    Rega Apollo: decent transport

    I'm a binge listener; I can go months without firing up the system.  A disc on the JVC micro system or college radio on same.  A binge started a few weeks ago.  Some years back I decided that I should get a new player, since the Adcom GDA-600 was already old, and the Yamaha player even older. ...

    IEM & itchy ear

    I do like the sound of my ER-4S, but with either the flanges or foamies, my ears start to itch after a while. There have been some msgs. about the JH-13 being really good. But, I wonder whether mold based IEMs are immune to that? If so, another justification for spending all that $$$.

    Headroom Home innards

    I've got a Home from 1997, which had been stored for most of that time. I got it out. Sounds pretty good. But I figured swapping out the caps and resistors for top quality parts might be a good thing, given their age. Contacted HeadRoom about upgrade, but none left and they don't do parts...

    Apollo issues: long known or am I the first?

    1) the Programming steps say to hit Program after selecting the tracks. if I do that, the Accepted display comes up, but then the menu displays all tracks. if I hit Play after entering the tracks without waiting too long, then the menu displays, and ticks off, the chosen tracks. 2) discs that...

    can high(er) impedence phones mask amp noise

    my SR325s have been repaired twice by Mr. Grado; i just got them back again not too long ago. so, there is a static, crackling noise in the left side. it doesn't sound like intermittency. much like the static of AM radio. the pot (a TKD 25mm, no slouch) would crackle in low end travel...

    DualDisc -- in what way not RB??

    i've searched threads and web, but haven't found an explanation of what not RedBook means for DD? is it just the physical dimensions, or is it also the datastream, which is bad??

    identifying 325i drivers

    long story, shorter: i got my 325s back from Grado (looked like both drivers were replaced, or at least the white grill mesh was) about the time that the 325i was available. Grado had the phones for a rather long time; maybe in the midst of switching drivers?? now, i had just gotten my K501s...

    piano bass duo??

    watching Indy beat the crap out of the Pistons (well, may be not the same game you're watching) and listening to "Soundposts"/Eric Watson and John Lindberg. always liked left handed piano players and bassists who use all four strings. which raises the question: any favorites out there for...

    oh the horror: remarried my 325s

    must have been some mystic celestial alignment which moved me to take down the 325s (vwap-ed) and put up the K501s. first thing i did was put on the MoFi test disc. my transport is no big deal, an old Yamaha CDX-660, but the Adcom GDA-600 is said to be (still) quite good. the amp is a very...

    Sonya Kitchell

    so, anyway, i'm stopping at my local head/cd shop to pick up 'infinite possibilities' (Amel Larrieux); but it hasn't come in yet. so The Big Guy has this review of 'cold day' by Sonya Kitchell. who?? 16 (15 when the recording was done) year old from, of all places, South Hadley, MA (a very blue...

    pot static and cold joints

    when using my SR-325 (32 ohm) there is some static, mostly one side, at certain points in the pot (TKD 25mm) rotation. not so when using the K501 (120 ohm). a thread search yielded the wisdom that such noise can be due to a cold joint on the pot. if so, does anyone know how that might...

    it's the mastering <sigh>

    or maybe, yay?? i've had a copy of "Graceland" for years, with a big honking scratch. i periodically buff it out so the disc plays. been meaning to replace it. so i see that there is a re-mastering with 3 alt cuts. stop at my local head/disc shop, and they order it for me (Paul Simon...

    static/crackling in a tube amp

    what i thought was a headphone problem looks to be in the amp. but what is happening is not obvious. i hear occasional crackling or static-like noise in one channel. just for yucks, i "wiggled" the output tube of that channel: induced crackling. switched tubes. same thing. opened up the...

    i found the yeti (vacuum tube division)

    stole a few minutes in cubeland to read Joe's 12AX7/5751 piece yet again. just got a Raytheon from tubeworld, so, of course, i had to start swapping the (still small) collection. in his top group he talks about an odd RCA, with metal clips on the plate nubs at the micas. he goes on to say...

    K501s do DO bass, redux

    "Shock the Monkey" is thumping eerily away. now, i've never owned a Gabriel disc or album; just heard him on the radio. which is what happened on the way home from cubeland. for those who don't pay attention, the Blue States are about to get a foot and a half of snow, so i stopped at my local...

    TKD pots

    decided to convert my original MAD Purist to HD no-LED, rear power switch format. partsconnexion lists a TKD pot, and i saw a msg either here or maybe diyaudio that they're are kind of nice. i had the Noble notched plastic pot, and found i really didn't like the stepping. like butta, as my...

    grado customer service, better than i thought

    fair's fair, so............ got home, and the 325s were waiting. been enough weeks, i didn't expect to see them again. (got 501s winging their way from Todd.) sound is now properly balanced. there is hope for mankind.

    zorn & masada string trio

    whilst surfing amazon, i did a check of john zorn. seems that he recently turned 50, and is putting out a series of discs recorded (at a series of concerts) in honor. the first was listed, and had one very nice review. wandering in borders, well there it was. and only 15.99 (low for a borders...

    Time Out with Dave

    been a long time since i'd played 'Time Out' by Brubeck. this is the gold mastersound version. what's utterly mind boggling is the engineering. even on phones, it sounds like a group playing in a space. classic music, too. check it out.

    copper grid posts: difference??

    for no particular reason, i unholstered my sherlock holmes signature magnifying glass, and set out to closely inspect my 5751s. various makers, some with copper grid posts; others not. i had always assumed that the pins connected to the grid wire. it looks like the connection is to one post...

    output tubes *always* most important??

    there were some recent msgs. to the effect that rolling output tubes was way more important to sonics than drivers. this is counter to what is acknowledged about the MAD amps: doesn't matter a whit which 12B4As you use. so, out of overwhelming curiosity, how come? possibilities: - the...

    Another Reason to Skip Grado

    well, i finally realized that the 325s that they had worked on (right driver was grattling) had, basically, no response below 100Hz in the left channel. i tested with the "Sound Check"/MoFi gold disc. got a snitty reply back: "use them for 50 hours". dumb bunnies. i told them the driver...

    anyone replaced an Adcom GDA-600?

    so i've got this, for its time, state of the art DAC. but upgrade-itis is setting in big time. on the other hand, there's no sense in accidently being retro-grade. what have folks replaced it with (CD player, not DAC) and been glad they did?

    input: dual or single triode

    there is a msg on Amps/singlepower rants to the effect that the poster wouldn't touch an amp using a dual triode input: it's too cheap and tacky, essentially. but that raises the general question: is there a readily available single triode which is electrically equivalent to the 5751 section...
