20 Year Old Amplifiers compared to 2017


Just a random thought, but I’m curious just how well the state of the art solid-state amplifiers from 20 years ago compare to some of today’s better offerings. For example, what does a pair of Mark Levinson 33Hs or a Krell FPB 600 sound like if compared to the latest offerings from Pass Labs or Ayre Acoustics?

Thanks for a great thread!  I am new to the world of higher end sound, but  wanted to thank the folks on this forum and Polk’s, for steering me toward a well used power amp. A year ago, I bought a pair of LSIM 707‘s, hoping to re-create the wonderful sound I heard on a friends high-end system when I was in my teens (in the 60’s).  Unfortunately, my home theater amp, a Denon AVR 1909, was not up to the task, so I put the speakers on ice until I could afford a better amp.   Earlier this year, I picked up a Parasound 2100 preamp, and as Christmas approached, I decided to see how much power amp I could get  in the ballpark of $1000.  I liked what I had heard about the Parasound A21,  but I  didn’t  have $2500 to spend on a new one, and I wasn’t sure I wanted to buy a used amp (even if I could’ve found a used A21 for close to a thousand dollars, which I couldn’t).  I decided to go with the A21’s junior sibling, the 2250.   Around that time, I started to hear  about the old McCormack DNA series on the Polk and Agon blogs.   I found a 20-year old DNA-1 Deluxe on sale for $1000, and decided to grab it and compare it to the new 2250.   Long story short:  The 2250 is a nice amp, but the old, dusty DNA-1 blew it away!  The new Parasound went back yesterday, and the McCormack will be staying (maybe someday I’ll pay for SMC or CJ to do the upgrade, but for now the stock Deluxe is all I need).  I’m a very happy camper, and am glad I listened to you all.  20-year-old amps are indeed worth the money, and more. If and when I  want to take my system to the next level, I suspect I will look into an even better pair of speakers.  But for now, I am just planning to enjoy a new level of audio for a while, rebuild my music library, and smile. Thanks, and have a Happy New Year!

My buddy loaned me his Muse One Hundred amp a few days ago. It's gotta be old. 15 years? More? Anyhoo, it's chewy textured delish. Love it. Making my speakers jump for joy.
For anyone that is uncertain if their 20 year old Krell or Levinson is still any good please send it to me and I will check it out and if necessary dispose of it in an environmentally safe way......
