"The top plate logo is engraved into the aluminium. The face plate and side panels are finely brushed CNC'd Dupont Corian to not prevent Bluetooth reception range for the remote app. The user can easily change them and the knobs and buttons to customize the look. Next year I plan to offer a few more colourful options for those who want to make a statement. The top plate is easily removed via two thumb screws on the rear panel that hold it in place. It slides in/out on CNC grooves on the side panels. Thumbscrews will also hold the module back plates in place on the rear panel. The user will not even need a screwdriver to install them. On the front panel there is a master power button for the system and one just to turn off the power amp stage when listening to headphones. This is not done via a relay in the signal path but via grounding the gates of the Mosfets to 'mute' them. The front panel knobs are attached to rotary encoders. The headphone jack can either be a 1/4" jack or a 4-pin XLR. The headphone amp module has both outputs so the user simply installs the jack of choice and plugs that into the headphone module. The included remote control handset has lots of functionality such as system power, volume up/down, mute, display mode, balance L/R, input select, DAC phase/filter and more." Or as former contributor Frederic Beudot put it in an email who works in upper management at DuPont: "Vinnie. Okay. Where do I place my order? I have been looking around for something like LIO for over 6 months but there was always something missing. Either I could get the phono but not a DAC; or a DAC but no phono; or more often than not it was not modular and future proof (which on a DAC is insane to be locked in forever). Or it had compromised preamp functionality; or a compromised amp; or way too much power and damping for my Ocellias. I hope Vinnie is not going after a market of just me - but he has me. And the front is made of Corian by DuPont. Now how much better could it get? Do you think he could license a SIT2 module from Nelson and stick it in there? -:)"

Vinnie: "You are correct about the AVC module not being an option in conjunction with the tube stage. That's because the AVC module fits in the same location. We had to do it this way or else it wouldn't all fit. Those AVCs are large and there is one per channel. One AVC takes up the approximate space of one tube and its associated circuitry. Also, the modules need to go in their assigned locations, hence we cannot replace the phono stage module with the AVC module for example. This has to do with the different i/o for each module. For instance, the DAC module sends out data to the front panel board for display views of the sample rate of the track being played, phase (norma/inverted); and the DAC module is fed input lines to select the input (USB, coax, optical). All of these i/o paths are different for each module."


"The modules are also of different sizes. Some need to be larger than others. If we made them all the same interchangeable size, the outer box would have to be larger. I wanted to keep it to a size of ca. 17" W x  12" D. The PURE-DC-4EVR board with the ultracaps and charging/monitoring circuit takes up about half of the total internal space already. And that's with the AC/DC conversion done externally via a power adapter. The other half is the 'motherboard' which all the modules plug into. We also assigned their locations to create the shortest possible internal signal paths. I need to make you a top view diagram that shows where they all go.  


"It's really slick because if one just orders a DAC, then that board is right next to the 'outputs' board with the Cardas RCA jacks. If one adds the tube stage or AVC to the DAC, those go right behind the DAC board and then feed to the outputs board. Long story short, if one orders the AVC, it eliminates the RVC and tube stage from the option menu. The choices are either passive volume control via resistor or autoformer module; or active with the RVC followed by the tube stage.


"For those who do not want tubes in their system, the AVC is the highest quality but most expensive option. As you already know, when it steps down the voltage to attenuate, it steps up the current. So it does a remarkable job of preserving fine detail at lower volume levels. The RVC is no slouch either though and offers excellent tracking between channels. It will outperform any potentiometer and is of the same quality as the very best stepped attenuators. Even so the AVC does make for the ultimate passive volume control solution. RVC + tube stage brings valves into the equation. Whilst they move away from the neutrality of the AVC, they provide more dimension to the sound along with the ability to fine-tune the sonic flavour via tube rolling which many enjoy. So there's something here for everybody."
