Oh man! You certainly have some goodies stashed somewhere! tongue.gif
Yes, those early Sony models can still beat the daylights of some of the current players! Thank God, mine can play any CDR thrown to it without any fuss! Will you put this up in the 'old school' thread? biggrin.gif I simply love 'old stuffs' tongue.gif

It reminds me I've still got a DVP-S7700 stored away in the box for some years now. Silly me I've never used it as a CD transport as I already have a dedicated CD transport. I may do that one of these days. The video quality still beats many current DVD players, just that its not able to read recordable DVD discs.

Y.C.,
Yes.. Sansui had bungkus a(long) while back. Too bad.. they make such nice hifi components.. and their black coloured design are always unique.
I guess all good things have got to come to an end... just like Technics here, except Technics is some what still alive in their homeland, Japan.

Oh ya.. that was the flaship and reference of all DVD players during their hay day.. I did count my blessings of having acquired such a great product tongue.gif and to certain extend, it still is! brows.gif

I'd say that Sansui partnered with the T-Amp will be the "Best Bang per buck" CD based system! thumbup.gif Nice to know you have a 'little' discount on bulk buying.. wink.gif Good for you!(and your friends too!) Wonder what other things you might have poisoned your friends too... hahahaha laugh.gif

Yes.. you need a pretty fine tip iron to work with SMDs.. I did mentioned earlier I just have this 'lil soldering iron I bought from Sim Lim Tower, SG which would be splendid for this type of work. Best of all it works on 12VDC.Well i tried in on DC, could have work with AC too! laugh.gif
Having a variable PSU, one would be able to adjust the heat.. wink.gif
Ok.. I will take the lead in the SMDs replacement.. have to add that to my TATDL (T-Amp To Do List) tongue.gif

So, you've just notice a new line in my signature... wink.gif Thought no one noticed that! biggrin.gif

I was thinking of making one for the office use... but I remembered one reviewer was commenting or rather warning about the Sonic Impact amp if it were to be played in the office, NOT much work will be done! laugh.gif And I will have to agree! I have difficulty doing anything else at home too! blush.gif



QUOTE(Y.C. @ Sep 11 2008, 09:57 PM)
Bro Jazzy,

I believe Sansui Electric Co Ltd has already ‘bungkus’ for quite some time, hence not much info could be found on its products.

The Sony DVP-S7000 that both you and bsl555 owned is built like a tank and in fact beyond reach of many ordinary folks (me included) when it was first launched in yesteryears. It sure is one hell of CD transport and when paired with a decent audio D-A-C, not many midprice CD players let alone the entry level Sansui CD-X310 could come close to its sonic prowess.

My colleague, friend and I went to KLIAV Show 08 together where one of us was ogling at amp, another at cdp whereas the other at both cdp + amp (all affordable priced ones); I managed to convince them to try out the T-amp at RM55 and one thing led to another; now we bought the Sansui CDP to complete our inexpensive but great-sounding systems. Since we bought 3 units, the seller relented to just a little discount for our purchase.

I have yet to replace any single SMD with capacitor/resistor and actually wanted to hear out / follow the leader of either your goodself or bro Xtorm. I may also need to replace tip of my red Hakko soldering iron with a finer tip before I could solder caps/resistors in place of SMDs. sweat.gif


Added on September 11, 2008, 10:03 pmHeheh, I just saw your newly added signature of "Home is where T-amp is".

I say make one unit for the office as well; I brought mine to office today and is having a field day here ....  brows.gif

xtorm,
you haven't recovered yet? tongue.gif U better do something about it, buddy!

Like I mentioned it earlier.. your T-Amp is awfully crowded! laugh.gif

Yeah.. that S7000 is one hell of a machine! thumbup.gif

Hey, don't be so modest la.. you're the one that lead us to this T-Amp frenzy! I bought FOUR! doh.gif laugh.gif

I shall wait for your input caps removal report! wink.gif

QUOTE(xtorm @ Sep 11 2008, 10:24 PM)
hahaha, i was thinking of doing it just now, i mean removing the cap tongue.gif but my fever kinda stick with me still!! felt dizzy when i was in the car listening, so i gave up the idea...
tank cap? haha 3 x 3300uf and 2 x 10000uf, and thts for 2 amp, so i think...still not enough ;P i got some 1000uf laying around, will try to fit it in rclxm9.gif
wow tht dvd player is tht good eh? i saw 1 sold at hifi4sale few days back....
hahaha, im no leader, there is no leader here, compare to youself and bro jazzy, im pretty much newbie, not forgetting ongbs too biggrin.gif the gadget master flex.gif  rclxms.gif

xtorm,
So do I! With any luck if there are, will keep you and the gang posted wink.gif

Y.C.,
Eh me? No lah... Lead into something noproblemo.. leader is a different ball game altogether tongue.gif
I have not done any MAJOR soldering job other than the caps and inductors replacements on the T-Amps. The SMDs replacement will be a challenge.. Have to look at the schematics again...
BTW, xtorm, you did replaced some of the SMD resistors right? How was the outcome? I mean the improvements?

Oh yeah.. I bought four T-Amps! laugh.gif Two will be my final configuration(bi-amping). One is for junior and one spare for "R&D" and other miscellaneous 'jobs' wink.gif

You have a Roksan Caspian CDP? Wow.. real solid unit that one! With a 'solid' price wink.gif Last I heard was in a hifi shop auditioning some speakers with a friend. It's a Roksan but dunno which model... tongue.gif But certainly looks like the Caspian M series...




QUOTE(xtorm @ Sep 12 2008, 12:42 AM)
i would love to know where to get some nice parts for our t-amp....biggrin.gif

Jazzy,

Cool bro, you really are a leader we could count on.  thumbup.gif And you bought FOUR T-amps yourself?
ekool, welcome aboard TAFC again.

......

I had always believe that CDPs need at least 100 – 200 hours to run-in as in the case of my Roksan Caspian m-series-1 which only sounds right (at least to my ears) after some 300 over hours of playing music proper. 
xtorm, PM answered, kindly check.

xtorm,
duly noted! I am going to do that next prior bi-amping wink.gif
say, when are u going to pick up your stuffs from Y.C?

Any balance unit from batch 3?tongue.gif

QUOTE(xtorm @ Sep 12 2008, 10:19 AM)
yep, i change the input resistor, imaging is much better and not as harsh, more details too, but i did it togather with the direct power supply line to the chip

i beleive the gain is atleast 99.9% accurate now in both channel as im using 1% resistor which was hand picked tongue.gif hahaha all value 100% same in my meter. compare to the original which range from 19.6x-19.8x

Y.C.,
Your schedules must be hectic ya...? tongue.gif

Yep I do agree. xtorm you better do something about your perpertual fever! Extended fever is NOT a good sign... shakehead.gif

Does the Sansui have digital out? optical/coax?






QUOTE(Y.C. @ Sep 12 2008, 05:31 PM)
Xtorm,

Did you count the physical quantity of items received against what was written on the reverse side of envelope? Any mistake from your original order?

Since you have received those items, most of us here in this thread expect you to report back the difference in sound of your T-amp after each component change, fair deal?  biggrin.gif

Joke aside, you need to ensure your fever go away for goodnod.gif
Ongbs,

Yes, the Sansui CD-X310 cdp could play CDRs, no problem with that.  laugh.gif
ekool,

Great posting!  thumbup.gif

There's a detailed write up on delta sigma converter here: tongue.gif

An Introduction to Delta Sigma Converters

In a nutshell: A delta sigma ADC or DAC always consists of a delta sigma modulator which produces the bitstream and a low pass filter.
I think the DAC is made by Cirrus Logic.

Should sounds pretty good wink.gif

I am eyeing another CDP... brows.gif Hope to check it out tomorrow... the seller in Bandar Botanic, Klang shocking.gif

Nahh.. scrap the Sansui biggrin.gif

Nahh, scrap that CDP too! .. the seller sold it to someone else after I tried to reconfirm tomorrow's appointment! Which was agreed earlier on! How can this happened? vmad.gif Some people are just unethical.. vmad.gif vmad.gif

On the bright side,its a darn old CDP anyway.. better off with a 'newer' model as advised by Y.C. biggrin.gif
