Synergistic Tubes

We ran into SinglePower Inc.'s Mikhail Rotenberg as he was sprinting down the hall to the Synergistic Research room. "Check these out," he said. "These are a 1932 Tung Argon 4327 and a 1943 722A (323), labeled Centennial, but manufactured by Western Electric."

Rotenberg has a warehouse full of NOS treasures like this he bought from a MilSpec supplier near West Point. A few minutes later, we saw them in action, but we could have never guessed what they were being used in.

This is the Synergistic Research/SinglePower Enigma power supply ($6000) for Synergistic's active shielded Tesla cables (interconnect $1200–3000 per 1m speaker cable: $5400/8' pair).

Synergistic's Ted Denney explained, "The TungAr sounds great with small intimate recordings; the Western Electric sounds fabulous with big, dynamic music."

Wait, you're telling us the the tube running the shield has an effect on the sound? "Yup," Denney said.

It did. Something's going on here, but we don't know what it is.
