I wish there was a shop @jason-mc9. Why I work on my own equipment. New vs vintage really isn't a fair comparison unless capacitors have been charged to match new performance.
I have always heard huge improvement over a recap. 40-50-70 year old capacitors just don't work the same as new.
@curtdr nr1200 marantz? I would have to take a listen. But I directly compared a marantz 7t with marantz 16b recapped serviced. Upgraded signal caps, filter caps, change out of spec resisters.
I compared it to a Marantz PM8006 integrated $1500. There was no comparison with 7t and 16b were so much better. Friend has a marantz 30 class D integrated, he was shocked I really wanted to like the PM8006 but felt sterile, flat cold. Nr1200 being more of an intro amp. I don't see it beating PM8006 or a dual mono block separates from the 70s.
22xx serial 1970s I could see it beating it but I am open minded take listen when i get a chance.
