I'm a fan of whatever works well, and sounds good.
Depending on the equipment, sometimes the older stuff sounds better, sometimes the new stuff does.
I've found that with radios, specifically AM radios, the older units sound MUCH better then the new ones.
As for CD players, for me it seems that the newer they are, the better they work. I had a very old "professional" CD player (top of the line in the mid 80's, has balanced outputs), but it doesn't hold up to my cheaper consumer grade player that is much newer. Part of the problem is it's total lack of any kind of anti-skip/buffering technology.
As for turntables, I've got a SL-1200. Mine isn't brand new, but it's not a 70's era model. I've compared it to the brand new SL-1200 that we have at the radio station I work at, and it works just the same. (I use the same pre-amp and cartridge/stylus that the station uses.)
I've got an AKAI 1730-SS Quadraphonic reel to reel player that doesn't see much action because I haven't been able to find any tapes for it, and the record head isn't working right now (I'll have it fixed soon.)
I'm presently using an old school AKAI receiver to drive everything at home, just because I can't afford anything newer (and the newer stuff I've sampled doesn't sound quite as rich to my ears.)
So like I said above... I'm a fan of whatever works and sounds good, whether or not it is new or old.
