One of the biggest revelations came when, during another listening session, I moved back and forth between the darTZeel NHB-18NS preamp and the Stromtank battery-powered D’Agostino Momentum HD preamp. I had previously declared the battery-powered darTZeel the most detailed and revealing preamp I’d ever heard in my system. With colors more direct and primary than the D’Agostino’s softer, more pastel-rich palette, and a soundstage neither as wide nor as far set back, the darTZeel seemed a champion of directness. With Stromtank battery power, the D’Agostino’s ability to convey detail increased to darTZeel levels, and its soundstage magic increased. I’d expected the Stromtank S 1000 to improve the sound of my system, but I never thought it would serve as the missing link to component greatness.

Oh, hell yes! It’s little wonder the EVO3 Aquarius proves popular with the Naim fraternity, because it has really good musical timing (more accurately, it gets out of the way enough to let the system play good timing), but the V5 Aquarius makes the EVO3 sound like it’s on strong antipsychotics. OK, so there’s no drooling or slurred speech involved, but where the EVO3 delivers good rhythm, the V5 is peppy, immediate and upbeat. It simply leaves the EVO3 behind. Given the EVO3 is already considered one of the most fast reacting power conditioners, and that the V5 leaves it almost for dead, this new chassis (and what it contains inside) is something of a revelation.

And the V5 reveals itself when playing some swampy country rock, such as Larry Jon Wilson’s ‘Ohoopie River Bottomland’ [Heartworn Highways, Light In The Attic]. This is a great and mostly unsullied recording, with an infectious beat but one that’s prone to getting lost in the ensemble. Any sense of reticence on the part of the power conditioner makes this track sound almost tired in the middle eight (the key change is so relaxed, you barely notice it until after it happens). Here, everything is just perfectly balanced and pitched. The EVO3 reacts fast to this kind of music, faster than many in fact, but the V5 just reacts faster.
