X-TUBE

Tube Output Buffer

  • Adds tube-like tonal character, depth, and richness to every digital and line source
  • 2 × E88CC triode tubes

Impedance Matching Amplifier

  • Maximises signal transfer
  • Reduces distortion caused by incorrect impedance matching

Additional Benefits

  • Protects your amplifier from reactive loads

Superior Mechanical Design

  • Built in a precision-engineered extruded aluminium chassis with excellent resistance to resonance
  • The X-Tube was the first product in Musical Fidelity's X-Series range

Features

  • Improves the performance of digital and analogue sources
  • Particularly beneficial for budget digital, streaming, and CD sources that use all-in-one chip designs and lack proper output stages
  • Provides optimal impedance matching between preamplifier and power amplifier when required
  • Direct mains input with external power supply support for a clean installation setup

We are proud to unveil the X-Tube – a revolutionary tube output buffer built with our newly reimagined X-profile aluminium die-cast chassis. This innovative design marks the return of the X-profile configuration, a distinctive element in the revered Musical Fidelity X10D tube output buffer and promises to breathe new life into a wide range of future audio electronics products.

From X10D to X-Tube

The X10D, as designed by Musical Fidelity founder Antony Michaelson, is an acronym – or if you want “a wordplay” – for eX10[tend]ed. The internal circuitry design faithfully follows the original and just like it, the new X-Tube extends your signal chain and is connected between input source and amplifier.

It serves as an intermediary stage and is designed to enhance audio signal quality and add tube-like tonal characteristics to your line sources. Connectivity is simple, featuring 1x RCA input and 1x RCA output as well as an RCA bypass. The old external power supply has been reworked and moved into the chassis itself, allowing for a cleaner setup than before.

Advantages of a Tube Output Buffer and its Impact on Sound

Tube preamplifiers or tube output buffers hold a special place in the hearts of many audiophiles offering a distinct sonic signature that is prized by many audio enthusiasts. The warmer, more natural sound, improved dynamics, and potentially reduced listening fatigue contribute to a unique and engaging listening experience.

The X-Tube in Today's Audio World

What is the place of the X-Tube in today’s audio world? We currently observe a surge in a new generation of affordable streaming devices and DACs. Even CD-players receive increased interest as people are holding on to their old collections.

These modern digital audio devices achieve great price points, but do this at the sacrifice of hardware. Software makes up most of the cost and there is no budget assigned to, amongst other things, proper output stages. Instead, cheaper integrated IC solutions are used that don’t have the power to properly drive line inputs in many amplifiers.

The X-Tube has a clean, high impedance tube input, meaning it won’t put as much strain on the output device capabilities of connected source devices. Regular line inputs on most amplifiers are usually more demanding and cheaper output stages will struggle.

On the output side, the X-Tube’s clean, low impedance tube output buffer has plenty of drive and will not struggle with any low or high impedance amplifier input.

The X-Tube is designed to be the reliable core of your system, enhancing modern streamers and keeping pace as digital technology rapidly evolves.

While streamers excel at software and deliver great digital-to-analogue conversion with the latest DAC technology, they often fall short when it comes to analogue output potential. And when their analogue drive is lacking, the X-Tube complements them perfectly.

beautiful and sturdy
Size: 48 inch 2 Tier
The shelf is beautiful and sturdy. The only small complaint are the instructions to put it together are deceiving because pieces were put together for shipping purposes (we assume) but didn't actually go together which took us a few times to figure out. I recommend putting it together off the wall before trying it on the wall so you know what pieces go where.

Cheaply made
Size: 48 inch 2 Tier
I would not recommend this shelf. There are no instructions included - just a simple drawing of putting it together but nowhere says what drill bit size to use for the plastic anchors which are square on the end and not round. In addition, you cannot fully tighten the iron brackets or they won’t alight on the wall to hang the shelf. Each piece of metal piping has part of the black coating stripped off as well. And on top of that, the bottom of each shelf is unfinished and looks as though they used a filler to hide holes in the shelf. Not worth the money or the hassle.

Good shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space. It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅 Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost. Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!
