Electrical engineer Vern Credille, 65, who spent more than three decades working alongside Wilson Audio founder Dave Wilson and, later in his career, Daryl Wilson, Dave's son and successor, died of cancer on Friday, June 12, 2026.

A statement posted to wilsonaudio.com makes clear the magnitude of the loss to Wilson and its community. "His influence can be found throughout many of Wilson Audio's most iconic products, from the X-1 Grand SLAMM to his final tweaks and touch on the Autobiography. Together with Wilson Audio's world-class R&D team, Vern's unwavering pursuit of truth…

I examined the SPL Performer s900's behavior on the test bench with my Audio Precision SYS2722 system. Before I started the testing, I removed the two transit bolts on the bottom panel then preconditioned the amplifier by operating it at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that time, the temperature of the perforated top panel was 139.6°F/58.9°C. This amplifier runs hot!

The Performer s900 has both balanced and single-ended inputs. I performed a full set of measurements at the balanced inputs, repeating some tests at the…
