No treble controls. Sounds fine though without it. I remember from reading the manual it has an upgraded drive unit, if you notice when running it is the smoothest and quietest.

Inexpensive is good.

Thanks. Do you know if the unit automatically increases treble when bass is increased. I know some units work together this way.

I am 99% sure the MZ-S1 is the MZ-N510/520 in a water resistant casing. If I get time I will open up my one and only S1 and confirm, especially as there is some confusion over the type R/S status of the unit. Perhaps the S1 was designed using the N505/707 hardware, which then became the blueprint for the N510/520.

I would look at the chip numbers of IC801 in all of these models. In conjunction with the sequence posted in the MDCF equipment browser, I think the story is quite interesting.

There seems to be consensus that the S1 (which came out about the same time as the 707, the 707 certainly best-of-breed up to that time from all anecdotal accounts of users) may have had the later chip revisions of the CXD-2677 substituted as production continued. I found -202GA, -204GA and also CXD-2678 and -2680 in the various machines from around that time.

At what point there was a quantum leap, I don't know. Maybe they just decided to call it Type-S because some incremental improvement meant that someone noticed it was better? :)

The S 1 was not designed for listening "Hi-Fi", the use during sports activities makes it more of a "background music" rather than excellent fidelity.
I sometimes use it as I go cycling, and, honestly, does the work for which it was designed.
In my opinion sounds better than the N 505 (a lot) ....

I did not think that you're in favor of the transgenic... :-)

Just had a quick peek inside my S1, which states Type-R on the plastics. It has a modified N505 type board with a 2677-204GA. Definitely not type-S so I am not sure where this talk of a Type-S MZ-S1 originated. Has anyone ever seen an S1 with other than Type-R on the plastics, rather than some possible misprint in a manual?

I don't know why but I thought I would be a tad more interested and excited than I am. Perhaps it's because the glue which holds the 3v power flap rubber in place stuck to the display connector better and tore a chunk of rubber off! A warning to anyone opening theirs - you may do the same and damage the 3v inlet flap.

I recommend you buy it seems there are two versions of it out there so the latter version. A quick listening should help you decide. I have both the 505 and S1 and the S1 sounds much better. I remember in the manual that I received it stated it had Type-S. It could be documentation errata but why the great sound? The 505 drive is noisy the S1 drive is not.

Yep,

Check. The 2677-202GA is the same chip as the 505.

Could be doc errata but then again it could not lets think of the chances of this:

http://www.docs.sony.com/release/MZS1.pdf 3-239-099-13(1) 2002 this doc says TYPE-R

http://pdf.crse.com/manuals/3239099411.pdf 3-239-099-41(1) 2003 note the later doc rev. and later copyright year. This doc says TYPE-S.

From listening some S1s sound much better than 505. I can mostly tell handhelds which are type-r and which are type-s. Type-r can sound crackily on lp2. Decks on the other hand are a different matter.

This wasn't a straight copy and paste when they upped the doc rev. The doc. was updated for some reason to reflect new information. Well this is why I think some S1s could be TYPE-S.

Very odd. Sony did not normally keep quiet about a 'substantial' change to a unit like this. For example, the R500 became the R501 when Type-R was added, also the R700 being called the R701 with Type-R support (although on both occasions cases were also changed, not just the DSP chip). I would have expected an MZ-S2 at the least if there had been a skip from Type-R to Type-S.

I would love to get hold of evidence of the change other than just the documentation, which is why I asked about an S1 with changed casing decals or legends. The second document linked to does indeed mention Type-S on page 66, but no mention on page 20 where I would have expected to see it also, when Type-R is first mentioned.
