See where the icOn is used

After a month of owning the icOn 4 Pro, I must say that I like it very much. It has no (or perhaps very very little) signature of its own. The significant more volume steps and the ease of use brings also happiness. I did have many preamps over the last 50 years but this jewel beats them all…

It sounds wonderful

Hello Pal,

I’m happy to report that the Icon arrived safe and sound and that I’m very pleased with the quality of build and appearance. Shipping was very fast and well worth the price. I listened to it for a couple of hours yesterday and today and it sounds wonderful.

It is noticeably clearer in the mid-range than the passive unit I’ve been using for the past few weeks. The highs and bass seem about the same as the Adcom which is quite good, but the mid-range is definitely more prominent and clear. Overall, the sound quality is at a higher level. At this point, I believe it will be impossible to return to an active preamp no matter how high the quality or cost.

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.

Overall, I am very impressed with your product and the level of communication is outstanding. I’m looking forward to many years of trouble free service from the Icon and great sound too.

I wish you continued success and a bright future with your products.

Very sincerely,

The amp is performing superbly

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.

Very nice wide open detailed soundstage

Dear Pal,

Just wanted to let you know that I’m very happy with the preamp.

At first glance it sounded almost the same as my 300B preamp, but without
the noise and hum. Later on, as the preamp got burned in, the sound opened
up and I got a very nice wide open detailed soundstage. After that, the
bass got very quick and tight, much better than the 300b amp did.

The preamp also sounds really nice on a low level. With the 300b amp I
sometimes found myself with peeping ears because I played too loud in order
to get a ‘live sounding’ sound.

The ultra low noise of the preamp is a big plus. The noise level coming
out the horn speakers is very acceptable.

Best Regards,


Improvement on both clarity and bass

Improvement on both clarity and bass

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.

Very refined.

Daarna begon hij te zingen en wel in het hoog wat ik omschrijf als ; zijdezacht, niet Upfront. Het laag kwam wat later en wel wat men niet zozeer zou verwachten van een buizentrap maar meer van een torrenbak.
Laag is niet “zwabberig”maar strak en is weg als het weg moet zijn.
Stemmen zijn altijd met kippenvel aanwezig, blijf hier elke dag van genieten.
Wat mij ook is opgevallen dat in de stemmen totaal geen geforceerdheid aanwezig is. Bij de hoge vrouwenstemmen blijft de stem overeind, zijdezacht.
De Icon geeft je ook een kijk in de instrumenten. Het volume is zeer aangenaam, of comfortabel zoals u wilt, in bediening. Zeer verfijnd.
Voldoende inputs en outputs voor mij.
