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

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.
Thomas and big_greg,
I'm not enjoying my second pair of 1578's at all. It's taking a long time to burn-in; they don't have the bass extension and impact of my first pair which sounded great from the start. It's a shame one of them crapped out.
I have 35 hours on Melz #2 and pulled them out. I'll burn them in some other time. Early 1950s Tung Sol GTB are sounding better than the Melz.
Luckily my replacement 1578's arrived today.
