a theory he's been sitting with: that the rise of AI tools and plugin saturation is quietly driving a resurgence in the value of analog gear — not because analog is objectively better, but because it represents something that AI fundamentally can't replicate. Humanness. Randomness. The chaos of a real circuit doing something slightly unpredictable.
Lu, who has personally moved over $157,000 in analog gear sales and spent years tracking sold listings on eBay and Reverb, brings the market perspective. They get into which pieces actually hold their value (vintage preamps and compressors from the right era), which ones don't (anything mass-produced and recently released), and the old idea that buying the right gear is just another savings account you can twist the knobs on while you wait.
From there the conversation opens up into some bigger territory. They talk about the current bubble of vintage mixer restoration and servicing companies popping up, what vibe coding is doing to the plugin marketplace, and how AI tools are being deployed very differently in live sound versus the studio — including a breakdown of the L-Acoustics source intelligence system and how it can achieve up to 40dB of feedback reduction in real time on a vocal channel. The episode wraps with Dee going full speculative: the Gartner hype cycle and where AI actually lands when the bubble pops, what nuclear fusion does to the cost of running AI at scale, and the two technology shifts he thinks will fundamentally change everything about how we make and experience music.
It's the kind of episode that happens when two engineers with too much on their mind decide to just talk. The industry context makes it more interesting than it sounds.

Lu brought the topic this week — and it's one of the most universally felt things in audio that nobody talks about directly: the feeling of not belonging in the room. Not because you don't have the skill. Not because you don't have the credits. Just because the feeling is there, and most people let it make the decision for them.
The episode opens with Lu sharing what he keeps hearing in consultation calls — talented engineers at every level passing on sessions they would have handled just fine, because they didn't feel ready. Dee and Lu are direct about it: the gap between someone who is working and someone who isn't is almost never the quality of their mixing. It's almost always confidence and forward motion. They unpack what imposter syndrome actually looks like at different stages of a career — not just at the beginning, but also at the mid-level, when asking for help or shadowing someone starts to feel embarrassing in a way that holds people back just as much.
From there, Dee reads from Daniel Kahneman's Thinking Fast and Slow — specifically the chapter on cognitive priming — and the episode gets genuinely fascinating. He walks through the Florida Effect study, where participants subconsciously primed with age-related words actually walked slower down a hallway without knowing it. Then the pencil experiment, where people forced into a smile by how they held a pencil in their teeth rated cartoons as funnier than those forced into a frown — without being aware their facial expression had changed at all. The implication is direct: acting calm and confident doesn't just make you look calm and confident to others. It statistically makes you feel calmer and more confident yourself.
The conversation also takes an unexpected turn into money priming — how the mere presence of money-related imagery in your environment makes people measurably more independent, more self-reliant, and also more selfish and socially distant — and what that means for the environments engineers build and the mindsets they carry into sessions.
It ends where it started: the feeling of not belonging is not evidence of not belonging. Send the email. Ask to sit in. Shadow the session. The only thing making the street look longer than it is, is you.

This episode starts with a confession: Dee Kei wants a new compressor. Specifically, he's been eyeing the Heritage Audio Grandchild 670N — a $3,000 stereo Fairchild-style compressor in a 5U rack unit that launched in late 2025. From there, the episode opens up into something much more interesting than a gear review.
Dee and Lu walk through exactly what makes the original Fairchild 670 so mythologized — the tube count, the time constants, the maintenance costs that make owning one feel like buying a second car you're afraid to drive — and why Heritage Audio's approach of distilling the circuit down to four tubes in an affordable, modern form factor is either brilliant or sacrilegious, depending on who you ask. They break down what the Grandchild 670N actually has on the front panel — DC threshold, AC threshold, sidechain filters, mid-side and stereo linking, true bypass — and why $3,000 for two channels of Fairchild-esque compression is a genuinely different proposition than it was even three years ago.
But the most interesting part of the episode isn't the gear. It's what happens when Dee reads from two actual peer-reviewed studies on whether listeners can hear the difference between analog and digital processing at all. The first study tested analog modeling plugins against free non-modeling alternatives across 540 participants — and found that not only did listeners show no preference for the analog mix, the majority who thought they could identify it were wrong. The second covered DAX differences using a loopback method with over 1,300 respondents. The conclusion: people largely can't tell the difference, and the majority who claimed they could were misidentifying what they heard.
So why does any of this matter — and why does Dee still want the compressor? The episode lands on something more philosophical than a gear recommendation: the difference between buying hardware because you believe it's objectively better, and buying it as an act of devotion to the craft. Dee draws a sharp distinction between using gear purchases to fill a hole in your love for music versus buying from a place of already loving it deeply — and how Tony Mazzarati still sharpening techniques at his level is proof that the rabbit hole never ends for people who genuinely want to go deeper.
Gear talk, research, psychology, and the irrational passion that keeps working engineers working. A lot going on in this one.

Lu's on vacation. Dee Kei is alone with a page of talking points and one of the most contested topics in audio engineering right now — and the result is one of the most thoughtful solo episodes the show has produced.
This is not an episode about which AI tools Dee uses or recommends. It's about something harder to talk about: how engineers think about delegation, what happens when a probabilistic recommendation gets presented with the confidence of certainty, and why the pro-AI vs. anti-AI binary is the least useful frame anyone could bring to this conversation.
Dee opens with a distinction that reframes the entire debate: there's a difference between assistance tools, delegation tools, and full replacement — and most of the discourse collapses all three into one. He argues that engineers have been using automated decision-making for decades (dynamic EQ, auto release, delay compensation, drum replacement, LUFS metering), so the real question was never whether machines should make decisions. The real question is how much of the contextual, consequential decision-making we're comfortable handing over — and whether we understand what's being lost in that handoff.
From there he gets into the value engineers actually bring that no AI is accounting for: accountability, history with an artist, taste, creative confidence, the ability to hear the same note as a client and understand what they actually mean. He's direct about the economic effects coming — fewer junior engineer jobs, faster turnaround expectations, clients arriving with better rough mixes — but equally direct about what those changes don't mean: that the ceiling of professional audio work is getting any lower.
The episode closes on a question Dee leaves deliberately open: if an AI assistant could eventually make every technical decision as well as a human engineer, what do we actually believe the mixer is there to do?

Before you do anything else, pause this episode and go take the Big Five personality test at https://bigfive-test.com/ — it's free, open source, and it's the entire point. Dee Kei and Lu share their results live on the show, and if you don't know your own numbers, this episode won't hit the same.
The Big Five — also called the OCEAN model — is the only personality framework that psychologists actually take seriously. Unlike Myers-Briggs and 16 Personalities, which studies have found are closer to horoscopes in predictive power, the Big Five is clinically validated, cross-cultural, and remarkably consistent over time. Dee breaks down exactly why — the difference in test-retest reliability, the Barnum Effect, and what it actually means to score on a continuous spectrum instead of being dropped into a binary personality type.
From there, the episode gets into the part that's most relevant to anyone building a career in audio: what each trait actually predicts in a professional creative context. High neuroticism and how it maps to taking client feedback personally, spiraling on revisions, and undercharging to avoid confrontation. High conscientiousness and how it shows up differently in recording versus mixing workflows. The relationship between openness and musical taste — and why, despite what you might assume, personality and music preference are barely correlated at all.
Then Dee and Lu read their actual results out loud — and it gets surprisingly candid. Lu's strengths and blind spots, including the gap between his external warmth and his internal sensitivity to criticism. Dee's near-perfect openness scores, his low cautiousness, and why his directness can sometimes outrun his warmth in ways people misread. The moment where the AI-generated analysis of Dee's personality is so accurate that he and Lu both go silent.
It's equal parts psychology, self-awareness, and career development — wrapped in one of the more honest conversations the show has had.
