High End Karan Hifi Dual Mono Design Power Amp 450

Brand New Condition Karan Acoustics S450 Pure Class A Stereo Dual Mono Power Amplifier


The KA-S 450 is a true dual mono, fully balanced design requiring two separate power cords. Keeping the signal path as short as possible, the KA-S 450 sports gold plated circuit boards and twenty fairly exotic ultra fast Sanken RET output devices per channel with total current capability of 400 Amperes. The KA-S 450 uses four stages of voltage regulation and each channel uses a 1,500 VA low loss toroidal transformer with 188.000 mF of capacitance. What is pretty unique about the KA-S 450 is its unusually high damping factor- better than 10,000 into 8 Ohms, 20Hz-20kHz.

This spec goes a long way in accounting for the KA-S 450’s fantastic bass response and over all sense of composure. While the KA-S 450 does not double down its power rating as a big Krell may, its rated power output of 450/810/1,500W into 8/4/2 Ohms is pretty impressive and left no sense of strain on swelling or sudden shifts of high level dynamics. The KA-S 450 is an all Class A design employing no overall negative feedback.

As far as analog amplifiers go, no other amp I have heard balances such an array of virtues leaving so little to criticize. First off, the KA-S 450 is the most organic/least electronic sounding solid-state amp I have heard to date. This organic quality comes to the KA-S 450 honestly. There is little softening, smearing or homogenization to the sound to “simulate” natural realism. It is by way of resolution and a deep sense of silence that this wonder full quality comes to light. Purity of instrumental tone, vocals and ambient space are all extremely well resolved. Tube lovers looking for a powerhouse amp should look no further. It is here that the KA-S 450 really distances itself from the competition but remember, for me to really fall for this amp, it must go further to prove it’s metal.

The KA-S 450 is the kind of amplifier many will be very happy to live with deep into the future. Such power and finesse, it’s like finding peanut butter in your chocolate – a very tasty surprise. No bones about it, the Karan KA-S 450 is a truly special amplifier that should send shudders up and down the spines of manufacturers that may have become a little too comfortable with their successes of the past.

Mint condition and like new.

One of the most musical sounding solid-state amplifiers available today. The amp is in mint condition (no marks, no scratches)


Comes with WBT-0210 Cu Ms (NextGen) RCA connectors, top of the line WBT-0702.12

Signature platinum-plated speaker terminals.

Furutech mains connectors, fuses and Cardas internal wiring - all highest quality parts and materials.

It is DC coupled (no capacitors in signal paths), power rating is 450W/ch and is totally dual mono. Separate power cords, power switches, power transformers, the works. The only thing shared between the channels is the chassis.

This amp will easily drive any loudspeaker with utmost musical ease and dynamics. The amp comes with original wooden packaging. Can provide additional photos and videos if required.

Very well build with high quality standard and materials used.

This amp does not get hot or very warm like other regular Class A amps, totally a different level of engineering and technology by Karan Acoustics people. As they are always well known for.
