D 3045 Hybrid Digital Amplifier
HIGHER FIDELITY
High Res is to audio, what High Definition is to video. It is more lifelike and natural, and an altogether more enjoyable listening experience. With features like Master Quality Authenticated (MQA) the D 3045 can faithfully and accurately reproduce the full spectrum of sound encapsulated on the Studio Master. Until now, music lovers have only been allowed to hear an edited version of the full fidelity because our delivery systems, be it tape, vinyl, or CD, did not have the capacity to hold all the information contained in the Studio Master recording. With High Res downloads and streaming we can now enjoy exactly the same experience the artist heard in the studio when the recording was first made.

AMAZING CAPABILITY
We recognize that just because there is a new better format available doesn’t mean your present music collection will be discarded – far from it. So we have included all the inputs and circuits required to listen to all your current music, while also possessing the capability to fully exploit today’s best High Res sources. Especially notable is the Asynchronous USB input for attaching a computer which allows High Res streaming using one of the several High Res programs like Roon, JRiver, and Amarra. Asynchronous operation uses the D 3045’s precision clock (instead of the computers clock) to reduce jitter to a minimum and make the USB format work ideally for audio. For everyday convenience we have included Bluetooth wireless streaming featuring aptX HD, the latest 24-bit High Res version of Bluetooth that is being supported by more and more phones and tablets. Additionally, if you have Bluetooth headphones, you can also stream your non-Bluetooth sources wirelessly to your headphones, or you can plug in your wired headphones to enjoy the exceptional performance of our low impedance, high current, Headphone Amplifier.

FEATURES YOU WON’T FIND ANYWHERE ELSE
Love vinyl? The D 3045 features NAD’s super accurate, wide dynamic range, Moving Magnet Phono preamp to extract every last morsel of sound from your LPs. If you still play CDs, we have both analog and digital inputs. The digital inputs allow use of the advanced High Res DAC built into the D 3045. You can even send the sound from your TV to the NAD and seamlessly control the system using your TV’s remote by taking advantage of the HDMI ARC input. Complete your system by adding a subwoofer with the convenient Sub Out jack.
