It is nowhere near as nice a piece of work as the delrin one in your photo above though...

I would like the skills to make that!

Today I made the preparations for the three clocks.
I made use of my own Shiga testboard...the Mini PiTbull is too Mini for this

I use miniature plugs so I can switch quite easy....keep you informed...

Forgot to explain:

The clocks are mounted around the transport with :

On the left: Trichord 4 with their own PSU
On the top: Tent with their own PSU
On the right: Dexa with their own PSU

They all enjoy the same main filtering and Bybees...

Looking forward to your observations Erik.

I want to add an AES output to my transport. I have found this drawing for a circuit and would like to know if it will work.

I also found several drawings with just a transformer between the two but it only seems to work the other way AES-->S/PDIF.

This is more for experimentation than anything else.

At the last minute a fourth clock will also be tested...

The EZ Ultimate from DIY supply...

http://www.diyhifisupply.com/node/583


I will not test the original resonator or the citizen..I have listened quite a few evenings to both of them......they both sound nice but that is (for me....in my set up....to my ears...blah blah blah) about it.

Uncle Leon,

I have asked my audiobuddy to give your pi-pad sugestion a try
So he did put an extra 100 ohm (I think he uses Allen Bradleys) as shunt in.

He mailed me enthousiastically his music became "cleaner" more " pin point" and "more resolution" those were his exact words....

Cannot wait to try it out myself now....since I think of him as a very good observer

Too bad I hadn't known that you would be interested when I was sending you the stuff for testing. I do have a wood-mod "demo" capacitor pair, i.e. both the same type but one wood-modded and the other one original. I don't really keep any modded caps in stock, I only do the mod on request as it's a lot of work, but I can certainly mod your caps for you if you like.

Usually adding components that are not necessary only makes things worse so I am amazed that my resistor actually improved the sound lol... I am certainly glad to hear he liked it, even in this sub-optimal scenario - but if he thought adding one on top of an Allen-Bradleys was such a noticeable improvement, then he will be positively blown away when both are installed properly


Now, on an unrelated note - I have just done some transformer comparisons. I compared my custom 300VA toroid against a 60VA R-core, and... the R-core was clearly better. The sound was cleaner with improved detail and definition.
As the toroid is a massively over-spec'd 300VA audio grade unit with all the possible bells and whistles, I think it can be safely assumed from this comparison that no toroid can conceivably beat an R-core in a Shigaclone. Of course, this does not mean that R-cores are the best possible choice, as other trafo types (such as the Hammonds recommended by Peter) could turn out to be even better.

Uncle Leon, I do not know if you got me right the first time but my friend went from an Allen Bradley 300/100 combo to your pi suggestion so only adding another 100 Allen Bradley to the other two Bradleys...

I did not lend "your stuff" to him

Btw received the naked vishays today 100 was okay but a 390 instead of 330 ohm grrrrrrrrr
