I was pondering this same sort of situation. (Read the thread on timeless amp question in this forum) My Amp and preamp 20 years ago were around $25K MSRP. So as you, I wondered if there had been advancements to encourage me to replace them or bring them up to the most recent version from the factory. After reading the overwhelming comments on the topic I will remain on course and be sending them in to VAC for the Mk III upgrade. They just still sound wonderful to me and i know they are well built because they still work perfectly after 20 years! VAC is a small operation and known for quality components, I also like the fact the Kevin Hayes listens to everything before it leaves their doors to ensure it is voiced as intended, this includes any upgraded components as well. You may as well consider sending your pre amp out to Threshold and see if they can go over it and bring it back to new? They have an update/upgrade program on their website. This audiophile nirvana can get the best of us sometimes and cloud our better judgement. Good luck!
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.
