Will the sound quality deminish over the years?


I bought a set of used B&W 802N and see a lot of nice speakers for sale here. I wondered if the age of the speaker would cause the sound to degrade. Sure, I have heard people state how great their 40 yo speakers sound, but could that be like shocks on a car? You won't notice how much less they are until it is changed.Just a curious thought as to 10 - 20 years down the road, can I expect the speakers to sound as good, especially when laying out a lot of quag.

Nonoise, I've owned alot of tuners and in house demo'd (sp?) quite a few as well. There is a quite a difference in sound quality. I'd say get another tuner. If you liked your 4300, get another. I enjoyed the NAD 1700 pre/tuner for a long time. Having tried out the ST-6000, was not impressed at all. But alot in this hobby has to do w/synergy. I'm enjoying greatly my bargain remote-control AMC T7 tuner bought for a whopping $20! Sounds fantastic w/the other components in my system. Go figure....this tuner got the most a terrible review! (Probably a defitive unit?) Anyway, get another tuner to enjoy, life is too short. Bill
Thanks Kotta, will do. It's nice to back on a quest for something better. It's what this hobby is all about.

All the best,

Nonoise - I like how your perspective shifted from the Marantz lacking the highs to it adding mid and bass. The change in perspective caused you to no longer think of it as not sounding as good as the NAD. Now that your assumption has changed for the Marantz, you will likely enjoy it rather than wish it sounded like the NAD. You may still prefer the NAD, but I am fascinated by how our brains work.
I'm not sure about tweeters in my Hyperions HPS-938 but midrange uses ferrofluid for suspension. Ferrofluid dries over time and has to be replaced but I don't know if it is 10-20 or 30-40 years. Also, some speakers have electrolytic caps in xover but it should last perhaps 40 years in room temperature.
As you bring more LPs, more DVDs, more books, more magazines and more of anything with barcodes on them into the house the sound will degrade to the point where it sounds very compressed, very generic and very amusical. Kind of like it sounds right now, most likely, now that I think about it. No offense intended.
