for the price of these tubes they offered a more tube sound than the new JJ Tesla 6SN7 tubes I was using.  More musical, more dimension, a nicer more relaxed sound in direct comparison in the preamp.  Have not tried them in my hybrid tube power amp yet or to the many 6SN7 tubes I already own.
I enjoyed reading all of the comments and comparisons.  Since I build a 6SN7 based preamp, I had to find a current production tube with the preamps and amplifiers as I could not offer them with NOS tubes of which I own most of them already.

We built a preamp with a resistor selector switch to enable the user to switch between resistors any time.  This was more effective and made a bigger impact than changing the tubes.  Think naked Vishay, Caddock, Audio Note, Shinkoh, etc.  It was also an easy way to adjust the sound for the different recordings.  Then we changed the voltage for the 6SN7 tube we finally decided on and designed the products around that tubes sonic signature to our liking for the products.

That solved the problem of which tube sounds best on what recording, the cost of purchasing NOS tubes, and made the design easier to implement.

Happy Listening. 
@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.
