@shking78 thanks  interesting read  I hae never tried that particular tube.  I have always found the Tung-Sol black glass round plates to be the most musical and magical.  I will have to try the 1578 Melz myself just for the fun.  I also found the CBS short bottles to be a bargain basement for the price.I used to love the tube rolling game and enjoyed having friends come over to listen or bring a tube to their house for a listen.  I also recently used the Tung-Sol 6SL7 in a buddies Dude preamp with excellent results - slightly more gain but retains the TS magic and mid-range sweetness.

Happy Listening.

I received my replacement set of 1578 tubes today and they sound fantastic. No crackling like I had with the bad one I received the first time. My air conditioning has been on so I don't have a good sense yet of how low the noise floor is with them, but they are a little bit more noisy than other tubes I've used. So far the sound is wonderful with music playing.

My pair of 1980 Melz 1578 from Olga arrived yesterday. After playing 8-10 hours background music in our living room system I sat down to listen.
WOW!
I'm ordering another set of Metz 1578 now. I also ordered a pair of 1954 Metz 6N8S. 
What I noticed…. depth, focus and groove. I'm not a huge Kraftwork fan but listening to Tour De France (2009) remaster (M) Tidal I was unable to surf the internet the music kept drawing me in!
Thanks for the heads up Thomas

@mid40sguy 

It is very nice for you to enjoy 1578 tube made in 80's, 

I was skeptical of the tube when some person raved about it.

But after trying it in my amp, I became a believer.

@big_greg


It is good for you to get new replacement tube.

I hope that they will work fine.

Thomas, the replacement tubes are much better.  They are a little more noisy than other tubes I've tried but they do great things with the music.  It seems to have more weight and texture.
