Overview

Admired Performance and New Enhancements
Music lovers have long admired the VTL MB-450 Signature monoblock amplifier for outstanding performance at a fair value. The new Series III version of the long-standing MB-450 platform features a complete re-working of the entire signal path. Upgrades include a fully balanced differential input stage driving a differential phase splitter and a lower impedance push-pull output stage with a dramatically improved, fully balanced and enhanced interleaved and coupled output transformer. VTL’s innovative engineering brings the legendary sonic performance of the venerable 450 Signature platform to even greater heights.

Enhanced Sonic Benefits
The new MB-450 Signature monoblocks gain further sonic benefits with a shorter, faster and fully balanced negative feedback loop, with zero global negative feedback. The negative feedback loop completely eliminates ringing and requires no capacitor compensation to maintain critical phase integrity and information. The result is an amplifier that remains stable even under the most demanding loads.

Stable Performance Under All Conditions
Adjustable precision-regulated bias and screen supplies hold the output tube operating point constant even under AC and main power supply fluctuations, and stabilizes the critical power supplies yielding tonal stability and sonic integrity especially during complex, dynamic signal conditions.

User Adjustable Damping Factor Feedback Control
Another new feature is a user adjustable Damping Factor feedback control that allows the user to adjust the amplifier’s output impedance by varying the amount of negative feedback. Impedance can now be precisely set to suit the listener’s taste, and to improve control of the loudspeaker loads to deliver best performance.

Damping Factor Settings
The 4 possible settings are:

LOW – Lowest damping factor, good loudspeaker control, most natural sound.
MED – Better loudspeaker control, with some impact on sound quality.
HI – Best loudspeaker control, with a little more impact on sound quality, but on speakers that need the control the sonic improvement is clear.
MAX – Maximum damping factor, but sonic impact is noticeable.

Premium Components for Improved Sound
Finally, the amplifier has been substantially re-voiced with premium Mundorf silver oil capacitors, for a sweeter, more extended top end and mid range tonality that sounds more relaxed, with better flow and integration. Input stage capacitors are also bypassed.

Superior Sonic Experience
Even a brief listen to the new MB-450 Series III monoblock reveals the successful implementation of the new technology. The mid bass has more authority and control while the critical midrange exhibits a new effortlessness in reflecting the natural instrumental colors and timbres. This greater sense of ease and control of the critical mid bass and midrange area enables the top end to sound completely natural and unconstrained. The impact of the music’s broad brushstrokes is unmistakable, while at the same time, the listener enjoys the indelible intimacy and micro-dynamics that lay deep inside favorite recordings.
