I changed a Tube and…


I liked it!
 Have a Rogue Audio Cronos mag lll bought it years ago as original Cronos Mag  sent it in last year for the upgrade to lll .  Never changed any of the original tubes .

The amp was lightly used due to my changing amps like regularly. Decided to stick with Cronos and and have really enjoyed it . 
Playing vinyl for the majority of time and seem satisfied with Triode mode .  Amp runs perfectly no noise at all but thought about all the threads regarding tube rolling  especially the center 12au7 . 
pulled out the stock JJ and found a Genalex  Gold Lion ECC82/B749 (12au7)  bought them 7-8 years ago .  
Put the GL into center position and was thinking “am I going to really hear a difference “???   Figured I listen to a few LPs and maybe I’d notice something different good or bad Maybe ? after all it’s just one tiny tube !

Well I was blown away !, 30 seconds in listening to “two of a mind “ Desmond /Muliligan  things just got a whole lot more musical 🎶. Hard to describe everything seemed improved , midrange was wow ! Soundstage was better , etc .

Went to another familiar favorite Grant Green “ Idle Moments “   Oh yes the magic is here too 

Is this even possible or am I under a placebo delusion  lol 

Now I’m really wondering what about the other 2  12au7’s  and even the 2 -12ax7’s

what else am I missing ?

I bought a pair of NOS 1957 ECC83 long plate Bugle Boy for my Pro-ject DS2 Tube Box. They cost more than the DS2. 
 

They were worth it. A dramatic difference.
