MT770 review - Page 2

post #16 of 54
hm, Sharp still hasn't updated their European sites, no mention of the new models (except for the 880).

what's the 190 look like?

Braver, here's the link. Scroll down till you see Sharp's MT180 and MT190.

http://www.sinsiamelectronics.com/minidisc.html

I posted this a couple weeks ago. On the MT190 page, even if you don't read Thai (I don't), you'll see that Li-ion phrase in the descriptions.

wow, Li-ion battery!

it only gets 14.5 hours from it tho, 26 in LP mode (I admit guessing here, but the 40 seems to be antishock, and in combination with the mention of RAM, I think it's playing time).

it's not as cute as the 180 tho, but it seems they really cut down on the features for that one, including a cut in shock resistance.

I must say I'm not as compelled to check it out as I was when the mt80 came out. not a big improvement from the 88/99 MDLP recorders. they are getting smaller tho.

Where exactly did you sight this MD-R, B? Inquiring materialists want to shed cash-wads on vintage Sharps.

I saw it at a Dixons in Delft.

funny how that store changed BTW. few years ago, all they had were computers, then they slowly began selling some mobile phones, then they picked up on the portables market and now they have all sorts of nice stuff for usually better prices than the more specialised shops. don't go there with questions tho, they don't know jack :/

Thanks for your swift info lob. Question: Does Dixons have a mail-order cattle-log or website, hmm? My only pal from the Netherlands just moved to Thailand, so I doubt he'll be bringing me a Sharp with the festive eggnog.

Thailand? There might be hope.

Earlier in this thread I posted the URL for pictures to the Sharp MD180/190. The website is from a store here in Bangkok, located near the very (in?)famous Patpong. I was in that store on new year's eve, and saw an 831 on display.

I'm sure there are more 831s around some of the department stores in Bangkok too, so if your friend's in Bangkok, you can still ask him for the favor.

And I'm sure we've got eggnog in Bangkok too.

The other place on earth where I saw the 831 was in Shanghai, China. But it was in one of those state-run department stores, and they always charge ridiculous prices that everyone goes to the small vendors.

they do have a site, but the 831 isn't mentioned on it. it's also the only Dixons store that I saw it in.

Leon,
I can assure you that there are more of 831 in BKK area. I just got back from Bkk and I saw atleast 4 or 5 of the 831 in the MBK center. So ask your friend to go there and get you the 831 dude!!!
What's the hype about the 831? I got sharp Md-SS323, have u ever heard this model, Leon? Thanks for the comment.

purk,

The "friend" I mentioned is scrypt's friend. I'm living in Bangkok right now, and only visited MBK last week Plus, I still have an 831 and an L7R, both in working condition.

The 831 is, IMO, just the right combination of size, interface, and sound in a way. The button layout is better than the 77; the battery life is longer and display text larger than the 702 and 722; the looks is less tacky than the 821.

The sound is great in an almighty way - plug almost any headphones into this thing, and it'll sound good. It's just really sweet-sounding. 10+10mW amp (@32ohm) does give it some "richness" that the 77 and 770 don't have, but at the same time it's got more highs, than the 702.

The 831 doesn't sound good just because of a pleasant low/mid/high combination. IMO you can really hear its ATRAC decoding capability shining through. People from the Sharp booth at Audio Expo '99 in Japan also told visitors that the 831 has a greater decoding capability than their player-onlys.

While it may not have the Burr-Brown DAC (that the MS100 or 200 had), it's quite a good combination of things. If you ask me, it's not hype; the 831 really is a good package.

A friend of mine has the 323, but he uses other portables most of the time (Sharp 821, etc.) so I haven't heard much, and can't comment on the sound.

Another Technical Addendum !

As you may have noticed, minidisc.org has a service manual of the MT77/877. I downloaded it... Here are my discoveries:

(1)
IR3M59N is the headphone amp. On the schematics (or whatever it's called), this IC is shown to be connected to the phones jack; the other IC listed as an audio amp, the 54N, is not.

(2)
IR3M14N is indeed a DC/DC converter. Like the MT770, the MT77 has two of these installed. They don't seem to be connected to each other. One of these supplies +1.5V and -1.5V to the 59N (phones amp).

(3)
The MT77 and MT770 seem to share most of their components. They use the same ATRAC, DRAM, phones amp, RF amp, DC/DC converter, among other things. However, the key combination that enters service mode on the MT77 doesn't seem to work on the MT770.

Edit - I edited the review to combine the original review and the addendums. That version is now online at:

Two questions for Leon

The others were right -- you really did offer the most most pertinent info of any reviewer about the 770/880 (relationship bwtn batteries and recording quality, ATRAC number, etc.). It was your review that convinced me not to buy the 770 (or perhaps even the MT77/877).

I still have two questions, though.

1. Which in your view produces better sounding recordings in SP mode, the 77/877 or the 909?

(Users have begun verifying what I thought would be true: that the difference in quality btwn R-ATRAC and earlier versions is perceptible and demonstrable.)

2. Which has a quieter motor, the 909 or the 77/877?

(I own a Sony 900; the worst thing about it is the motor, which will interrupt recordings at UN-protest-meeting volume if the mike actually touches the machine. I sometimes use an otter box with imbedded microphones for ambient recordings, which works well with an M1 DAT. I can't say the same for the MZ-R900. The next MD I purchase should not have a motor noise problem.)

Okay, I haven't heard the R909, but I'll try to answer your Q's.

Since last year I've promised myself that, when I buy a MD recorder, I want to have type-R. It is the best ATRAC I've heard, and if MD can be as good as that I wouldn't want any less

Having said that, the reason I bought the MT770 is that I'm using it primarily for playback. I've still got another recorder for SP, and I want to wait until I'm back in the US this fall, when I can get a cheap deck with type-R. I prefer Sharps for playback.

A while ago, I did an unscientific comparison of the MT770 and the Panasonic MR200 (my usual SP recorder), using Natalie Imbruglia (told ya it's not scientific). The MT770's ATRAC is Sharp's version 6 (the same one from the 877, 831, 821, 722). Sharp goes for a forward delivery; there's more emphasis on the "edges" of the sound, which makes the whole thing sound impressive, but also fatiguing after a while.

The Panasonic's ATRAC is more laid back - just like type-R - as in, they feel smoother around the corners. Both of these attempts to offer an impression of wide soundstage, by placing a bit more emphasis on the lows and the highs. Sharp 6 is actually the most true to ATRAC principles, but compared to these two it can sound "boxed in" and narrow. If you're not listening to modern rock, the other two has a chance of shining through.

So, if the R909's type-R is not substantially worse than the JE440 deck I heard - and it shouldn't be - I definitely recommend it over any Sharp, for recording purposes.

About the motor: The 909's spindle still runs way faster (IIRC, in the 3000rpm ballpark) than any of the Sharps (~1350rpm).
