The NAD VISO 1 Wireless Digital Music System is a gorgeous high-end\u00a0iPhone and\u00a0iPod speaker dock that\u00a0uses Bluetooth for wireless music playback. NAD says the VISO 1 utilizes a Direct Digital amplifier to eliminate all analogue circuitry for a digital-only performance, and for\u00a0this reason it doesn\u2019t offer an analogue line-in audio port. The gadget has a sleek "ring design" and attractive shape along with simple, intuitive controls that combine for a\u00a0minimalist-yet-elegant audio experience.\n\tSetting up the NAD VISO 1 was simple;\u00a0you just\u00a0remove the\u00a0speaker system from its box and plug the included power cord into an\u00a0electrical\u00a0socket. The VISO 1 noiselessly powers on when you depress the on\/off button\u00a0on its right side. No assembly is required, except for the button-cell battery that goes into the plastic remote control.\n\tThe VISO 1 supports three modes of music playback: From an iPod or iPhone docked to the\u00a0built-in Apple-specific dock; via\u00a0Bluetooth; and via\u00a0an optical-digital input port that\u00a0supports audio\u00a0up to 24\/96k from a TV or external media-streaming device, such as\u00a0an Apple TV. NAD says the speaker, which\u00a0supports the new apt-x\u00a0audio\u00a0standard,\u00a0works with\u00a0virtually any handheld device\u00a0with Bluetooth.\n\tThe Apple-specific dock charges\u00a0your iPod or iPhone when attached, and it can be rotated 90 degrees to hold your iOS device in a landscape orientation.\u00a0And an\u00a0adjustable rubber "gripper" means that you should be able to\u00a0use your\u00a0iOS device in the dock without removing its case.\n\t\tI put the VISO 1 through\u00a0the paces by playing music with my iPhone docked in the Apple dock and wirelessly using Bluetooth.\u00a0Audio quality\u00a0is\u00a0impressive with vocals that come across clearly, though the highs were slightly less pronounced than I would have liked. What impressed me most\u00a0was its ability to produce nuanced bass even at a low playback volume. The low notes become correspondingly more powerful with the volume jacked up, which made watching a movie on my Apple TV 2 and listening via the VISO 1 a\u00a0rather\u00a0enjoyable experience.\n\t\tThe high-quality black cloth that covers the speaker grills looks great and adds an expensive feel to the VISO 1, but\u00a0it also\u00a0attracts dust. And the plastic remote\u00a0control is functional, but\u00a0I found it be\u00a0somewhat finicky for such an expensive speaker. Finally, I was also somewhat disappointed that the NAD VISO 1 doesn\u2019t support Apple's AirPlay wireless technology.\n\t\tNAD VISO 1: Conclusion\n\t\tThough the NAD VISO 1 is unlikely to replace your high-end\u00a0home theatre system any time soon, its excellent\u00a0audio quality\u00a0and powerful bass means it still provides a solid sound experience in an good-looking package. Of course, at $930 it definitely isn't cheap, so you\u00a0may want to at least evaluate other options before\u00a0purchasing the VISO 1.\n\tThe prominent bass reflex port on the left offers powerful low-frequency performance.\n\tThe VISO 1\u00a0has a sleek profile. (Notice the Power button located on the right side of the speaker.)\n\tThe VISO 1's the input\/output options are limited to component video output and optical audio input, but a\u00a0USB port (top) opens the door for future upgrade.
