Tubes

@rooze  100% agree. I've been a huge NHT fan from the earlier days. 

Went with the pair of the gold lion12au7 and 12ax7 and Tung sol kt120 match quad set Whars my break in time on this set up?

@thirsty93 - I recommend reaching out to Brent Jesse for NOS tubes. Those Gold Lion tubes are not optimal. 

@bluethinker what do you base this on?  Do you have the same ST100 by Rouge?  Just wondering what you opinion is based on, fact, or innuendo? 

Those Gold Lion tubes are not optimal. 

I have two tube amps: Conrad Johnson and an Audio Hungary. The gold lions were stock tubes that came with the AH amp. Based on some recommendations, I went the route of NOS tubes. There was a clear sonic upgrade when I replaced the new gold lions. It’s an investment, but worth it in my book. 
 

Of course, it’s possible the Rogue is a completely different amp, but I’d bet NOS tubes would bring an improvement.
