20 Year Old Amplifiers compared to 2017

I don't think my 30+ year old refreshed amp would be terribly embarrassed by most of today's offerings.

Hafler guy here again!...:) My 9180 is 23 years young and continues to delight. I am not an audiophile in terms of knowledge or equipment purchasing power. An audiophile in terms of enjoying music since I was very young.
I presume there are many amps produced since Rockford Corp., stopped producing this gem that out pace it.  

Following this line of logic, the Bryson 7B is as good as the 7BSST, the 7BSST squared and the 7B cubed. The Pass Labs X350 is as good as the X350.5 or the X350.8.  How do they manage to maintain this farce?

@hikmer - how did you determine that the caps needed to be replaced on your CJ? Was there a physical clue like bulging or leaking of electrolyte or did the SQ change?

@mikexxyz In regards to the caps needing replacement on my CJ MF2300a, I noticed for a long while that my lower frequencies did not sound as even or solid as I thought they should.  I did some research and found a few companies that would do enhancements to the amplifier and when I sent a photo for the insides told me the caps were bulging which is a sign of capacitor failure.  I decided to have them replaced and there was a marked improvement but I have recently acquired a newly built DNA-1 which I find much better in most areas of sonics and performance.
