I use a JPS Labs Power AC on my Celeste 4150se, which was recommended to me by a tech at Sim. I found one on Audiogon for 225 and especially at that price it was a no brainer, although even at retail, I think the Power AC is a good buy for your Titan. I would check out the Tice power cord too. I also echo the chorus on this site for a dedicated AC line, especially for a beast like the Titan. When I plugged my amp to a shared AC line, there was a clear loss of dynamics and visceral impact. That's a shame with a Titan, because slam is a strong suit of any Sim amp. Another Sim tip is to take the manufacturer's advice and leave it on all the time. Not only does this help break-in, which is notoriously slow with Sim amps, but it really makes an audible difference in my system.
