Smart magnetic passive preamplifier - like no other

Probably the most advanced
TVC/AVC preamp available.

Join the revolution!

 takes the transformer volume control (TVC) passive preamplifier to a new higher level.

icOn is smart and unique. Unlike other passive preamplifiers, it uses a sophisticated microprocessor and digital interface to enable the listener to remotely control your music for maximum enjoyment from the convenience of the armchair.

There is simply no need to jump up from your chair to make adjustments at all!

What's more, it's totally transparent, unobtrusive and is competitively priced. You will forget it's there as it has no sonic signature of its own to add or subtract anything from the music.

icOn is a real game changer in the quest for listening to music as intended by the artiste!

Why icOn?

10 reasons

that will convince you to seriously consider icOn

one

Crystal clear sound

Crystal clear organic sound without any noise and colouration.

  • icOn uses a pair of bespoke, high-grade Supermalloy core transformers from one of the World's leading manufacturers - SAC Thailand
  • the use of reed relays offers higher reliability and noise-free switching than rotary switches as used in most other passives
  • short internal wiring  - no "rat's nest" in the signal path here!
two

State of the art design with premium features

icon_tvcpreamp_inside

icOn uses high tech microprocessor control. The firmware enables not only the basic features like balance and instant mute (which are missing from other TVC preamps) but also really high end features too, like automatic input level matching.

Volume level switching is carried out using high quality, hermetically sealed reed relays which eliminates the possibility of contact errors that can happen with conventional open rotary switches as used on many other passive attenuators.

Full remote control

All functions such as volume, balance, mute (-20 dB dim & full mute), source selection, sleep and night mode are controlled remotely with an Apple remote. Gone is the old school, noisy stepper motor solution as used by some other manufacturers.

Highest quality volume control possible

icon-features

icOn uses the best quality, most reliable input switching and volume control technology possible: the hermetically sealed miniature reed relay which has a switching reliability factor several thousand times greater than the outdated mechanical rotary switches or electromechanical relays.

The distance between the relay switches and the transformers, I/O connectors are very short - an inch or less only. We don't use tens of metres of hook-up wires. Less wire results in a cleaner, more natural sound!

Ultimate technical specification
- ahead of the competition

Dazzling parameters!

  • 1 dB volume steps
  • 66 volume levels at icOn AVC, 45 levels at icOn2 TVC
  • smooth control (1dB steps) even at the lowest volumes, where most of our competitors offer only 3-6 dB steps
  • vanishingly low distortion: 0,0001%
  • 0.05 dB channel mismatch
  • 10 dB balance range
  • broad dynamic range from -55dB to +10 dB in icOn AVC, -48 dB to +1 dB in icOn 2

You are in control! TFT display, advanced menu

iconscreen

A TFT screen (which can be programmed to be visible in a choice of different colours & brightness) means you can see exactly what you are doing from the comfort of your armchair, all operated via an Apple remote control.

With the new menu system of icOn, you can fully customize practically any parameters e.g. input alias, automatic input level matching, starting and maximum volumes, AVPassthrough, display & feedback lights' brightness, night mode, etc. to ensure a smooth, no-fuss music enjoyment.

The power of reed relays

icOn relaysJPG

Have you realised, that most passive magnetic preamplifier looks the same... TWO knobs and nothing more?

icOn only has ONE knob for a rotary encoder, that gives instructions to the microprocessor (along with the Apple remote) on what to do. We don't use old school, limited life expectancy rotary switches, only professional, very long life reed relays.

The best quality rotary switches have 25k switching cycle lifetime, till reed relays have 1 BILLION! switchings. In average an icOn has 70 pcs reed relays and within 1 sec 4 switching can happen...Do the math and you will see, that you have to push continuously the volume button of the remote... 24/7 for 555 years to reach the end of life of icOn's reed relays. That's what we call reliable and bulletproof!

As seen in:

Janine Elliot - ex BBC sound engineer and professional musician compared our icOn TVC preamplifier to her 4 times more expensive, "world's best" preamp listening to her own compositions. We can't imagine a more authentic reviewer.

Her conclusion was: "...this is an exceptionally well thought out and clever unit for those wanting the clarity and purity of passive but with additional features turning the technology truly into the 21st century... In terms of features and originality, it is in many ways an outstanding product and well worthy of your attention."

"Occasionally I find a product that instantly raises the joy level from my audio system - this is one. For several weeks the icOn had substituted for my own reference system Sachem Pure preamplifier (which provides less control) and had been a highly satisfying stand-in, yet at roughly a third of the cost. I had witnessed music playback with a consistently lively presentation, and the sense that nothing was standing in the way of the music. Yet I had very convenient control and support for my Sachem monoblock power amplifiers in doing their job highly effectively."

What others said about icOn

In the past, I’ve had some very high end preamps from Mark Levinson, Rowland, Coda, and Classe that could not deliver the detail that a great passive unit like yours easily provides.

Vocals, guitars, piano, and brass all sound more vivid and real with extra detail and clarity. Music is full and exceedingly dynamic.

The Icon is a very fine product and I hope you sell many of them.

Well received the icon today and setup into my system. Thanks for putting my name into the unit, it looks so unique. I tried many CD today using TVC mode and sound similar to my Django, with improvement on both clarity and bass.

Hello Pal,

Just a quick update on the preamp. Results of listening tests with classical and popular music are excellent! The amp is performing superbly bring out the smallest details of my recordings.
