B&K EX 4420 vs B&K EX 4420 reference

Willland your first sentence nailed it and reflects my opinion as well,  well put.

@phd,

Thanks for the kind words.  I miss the EX4420.  It served we well and was a great trade for a Revel B15 subwoofer that has been rock solid.

Bill I have my B&K EX4420 hooked up to the Adcom GFP 565 preamp, you know the Stereophile Class B Adcom pre. Anyway these older components sound amazing together. I have two systems I like them both equally even though one is more expensive.

I am looking at one for on this site, for sale now- do you have any idea of what I would expect for repairs to keep it running another 10 years? 

Spare right & left circuit boards would be nice to have. My former EX4420 was a nice sounding amp I enjoyed for over 20+ years. It got rather hot and parts inside degraded over time, hum. Had the boards repaired multiple times until I sold it for parts, unfortunately. ATI amplifiers bought B&K brand, and designs, seemingly no leftover parts. Called them multiple times with little luck or interest on their part.
