Default Stock NAD 3020i Upgrade path.

I still have, and use daily, my 3020i but Im getting the upgrade bug using my source is a SACD player.

After some lurking and research I'm looking to tack the upgrade but I'd appreciate knowing where to start, or at least which projects to tackle for the for the greatest benefit.

Likewise I'd be all to pleased to learn what upgrades would be a waste of time!

I'm lookng at the following individual projects:

Pre-amp regulated power supply diodes

Power-amp unreglated power supply diodes

Signal capacitors

Signal resistors

Modify circuit design to eliminate tone and/or balance controls

TIA for any help I can get.

If you search the forum for '3020' you will find some recent stuff.

Regards, Eric.

Default I did 'search' but it wasn't any help.

I got a few threads, one recent that was long but in it the circuit design was discussed and the op-amps were evatuated.

That was all got and I was suprised.

I am looking for something more specific, and helpfull opinions.
