Two issues when new at delivery. I had an overly amount of tube hiss. Much more than normal, even with my high gain amp. One channel was worse than others. I switched channels for tubes, never went away. Plus, the LCD would do this "blinking" thing every now and then. I called Rogue, they said just send it in. They returned the amp working perfect (hiss was now normal for my set up). I’m not certain they replaced the tubes or not. They said they replaced some op amps and the LCD display. No issues at all since. When I say built like a tank, I am referring to the "fit and finish" of the actual component, however, not one "electronic" or performance issue since.
I have since decided to go with a BHK preamp. I was looking for a while going RP-7, Direct Dac (Mytek) or Benchmark LA4. I am wanting balanced connections for a future amp purchase. I really like the fact that the BHK has a "standby" mode where you leave the unit on all the time, however, only the solid state side of things stay on when you press the button. The tube section goes to sleep (to preserve tube life). I had a PM from somebody familiar with both the Rogue and the BHK, the BHK is a major upgrade in sound and smoothness.
