Remember when we all decided CDs were dead? When we shoved those jewel cases into storage bins and declared ourselves streaming converts, convinced that digital files and algorithm-curated playlists were the future? Here’s the embarrassing part: I have a stack of CDs sitting on my shelf right now with absolutely no way to play them. And I’m not alone. People are still buying CDs, especially in the K-pop world where physical albums are part of the whole experience, complete with photo cards, posters, and elaborate packaging. We’re collecting music we can’t even listen to properly. Pro-Ject Audio’s new CD Box RS2 Tube might actually fix that problem, and honestly, it’s making me want to finally do something about my unplayable collection.
This isn’t some nostalgic throwback designed to capitalize on retro vibes. Pro-Ject built this thing with the kind of serious engineering usually reserved for audiophile turntables. The Austrian company’s latest entry in their top-tier RS2 line is a top-loading CD player with a fully balanced tube output stage, featuring two premium E88CC vacuum tubes that add warmth and fluidity to digital playback. Think of it as the vinyl listening experience but for your CDs. You know that organic, emotionally engaging sound that makes you actually feel the music instead of just hearing it? That’s what these tubes are doing to your digital audio.

What makes this particularly interesting is the SUOS DM-3381 Red Book drive at its core. This isn’t just any CD mechanism thrown into a pretty case. SUOS-HiFi, which used to be StreamUnlimited Optical Storage, was founded by former Philips CD engineers based near Vienna. These are literally some of the people who helped invent CD technology in the first place. The drive uses a BlueTiger CD-88 servo with predictive algorithms that can maintain accurate data retrieval even when your discs are scratched or less than pristine. We’ve all got a few of those CDs that have seen better days, right?
The integrated Texas Instruments PCM1796 DAC is where things get even more interesting. This means the CD Box RS2 Tube can connect directly to any amplifier with analog inputs without needing a separate digital-to-analog converter. The DAC operates in a fully differential configuration and feeds straight into that balanced tube output stage for maximum signal integrity. You get both XLR balanced outputs and single-ended RCA connections, each with its own dedicated output stage, so you can run both simultaneously without any impedance issues. And if you’re the type who already has a favorite external DAC, there are optical and coaxial digital outputs too.
The build quality is exactly what you’d expect from a product in this range. The entire chassis is precision-machined from aluminum, available in either silver or black finishes, and it’s absolutely gorgeous. The top-loading design means you actually get to interact with your music in a tactile way that tapping a screen just can’t match. There’s something satisfying about placing a disc on the magnetic clamp and watching it load. The big LCD display shows track information and CD-text when available, and it comes with a full aluminum remote control that feels substantial in your hand.
Power delivery matters for any high-end audio component, and Pro-Ject addressed this by using an external power supply to keep transformer noise away from the tube circuitry. For those who want to go even further down the rabbit hole, the player is compatible with Pro-Ject’s Power Box RS2 Sources linear power supply upgrade, which can improve soundstage depth and background silence.
What’s really striking about the CD Box RS2 Tube is how it positions physical media not as obsolete technology but as a deliberate choice for people who care about how music sounds and feels. The resurgence of CD collecting, particularly driven by fandoms like K-pop where physical albums are collectible art objects, proves that people still want to own their music. There’s something to be said for building a curated collection that reflects your actual taste rather than what an algorithm thinks you should like. And if you’re going to own CDs, why not finally be able to play them through something that does them justice?
The CD Box RS2 Tube is set to arrive at UK and EU dealers this month, priced at £1,749 or €1,900. US pricing hasn’t been announced yet, but it’s clearly positioned as a premium product for people who take their listening seriously. Maybe it’s time those of us with unplayed CD collections finally gave them the player they deserve.
