VAC Standard Preamplifier LE

At its introduction in the summer of 1999, the Standard Preamplifier became VAC's hottest selling component. When the introduction of the ultra-high-end Renaissance Signature Preamplifier was still several months away, one of the world's most influential audio dealers felt the need for an "interim" flagship model, a preamplifier selling for under $5,000 but capable of blowing away anything under $10,000. Enter the "hot rod" Standard Preamplifier LE.

Basically, the Standard LE is the original Standard, but fitted with Renaissance-grade parts and remote control. It's the best thing going under five figures!

For multichannel systems users, there is also the VAC Standard 6.0 Preamplifier.

VAC Standard Preamplifier LE Specifications

• Type: Remote controlled Class A all Triode Vacuum Tube Preamplifier with separate power supply and Cinema (home theater) pass-through.

Options:

• Class A all Triode Vacuum Tube MM Phono stage
• MC Phono step-up (wideband transformer coupled)

Line stage preamplifier:

• Gain: 24 dB
• Maximum input signal: Infinite (attenuation precedes the gain circuitry)
• THD: Approx. .04%
• Output impedance: 350 ohms; main output inverts absolute phase from all sources
• Tape output: Unity gain from selector, non-inverting
• Cinema pass-through: Non-inverting, no gain, does not compromise the sound quality of normal stereo operation. May also be used for input of stereo source components with their own level controls (dacs, etc.).

MM Phono stage (option):

• Class A Triode Vacuum Tube
• Gain: 37 db (measured at tape output)
• Residual noise: 3 mv at output (S/N ratio approx. 69 db)
• Overload: 117 mv @ 1 kHz = 8 volts RMS output; 460 mv @ 10 kHz
• Frequency response: RIAA +/- .25 dB Notes:
• Does not invert absolute phase. This means the output at the tape jacks is non-inverted; the output through the line stage is inverted, just as with line level sources.

MC Step-up (option):

• Special ultra-wideband transformers
• 20 db gain
• works in conjunction with the MM Phono option.

Tube complement:

• 2 x 12AX7 low noise (MM phono option)
• 2 x 12AX7 (line stage)
• 2 x 12AU7/6189A (line stage)
