Which model "old" Adcom preamp do you have ? If you are willing to remain with Classé, you may find one of the models listed below with Bluebook prices a good match. The Phase LInear 3000 Series 2 is also an excellent sounding preamp I have had in my collection of vintage gear, and will recommend. The image below is my own, submitted to the site HiFi Engine.
DR-5 / Model 5 - $627 / $636
DR/6 / Model 6 - $1,030 / $999
CP-45 - $749
