...is now $196 off--that is, $499 instead of $695--at The Cable Company. https://www.thecableco.com/adept-response-ar2p.html
I am merely a customer, and a new one at that, of TCC.
A few years ago, I used one of these (in the Teflon-cap version) to feed my 650-Watts-into-8 McCormack DNA-750 poweramps. One thing I loved about it was its magnetic-circuitbreaker/on-off switch, which I used to turn on the two huge poweramps that drew LOTS of current, especially at turn-on. I'd turn on the aR2p, the breaker would open in about a quarter-second, I'd turn in on again and it'd open, and finally with the amps' powersupply caps maybe 2/3 charged, the breaker would stay on after the 3rd attempt. I thought using the PCon's switch/breaker was 'kinder' to the amps' on-off switches than using those switches. Sold all that a couple years ago, but I'm now trying to buy the very same DNA-750 pair that I sold to a friend a couple years ago, so I bought another aR2p.
The Trippe-Lite isolation-transformer PCon and the PS Audio 'wall-wart'-type filter in the pic are long gone.
