I replaced the Lpad with 50-75 pi-pad. I used caddock on shunt and shinkoh on series. So far so good. What ive noticed is that the sound is much more natural and coherent compared to the Lpad. It seems that vocals are much more clearer. I like the improvement.

Waiting for jarek to be able to get back on making resistors. I would like to try his flagship resistors for the pi pad.

Hi Tubo,

Have you ever tried Allen Bradley Carbon Comp Resistors?
Cheap and very good

Regards,
Rudy

Hi there!

I see this thread is still going strong, so I though I'd share a couple of things here... I wrote about my experiments a couple of years ago (you can read it here if you like
The CD Transport).

The c916 cap value has changed though. After extensive listening/testing, I've settled for 220uf/100V Elna Cerafine. A 47uf cap just sucks in comparison and the added voltage, although not technically needed, does sound clearly better. And the cap would be the Cerafine, not the Simlic II. With the Cerafine 220uF/100V the sound transformed from good to wonderful.

Secondly: Make that transformer 120VA (I have Hammond 120VA / 266P24) - much better bass slam and soundstaging that the 96VA. Also tried a 120VA toroidal. The iron core Hammond transformer was quite a bit better.

Two things you guys should definately try. But of course all these findings are valid in my system, my power cords, cables etc, YMMV.

My 2 cents.

Cheers!
Jugi

Hi Rudy,

I have not tried allen bradley but i will try some rikens on series and caddocks on shunt.
which other kind of resistors have you compared the allen bradleys with?

I used these resistors based on Jarek's recommendations.

All the best,
tubo

Currently a Caddock MK132 in Shunt and a TX2575 Texas Components in series.
But cannot compare well because the Shiga mounted in a closet so cannot switch fast.
My first impression with the Allen Bradley in series sounds a little warmer.
But a new Vicol Shiga order have done and go build everything again this winter.

To be continued …

Regards,
Rudy

Rudy,

Jarek mentioned that the vishays in series sucks the dynamics out of the music. Can you confirm this? I mainly stayed away from the vishay due to this but i have not tried it.

I can not currently well testing, but have briefly looked up and Erik has also tested this resistance.

Look here #6904 : Finally, an affordable CD Transport: the Shigaclone story

Must say this Vishay sounds pretty good as series resistance.
As I've mentioned earlier I cannot quickly switch between these resistors, to give a clear and honest advice.

Regards,
Rudy

I recently fried a chip in the progress of modification...seen that ..done that..we have all been there...

Anyway decided all my experience should go into the new PiTbull board and it should be modulair..

This is what I came up with...specced with non polair Blackgate in super E config and Audionote silver wired throughout...goldplated plugs etc etc

So know it is easy to have a quick listen on my test-cd-transport-board....

Question for the technical brains and clockbelievers (not or) among us.

How important is a decent clock in a DAC when you have a decent clock in your transport...is it so that the DAC clock is only operative when a connection is made after which it is shut down..also the master slave bit is a bit difficult for me to get right.....links are also welcome.....

Is the Daddy of all Caps indeed the right choice for implementation on the strange C906 position (Laser tracking System) 0,01 uF

uhhhhh....YESSSSSSSS Full in Disbelieve

First the candidates back on the cd-transport-test-board.
This time only three candidates...looser-winner- challenger and also 3 pair of ears at the session.



1. The Original 0.01uF elco
2. The Duelund Alexander
3. The Duelund Cast.

Again the difference between the Original and the Alexander was evident...less raw, more music..so the same notes...

Than high expectations will the Cast top this a little bit....squeeze some extras out of the situation......well not exactly a little bit .....more like implementing a super clock....one of the listeners shouted "no brainer"....

In the end you try to figure out the logic in this affaire.....
First you come to the conclusion that the technical difference between an elco and cap can be responsible for a difference ...but a difference between caps.......well I do not care actually maybe less correction of the laser who knows..
All I say is yessss....and will leave it there......

Cheers for the plug-in possibilities and my guts to buy it in the first place...

Sound notes for the Duelund Cast:
More timbre (wood sounds wonderful)
Highs have more support and body
More quietness and details

Indeed a No Brainer...............for the one who wants to go one leap
