Though it sports a vacuum tube preamplifier section, with six 12AU7 tubes, and a solid-state Mosfet power section, don’t look for a pair of pre-out/power-in jacks on the rear panel. Herman van den Dungen, the man behind PrimaLuna, reveals that this hybrid integrated amplifier is designed with a twist. While other hybrid designs usually use a pair of tubes as buffer or driver stages to add a bit of warmth, the EVO 300 Floyd brings together a vacuum tube preamplifier and solid-state power amplifier on a single chassis. Many audiophiles have declared their piece of audio heaven mating a tube preamplifier with a solid-state power amplifier to get the airy delicacy that tubes produce and the extra bass control, dynamics, and current drive of a solid-state power amplifier. Hence tighter, more powerful bass response. (And the relative subsets within these categories.) More often than not, tube designs possess an edge when recovering microdynamic information in a recording, and similarly, solid-state amplifiers usually have more current reserve, a higher damping factor, and more control over a speaker’s woofer cone. Possibly one of the most significant discussions we as music lovers have when assembling an audio system is the merits of vacuum tube versus solid-state amplifiers. Different devices, different topologies all have a different sonic fingerprint. Measurement geeks that say they all sound the same be damned. Admiring all the different works of art from such a diverse pool of creativity made me think about amplifiers and how they all sound so different. Listening to PrimaLuna’s latest amplifier reminds me of the last time I visited the Louvre. The EVO 300/Floyd leaves the choices to you. Some offer onboard phonostages (A high-quality MM phono can be installed in your EVO 300 at the cost of $299, and it’s very good) others concentrate on a built-in DAC.

As we’ve had a lot of great integrateds here in the last two years, mainly in the $7,000 – $12,000 range, there is a lot of competition at this price. This $7,399 integrated amplifier makes a heck of a first impression. The MoFi SACD offers a large soundfield in all three dimensions, and Mann’s voice is front, center, large, and breathy. Aimee Mann’s “Humpty Dumpty” gets the evaluation off to a start, as it has on every other review I’ve written in the last 17 years. The dCS Vivaldi ONE has a high-quality variable output stage, making for a perfect front-end component to allow easy comparisons, as the EVO 400 is a power amplifier only. The new PrimaLuna EVO 300/Floyd integrated amplifier begins its journey here with a PrimaLuna EVO 400 power amplifier (loaded with KT150 tubes) beside it on the rack.
