back on the subject of power supplies - a couple of weeks ago i finally decided to split the +5v supply at the point in the pic below which is from a previous post - hope the owner doesn't mind me using it.
Click the image to open in full size.

I'm aware that many peoples experience is that it makes no difference but I've almost always found that seperating supplies like this makes a great difference to sound quality - anyway, i had to give it a go to satisfy my own curiosity.

i injected a fresh +5v supply from an Audiocom Super Reg 3 which i acquired recently. I also replaced C954 with a decent 10uF BG (it is actually across the +5v supply) and sat back ................................. I have to say that while there was an improvement in clarity - it also seemed to muddy the waters a bit in the lower freqs! - not good.

I then decided to try one of these instead - MURATA POWER SOLUTIONS|7805SR-C|SWITCHING REGULATOR | Farnell United Kingdom

I found out about these babies from AoS and was pretty impressed by them - in it went and I sat back again ...................................... much much better!! - the same clarity but without muddying up the bass - very happy - and cheap too!

Certainly I reckon it is worth seperating that +5v supply - but the results do seem to be dependant on the reg used.

Peter,

do you still have the new clock in place and do you still think its an improvement over the citizen on its own?

I've had the hardware for the Shingaclone for a while just sitting protected in a drawer with the new crystal and caps. No mods or work have been done to the hardware in any way. It sits as it was shipped to me from Algar.

In that time I've acquired a Sony C2000ES and Denon DCD-F101 that I'm using in my console.

I have PD's NOS USB DAC and his phono stage that I'm using as alternate sources.

So, I'm willing to offer up my hardware to anyone who is interested. I'm just looking to recover my cost so the funds can be applied to my AudioSector F5 builds.

PM me if your interested and I'll send you the cost I have incurred and we can go from there.

I still have it and I'm not tempted to change anything. The transport and modified NOS DAC make a very satisfying combo.

I've collected parts for your scheme of post #3786.
Could you suggest where do I have to connect this point on the board?

Hello Peter how do you use the shigaraki clone right now

Default Offboard mounting

When I bought a spare mechanism, it came with a small pcb just containing an end of travel limit switch and a connection socket.


I took mine off and replaced it with the main standard board and forgot about it. Then I saw somewhere an image of the main board separated from the mechanism and strung out like a trampoline to one side.

I did not see any comments as to whether this has any positive effects, (replacing the main board by a much lighter one - not the trampoline) but seen as how the shigaclone is so sensitive to mechanical mounting I would not be surprised.

Anybody like to comment? I am too lazy to take it all apart and remount it just to try.

The advice given waaaay back in the thread was that it was beneficial to separate the PCB from the mech. In my case one is jut mounted above the other and I added a little bit of wire to "extend" the reach of the bit of plastic on the mech that hits the limit switch.

I think the theory was that you were removing the motors from the pcb and they were a contributor to noise and vibration. Does it make a big difference? Probably not huge, but its all incremental I suppose. I don't think Peter does it anymore.

I use it as described here: Finally, an affordable CD Transport: the Shigaclone story

Recently I added clocked output and I quite enjoy it: Finally, an affordable CD Transport: the Shigaclone story

I was never separating motors from main board; too much hassle. Besides, I do have "backup" transport with such feature

Great.

I've found some RC-EZ31 units at the source.ca (you've got to call and place an order online, then have them deliver it to the closes location for pickup.)

JVC portable CD boombox | Portable Stereos | TheSource.ca

I've ordered 2x. Can't wait to destroy them. LOL.
