About

How do you follow up one of the most successful products in the history of a company? With a product that improves upon the original in every way, and the Boulder 866 Integrated does just that.

Power is up to 200W per channel. Manufacturing is substantially more efficient. Weight has been reduced. New circuitry gives you greater current output at maximum power. External IP control has been added. There are versions for traditional systems as well as modern streaming media users. And a dedicated Boulder app easily enables you to manage everything.

And here’s the best part: the sound is everything you would expect from a Boulder. It’s powerful, clean, clear, quick, and true to the sound of the original recording and the intents of the artists involved. In fact, there’s absolutely no reason not to take home an 866. It’s everything you could want and more.

FAQs

Please read our FAQ before sending us a message.

How is my order processed ?

Once we have received your order and your payment, we issue you an invoice that will be mailed to you with a reference number for your order. Once your order is ready : it will be dispatched to you with insurance and tracking number.

Which payment methos are available in the Online Shop ?

You can choose between Paypal, bank transfer or Credit Card. Please take in consideration that payment via bank transfer will slightly delay the processing of your order as we have to receive your funds on our bank account to confirm your order.

Why are there different estimated delays prior to sending for some of the products

One of the politics of Ana Mighty Sound  is that every order is unique and made for a single customer. You will find next to each item an estimated delay prior to delivery. We will do our best to fulfill it before this delay (and most of the time we do).

Please keep in mind that we are a 100% human company working all over the Old World (Europe) and that we do commit to deliver you the best made / best quality product available, and to insure that : this can take some time.

Of course… some of our products are in stock !

Can I specify a courrier for my order ?

Yes you can ! Just drop us a line in the « additional remarks » of your mail order. This may add additional fees to your order. We can work with DHL, TNT, FedEX, UPS, French La Poste or Chronopost.

What if I have received the wrong item ?

In the very unlikely case this would happen just send us a photo of what you received and we will send you a courrier to fetch the item back. Once we have checked it out, we will send you the correct item.

My items are not up to specifications, what should I do ?

This is highly improbable as we use the most modern techniques to insure that our products are up to specs. In fact we even have a dedicated person checking that every single item is in perfect condition prior to shipping. Of course it can happen, but we doubt it seriously. In any case if you were bothered by something : just send us an email and we will sort it out with you.

I am very happy/disappointed with my order and I want you to know it ?

Please do not hesitate to drop us a line and we will be always happy to answer all of your requests. Our aim is your complete satisfaction.
