I used to own a First Sound passive preamp years ago. IMO all of the First Sound preamps are very good!
Each step up in price sounds better than the previous.
First Sound Preamplifiers Impressions
I am considering the First Sound preamplifiers. There is very little press information about them in most part because it's a small artisan builder but I have a couple of audiophiles in my local area who have heard them and think highly of First Sound. Hoping to get additional data points, are there any owners/ex-owners who would be open to sharing your experiences with the First Sound active preamplifiers? (you are welcome to PM me as well). Thank you.
