You have 22 voltage regulators on the audio board AND you are using Paul hynes voltage regulators on all 22 regulators?

Do you have any bdp9 porn you would like to share with us?

The sabre 9038 pro is not. It carries an additional 5v input, so you could not directly perform a drop in replacement like you could when going from 9018 to 9028. I read elsewhere that the 9028 is sonically an improvement, but it does not carry a night and day difference between the two.


Understood, it is not compatible then....., thanks for clarifying the point.

I remembered reading this, ( In the link i attached ) apologies :


Clearly we see the ESS Sabre reference DACs in the Sonica DAC (ES9038Pro) and BDP-105 (ES9018) perform extremely well...

Not certain which ess chips the bdp 105 utilizes - the 9018 or the 9028 (pretty certain it is the former since it is just a revision of the bdp-95). The bdp 105 was released before the incarnation of the ess 9038 pro but I believe it was around during the ess 9028 run. It may be possible that later versions of the bdp 105 utilized the 9038 pro. But then oppo would not call it the bdp 105 anymore.

This is speculation on my part but I am pretty certain that is the case, unless someone could prove otherwise.

ESR is better on the RIGHT Panasonic caps. Not all the same.

Lelon caps are good too.

Paul Hynes technology. I designed the regulators.

Steve - did you replace all the regulators on the audio board (22 of them?) with your regulators? Are they running in shunt or serial or both? I am still thinking of going with tentlabs regulators for the 3.3v and burson for the 1.2v regulators.

I use Paul hynes ps and regulators on my turntables.

Also, would you mind sharing which caps you replaced on the audio board with your solution of caps?

I've been meaning to upgrade my bdp 95 for quite some time, but other projects have taken precident.

These regulators are serial, some with small pass FETs and some with large pass FETs on heatsinks. They have all been speeded-up, except the analog ones. For Digital, you need fast regulation.

They are not "replaced". It is my product. My mix of decoupling caps is one of my trade secrets, sorry. Maybe if someone buys my component business, they will share this, or after I retire in a few years.

Default replacing stock clock in Cambridge 851c

I too am interested in replacing my stock clock in my Cambridge Azur 851c to a NewClass D Neutrino Super clock and while the instructions from the manufacturer are simple to follow, I don't have a schematic for the player (it is still in production). I didn't have any problem finding the power for the clock, but I am having a problem finding the two caps that I need to remove in order to install the clock. I have attached photo of the board below with the hope that someone can help me identify the right caps to remove. Since they are surface mount devices, I don't want to make a mistake-- replacing them would be difficult. Thanks in advance to anyone who can help.
