Speaker will be Lansche 4.1 with plasma tweeter.

Digital source will be Dave and HMS fed by ripped CD stored in ssd drive of Cocktail audio x30.


I will play

Eva Cassidy's 'Autumn Leaves"

"Trinity Sessionn " by Cowboy Junkies

For classical orchestra, "Trittico" directed by Fennel.

"Still harry after all these years" will be for fusion jazz.

Any more suggestion gentlemen and ladies.

Thomas,

I had to return two sets of the Melz 1578 tubes due to noise.  I could hear them at my listening position and my speakers are not very sensitive.  I did get one quiet pair and kept those.  I wanted to get another pair for when these wear out, but gave up.  The 6N8S from Ukraine are surprisingly good.

6N8S from Ukraine are also good tubes at excellent value under 100$ per pair.

But I enjoy full bass out of Melz 1578.

Some Melz 1578 has a problem with noise.

Anyone recognize this tube, and the top lettering - "...chen" ?

Thanks. It looks like they come from extra stock or liquidated Old Chen preamp stock. See https://www.hifi-amplifiers.com/en/oldchen-tube-amplifierslaochen-c-118/oldchen-c1-hiend-6h8ccv181se...  gd-parts link for the tube goes to AliExpress, where they show 1000 pairs,
