Classic el34 tube amps versus current models

does anyone have direct listening experience on how the classic el34 tube amps of my youth (marantz 8b, dynaco stereo 70', conrad johnson mv45) compare sonically to the current el34 amps? i have seen some of theses older units for sale and have considered buyin one. i am in the market for a 2k -3k amp and saw an old marantz 8b in that price range.

i am a sucker for midrange and soundstage and listen to alot of female vocals. my speakers are original rogers ls3/5a and proac tablettes, both of which love the el34s.  i am inbetween amps right now, buthave recovered from a financial setback so i am back in the market
