Pioneer VSX-934 AV receiver review

hcc_recommendedBy now I shouldn't be astonished by the lengthy spec lists of affordable AVRs, but this Pioneer still elicits a double-take. In bang-for-buck terms, the £440 VSX-934 seems irresistible.

A seven-channel model, it aims to please movie fans with Dolby Atmos and DTS:X support (and their associated upmixers) via 5.1.2 setups. Power is rated at an improbable 160W per channel, via a 6 ohm, single-channel measurement with 10% THD. You can expect that to drop considerably into 8 ohm loads with all channels driven and minimal distortion, which is probably why Pioneer doesn't quote such a figure.

The VSX-934 has tricks up its sleeve for music lovers, too. There's hi-res file playback over a network or the receiver's front and rear USB ports, plus streaming audio integration – TuneIn radio is joined by Tidal, Spotify, Deezer and Amazon Music support. Two of the AVR's channels can be used to feed a second stereo zone, or a line-level output sent to powered speakers. There's also an MM phono input for turntable owners.

Multiroom audio provision is a bit more controversial. 
As with last year's VSX-933 there's no unifying system in place here (such as Denon's HEOS 
or Yamaha's MusicCast). Supported standards instead 
are DTS Play-Fi, FlareConnect, Sonos and Apple AirPlay 2. For UK consumers, 
the latter two will probably be the most relevant.

Elsewhere this 2019 model also feels very much like 
a continuation of the Pioneer norm. Room EQ, for 
example, is still governed by Pioneer's proprietary MCACC system. On the VSX-934 MCACC is rather basic, but that probably won't bother end users. Higher-spec Pioneer receivers 
ship with MCACC Pro, which carries a greater level of adjustment, particularly when it comes to subwoofer optimisation. Here, the test tone process (accompanied 
by neat onscreen graphics) measures speaker distances, 
then sets levels, crossover and EQ. Of course, it's recommended you instigate it (it only supports one measurement position, so doesn't take long), and – this doesn't always happen with entry-level EQs – its speaker distance measurements were pleasingly accurate in 
my room. Yet, as with the VSX-933, the pre/post room optimisation differences weren't night and day. And I still felt the need to manually tweak subwoofer and Atmos speaker levels to get a preferred balance.

Styling is familiar too. The VSX-934 looks much like any previous Pioneer budget AVR, with its typical twin knobs-plus-central display approach. Then again, practically every receiver from any brand ploughs a similar furrow.

Connectivity is not as extensive as some of the competition. HDMI inputs are 'limited', as it were, to six, while Denon's AVR-X2600H (admittedly a bit more expensive) turns heads with eight. You'll probably only need four, though. All HDMI connections (there are also two outputs) support 4K HDR passthrough, including HDR and REC.2020 colour.


Pioneer's handset is a continuation of the redesigned zapper of last year, which thankfully put an end to the brand's history of overcomplicated handsets for budget receivers. The key tweak this year is a softening of its 
edges and buttonry. It feels a bit more contemporary.

Also contemporary is Pioneer's remote app, which 
paired instantaneously with the receiver and has a polished, uncluttered feel. Use this to access your streaming music subscriptions, but keep the remote close for simpler control when it's movie night. The AVR's onscreen menus, meanwhile, are also sharp and user-friendly, except the pop-up AV Adjust tool, which is painfully low-res and needs updating (and, yes, I made this point before...).

Pioneer VSX-934 performance
Pioneer terms its amplifier technology 'Direct Energy'. Confusingly, this term is also used for its Class D-based SC-LX901, SC-LX801 and SC-LX701 models, and the slimline VSX-S520D. Here, though, a more traditional 
Class AB design is employed.

Tech talk aside, the amplification lives up to its name, with an energetic delivery and a decent amount of power on tap. Connected to a Focal Sib Evo Dolby Atmos 5.1.2 package, I found the combination enjoyable.

John Wick: Chapter 3 – Parabellum (Ultra HD Blu-ray) gives the VSX-934 plenty to do. A lot of it involving guns. The receiver laps up the Atmos bullet bonanza, proving quick to act and able to steer effects with poise. As Wick and Sofia shoot every bad guy in Casablanca, I felt cocooned within the onscreen ultra-violence.

The AVR (after a firmware update that should have arrived by the time you read this) will offer Dolby's Atmos Height Virtualizer post-processing to, it's claimed, create 
a height effect without the need for dedicated overhead speakers. For buyers of sub-£500 AVRs, this might make sense, as there aren't many Atmos packages around that feel commensurate to the VSX-934's price tag.

Many, I suspect, will use this machine for traditional 5.1, so I removed the Focal's upfiring drivers from the equation. The DTS-HD MA 5.1 soundstage of The Town (Ultra HD Blu-ray) still felt immersive, MCACC effectively balancing the tough-guy dialogue with the Boston city ambience. When Doug (Ben Affleck) and Jem (Jeremy Renner) head out for some retribution ('We're gonna hurt some people'), the VSX-934 evokes the quiet tension in the scene.

Blade Runner 2049 (Sky Cinema) poses it a bit more 
of a problem, as Hans Zimmer's bass rich score and the strong LFE track did sound a bit overblown and unruly 
at times. It's as if Pioneer has tuned the receiver to be boisterous, which isn't necessarily a bad thing, but a 
more accomplished EQ system would likely result in 
a tighter performance.

More fun can be had from streamed music. Pioneer doesn't go in for a plethora of genre/venue-specific post-processing modes (the choices are Classical, Rock/Pop and Unplugged) but that's of no concern. The same full-steam-ahead approach it shows with film mixes is good for upbeat tracks and electronica, and the Extended Stereo and Extended Mono modes bring your other speakers into play without any enjoyment-robbing 
pseudo surround pretensions. Digital file playback includes 192kHz/24-bit ALAC, AIFF, FLAC and WAV – plus 5.6MHz DSD – but again I'm not sure if this receiver's target audience will lap up this functionality.

Pioneer VSX-934 verdict
So who might buy the VSX-934? Certainly not anyone who bought the VSX-933 or other budget model in the last year or so. But while this doesn't introduce anything really new), debut AVR shoppers or those kitting out a second room system should give it consideration. It's well featured, easy to use and punchy.
