Product Description

Icon Audio Stereo 30SE is a medium powered single ended integrated valve amplifier with ultra-smooth warmth and colour.

100% Pure Class A

The ST30se offers absolute listening quality through simplicity of design and pure “Class A” operation. This is achieved by using a very simple design, high quality construction and our unique transformers designed and manufactured in house.

Because both the driver and output valves are drawing full power even at zero volume, the valves never “switch off” or go into a “low” state. This thermal and power stability enhances the reproduction of macro dynamics and sound stage spaciousness.

6SN7 Valves

Previously, affordable Single Ended designs have been low powered at around 9-13w. The excellent new KT150 valve enables more than double this power for the same cost.

The all-important high definition drive circuit for the KT150 output valve is achieved by using the superb 6SN7 valves in “Cascode” mode to get the best qualities of SE without the drawbacks of flabby bass, hum and low power that many designs suffer.

Triode Optimised

The ST30se is optimised for Triode as well as UL operation. 18 Watts being ample for most situations. Especially with our new “Full Range M” or MFV3 speakers and other designs such as the classic Tannoys, the ST30SE will work well with any speaker of about 90dB or more. Good sensitivity from the built in “passive” pre amp ensures good results from virtually any type of input.

Easy Bias Meter

The “easy bias” meter enables simple checking that the KT150 is at optimum performance, the meter also gives an indication of the output power. Very useful when you may need to know if you are likely approach the maximum available power.

Relaxed Sound

ST30SE is ideal for most situations where adequate Single Ended power is required by someone wanting a very relaxed sound and is well suited to larger more efficient speakers. It also features low power consumption, economical valve replacement cost and a low maintenance design.

Single Ended

Only one output valve is used so the one valve has to “push and pull” on its own. Although this limits the power available, the lack of “phase splitter” stage required by “push pull” amps means that the mid-range and upper frequencies have less “processing” which gives a smoothness and charm to the sound not found in other designs.
