Movies and Music
I set up the PVA 7 in my reference music and theater system, utilizing the Sunfire Theater Grand II and the NAD T571 carousel DVD player that I will be reviewing next month. For main speakers, I used my new Revel Ultima Studios (a tough load at 86 dB efficient), the NHT SC1 center channel (86 dB), the NHT ST4’s for the left and right surround channels, the NHT SB3’s for the effects channels, and the Sub One I subwoofer to handle the lower octaves. After 30 or so hours of break-in, I was ready to go.
I started off with some two-channel source material to see how the PVA 7 handled music. First up was Creed’s latest effort, Weathered (Wind-up Entertainment). Scott Stapp’s vocals on the title track are given their due through the PVA 7, with his characteristic growling voice sounding nearly as good as I’ve heard through my reference $5,000 Bryston 7B-ST’s. The PVA’s demeanor is very musical.
Next I turned to one of my all-time favorite bands, Rush, and their re-mastered Power Windows (Mercury Records) for some idea of how well the PVA 7 would portray intricate and technically challenging Canadian art rock. For good kick-drum, I used "Mystic Rhythms" to test the control of the PVA 7. The start of the tune is basically Neil Peart’s drums thumping the rhythm, which is then joined a by synthesizer. The PVA 7’s dynamic presentation of the kick-drum was pleasantly surprising in its ability to delineate the striking of the pedal against the drumhead and the clash of the cymbals with good control. Guitarist Alex Lifson’s single-string picking technique was rendered with a nice leading edge that gave it the crisp presence that I’m used to hearing with my Bryston 7B-ST’s. The 500-watt Brystons do give this part of the tune more snap, and deservedly so, considering that the 7B-ST is in a very different performance and price class. On "Marathon," the heavy synth bass is fleshed out nicely, as these bass notes test the power reserves of any amp. The PVA 7 did a very nice job exhibiting its ability to capture the low-frequency resonance with deftness not expected from this level of amplifier. In comparison to the recently reviewed B&K 307 receiver, the B&K 150 watt internal amp did have a slight edge in the slam department, but the PVA 7 wins the refined presentation category.
For a midrange test, I turned to Willy Porter's Falling Forward (Six Degrees Records). The tune "Hard" has a warm bass line that is sustained and resonant throughout this ballad. The quietness of the PVA 7 is readily apparent on some of the quieter passages in this tune, which brings out more of the lower level detail than I’ve heard on the B&K 307.
For movies, I turned to Star Wars: Episode I -- The Phantom Menace (20th Century Fox Home Entertainment) to test the EX capability of the PVA 7 on the atomic pod race scene. If ever there was an amplifier test DVD, this is it. The dynamics of this soundtrack will tax a component's performance to the limits. At loud volumes, the PVA 7 could run out of headroom at times with the demanding Revel and NHT speaker system. When listening to the pulsing low-frequency noise of Sebulba’s pod racer, The PVA 7 came up a little short in its ability to render the low-level detail I’ve heard when running my reference Bryston 7B-ST’s. However, you have to remember that this amp is more about finesse that brute strength. The PVA 7 deftly handled the complex multi-channel assault given by the pod racers when played at reasonable levels (albeit not at theatre volumes) that were loud enough to give you the desired impact. Explosions didn’t seem congested, muddied or compromised, except at higher volumes, when at times the PVA 7 lost some refinement in its presentation.
For subtle spatial cues, I turned to The Mummy Returns (Universal Pictures). In Chapter 2, Rick enters a tunnel, first tearing through a wall of spider webs, which the PVA 7 depicted nicely, then drawing and cocking his pistol, which reverberates and echoes convincingly, capturing the ambience and sense of space all around you. The resolution of the chapter was very detailed, truly revealing the PVA 7’s ultra-low noise floor by presenting some of these aspects of the soundtrack that weren’t as noticeable when played through the B&K AVR 307.
Disney’s Atlantis (Walt Disney Pictures) was a fun piece to hear though the PVA 7. The battle scene in which the revived machines from Atlantis are used to stop the marauders from making off with the Heart of Atlantis has them swirling through tunnels and in and out of caves, all seemingly dodging audibly around the viewer. The dexterity and articulation of the PVA 7 was very engaging.
When you consider the price point of the PVA 7, few would challenge anybody to find fault with this Sonic product. The only nit I would pick would be the back panel layout. The logic of the layout is seemingly dictated more to the convenience of the electrical layout than to making it easy to hook up your components and speaker connections. I had to have the manual handy to make sure that I was hooking the right interconnects to the corresponding speaker terminals. It is not a very intuitive layout.
The Anthem PVA 7 is a remarkable product. Its seven-channel capability, with its affordable price and quiet noise floor, gives you all of the tools necessary to handle any format. Although the PVA 7 did come up a little short with my Revel Studios, 86dB is a very tough load to drive. Matched with a more efficient speaker like a B&W, Energy, PSB or Paradigm, the PVA 7 will yield remarkable performance. The back panel layout is somewhat confusing, but not a glaring issue. The ability to complement any component with its velvety silence and poise under demanding conditions, along with its musicality, put it at the top of its peer group. The excellent reputation and build quality that the PVA 7 gives its owner is not to be ignored. And the PVA 7 will not limit your future of music and movie entertainment, handling two-channel music as well as Dolby Digital EX and DTS ES formats with poise and control. If you are in the market for a multi-channel power amplifier, this could be just what the doctor ordered.
