About adding  Super Tweeter  from Fyne Speakers

´´

I spent time over the course of a few weeks listening to both super tweeters moving from one to the other and once I settled on my favorite settings for each I let the music take where it or I wanted to go. And every time I removed them, running the F502S in stock form, my excitement level decreased. I missed the additional sense of air, resolution and refinement.

Bass heavy music also saw improvements down low with a sense of greater bass definition and clarity that seemed to affect music’s overall presentation. While the differences between the S-Trax and SuperTrax were subtle at best, as odd as it may seem the SuperTrax seemed to offer greater impact in the lower registers as compared to the S-Trax. ´´

The 300 b tube softens the signal especially on the leading edge in the treble 

I have had custom ones made by Radu Tarta , for rock not recommended 

for jazz ,voices yes. Zesto makes a very nice preamp for much less $$ .and uses 4 -9 pins type tubes 

and solid state many good ones Aesthetix Saturn is very good and uses smaller 4 9 pin type tubes .

I have purchased a pair of Rockport Cygnus that were demos.  They will come with factory 5 year warranty which is always a plus.  Will hopefully be shipping early next week.

Congrats!!!
