It has a resolution of 32-bit/384 kHz sampling rate and can play DSD256 files of up to 12.3 MHz. Featuring output connectors such as 3-pin XLR, 4-pin XLR, 1/4", and 4.4mm Pentaconn sockets, the amplifier is also equipped with several input formats to easily connect your headphones to the amplifier.
The HDV 820 performs with digital sources via optical, coaxial, or USB sources and has balanced XLR and unbalanced RCA analogue inputs. This amplifier is designed to complement Sennheiser's high-end headphones range and offers higher resolution and ultra-low distortion, which opens a whole new listening experience for the most demanding audiophiles. Additionally, a power cable is also included.
When Taron and Andrew Lissimore started headphones.com, they wanted to create the headphone store they wished existed. As headphone enthusiasts, they dreamed of a store with 365-day returns.
So they decided they were going to try to make 365-day returns work - no matter how ridiculous it sounded to their friends.
Years later, they're still doing it, and their friends still think they're crazy.
So take some time to get to know your new gear. We want you to enjoy your purchase for years, not just a few weeks. If you're not satisfied, you can return items in like-new condition for up to 365 days.
Returning is easy - Start by filling out this form https://returns.headphones.com/. Please include your serial number and a detailed reason for your return. If you do not provide a return reason, your return may be rejected.
When your return is accepted, an instant store credit will be sent along with a return label. You can use the instant credit to make another purchase right away. If you prefer a refund to your original payment method, we will process the refund to your original payment method once your item has been received and inspected by our team. The inspection process can take up to 5-7 business days.
Once you have received your return label, you have 7 business days to drop off your return. If your return has not been dropped off at the courier within 7 days, an additional 30% restocking fee will apply. If your return is not dropped off within 30 days, your return will no longer be accepted.
To avoid additional restocking fees, your item must be in like-new condition with its original packaging. It must also include all original accessories and manuals. Please add a larger shipping box to protect the original packaging during shipping. The cost of the return shipping will be deducted from your refund.

Special order items are non-cancellable and non-returnable. Special order items may ship earlier or later than the estimated shipping window and this will not be accepted as grounds for cancellation.
In order to provide a 365-day return policy, we need to take abuse seriously.
We reserve the right to refuse orders from customers we believe have abused, or will abuse, our return policy, at our discretion. This includes customers who spread returns across multiple accounts.
We made our return policy to help you find gear you feel great about for a long time. Most people use it exactly as intended. We don't want the handful of people who attempt to abuse our policy to ruin it for everyone else.
One of the key things we pride ourselves on is our customer service and one of the most important aspects of our customer service is getting you your product on time! But not only do we want to get it to you on time, we want to make sure we are using a reliable courier so the experience for you is the best possible. That is why we ship all of our orders with FedEX.
While couriers like USPS are tempting because of their low cost, we have found that they are not a good experience for our customers. Nobody wants their package to not be delivered and then have to spend an hour on hold with the local post office trying to get information. To that end, all of our packages are shipped signature required with FedEX to make sure your package arrives in your hands safe and sound and if there are any issues, your time isn't wasted.
However, if you are looking to ship to PO Box or APO address, we can definitely accommodate your shipping needs!
