Q I recently built a pool house next to my backyard pool.  I used to listen to music poolside by spooling Ethernet cable to a wireless access point located in the bushes outside, streaming tracks from my iPad to a portable Bluetooth speaker. With the new construction, however, I plan to connect outdoor speakers to an AV receiver located inside the pool house. For the receiver, I’m looking at Onkyo’s TX-NR545, which has built-in Airplay and Wi-Fi along with Bluetooth. Here’s my problem: I don’t think the Bluetooth range from my iPad will be sufficient to reach the AV receiver inside the pool house. Can I tap the Onkyo AVR’s other wireless capabilities to stream music using the iPad? —John Reebel

Q I own a Sony BDP-BX57 Blu-ray player that can play SACDs. I also own a Pioneer VSX-820-K AV receiver that can only decode two-channel DSD signals from SACDs via its HDMI inputs. To get the best performance when playing multichannel SACDs, should I set the HDMI output on the Blu-ray player to bitstream? Also, which of the following listening modes on the AVR should I choose: Auto Surround, Direct, or Pure Direct? —Chris Murphy / via e-mail

Q I am finally upgrading my Pioneer Elite receiver and plan to replace it with a new model that has HDMI 2.2 inputs. Unfortunately, the new receiver that I have in mind lacks a phono input. To get that feature, I’d have to fork over $500 more for a step-up model. Is there any way to use the phono preamp in my old receiver and hook it up to the new one? Also, how good are the built-in phono preamps in receivers compared to standalone models? —Kevin Olds /Via e-mail

Q I’m on a vinyl kick. I recently purchased an Audio-Technica LP120 USB turntable and am converting a few of my old LPs. I have it connected to a Sony AVR and am listening through my Klipsch Reference RB-5II bookshelf speakers. Now I’m thinking about searching for a vintage amp or receiver. I’ve read good things about the Marantz 1060 integrated amp (circa 1975), which is rated at 30 watts per channel. I also hear good things about some of the old Pioneer gear. I want to crank old classic rock, and I know the RB-5IIs can handle it. Any suggestions on what I should set my sights on? — Lew Collins/Via e-mail

Q I recently purchased a Bose SoundTouch 130 soundbar and have a Samsung BDP7500 Blu-ray player connected to it. Here’s my question: There’s a setting in the Samsung player’s menu for speaker size and distance. Since I’m using a soundbar that gets calibrated using a headset in five positions, is it necessary to also adjust the Blu-ray player’s speaker size/distance settings, or should I just leave those alone? I called Bose tech support, and they had no answer for me. —Peter Palagonia/Las Vegas, NV

Q I have a Denon A/V receiver hooked up to a 5.1-channel speaker system. The setup works fine for movies, but every now and then I want to listen to good ol’ stereo recordings ( I have a modest collection of CDs stored as Apple lossless audio files).  I am tempted to purchase a high-end integrated amp for just this purpose. Which gets me to my question: Can I hook both my receiver and the integrated amp to my front L/R speakers? —Nick Gruin
