New preamp in system

I was using Linear tube audio MZ2 no remote. There was a clear out price on the Conrad johnson ET-3SE so I ordered a brand new one since I use to own a 17LS2 10 yrs ago. Right out of the box it sounds very similar to the broken in MZ2. I will see 500 hrs later if any more changes. Maybe MZ2 a smidgen fuller & airier. I was running brimar 12bh7s & Shuaguang cv181 black treasure in my MZ2. Moral of the story is don't believe everything you read online and reviews saying this is bright and harsh. I laugh at the reviewer from Home theater review. Btw I am using the Tungsram 7dj8 not the stock 6922eh in the cj. Good luck listening!😁
