    it looks well made for a modern player! although as far as modern Japanese CD players go, I like the minimalism of the Sparkler audio units.

    here is a show and tell of the CD880 from my post above:

    [​IMG]

    pretty much a two-board construction not counting the display. the frame the boards sit on is cast metal, the steel chassis is copper-plated on the insides.

    [​IMG]

    the PT is universal voltage with jumpers located underneath the plexiglass cover. although from what I understand not all CD880s had this.

    [​IMG]

    the TDA1541 S1 in my unit is covered with factory stickers that I dare not remove.

    [​IMG]

    finally, the die cast CDM1mk2 rests under a spring-loaded clamp. I originally purchased this machine intending to apply all-out modifications and turn it into an end-game transport. I simply can't bring myself to molest it now, given the condition and crazy collector value on the market. I will modify a beat CD960 instead.

    In doing some research on this, I have found that it is totally surprising that even broadcast pro-level CD players would have KSS-240A optical systems, but I guess Sony was about the best in town in the mid to late 90's and even until the 2000's. But even the broadcast standard Denon DN-951A has a KSS-240A. This is for radio stations that play CD's ALL day. Same for the Sony CDP-2700. And likely the same as the CDP-3100.

    I also looked up the SCD-777ES, and that uses a KHS-180A, which is a dual optical laser. One for normal CD's (which is probably a KSS-240A variant) and one for high data like SACD, and does not even have AES out. The KHS-180A.

    Don't get me wrong, I am in the Philips CDM-1/CDM-9 camp and have a Magnavox CDB465 that has the CDM-2, which is the same optics as the later CDM-1, just in a composite housing, from what I understand. I just wonder about the old Sony optics (at least the KSS-240A), because I am really starting to like the post industrial looks of the CDP-2700.

    I don't care for chi-fi. $2500 is a lot of bones for a CDT, especially one where you are largely SOL if it breaks. you are much better off buying a vintage transport (doesn't have to be expensive or fancy) and modifying it to improve the factors I listed here https://www.superbestaudiofriends.o...nsport-player-thread.3028/page-12#post-362876

    from turnkey solutions I would much rather take the Sparkler audio unit or wait for the schiit transport

    Just throwing this out there as another option, but i picked up a used AudioLab 6000CDT a while back. Comparing between Pi2AES/AES and CDT/Coax is kind of surprising. In a nutshell, the AudioLab stages better, has more vivid macrodynamic contrast, and sounds more visceral in the midbass than the Pi2AES running into YggyA2. I'm pleased so far, but also kind of dreading when (not if) the slot load mech shits the bed... but, I'll use the time until that happens to find some other oldschool 50lb transport from 30 years ago.

    What music did you use to compare? And how did you match the source material between a CD and a streaming file?

    I forced a downsample to 44.1kHz using Roon, streaming Qubuz and local CD rips to compare sources/transports. The music that (for me at least) highlighted the minor differences in the midrange was on more energetic stuff like Bronson. I tend to listen at lower volumes, 65-75dB, and it could be the slight emphasis in the midbass plus greater macro contrast at lower volumes is pleasing, like a slight loudness button, when using the AudioLab CDT. Though, the Pi2AES streaming full rez (24bit, 48/96kHz) does have a little more sense of space, and the highs sound slightly more relaxed.

    The one imaging trick that jumped out to me more so with the AudioLab was comparing the 1st track on the new Low album HEY WHAT - the panning of the vocals in that song took on a greater sense of height (Alan Sparhawk's voice seems to come from the floor, panned hard left, to about 4 feet above the tops of my speakers, centered but still switching places with Mimi's voice).

    I picked up a PS Audio transport recently and am curious if something got damaged in shipping? It plays and reads discs without a problem but the mechanism is unexpectedly noisy?? I measure 65dB at about 10cm from the drive tray using the audiotool android app.

    Because I couldn't help myself I opened it up to see if some padding or stabilization mechanism had come loose during the journey but it was rock solid. What I didn't expect to find is a $20 Asus DVD ROM as the primary mechanism in such an expensive transport. The noise is similar to a PC drive but I have also heard many PC drives that are dead silent and I can't imagine that this is the norm.

    my question - if anyone has a perfect wave transport - is it noisy? If it was 10dB softer , I could live with it as music would drown it out but as is, I cannot use it as a transport no matter how well it plays back.

    I guess the next question would be , can anyone recommend a quiet SATA DVD ROM for me to try and substitute.

    ps - this little experience has reaffirmed why I hate high end audio and am a happier camper living the cheap bastard audio dream.


    EDIT - found the PS Audio forum and it seems a few folk have switched out the drives and not all drives are the same - so I am guessing any SATA drive will do it. Paul posted a comment stating that any replacement would not be specially modified to run at 1X but I can assure you this thing does not run at 1X - if it did, I wouldn't have this issue

    Although not sata, Apple superdrive is well damped and quite silent. Although internally it makes use of a LG rom .
    Among Sata ones LG 24ns** is pretty silent. Sony and Lite on are very noisy. Asus 24D5MT isn't as silent as the LG but to me has the best rip quality.
    Some older Sony models such as the 880s can be cross/custom flashed for a more silent operation.

    An issue with the Apple Superdrive is that it is a slot loader but has no way to mechanically force eject the disc (if you forget to eject before power down, or when something goes wrong). I'll bet that the OEM transport inside does have a mechanical eject (typically a small hole where you can insert a paper clip and push on a lever), but Apple didn't want to spoil their clean design with an extra hole next to the slot.

    To the noise issue on a PWT from PS audio, mine has been dead quiet for the last year I have owned it. Only one problem that a disc didn't eject ( that is a software problem once in awhile I have read) fixed by resetting off then on again to reboot it. Yes it's an ASUS DVD drive. They have extra drives from when I asked the question. This was a $3K drive, I did not pay that. I think PS audio is over priced anyway, period!
    I need a transport because I still play lots of discs.
    But.........it is a good sounding transport into my Yiggy via AES balanced.
