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. 

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

@tkrtrb125 - I have the AH 100 power amp with KT150 tubes. I replaced the smaller tubes.
 

How do you like the KT170s? I’ve not had the opportunity to hear them.
