Integrated tube stereo amplifier with tube phono stage and HD bluetooth

Our Silver 6011 amplifier represents the fusion between the best sound of the past with today’s effectiveness. We have combined the warm and defined sound of audio valve technology and the use of turntables with today’s audio-wireless Bluetooth solutions. Everything powered by a Class-D power stage that multiplies the good design of our preamplifier.


Pure warm and sensitivity sound

Best option for begginners on stereo tube amplifiersbecause no maintenance is necessary on the tube set, as habitual for example, the bias current and the low life of the power tubes in standard music tube amplifiers. In this case you have 4 selected preamp tubes with a time life of around 10 years. Just power on and enjoy your music.

Tube phono preamplifier.

Vinyl lovers welcome. You can plug your turntable to an authentic audio valve circuit, just as the ones used at vinyl’s golden years. You’ll first notice a clear and strong sound that will be followed by hours of enjoyment listening to your records. Turntable phono tube audio preamp. MM cartridge.

High Definition Bluetooth

We also have included a Bluetooth circuit so you can listen music wirelessly using your smartphone, tablet, iPhone, iPad, PC, Mac or any other Bluetooth device. It isn’t a simple Bluetooth connection, it is a circuit that implements Qualcomm aptX technology and provides a high definition audio experience.

Selected Electronic Manufacture

In order to deliver the best sound response and durable electronics, we rely on components from brands like Nichicon, Vishay, Xicon, Tung-sol and JJ-electronics.

Craftsmanship for you

Handcrafted with real wood cabinet. We craft one by one the cabinets. The wood grain is something natural and random, that is why, each unit of Silver-6011 is unique.

Tube Equalization

It is not easy to find tone control in today's tube amplifiers, often because of a simplified audiophile character, sometimes because of a lack of good design. This bass and treble control is based on good vintage studio EQ stages, which respect a 50% flat response and have exquisite control over each filter band without interfering with the rest of the frequencies. Soft touch to enhance the music to our preference.

Versatile inputs

The 4 audio inputs are necessary in order to use the amplifier as your tool for listening to music or watching movies. The two auxiliary inputs (AUX 1, AUX 2) thought to be used with devices such as CD player (highly recommended), television, DVD / Blu Ray player or any game console.

High-end quality connectors

Solid and heavy gold plated connectors. The same connector quality as the most expensive audio amplifiers are used in the Silver-6011. Any signal cable and speaker cable will have the best connection properties, for a non lose tone.

In addition, the buttons on the controls are made of solid aluminium, giving us a good weight and a real feel over the controls.

Efficient Class-D power stage

Everything powered by a Class-D power stage that multiplies the good design of our preamplifier, and bring music to live thru the loudspeakers.

(…) I connected it to a pair of Elac 6.2 and listened to music via bluetooth. A couple of things I noticed right away: 1) the bluetooth works great. It paired with my iPhone immediately every time I turned it on. 2) The sound quality is amazing for rock/country listeners. There is some coloration, but in a warm and pleasant way. Vocals stood out in the mix, almost as if I was listening to a live performance. The stereo separation was really good, and the addition of the bass / treble controls made it easy to dial in my room. Highly recommended.

Off the Charts Value. Let me just say this. I have been buying audio gear for over 35 years and worked in the hi end audio industry for 10 of them. Owned upwards of 30 pairs of speakers and 15 amps and have heard almost everything . This little integrated from Xtonebox is off the charts amazing! Its liquid, warm and has a ton of detail and even though its only rated at 35watts it is extremely dynamic and plays loud. That said, this is the last amp i will ever buy (never thought those words would come out of my mouth lol)

Pros: Sounds amazing! Liquid, warm and dynamic. Beautiful vintage look. Built like a tank with metal knobs that feel great Phono stage is the best I have heard. The bluetooth sounds great too. This may be the best value in all of HI Fi

Cons: No remote (but that would have drove up the price and possibly effect sound quality, so really not a negative. Besides if you're into vinyl you're getting up to change the album anyway)

This is a very good product. Xtonebox did a fabulous job in making the amp sound very natural, with none of the harshness sometimes associated with class D amplification. In addition, the phono pre amp is also included and is designed with vacuum tubes. Vinyl records sound great here. Presently, I am matching the Xtonebox Silver 6011 with Whaferdale 80th Anniversary speakers, this is a great combination in a small room (…) and the real wood enclosure makes this amp look fantastic. Very happy with this purchase.


Such a high quality and well designed integrated amplifier made in Galicia (Spain). I feel very proud to have an HiFi equipment of this quality made in my land. Great job @xtonebox !

If you’ve been eying this thing, just get it.
Nice little amp. Good way to get introduced to tubes and specifically tube pre amps. Build quality is nice and looks great, happy with the purchase. Looks and sounds good.

The excellence of sound. It's a marvel in every way, for the main thing (which is, after all, the sound quality for my turntable) and the design (the vintage aesthetics are fabulously elegant). So far I haven't tried the bluetooth, it has just arrived and I've only been playing vinyl. And the truth is that I'm very happy with that alone. The sound is pristine and crystal clear, with the warm touch that the tube preamp gives it. 100% satisfied. I have to admit that at the price I paid I had my fears and doubts, I didn't know the brand, if it would be a good buy. I did some research on the internet about the manufacturers and I don't regret it, a jewel.
