Vintage worth the time to explore?

Consider moving to headphones.  The best modern examples provide awesome sound.  I bought electrostatic Stax back in 1995 for late night listening in a flat and they remain superb.

@deadhead1000   Rubbish that nothing over 10 years old is good.  There remain and always will remain some wonderful vintage amps that are iconic.  I have three. Audio Research SP10 (OK a pre-amp), Krell KSA50, their first product and their unbeatable KRS200, now pushing 40 years old, serviced and re-capped of course.

I find your handle very apt.  Stay with it.

I am somewhat biased since I own a recently refurbished Sony TA-N80ES. It's the same as the TA-N77ES but without the meters so it doesn't look as pretty. However, it sounds as good since the internals are the same. You should be able to find one for less than $1K refurbished (recapped, new transistors, etc.). If not a used one will run $400-$500 and another $300-$500 to be rebuilt. I own other great new amplifiers and am very happy with this Sony. I use it for a 2nd system with some Focal Kanta No.2 speakers and the sound is outstanding. It also has an attenuator on the amp that helps at low volume levels but I have never had a concern with that. If you want a receiver with all the pretty lights and meters I also would suggest a Sony, the STR-V6. I own one of those also and picked it up for $650 rebuilt and it is a fantastic receiver. It is connected to pair of "vintage" Mirage M760 speakers and tey are a great match. A pair of them can b pciked up for $500. I think they should go for a lot more as they sound better than many much more expensive speakers I recently auditioned. And 115WPC of the STR-V6 is good enough for most. Similar Pioneer, Marantz, Kenwood, Yamaha, and Sansui receivers are going for significantly more. Otherwise, if you can afford $2K then go with something more modern. There are a lot of great amps out there in that price bracket, both new and used. 

Unless you are willing to resuscitate vintage electronics, I wouldn't bother. I do have some vintage source equipment (an analog tuner and a turntable), but modern speakers and amplification. A great used amp that will chill out your bright speakers or room is one of the FMJ series Arcams. A FMJ 19 at 50 watts/channel will cost about $400. Very detailed and good at low volume. Also a used Rega Brio would be about the same watts and cost. 

I asked the same question and asked for comparisons recently as you can see here:  

consensus was no, not really worth it compared to modern gear.  

I've wanted to like vintage electronics but not much luck,  until a found a refurbished HK430 receiver which sounds great with my Elac 6.2, but not in a large room...
