VAC

 


 

It’s hard to get your head around the idea that an amplifier which sells for more than $22,000 is a bargain; but, in fact, when you consider what the VAC Phi 300.1 sounds like and that it is able to translate that sound to just about any speaker out there, regardless of efficiency or load, IT IS. Simply put, the VAC Phi 300.1 is the best sounding tube power amplifiers made under $40,000. Select two of them bridged into mono and you are hard pressed to find anything other than Zanden which will even give them a run for their money!

The VAC Phi™ 300.1 is an extremely potent amplifier with power, superb definition, and great control. Its eight beam power output tubes yield 300 watts in bridged mono mode or 150 watts/channel in stereo mode at the choice of the user. Front panel level controls may be engaged to aid in balancing bi-amplified systems. Both balanced XLR and single-ended RCA inputs are provided. Triode operation may be selected at the flick of a switch. The chassis is machined aluminum, with the tubes beautifully showcased behind 0.75" acrylic glass. Also included are standard 12 volt triggers.

 



 


 

The Phi 300.1 is based on vac's direct coupled input & driver circuit that results in the fastest, fullest, most detailed sound that they have ever achieved. You will be surprised by details in your recordings that you had never heard before. The ambience and retrieval of reverb and decay information is particularly surprising.

Using eight beam power output tubes and a low-mu octal driver, this amplifier possesses an uncanny ability to reveal every nuance in a recording, while preserve the emotion and feel necessary for a truly musical performance. In addition to finesse, it has great power, impact, control, and a low electrical noise floor. This remarkable overall character makes it suitable for use with speakers ranging from high efficiency to the most difficult and demanding.

 

 

Both single-ended and balanced (fully balanced amplifier mode) inputs are provided. The chassis is custom machined 0.25" aluminum welded into a solid unitary structure, finished in metallic black paint. The 1" thick aluminum front panel is finished in hand rubbed silver metallic lacquer, with bias meter and tube adjustors that make it easy to maintain and optimize. Output matching taps are provided for 2, 4, and 8 ohm speakers.

 

Statement 450
Monoblock Power Amplifier

 

 

We thought it would be impossible for any one including VAC to build a better amp than the PHI300.1 so of course they went ahead and did

enterTHE VAC Statement 450 monobloc.

The sound of the Statement 450 literally caused our jaws to drop. If the Phi 300 is one of the world's best amplifiers, then the Statement 450 is no less than the redefinition of the term "World Class". It is not a subtle improvement. It is a whole new world.

VAC President Kevin Hayes describes its sound as follows: "This is an absolutely startling jump in sound quality. The voices, images, and dynamics are as solid as a concrete wall, and there is an order of magnitude more detail being presented, which manifests not only in hi-fi terms, but in emotion and, for example, being able to picture the expressions that play across a singer's face. It's not a subtle difference, or even a moderate difference; it is a quantum jump."

VAC's "first principles" design approach led us to four critical factors in the design and voicing of the Statement 450: increased precision of control over the drive/output circuit; control over stray interactions within the amplifier;

Statement 450S
Dual Mono Power Amplifier

The 225-watt/channel Statement 450S is a reduced-scale application of all of the techniques, concepts, and parts developed for the larger Statement 450. It is appropriate for the highest quality systems where space is a consideration or where extreme power is not needed. The 125-pound audio chassis is floated via an energy decoupling tripod atop the 100 poundpower supply. Simply put, this heirloom quality instrument is second only to the Statement 450 monoblocks for reproducing music with the “breath of life” that is always our goal.

The VAC Phi Alpha 200 is the finest combination of value & sound VAC has ever offered, being a more affordable embodiment of the circuits & technologies used in their premier Phi 300.1.

Using four beam power output tubes and a low-mu octal driver, it possesses an uncanny ability to reveal every nuance in a recording, while preserving the emotion and feel necessary for a truly musical performance.

In addition, the phi 200 has great power, impact, and control. This remarkable overall character makes it suitable for use with highly efficient or highly demanding loudspeakers.

 Renaissance Mk III

Second only to the flagship Signature Preamplifier, the Renaissance Mk III has all of the performance and features needed in a top-class music system, including balanced inputs and output, home theater input, hand-wired Class A triode circuitry, remote control, external power supply, and optional MM/MC phono stage with variable loading. The dynamics, detail, and speed of this preamplifier bring music back to life most convincingly.

Electrical Design
The VAC Renaissance Mk III Preamplifier is a development of the preamplifier section from the highly regarded VAC Phi Beta Integrated amplifier and provides balanced and single-ended input and output capability. It is completely hand wired, and all switching is accomplished via high purity silver contact mechanical switches. The six active circuit elements are twin triode vacuum tubes, biased for Class A1 operation.

 


 


 
Signature Mk IIa
Preamplifier

No preamplifier in the world preserves and reproduces the emotion and vitality of music as well as the fully balanced, all-triode VAC Signature, with its unique design that maximizes the performances of the source component and power amplifier. The superb optional phono stage is electrically a stand-alone unit that just happens to share the chassis, yielding world-class results.

 

Construction
The internal parts are specified from the finest and most exotic materials, as extreme measures and the most careful “voicing” are required to reach this unequaled pinnacle of perfection. The liberal use of sound deadening material compliments the aluminum chassis, creating a solid mechanical foundation. The VAC logos are backlit with an elegant blue in normal operation, but display red when the mute is activated. These are set in the heirloom-quality sculpted 3/8” faceplate. The main unit features two large gold-plated knobs for gain and input.

Electrical Design
Through its principal outputs, the Signature Preamplifier contains no coupling capacitors whatsoever, so nothing hinders the purity and detail developed by the hand-wired direct-coupled Class A1 triode tubes. Additionally, no loop negative feedback is used; the output interface is completely stable and free from dynamic interactions with the load. In addition to five standard line inputs (four when phono is fitted), a fully balanced input is provided. Fully balanced outputs are present, as are dual standard RCA outputs.
