A major benefit of the Duet is that it can deliver large amounts of current without restriction. For example, the Playback A/V lab uses a very powerful (and power hungry) Anthem Statement P5 multichannel amplifier designed to be fed by two wall circuits.
Accordingly, we use separate wall circuits, each feeding a Duet Power Center, to supply power for the Anthem amp—with excellent results.
For many home theater/music system owners, either the Duet or its bigger brother, the Quintet, will offer the best value for money of any of the PS Audio power conditioning products.
What it is: The Quintet is essentially a ten-receptacle, five-zone version of the Duet, but with added features including two 12V triggers, two coaxial (cable TV or antenna) protection ports, one phone line protection port, and power-on delay switches that control three of the Quintet’s five IsoZones (the delay options include Always On, Switched On, or Delayed On).
Benefits: Same as for the Duet, but with coax and phone line protection, 12V control switching, and power-on delay functions. In terms of flexibility and visible/audible benefits, the Quintet is perhaps the best bargain I’ve ever encountered in the world of power conditioning products (you can spend more, but few products actually do more than the Quintet).
What it is: More than a conventional power conditioner (though it is that, too), the Power Plant Premier is a groundbreaking product that not only prevents damage from spike and surges while filtering out noise, but actually re-generates AC power in a hyper-pure form. The Power Plant Premier offers all of the core features and functions of the Quintet Power Center while adding the following:
In short, the Power Plant Premier does everything the Duet/Quintet conditioners do and much more, with even greater visual and sonic benefits.
Practical benefits: Putting a Power Plant Premier in your system is like using a Quintet Power Center “on steroids,” in that whatever was quiet and pure before becomes even quieter and purer with the Premier in play. TVs, even ones that looked quite good beforehand, deliver noticeably better picture quality, with onscreen images that look cleaner, richer and have more visual “snap.” Audio components, even ones that sounded quite refined beforehand, deliver low-level textural and transient details with greater clarity and purity than before. Two particular sonic benefits of the Premier are more expressive dynamic contrasts in music and soundtracks, plus noticeably more powerful and better-controlled bass.
Caveat: The Power Plant Premier’s maximum power output is 1,500 watts as compared to 1,750 watts for the Duet/Quintet conditioners. In most systems this won’t matter at all, but for use with some very highpowered amps it means a Duet or Quintet would be the better choice.
Is the Power Plant Premier a good deal? In one sense it certainly is, since it does some good things no other conditioner can do, and it is undeniably a better performer than the already excellent Quintet.
On the other hand, the Premier costs more than four times as much as a Quintet ($1,700 more) without providing a proportionately large jump in observed performance. My thought: high-enders pursuing true top-tier performance will find the Premier a revelation that is worth what it costs and then some. Budget-minded enthusiasts, however, might find it more cost effective to buy the less costly Quintet and to spend the difference upgrading other system components.
