I have the passive version of this speaker, Gerbrand van Veen has invited me several times to come but i'm afread that if i hear his active version i have to buy these and this is taking to much
of my wallet after the UCD amplifier project.

Wich was by the way the reason that i had to take another mod round on my CD67 to take full advantage of this amplfier.

I like what i see inside this SA8200 thats for sure but knowing you
for a couple of thousend sentences in this tread, i'm sure you wil kick the hell out of this machine

Yeah, this audio-virus takes up plenty of financial resources . But it's better than buying a €10.000 machine off the shelves and then brag how good it sounds. At least we created something ourselves . I'm confident my set kicks most expensive so called high-end stuff's butt. I thought about taking my player under my arm to one of the hifi-shows and see if I can get some salesman crazy enough to hook it up in a demo-room .

I have two Tent shunt regulators sitting here that I still have to try, but I haven't had any time for that.

Are they +/-15v or are you going to fiddle them to +/-12V?

I'd love to hear how you get on as I'm thinking of trying this myself. The Audiocom ones are cheaper on eBay though. The Tent X02 and XO supply has transformed (no pun intented) my CD67SE so I have faith in Guido.

What I love about this thread is that whatever I search on in this website, this thread always pops up somewhere in the results. I think you guys have mentioned (and inserted into a CD63) every device known to mankind

Evening all.

I decided to get my external psu back into the workshop this evening as there was excessive noise on the cd's output. I added a star earth point and wired it to house earth. This reduced the noise to an acceptable level (more to do soon) but had the happy side effect of doubling the perceived improvement of the mod. I had to trawl through 5 or 6 CDs revelling in the awesome bass and beguiling, detailed sound.

The braided wire is connected to the earth pin of the IEC socket. You can see I added ferrites to the earth leads to minimise any HF noise polluting the earth (who knows!?)

Spurred on by not breaking anything, but quite the opposite, I decided to add another transformer (15v@1a x2 toroid) and psu (schottkies, 15,000uF Rubycon, 1uF polyester). This feeds my 5v reg board (was fed from 20v in the player). (The 5v board has 1000uF Black Gate and then 33uF Pana FC after each reg (analogue dac/decoder, digital dac/decoder, and other 5v (err, what is it??) same as before)

I also popped in a red neon I had lying around, to warn me that it's on, as there was no other indication (apart from a quiet hummm close-up).

I've only had a quick listen since this mod but listening to Dire Straits, Dire Straits the result is surely a good imrovement. Mark Knopfler's voice has never had this kind of fully develpoped character before. Each part is easy to follow and well rounded. Yet again, upgrading power supplies in this thing proves to work!

(I can hear a high pitched whine now, which probably wasn't there at switch on - perhaps something is marginally stable or something??)

After some SMD surgery they are now +/-12V . I'm going to put some three-pin sockets on the PCB so I can swap regulators easily. I'll let you know what I find, but it may take some time .


Simon,
Nice work, seems the separate PSU's really pays off. You still have room in there for a lot more trannys . I really should look into that star-earth-point thing....

I too have thought of doing this. Make some expensive gear look over priced. I am thinking of contacting an audio magazine and seeing if they fancy doing an article on modded players.

Good stuff mate. Only one thing to pull you up on NEON = noisy

I would change it for an LED.

Yeh I did wonder but it's far easier to use a neon and it shows that mains is in there. An LED would only be lit if the power had gone through a tx etc. (unless I did a dodgy connection straight through a resistor and diode)..

I am toying with the idea of having an LED (purple!) for each power rail

You big gay

Looks good mate, and is pushing me towards building a spearate PSU for my 5V reg board (when my cdp is running again )
