I’m currently in the process of building a new home, which will include the listening room of my dreams—I’ll update this information in a few months when we’re in!
The Zu Audio Omens are running full-range (no internal crossovers!), powered by the Emotiva XPA-1Ls, running in pure Class A and in balanced mode, controlled by the Luminous Audio Axiom balanced passive pre (Caddock resistors). The Zu’s are about 6 feet from the rear wall, and about 18 inches from the side walls, slightly toed in towards the sweet spot. Two subs are employed; the small REL T1 is connected directly to the mono amps via it’s 25 foot Speak-on cable and placed beside the listening position, with the low frequency cutoff at around 80 Hz. The 15 inch Definitive Technology sub is placed in the front left corner and runs full-output down to 25 Hz, and is controlled by the Acurus preamp.
With digital sources, the PS Audio NuWave DSD has both balanced and single ended outputs active, and they supply the signal to both mains and subs. With analog sources, the Acurus pre controls everything, and has two sets of single-ended outputs, and that’s also adequate to drive everything. The advantage to this dual-sub, dual-preamp setup is that everything runs full range, and there are no crossovers employed (except the internal LF cutoffs in the subs), and the Acurus pre gives you infinite control of the Def Tech sub to tailor the bass to your liking. Tons of LPs and CDs (and downloads, for that matter) are somewhat bass deficient; cranking the bass volume a few ticks can give an album (like Black Sabbath’s Paranoid) the requisite oomph needed to seriously jam! And I’ve been converting everything to DSD (2X) via JRiver Media Center 21—the results have been pretty freakin’ spectacular, giving digital files the kind of analogish sound I never thought possible for so few bucks (relatively speaking!).
The Omens are Zu’s entry level speaker, and the Dirty Weekend edition I own use repurposed drivers. My particular set (all three speakers) contain traded-in drivers from an earlier incarnation of the Zu Druid. The Druids were until recently Zu’s flagship model, with a MSRP of around $4,500, if that gives you any idea of the quality of the drivers in these speakers! The Omens are capable of very high SPLs, and when mated with the proper amp, these babies can really sing. They cast a ridiculously believable soundstage that is not only deep, but often extends far beyond the witdth of the speakers and sidewalls. They’ve never run out of gas at any volume level—if I hear any spurious noises in my room during full-output passages, it’s because the structure isn’t up to the demands of the Omens. Because everything runs essentially full-range, the sound is very clean, clear and detailed, but with a very liquid midrange at the same time. The Heil AMT Supertweeters add a significant amount of sparkle to the upper treble that’s particularly noticeable with female vocals, cymbals and delicate percussion. The crossover to the AMT’s consists of a 1.0 mf Audyn Plus capacitor with a 10-ohm Mills resistor following, and they’re simply cabled to the Omen’s inputs, so everything remains full-range. Metal, large scale classical, jazz vocals — when properly set up and driven by the right electronics, these speakers can go toe-to-toe with some of the best out there! This is not an expensive system, comparatively, but it is without a doubt the most musically satisfying I’ve ever owned, and casts a shockingly holographic stereo image.
