Default 47labs Gaincard: new circuit. More info available?

Gaincard with new circuit topology

Junji Kimura delivers again! He came to a new circuit topology of Gaincard which resulted in even more open sound with a touch of sweetness in it. The new orders are all delivered with the new circuitry.

We offer the modification for those who already have the old version Gaincard for $200 + shipping. Please contact SAKURA SYSTEMS for details.
... copied from the www.sakurasystems.com site.

I could not find some info, up to now, what the changes are.

Snubber?

T-network is not very likely, as the Gaincard is noninverted and nonbuffered.

Franz

I would speculate that they finally got rid of Zobel

Well, if it says topology, that would imply more than removing a couple of components.
Of course, what they imply and what is real are two different things. Maybe they changed the brand of bypass caps or something.
$200 to tell you how to remove the Zobel?

They've probably got their hands on some nice blackgate capacitors and caddok resistors used them instead.

You guys don't accually think they made some minorchanges just to get more money out of the consumers??????


anyway, since i'm posting so:
whats the difference between mkp-branded capacitors and mpt-branded?
