“All you need to do is plug the Astral 16 into your router, get the processor’s network address from the front display, type that into your browser and you’re good to go. The resulting screen gives you a choice of Remote or Setup, with the latter password protected. The Remote option provides all the controls you need to operate the processor and amplifier on a day-to-day basis. Conversely, the Setup option allows you to drill down into the menus, configuring and fine tuning the Focal.
The reason the Setup option is password protected becomes obvious as soon as you access it. The Astral 16 offers the kind of configuration flexibility only found on very high-end processors, and once fully set-up by a professional installer they will doubtless want to avoid any unwanted fiddling by their customer. However, if you’re a gifted amateur and want to set the Focal up yourself, you’ll have a field day playing with all the features and options.”
“For streaming, the MRX-720 uses DTS Play-Fi, which in addition to making it Alexa compatible, enables it to stream Tidal, Pandora, Napster, Spotify, SiriusXM, iHeartRADIO, DEEZER, Internet Radio, kkbox, Juke!, Amazon Music, BBC, ESPN and NPR.
Of course, should you have a library of digital titles, DTS Play-Fi will allow you to playback FLAC, WAV, ALAC, MP3 and AAC supporting high resolution files up to 24/96.
Just like every other audio company, Anthem has also dipped its toes into the wireless/Bluetooth speaker waters1 via parent company Paradigm. The MRX-720 is compatible with Paradigm’s PW-600 and PW-800 wireless speakers.”
Dirac Live room correction, added by the AM 17 module, is combined with a new calibration microphone and software available for either Windows or MacOS. The implementation is identical to other manufacturers such as Arcam, taking nine measurements to produce detailed EQ graphs.
Dirac then applies target curves using supercomputer wizardry to flatten the frequencies and tighten up the impulse responses. The result is an incredibly neutral performance, with individual sonic elements clearly defined, and the overall soundfield retaining a wonderful sense of balance and cohesion.
While Incredibles 2 didn’t have quite the spark that made the original movie so great, there’s no denying that the opening nine-minute sequence when The Underminer robs a bank in Metroville is a fantastic home theater demonstration. With the combined sounds of the Underminer’s tunneling machine and money vacuum, the Incredibles’ attempts to stop him, and a jazzy music background all going at once, this sequence can give any audio system a real workout. The Theater 7 maintained its composure throughout the clip, with dialogue remaining clear and fully resolved. Even without benefit of a subwoofer, the combination of the Krell amp and the Synchrony One tower speakers managed to get the walls shaking in my 14 x 16-foot theater room.
After taking into consideration “Krell watts” versus what you get with more typical power amps, 105 watts-per-channel can still be a limiting factor in some larger rooms, especially when inefficient speakers are used. Personally, I’m more of a quality over quantity kind of guy, and I’d always go for an amp like the Theater 7 over a lesser alternative with a higher power output specification. In my setup, I never felt like I was running short of juice. (Of course, if you want to have it all, Krell also offers the 7 x 200-watt Chorus 7200XD amplifier.)”
“Viewing the same scenes using the AVR850’s built-in amplification revealed the benefits of its Class G implementation, which is essentially a hybrid of Class A and Class AB. I felt the Arcam’s own power revealed improved transparency when compared to the IOTA, thus retaining a better sense of reality. Having said that, the AVXP1 gave an excellent account of itself and the greater efficiency of Class AB obviously makes it much more affordable.
The IOTA’s performance with the AVR850 is interesting because it raises the possibility of matching the amp with Arcam’s more affordable AVR390. This includes exactly the same processing, features, and Dirac Live room EQ as the more expensive AVR850, but lacks the Class G grunt. The addition of the IOTA would likely raise the performance of the AVR390 to new heights, resulting in a tasty combo for just over three grand.”
