Will the sound quality deminish over the years?

I think Rocc1007 says that in jest.

Recently I had to replace my NAD 4300 tuner as it just stopped working (after a couple of decades) and replaced it with a Marantz ST-6000 which has all the bells and whistles one could hope for (presets, remote, great selectivity) and a very positive opinion from fmtunerinfo.com. Having said that, it's frequency range is 20Hz to 15KHz and these 60 year old ears can most definitely hear the upper end roll off and it was offputting at first, to say the least.

I got it for a great price being an old demo but I'm still looking for another tuner that can at least replicate the sound of that old NAD. I really miss the air, ambience, sparkle and whatever else lurks up there in that other 5KHz that was left out in the design of the Marantz.

As for your question, the surrounds of the speakers won't be up to par so if it at least looks to be in decent shape, I wouldn't push it with the SPLs. :-)

Doah!, I'm channeling Homer Simspon as I pen this.

I didn't know that. Going back over the reviews of the Marantz tuner I see that it's geared for a great midband and bass so maybe it's that that the NAD lacked which made it seem able to go higher.

Thank you Phasecorrect for saving me the trouble and costs of seeking out a new tuner. :-)

Thanks Kotta, will do. It's nice to back on a quest for something better. It's what this hobby is all about.

Mceljo-good point. My first reaction was something like "who covered my speakers in cheesecloth?", it was that big of a difference. Although I've written off the tuner since I got it for so little, I'm still not used to the trade off in sound. Having a bigger and fuller mid to bass response is nice but it seems to dominate the already limited frequencies in a disproportionate way. I guess one can say it has that classic Marantz house sound from the 70s. I once inserted an old Marantz receiver (I believe it was a 2030) into my system and the sound was very similar: big, full and wooly.

Like Kotta pointed out, different tuners will sound different in the context of any given system, just like any other component.

All the best,
