Tubes

@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. 

My AH came with KT170's... 

@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.

I have had many rogue mono blocks, I have found a Winner combo Mullard

4003/4004 sweet brings out the best  in these amps.

the Apollos have those in. before that the 120's

Good listening
