559.0. "Advice before i buy CD player" by WAR750::MEAKINS (Clive Meakins) Fri Dec 05 1986 11:30

    I'm about to purchase a CD player (i believe CD and those old fashioned
    lumps of black plastic both have their places in my collection).  I 
    borrowed a Phillips CD150 and connected it to my system.  Most CDs
    sounded great but my favourite - Brothers in Arms - whilst sounding
    good, seemed to be very heavily biased to the top end.  I found it 
    difficult to follow the music due to the predominance of the snares.
    
    The only reason i'm making a big thing of this is that i'm told
    that Brothers in Arms is considered to be a very high quality CD.
    
    My question: Is this CD disc baised towards the top end or is what
    i'm hearing due to the combination of my system and the CD150?

    p.s. amp         - Musical Fidelity A1
         speakers    - Mordant Short MS15           
         intended CD - Phillips CD160

    ain't the case on my system.  Brothers In Arms is one of the best
    discs I've ever heard, and is very well balanced.  BTW, this is
    also true for this disc on a "super-system" (AKA BIG $$), down at
    natural sound.  Seems like one of your components ain't up to par
    with the disc....

RE .0

I'll go along with .1 - it's the best of my (limited) collection.

559.3Something else to think aboutRENKO::PROPPERFri Dec 05 1986 12:4611
    There is a difference in another aspect also. When an album is cut
    on vinyl the highs are compressed and the bass is pumped up. As
    my understanding goes (someone please correct me if I am mistaken!),
    this to make the grooves pack better on the album. What you are
    getting on the CD is the true dynamic range of the music as it was
    recorded. It could be a case that your ears aren't used to have
    those types of highs in your music. I also enjoy Brothers in Arms
    quite a bit and have found other albums to be similar in that I
    was used to the compressed version of the music.

559.4LP equalizationDSSDEV::STRANGEBeing for the benefit of Mr. KiteFri Dec 05 1986 12:5915
    I believe that when an album is CUT, the bass is attenuated and
    the treble is boosted.  As .3 said, If this were not done, 
    the grooves would
    be so wide (due to lateral variation) that you could fit only a
    few minutes on each side of an LP.  When the LP is played back,
    the bass is boosted and the highs are attenuated using a standard
    equalization circuit.  This should restore the equalization properly.
     If the LP has attenuated highs, it is the fault of the equipment
    or of the mastering process of the record.  An LP and a CD taken
    from the same master should sound very close to identical as far
    as equalization.
        re: base note
    I also have the Brothers In Arms disc, and I agree that it is one
    of the best recordings on CD--sounds great!

.4 is correct, and another reason of doing it that way is to reduce hiss.

    I found the disk bright, both on LP and CD.  Its pretty clean and
    not really nasty, just a typical treble boost pop producers like.
    There is also some nice tight, pretty deep bass which helps to balance
    out the treble - though your speakers (and amp) may not fully convey it.
    
    I have a Philips player (one of the 14 bit models - I don't remember
    the model number mapping to Magnavox 2041) that is modified and
    sounds good.  If you replace the electrolytic DC blocking capacitors
    with polypropelene's you can reduce mid-range harshness and add
    a little detail.  That $20 change will get you most of a Mission
    or Meridian.

    The CD150 would make a nice system with your good amp and speakers.
559.7Let me toss in my $.02NATASH::WAGNERFri Dec 05 1986 16:3817
    I know nothing about the design and specs of the CD150, however,
    I and a friend once did an A-B of our two players on his system.
    His player had 2X oversampling and digital filtering, mine was the
    more mundane 44.1k Hz sampling freq. with analog filtering.  There
    was a noticeable difference in the way that these players reproduced
    the high-end material on a CD which I would characterize as a
    raggedness and increased brightness in my player.  On such things
    as baroque strings on "original instrumentation", my player had
    a harshness which was not present on his.  You almost felt like
    you were only getting the higher frequency range of the material.
    
    It could be that you were experiencing the same phenomenon in your
    listening tests.  For myself, there is some music which I would
    rather listen to on a turntable (or my friends CD player) than on
    my CD.

Brothers in Arms in one of the CDs I listened to just before and just after
making the switch to polypropylene on my Yamaha CD-X1 (amp: the Carver Receiver,
speakers: JSE 1).  The difference in reduced harshness was quite noticeable.
