  1. The R909 is more fragile than the R900. I have them both and I´m afraid they all aren´t the most robust units. The last indestructible unit was the R90/91 IMO.
  2. The problem of the bending casing was exaggerated IMO. The MZ-R 50 bends too if you push the two buttons beside the display with too much force. I have yet to find reliability problems for R 55 models. And you´re right: the R 55 is beautiful.
  3. No one should be 'coerced' into buying MD related stuff for inflated prices. For Christ's sake, this technology simply isn´t worth that much money. And it certainly isn´t suitable for promoting a sale on a forum that mainly deals with information. So I´ve voted for the last option.
  4. "The market" determines their worth? Well, "the market" usually has no idea about quality - because in this case it consists of a few dumb people believing in a myth. The TDK significantly colours the sound and is far away from the original sound. But I´ll give you advice regarding your "market": you should extend shipping to Europe. Here in Germany for example, Sharp's last MD recorders with 1-bit technology are highly sought items, fetching rather extreme prices (and they too are not worth their money). The same goes for any HiMD device and the accompanying HiMDs. Happy? If so, s
  5. They are. And not worth it. Haven´t ever heard the md2000 but I cannot say anything good about the tdk. You answered this yourself with the question
  6. Nope, sadly I can´t. I´d wonder if you actually found something as no one ever bothered to measure the ATRAC encoding (doesn´t make too much sense anyway since it´s a psychoacoustic algorithm). The main resarch regarding ATRAC happened before the net took hold; secondly, the guys that were doing all the measurements were audio magazines. But they weren´t measuring everything. I didn´t even know that the phase error existed before I measured it myself. Furthermore, not every unit is perfect when it comes to playback. My recently acquired MDS-JE 530 for instance produces a phase error on
  7. I offer another alternative: keep it. I have kept every - I repeat: every - little recorder I acquired on eBay, even the ones I used for spareparts. I do this because I love them and not because I want to trade them. EDIT: I was lying. I threw away a broken Audiophase MDP-1 and a broken MZ-R 501, both completely beaten up. I´d sell some of my portable CD players though. The ones I don´t like. Though I´d rather give them away for free. Which creates the situation that in the end they won´t turn up on eBay or anywhere else. Correct. 'Nuff said.
  8. No, they wouldn´t have advertised this. Almost no one I knew / still know cared for the ATRAC version on pre-recorded MDs. When ATRAC 3.5 came out on the MDS-JA 3 ES, Sony produced a pre-recorded WideBitStream MD. It was only to show off the 20 bit capability of the WideBitStream feature and wasn´t available anywhere. There was only one publication that ever pictured it (German STEREO magazine). To my knowledge, no other pre-recorded WideBitStream MD has ever been produced - though it´s very likely to say that Sony from 1995 on used ATRAC 3.5 for pre-recorded MDs and continued to imple
  9. Yes, I got it - but it doesn´t change the fact that it´s still stupid to think that one recorder would be better suited for copying than another. Do you have proof? You can´t take the sound as proof, it´s completely subjective. You need measurements and compare an ATRAC version of a professional pressing plant encoder to a home encoder. And I highly doubt that Sony developed the home version while they left the pressing plant version at ATRAC 3. For all of you who want to compare a home recording from CD to a pre-recorded MD: be careful. They sometimes sound different. Not
  10. Do you have any idea what we were talking about? Do you have any idea what you are talking about?
  11. 1. The frequency cutoff doesn´t enhance the bass. For us humans it´s close to impossible to hear frequencies beyond 15,5 kHz and once you reach a certain age you cannot even hear beyond, for example, 12 kHz. This cutoff is very unlike an EQ where you mute treble which in turn 'amplifies' (that´s how you perceive it) those frequencies that are left. 2. The encodings for pre-recorded albums are completely different to those produced by portable or home decks. With encodings done on portable or stationary decks, the cutoff depends very much on the frequency content. If the level of anything a
  12. Yeah, you did The first two ATRAC versions indeed had a cutoff at 15,5 kHz. But since ATRAC 3 the encoder tries to keep frequencies above 15,5 kHz. The frequency band from 15,5 to 22,05 kHz is just the last frequency band ATRAC tries to encode. The first ATRAC versions couldn´t handle it (not even on pre-recorded MDs) and therefore erased it entirely. But ATRAC 3, 4, 4.5 and Type-R/S try to keep as much as possible without hurting the rest.
  13. Recently I bought an MDS-JE 530. I already owned that model 15 years ago but sold it some years later. Now I own it again and it has the same encoding quality as a MDS-JB 930 QS. The only difference is the bit-depth: the 530 encodes and decodes with 18 bit precision, the 930 with 24. Curiously enough, it doesn´t have any effect on the sound quality. The bit depth may be different, the quality of the encoding is not. Meaning: both are way superior to portable machines when it comes to encoding quality. I very much assume that it´s the same case with your MDS-JE 470. So, if you´re record
  14. Judging from its frequency response, the Shure wouldn´t be my cup of tea I think. It has a very prominent and fairly wide peak around 10 kHz, muted deep bass and slightly diminished mids. In comparison, it´s no wonder that the Momentum ends up muffled. The Shure has too much treble, the Momentum not enough. Today, headphones are engineered differently compared to several years ago. Reason is that several companies have started to incorporate recent 'discoveries' regarding headphone sound. People experience playback over loudspeakers less direct and more muffled. Headphones now tend to
  15. You´re effectively transcoding from one lossy format to another. The first encoding produces several artifacts hidden by the louder music, that´s how lossy codecs (all of them) work. The ATRAC IC (just another codec from a data standpoint) treats these flaws hidden by music as one thing only: music, as it cannot differentiate between errors and actual musical information. Therefore you add one error (now produced by ATRAC) on top of the other. That you´re not hearing artifacts is a lucky coincidence. Erm... not the best idea. Most PCs nowadays have an optical output.
