Stick with the FET 10. Just because something is new doesn't guarantee that you will like it better. A good case in point is the 65 year old Quad 57. Many Audiophiles and speaker manufactures still consider it the Holy Grail in speakers!
Keep Vintage or sell for new
Currently have a Threshold FET 10_HL preamp which I love but wondering if there is something better out there
Have been considering:
PS Audio BHK preamp or Pass Labs XP12
Should I just sit tight with my Threshold or move to one of the two I mentioned?
For me the replacements I'm considering represent a good chunk of change and sorta hoping any responses will tell me to stick with what I have.
Thanks to anyone who takes the time to weigh in.
