Some components too old now?

I'd be Excited for your Old!  Depends on what your trying to accomplish with "Any NEW??"   I just Fired up all my Old.. too much to list, yet the Old Power Supplies are the BEST! -- I have a 1992 DAC from Howard Mandel who since passed - seperate power supply and compared to New DAC's and you have to spend 5K Plus to out preform that - his CD Transport too, Thiel Speakers, Maganapan's, old Kenwood reciever in wood case and so on..  MOST Important Clean, Blow Dust D irt out from Air vents on side, better yet take the top/side off and Blow out Good.
Clean all your RCA's and if they are the el cheapo's get good ones you will notice a difference.. Good Luck..

I’m still using a 1964 Sansui 1000a tube receiver with a modern dac and newer speakers. Sounds great. Just had it completed rebuilt. Should be good for another 20 yrs.. The worst thing is purchasing the 7591a power tubes which are expensive. I agree with other members and would look into a nice dac. 

It not that costly to upgrade your components.  Amps usually have large capacitors with two leads on the top.  You can just match the values and swap them out  just measure the new caps and the clamps prior to ordering them.  Nichicon you can buy at Parts Connexoin in Canada, etc.

Just saying

1984 Klipschorns, NAD 1600, Mc 275, Mcd 707 the Node 2i is the only thing new. Happy with all of it, solid old equipment beats the snot out of a lot of the expensive new stuff. There was much greater sales volume of HEA in the 70s and 80s, more volume = better profits = better r&d. Imo those solid old components can't be beat.  I listened to a set of speakers the other day that darn near made my ears bleed, they cost as much as a house and had diamond tweeters, and sounded awful.  Certain things just work, tubes,horns, solid engineering. 

Of all the things mentioned I would say the DAC is the main piece I would upgrade and the CD player last. That or a an updated mid to high end CD player with a better built in DAC than something from 1990.
