Smokes...now that is 'playing with power'...stunning system. I have heard the all-Tidal system at Audio Exotics in Hong kong...i have actually heard 2 of their systems. I was extremely impressed with the Stahl-Tek Vekian (prefer my Zanden)...but i have heard the Stahl-Tek Opus is another league from Albert Porter who recently posted his thoughts here. Now that is intriguing! Please tell us...how does it compare to Stahl-Tek Vekian? If you have listened to Zanden, pls compare as i know that digital best. (Though i have heard Scarlatti and auditioned quite seriously...respected but did not love.)
