The VAC Renaissance Seventy/Seventy has been developed with the critical ear as the major arbiter of quality, with both conventional and unique measurements providing insight and guidance as necessary.

The lack of emphasis on measurements is due to the fact that engineering's arsenal of equipment and techniques do not operate on the pattern recognition principals that control human perception of sound. In the immortal words of Daniel von Recklinghausen, if it measures good and sounds bad it is bad. If it measures bad and sounds good you've measured the wrong things.

For those concerned with test bench performance,the following describes typical measured performance when operated with no feedback (0 dB) at 120 VAC, 60 Hz. Power Output: 65 watts continuous average power at 1 kHz with less than 2% THD into 4 ohms connected to the 4-8 ohm tap. Distortion: 0.12 % THD at 10 watts. Frequency Response: down 0.5 dB at 6 Hz and 90 kHz, ref 0 dB = 1 watt @ 1 kHz. down 3.0 dB at 2 Hz and 103 kHz, ref 0 dB = 1 watt @ 1 kHz. Power Bandwidth: down 0.5 dB at 12 Hz and 58 kHz. down 3.0 dB at 8 Hz and 85 kHz. Negative Feedback: Selectable: 0, 3.5, 4.5, 5.5, 6.5, 7.5 dB. Absolute Polarity: Does not invert absolute phase.
