20 Year Old Amplifiers compared to 2017

I've tried several times to replace my 20 year old amps with something comparable in price... only to be disappointed.  I own 2 Brystons... I just had my 4B-ST restored (by Bryston... an amazing deal!) and am very happy to have it working again... sounding possibly better than new with modern caps.  I also have a newer 4B-SST2... which at twice the price, does not sound better in my opinion.  It's more refined, but less exciting.  My all time favorite amp (don't laugh) is my Nakamichi PA-7AmkII.  I had it restored/recapped and it sounded better than ever for a few years, but it's now nickel & diming me with weird power up issues.  I so LOVE this amp, but wonder how much i can afford to keep it running reliably.  This is the problem with big vintage amps.  No matter how great, they can start to develop weird little problems.   I also share with the poster above... that my trusty backup amp for 20 years is a Hafler P3000.... not GREAT.. but surprisingly good!!  

Like Lancelock I have an old Mirror Image Amp a very obscure company that only lasted a flash. I recently bought a first watt F3 amp and there was no comparison between the two on my Sunfire Ribbons. Of course the older amp would be close to $10 000 in todays dollars. having tried some Class D there is something to be said to good old Class A amps. especially because it is 1 degree F today.

I have one of the first Belles 150 's made, I reckon  it to be 28 years old .
Bought few years ago for $ 400 bucks from AudioArt, one of the best guys in audio, who had it totally recapped etc and hardwired with one of his excellent $500 bucks power cords as a project ,
It's in my bedroom doing the usual Belles clarity and tone thing, I truly believe it can keep doing it for another 20 years.

-12 F in St Paul as I type this .

Great thread.  I posted a similar thread not long ago and love to read everyone's opinions.
