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.

Favorite jeans ever!
Oh my gosh these jeans are incredible! People are always amazed when I tell them they are from Amazon. The quality is great. The stretch and feel is perfect and they are so flattering. I will be purchasing more. True to size!

My new go to jeans!!!
5'6", 235lbs, my jeans from LB were mostly size 18 - these 18 fit just as nicely if not better. They are a little long but since I wear boots every day working in the construction field, they do not drag. Love the extra high waist. Don't feel like I bare all when bending over. Needed to replace my jeans from a high dollar plus sized company that keep wearing thin in the thigh but hate the $60-$80 price per pair... again... I work in construction. First I just bought one pair. LOVED THEM the first time I wore them. After their first wash, they were just as great. No color bleed and no shrinking. I immediately ordered two more pair. This is the first pair of jeans I have fallen in love with for years due to their comfort. Appear to be of good quality. I think I look amazing in them which is not something I use often to describe myself. Don't appear to stretch too much during wear. I usually don't review products, but I know how frustrating finding a good pair of jeans can be, especially for larger ladies. I am so excited about and happy with these jeans, I just had to share.

Cute, good quality. Wish there were more sizes available.
Size: 20, Color: Iced Blue Light Wash
Only 4 stars because once again, sizing for women's jeans isn't telling the truth/whole truth/nothing but the truth. I can wear a 20 in other jeans and they're sagging on me by midday. Some 20's feel like 18's. I don't know man. But sizing aside, these jeans are SUPER cute. And I just know that when I am able to sit in them without suffocating ... ladies, you know what I'm saying 😆 ... they're going to be so comfortable too. The material feels like really nice quality. They aren't true high rise but high enough to hold everything together. More like a medium high rise. I was really bummed they didn't have a 22. But I guess this is incentive. I'll order some amazon exercise clothing and work out until these fit me. I'd say they're on the 1/2 size too small of being true to size. But that's not really a fair assessment when no two different brands of jeans are the same in any capacity. If you're positive what size jeans you wear then I 100% recommend these. I can't wait to fit into mine.

Must buy. Flattering and comfortable
Size: 8, Color: Classic Medium Wash
Great fit! These jeans are the most comfortable jeans I have purchased in years. Fabric is soft and has some stretch so my the end of the day you are not feeling like a sausage. The cut is very flattering and the quality is better than many of the more expensive jeans on the market.

Great jeans for this price!
I was hesitant to buy jeans on Amazon but I thought I'd give these a try since I've had trouble finding a boot cut jeans that I liked. I ordered my true size 29" waist, size 8 regular length and they fit true to size for me. I'm 5'3" so I have to wear about a 1" heel, which I like for a boot cut. They have a decent amount of stretch (but not too much) so they are very comfortable. Wearing these with heels makes my legs look nice and long so they are really flattering. Mine are dark blue rinse and I'm going to buy another pair in black because I like these so much! Good job, Amazon
