icOn passive preamplifier is
- a passive magnetic preamplifier (AVC) built around Dave Slagle’s world-class autoformers
- without colouration, noise or distortion, but has unrivalled transparency enabling you to enjoy the original recording to the full
- fully controllable from your listening position with an easy to use Apple remote
- capable of unlimited life of noise-free switching on account of using FET switches instead of rotary switches or reed relays
- adjustable in 1 dB volume steps, which allows a smooth control of volume having a range of 75 dB with 68 steps
- unbalanced and “true” balanced (with 2 pair autoformers) models with flexible input/output configurations
- highly functional with balance, mute, optional AV bypass, display with night mode providing control at your fingertips
- the most versatile and future-proof passive preamp family on the market with customizable features through firmware upgrades
- contemporary design with clean, sleek lines in a minimalist enclosure with high WAF
- highly innovative with unique features seldom found in passive preamplifiers regardless of price
- designed and built in the UK

People don’t just buy what they need. They buy what they want. which needn’t be the same. Case in point? Active preamps. Most modern digital sources will drive most modern amplifiers to full output. No extra gain is required, just signal cut/attenuation plus sure selection. What do active preamps do in this context? Look at it this way. 2+8 -9=1. Two is your source signal voltage. One is the signal strength needed to play at your desired loudness. Adding more gain symbolized by eight only to knock it down by nine is wasteful. A passive simplifies the math. 2-1=1. It’s pure signal cut, no boost. At the very least it’s more efficient so greener. It also should incur fewer losses from less signal manipulation and produce less noise and distortion.



How does it work?


Furthermore by the use of these FET switches the signal path is kept remarkably short, thus reducing possible interference to a minimum. This compares to the more common rats nest found in many TVC/AVC passives which can be prone to interference pickup.
Most people find that the autoformer volume control sounds significantly better than even the best potentiometer or stepped attenuator. And it’s not a subtle difference; most people report that the autoformer has such an open, effortless sound that they would not consider going back to a resistive device.
Most frequently asked questions
How long does it take to burn in my new icOn preamp?
If you ask me about the icOn’s burn (break) in time I would say: that for my icOn preamps there is no burn-in time. The copper wire and magnetic cores don’t change in short term (within a few years). But a lot of icOn customers stated that they have experienced improvement after approx. 100 hours of music listening. My understanding and experience are that this improvement happens in the listener’s brain and not inside the preamp. The autoformers produce quite a different sound than the resistive passive attenuators or active preamps. Our brain “learns” this new sound experience, and adapts to the complete lack of background noise and distortion, the higher transparency. Some audiophile calls this adaptation as the “burn-in”. I’m an engineer and music lover too but like to stick with the scientific and engineering facts. Maybe I’m wrong with the science, who knows? So as usually – YMMV … your mileage may vary 🙂
I did read a review where a different wall wart was used with the icOn and there was a slight improvement despite the passive sound path. Can I make my icOn even better with a LPS (linear power supply)?
