Well, the SAW actually.

I have set it up it right now that I can compare the two easily and I will be able to do the comparison for other people in the room over the near future, and get more feedback.

I only agree with you (I have the same opinion) that SAW oscillator give a more precise/accurate sound. More than an Crystek, I mean.
I still want (waiting for) to hear from someone who used an SAW saying that it were bad experience...

But Joe, it may be in place 3 SAWs... For DAC, 25Mhz, 27Mhz (54/2). I`m excited to see what it may happen with an 27Mhz in the right place...

Hi Samy.
I have understood that shorting the capacitors in the output stage there is an improvement, as you run a curtain of impairment.
I do not make any changes, do not quite understand this.
Some argue that just have to be shorted and other metal capacitors should be placed 3 to 4 MF, Jantzen type audio, Mundorf, etc..
always on the output stage.
When you can expand a little more information I will perform the test and post the results.

Hi Julio
You may know that the 95 model it not have caps on outputs (is DC coupled).
About many tantalum caps, those are used to decouple power rails for some chips involved in signal processing.

Hello,
My 93 NXE is already super modified.
Full power linear in OCXO clocks, OS CON and Nichicon capacitor on the motherboard.
The only thing I have not changed is the drive.
I would like to improve.
If it is possible.

I have a 93. If I just change out the power supply to a good linear power supply how big of an improvement in Video and Audio should I expect if I connect it to a sound processor with an HDMI cable?

I want to switch off the audio-board in OPPO-95.
Because without fun Oppo gets hot after 1-2 hours of using.
Clued some 478 socket radiator (of course), drilled more holes in the bottom but it's not enough.

I use OPPO mainly as a transport, so I want to switch off the Rotel trafo with 110/220v switch on the rear panel.

But what to do with emulating signal (OVP-TEST)?
I tried OPPO without upper board, and it played CDs normally, but I'm not sure in full functionality (BR etc).
