    I visited my soon to be 93 year old father over the week end and had to get his "system" up and running for him.....again.

    He has an old Fisher receiver from the 70's that hardly works, an old something or other turntable and a dried out 10 inch speaker system.

    So the turntable wasn't sending anything to the amp and it was buzzing and popping or doing nothing at all. So first I had to check out the wires coming out of the arm for continuity, then the RCA cables that were patched together in four different places with wire nuts and electric tape. Next I had to remove the input jacks and re-solder a wire onto one jack. The turntable selector switch needed cleaned but I'd have to disassemble the whole cabinet as the top is not removable and he didn't want to do that.

    Still didn't work so I pulled the needle cartridge out, removed all the wires and cleaned the posts, connectors, and needle. Then it worked if you ran it in mono but not stereo, so I hoped he wouldn't notice. He didn't.

    For a little while, then it quit again, so I took the cartridge out and jammed a little piece of notepaper stock under the contacts to raise them up for better contact. Then it started working in stereo, but not mono. So I said, "Good enough, don't touch anything."

    He was happy, we put on a Mitch Miller album, the Ink Spots, and Doris Day. Not much bass but it works and he's happy.

    I keep forgetting to look at Good Will for a new system for him.

    I still like the tube amps dont care how old they get. heres a tip for speakers with paper cones, take glycerin and water 50/50 and lightly spray the
    cone. water will evaporate leaving the glycerin behind. also speakers with linen surounds will last forever. parts can be found at simply speakers.
    nothing sounds as good to me as a bass speaker in a 2-3 cuft box

    Not exactly on topic, but good music.

    "a garage band....

    This is my hifi system, I don't need anything else.

    Xiaomi Bluetooth box $25

    Xioami Piston earphones $25

    And of course my smart phone. Technology is great.

    I had those same speakers for 30 years, gave them away earlier this year.

    But you no longer need a hifi system to listen to the music.
    Reasonable cost personal earphones have way better quality sound than really expensive speakers, and you can listen without interruptions.
    And the small portable boom box lets you share when you want, wherever you are.

    Big hifi systems no longer serve any purpose. Small has replaced big.

    True, unless you respect quality sound.

    - I like the surround -a - sound experience, earphones can make music more personal, but has a degree of anti-socialism about it, small portable boom boxes have a tendency to be bass-y - I think music it is for sharing ,,, so I do :)

    They've only replaced it for ordinary convenience. In many states they are illegal to wear while driving and, for example, you can now buy a car with a rear windshield that is also a hi-fi speaker. This year several manufacturers have come out with different speaker systems that put out true 3D sound, not surround sound, but 3D where, among other things, you can hear someone whispering behind your ear that the guy next to you can't hear. Theoretically, the next step is using transducers which can mix inaudible sounds in mid-air and can even follow you around the room so that every person in the room can listen to something different.

    Some like to say, "Reality is analog" and sound is best reproduced using analog hardware. The first "perfect" microphone has just been produced that collects every sound wave hitting a wall and preserves them as a single wave-form the length of whatever wall you are using. Using memes technology, in the future, computers can even be built that use vibrating combs to do the processing meaning the entire stereo is spitting out essentially the original sound after playing with it.

    Next step is a direct brain implant of the media player, that automatically debits your bank account every time you hum/watch/listen to a copyrighted song.

    I like to share in the bedroom, on the patio, on the beach, in the jungle ......... you can only share in your hifi room.

    YUP,
    Guess some folks don't understand that you buy the 600 watt system because when you listen at a comfy 50 watts it sounds FUCKING BEAUTIFULLY PERFECT!!!!!!!

    The best systems for sound reproduction are still bulky and use vacuum tubes, but now they cost $$$$$$$$$$$$$$$$.


    and sorry to break it to some of you, but digitally reproduced sound is NEVER a true reproduction, by breaking the information into discreet digital packets there is a loss of info, even with "lossless" formats like FLAC there is still some info missing.....analog is the way to go baby.

    Too many variables. Acoustic properties of the room, walls, tables, furniture. None of those problems with in ear devices.
    If you're over 40, you probably can't hear most of the higher frequencies anyway.
    Not to mention, most of the stuff (to which you listen) probably was't recorded very well in the first place.

    PS
    600w speakers operated at 50w levels will be distorted, you ain't feeding enough power to overcome the inertia of the cones.
    50w driving 100w speakers will probably be OK.
    That's simple physics.

    Nah, the Pentagon and NSA tend to sit on that kind of advanced technology for at least twenty years.

    Not disputing how room environment plays into listening to music, but when it comes to the equipment for sound reproduction, my comments stand.

    So are we to assume that what you listen to was recorded perfectly and please do tell me what I listen to.....

    too many assumptions in your premise...



    and still looking for an "in ear" device that can give good solid bass you feel in your bones.

    I used to work in the sound recording studios in London (I won't say which one) but we didn't take all that much care with our recordings (pop/rock/metal).
    And our equipment cost more than you could imagine ........... most of the time the 'artists' provided too much free drugs for anyone to do the job well.
    The important bit of the job was to get the recording done before the artist threw a tantrum and stormed off or passed out through drug abuse.
    Not to mention, we all sniggered at the guys with record players and valves ................. none of them ever got to work in the studios.

    Don't know about classical ....... they couldn't afford me.
    And we were all through by age 45 because the noise levels damaged our ears.
