Q I have tried streaming Amazon Music HD to my Marantz SR7015 receiver over Bluetooth from my iPad using the receiver’s HEOS app. The app shows resolutions all the way up to 24 bit/192kHz — something I didn’t think was possible with Bluetooth! Will I get the same resolutions if I make a hardwired connection from iPad to AVR using an AudioQuest DragonFly Red USB DAC? —Paul Giovino, via email

THE VERDICT
If you're looking for an ultra-large screen to pair with your ultra short throw projector, the DarkStar UST 2 Efinity offers impressive performance and value.

With ultra short throw (UST) projectors available from a growing list of companies including Epson, LG, Hisense, Optoma, Vava, and now Samsung, it's clear that the category has become firmly established. That's no surprise given the ergonomic and screen real estate- per-dollar benefits such models offer, but getting the best picture quality from a UST setup requires a specific screen pairing. We've frequently discussed ambient light rejecting (ALR) screens in Sound & Vision and have reviewed a fair number of them. But a UST projector requires a specialized type of ALR screen—one like the DarkStar UST 2 Efinity from EPV Screens.

Q My partner and I want to get set up for high-resolution audio and are hoping to use the Tidal service for better-than-CD-quality streaming. We have a Sherwood stereo integrated amplifier from the 1980s, along with big, beautiful, fantastic-sounding speakers and we don’t want to give those up. I’ve tried researching the huge range of available tech options but just don’t know how to make it work. We use Android devices and own a Fosi Audio DAC-Q4 [digital-to-analog converter/headphone amp]. We also have a spare computer that can be used to run Tidal. —Victoria Baker, via email
