RME ADI-8 Pro Mod?

I was happy with my RME ADI-8 Pro for getting audio in and out of a
Digi 001 setup @ 44K untill I did an unscientific comparison of the
Kurzweil Rumour's A/D vs the RME's.

I prefered the Kurzweil's conversion.

I've heard of a modification out there for the RME. Anyone have this
work done? Pleasing results?

Thanks for any thoughts, Fingerz

Jim at Audio Upgrades has done a lot of things to the RME, including
using better op-amps and capacitors in them. I have only tried bypassing
some of the input capacitors but found that to be a definite improvement.

Based on some work using Kurt A's JW mod'd ADI-8 Pro DS I'd say Jim's
work is well worth the money.

Thanks folks.

You'd think RME would take note of these 3rd party upgrades and make
the product as good as it could be from the outset.

I wonder if the mod to the RME would have the unit yielding superior
results to the Kurzweil's conversion...?
Hmmm.....

Maybe, but I doubt it!

You might want to watch out for that. Most modern A/D chip's inputs are
voltage referenced to 1/2 the power supply, at 2.5 volts. Blocking caps
are needed to keep this bias out of the input connectors and then out
of the device that's feeding it. Running 2.5 volts up the ass of a mic
pre may not cause a problem, but if it's direct coupled, or if the
coupling caps are reversed, it could be one.

The mods include Wima MKP-2 250 polyprop film cap bypasses on the
Panasonic FM caps which are replaced. The opamps are LM6172's.

Have fun, remember, they don't work if you let the smoke out!

RME Adi-8Pro is a difficult item. Modifications are not easy because the
pads are very thin and narrow. If you are not very skilled in soldering, be
aware of that.

For Scott: did you really bypass the 2 input caps for each channel? I gotta
try that...

That would radically increase the cost. Remember, this stuff is built to
a price point.

I don't know. And there are some converters out there that are probably
superior to the Kurzweil too.

Yes, since it's _always_ being used with a preamp that has output blocking
caps anyway. No reason to put more caps in series.

Go out and listen to the Prism stuff, or the higher grade Lavry gear.
