In the past 2 months, Janine Elliot - ex BBC sound engineer and professional musician, who has the ability to play 25 instruments - 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.

The icOn is sleek and modern in appearance, wonderfully effective as a sophisticatedly customisable and upgradeable volume control and source switch, and so easy to use. This product epitomises the realisation of high performance at a sensible cost, and its creator has done this through creative thinking, passionate commitment to the experience of music, and appropriate and clever design and engineering. This has created outstanding value and a surprisingly affordable price through impassioned innovation."

It takes the transformer volume control (TVC) passive preamplifier to a new higher level by providing the listener with absolute control over the source and volume of the music.

Unlike other passive preamplifiers, it uses a sophisticated digital interface to enable the listener to select the music of their choice from the convenience of the arm-chair and adjust the volume for maximum enjoyment.

What's more it's totally transparent,
unobtrusive and is competitively priced.
You will forget it's there as it has no musical signature of its own.

Client's Feedback

Hi Pal,
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.
