Power amplifiers are core components of any high performance entertainment system. Their task is formidable – they must comfort- ably drive any of a wide variety of demanding speakers while preserving all the power and nuance of the source material. The ability to maintain sonic neutrality, while exercising brute force or finesse as appropriate, is an
attribute that has made Mark Levinson power amplifiers the standard in the industry for nearly 30 years
The power supply is the foundation that all of the audio circuitry is built upon. Both amps benefit from a massive, dedicated, independ- ent linear power supply. Our ongoing listening tests continue to confirm that abun- dant clean power is essential for high performance. Precise control of this power reserve is the task of the amplifier’s voltage gain and output stage circuitry. Mark Levinson amplifiers have always featured precision circuitry designed to fully exploit balanced signals. Rather than adding op-amp buffers, or simply duplicating circuitry for both halves of the balanced input signal as many other amplifiers do, Mark Levinson amplifiers feature an advanced, inherently balanced topology for greater efficiency, performance and sonic benefits. The No436 and No434 have power ratings of 350 and 125 watts into 8 Ohms, and 700 and 250 watts into 4 Ohms, respectively.
As with all Mark Levinson amplifiers, particu- lar attention is paid to the layout and circuitry connections. All circuit boards are laid out by our engineers rather than by a computer
