"The finalization of your Pro was much slower than expected. Your 5-page intro generated so many leads, curiosity and even a few orders that I spent several hours each day with audiophiles from all over the world."

Still, exactly as promised weeks earlier, Pál emailed me on the 15th to request an address. My 3-in/2-out review sample was ready to ship. Born with the typical Teutonic birth defect of punctuality which expects it in others as well, I had to salute such sorted business conduct.

I bet many mail-order audiophiles will feel the same regardless of where they live. Online so much can be smoke and mirrors. Word kept is a currency of confidence. How many times do manufacturers fail to do what or when they say they'll do it?

I lost track. But exceptions do stand out and Pál was one. A páladin not of páltriness but pálatability? Something obscure and old-timey like it.

Meanwhile a modern feature set includes a metallic touch sensor on the front panel whereupon a short finger tap switches inputs, a long tap mute/unmute, a short + long night-mode on/off, 2 x short sleep mode on/off, 3 x short display bright/dim, 2 x short + 1 x long low/hi encoder responsiveness.

The latter sets how fast or lazy a knob turn or remote ± prompt runs through any volume changes. It works like a modern computer mouse which can be set for twitchier or slower hand reactions. Gamers prefer top speed, aged eyes like it slower. Bull riders need eight seconds. Audiophiles?

For the full tour, refer to the icOn 4Pro manual here.

With the icOn4 Pro an à-la-carte proposition, what will fully loaded units look like? Since Pal hadn't actually built a big one yet, he submitted this photo of his prior icOn3. "The big chassis was a transition between icOn 2 and 4. Because the small chassis has insufficient space for more than one pair of standard XLR, I'll use this bigger case for icOn4 Pro models which are optioned out for more connectors. It'll be the same look and feel but with a 7-segment amber display instead of the TFT. Optionally I can use the same TFT if somebody wanted that."

"The connectors on the rear will be different but similar."

If one wanted to drive particularly long cables for example, one or more outputs can be actively buffered with an opamp set to gain = 1.
