1008.0. "COMMENTS ON NEW YAMAHA CDX700u" by USAT03::MLANDERS () Wed Dec 09 1987 05:49

    I recently had the chance to "test drive" the new Yamaha CDX700u
    CD player, and was quite impressed with the quality of sound.
    Apparently, Yamaha uses 3-beam, 18-bit, 4x oversampling to improve
    over last year's models.  Stereo Sound in Greensboro, NC sells the
    unit for $415.00.
    
    Does anybody have any experience with this deck or with others using
    similar 18-bit, 4x technology?  Are there other machines out there with
    similar technology in the $400 price range? 
    
    Thinkin' about buying...

Mark,

I've had mine since March and it's performed flawlessly since then.  I
probably average 3 hours/day with it and I have not had any problems
yet.  The only thing I might have looked at instead of the Yamaha, was
something that provides a way to play multiple discs.  I play a lot
CDs on the weekends and it would be nice to just pop in 5 or so and
let it play!

Good Luck

Dale
1008.2I'm in the same boat..KYOA::ELZAMSWed Dec 09 1987 15:549
    I am in the same boat as .0, and have recently picked up the "Best
    Audio Gear of 1987" by Audio magazine. The review of the Magnavox
    CDB 650 states that it may be the best sounding player yet made.
    I would like to know if it compares to the Yamaha, or for that matter
    any other player made...  Also does the lower priced Magnavox players
    sound like the 650?
    
    Also looking to buy.................Scott
    
1008.3The more opinions, the better.....USSCSL::JLAWRENCEMon Dec 14 1987 07:2226
    
    I would like to reference you to the AUDIO notes file for a discussion
    on dithering and quantization which addresses the Yahama technique
    for 18 bit playback.  There are only 16 bits to work with on the
    CDs themselves.  The "benefit" (depends on who you ask) is in HOW
    the 16 bits are used.  This technique was developed to try and deal
    with the inaccuracies of CDs when trying to reconstruct very quiet
    passages.  This is the area which is hardest to deal with.  However,
    from a tonal balance and timbre perspective, most reviewers have
    the most problems with the high frequencies.  A lot of folks feel
    that CDs cannot properly reporduce the "air" around instruments
    or the "wood" sound of strings.  Most of this is due to high end
    shortcomings woth CDs.
    
    The jury is still out on this technique.
    
    On another note(no pun intended), after you read Audio magazines'
    top best issue, check out two other magazines: The Absolute Sound
    and Stereophile.  They are independent, subscriber supported high
    end mags.  For a feel of how these guys think, look at note 1252
    in the AUDIO notesfile for Stereophile's list of recommended gear.
     The Magnavox units are quite good, but there are those who feel
    there are many better.  At least it will give you additional input.
