Yes, same master but kept it in 24bit and applied dither. 192 to 48 and 176 to 44.

Ooh the yggyrag, that will be a popular station!! Plus Glenn can still rum the Woo amp se for some added flavor.

Just bringing the Stax rig. Woo is staying home, doesn't want to get beat up by the big bully Rok after school.

It's probably more like it doesn't like the competition for who makes the most heat…

Hi gents,
Good news on the Soldering front inside the OPPO. I could only do the small transformer wires and large toroidal leads with the silver solder I have. My home iron isn't suitable for fine work and my eyes are starting to go....

IPA cleaned the female crimps rub Down 2000 grit inside and soldered the wires on rather than the mechanical grip.
A pain to do as after soldering.. IPA again to get the flux off and some Deoxit. . 14 power leads later.

A light rub of 2000 grit on the board male pins
Make sure they are flat and smooth...

Then a quick electrocution tripping the fuse board and making me see stars...
board was live when I put the iron on...idiot..didn't turn it off again...
Oh soldered the earth lead and crimp washer. Tinned the whole thing to get more surface area touching it..

I am a happy bunny.. more detail off this extra work. Even though it had been deoxited 2 weeks ago. Not a subtle increase either.

The CILCLEAR better come this week, was dispatched Friday now it's in stock.

Nice to see all these efforts work.. Silclear the last piece of the experiment ... But hard soldering all connections would solve this. I am sure most high end gear has this unless modular.

If I did hard solder I'd have to totally remove all boards as you would get dry joints under the pins...

Bigger and more detailed sound.. bloody lovely...
A smaller WW chroma AB even with the dirt on the gold plating didn't seem to add much post intona.
The INTONA is staying with The IFI IPURIFIER 2.

I had an old Oppo Jaguar sat in a garage..
This is now race tuned to what I had before just magic..

So I am now positive that as people find the best cables, amps and DAC'S there is plenty potential locked up inside because of its never touched,even bought in parts. Nothing is perfect unless hard soldered but you can get to the point were it sounds like it is....

Thanks guys for pushing me to try new things and experiment.
...
CILCLEAR and maybe bundle the cables and shield them.. Do some of the other Coris OPPO heat and RFI shields...

I am so happy hehe hehe.....




I won't go into details.... but a home made Ultrasonicesque IPA bath in a glass dish got all the dirt off the screw threads... All fun...

Cheers
Dave

Got the ifi purifier 2 before the ifi usb power and the sound is clean clean clean! Very impressed.

I should mention usb cable is wireworld starlight silver clad throughout.

Some experiments I did with ERS paper, with wonderful results:

Thanks colt,I thought as the other poster said he put copper on IC'S.
Blocking RFI you would drain that to earth via a cable. EMI is a bit like squishing the magnetic wave at the barrier and drain. (Sorry for the simplistic answer it's all I know)
So the paper must be a RFI shield?
Correct me if I am wrong....I know little..
You might kill 2 birds with one stone..
The copper foil cut and placed on top of IC's but the non sticky side down.
Then use TIM thermal interface material.The silver stuff for computer heatsinks.
Use the copper as a heat sink and RFI shield combined...Just a thought..

That sounds like an interesting bit of tweaking.
 
RF is weird, in a lot of ways.
But it seems to me that since the chips are inside a case that it might be more of the 'stray' RF from the rest of the circuit inside the case rather than from 'external' sources as being the culprit.
 
I need to read your full report to see if any of the benefits resemble other tweaks I've tried.
 
Cool stuff…

The only caution I'd add to your 'sandwich' would be to NOT let the silver thermal paste ooze out and short out the pins beneath.
That would be bad…

Just an initial report...just got the Silclear silver... Headphone pins 3 pin IEC uk 3 pin plug... positive so far no negatives. Going for whole chain and power. Also all internal connections this weekend.. Wish me luck...

 

[Middy]

It is messy stuff both TIM sand the Mapleshade Cilclear. Very nervous about creating shorts.So no more than 3/4 down a pin...very thin smear.i predope it first with a tiny amount...

Cheers JJ
Keep smiling brother...

[johnjen]

Also consider using the ever so smallest amount of silclear on the fuse to the fuse holder where they make contact.
And talk about the possibility of a short…

 
Tread carefully and consider worse case possibilities.
 
BUT having performed this tweak myself it did make a change and I'd term it an improvement.

The Schiit equipement/cover is supposed to shield against external EMI/RFI from what I've heard, but I also heard electronic components can generate the stuff themselves, inside the equipment.

Yes, that would be my intuitions as well. Moreover, I would expect this tweak to help more with DS chips, which operate in faster MHz ranges, than with R2R chips which stay in the slower kHz range.

Was looking for a better solution to Q tips..cotton buds.. We do not use these in work as we has industrial controlled washes. ESD and non shedding...clean room quality. Handy for cleaning and applying...

Another handy tool. ESD safe...
