A sonic revelation with a separate power supply and NOS RCA tubes.
The PA-01 preamp uses a solid state rectification, no choke and a complete regulation of all voltages with tubes. The way though is completely without any components except the output capacitors by Mundorf.
This preamp is very dynamic and loves details. Instead of a potentiometer, a attenuator with Vishay resistors and motor remote control is used. Also implemented is an excellent MC phono stage with Lundahl transformers that uses the 4 tubes on the right.
Jack Roberts, Dagogo.com, T.H.E. Show Newport Beach June 2016:
"...the sound was as good or better than anything at the show at any price. I love single-driver speakers and even with the bass extender, the sound was that of one of the best single-driver speakers I have ever heard. Again, let me say this was easily one of the very best sounds of the show. In price, it’s not quite a mega-system, but in sound it surely was!"
Jonathan Valin, The Absolute Sound, T.H.E. Show Newport June 2016:
"...my third best sound of Newport Beach was Holger Adler’s $34.9k Voxativ 9.87 one-way (using Voxativ’s AC-4x spruce-wood-cone driver with neodymium magnet and whizzer tweeter in a folded-horn enclosure, which sits atop an active 12" dipole bass “extender”). Driven by Voxativ’s 845 SET monoblock amps and Ampeggio preamp, and sourced by Totaldac digital, this German masterpiece couldn’t be more different than Cessaro’s horns or Gauder’s steeply crossed-over multiways (both also from Germany, as it turns out), but its sound was, in its own way, just as fascinating and just as realistic. Neutral and absolutely seamless, the 9.87 (along with Voxativ’s Ampeggio Due) is simply the fullest-range, most natural-sounding one-way (or augmented one-way) I’ve ever heard. And once you’ve heard a speaker without a crossover that is this good, it makes everything else sound just the slightest bit cobbled together from parts. No, you’re not going to get the dynamic range of a horn speaker from the 9.87, nor quite the same resolution or treble extension that you get from the Gauder, but what you are going to get is true point-source imaging and a sound that doesn’t change a jot in timbre from octave to octave..."
Jason Victor Serinus, Stereophile, RMAF Oct. 2015:
"...Voxativ may be one of the only companies in the high-end whose equipment list is designed as a flow chart. The visual presentation seems entirely apt, given how beautifully music flowed through the eye-catching and soul-pleasing Voxativ 9.87 system loudspeakers with its AC-4d wideband driver and bass extension ($34,900/pair)...
...this truly superior system excelled in communicating the life and beating heart behind the notes. Listening to Agnes Obel via Tidal, I heard beautiful sonorities distinguished by open highs, a superb midrange, and deep bass. Nor did the voice of Cassandra Wilson on "Strange Fruit" possess anything other than a special and wondrous beauty. Switching to analog, a fabulous recording of the Tsuyoshi Yamamoto Trio's Live at the Misty excelled in its percussive impact. I wouldn't call this system totally neutral—it had a special shine to it, as would a jewel that had been buffed and polished to perfection—but it was supremely musical and drop-dead seductive..."
