Major updates and corrections to my original post regarding the SRM-D10 II charging and playing when using the provided charger instead of my generic 5V charger.

I recently got a new X9000 and there was (and still is) no channel imbalance at all...

usually in stax amplifiers, rca bypass it is just a wire unshielded connected between the two rca´s

I would never use RCA bypass not in any amplifier

I would never use RCA bypass not in any amplifier

I find it really convenient

How. do you like the X9000 with the Sirius amp?

Can't say as I sold my SIRIUS a while ago since I prefer the sound of tube amps. I do like it a lot with my SRPP modified ANTARES amp!
But knowing how my SR-009 sounded with the SIRIUS I'll assume it would sound nice!

Indeed, the Sirius is a very nice amp, but the Polaris seems to be an ideal match to the X9000. There are some posts in a german forum.
Polaris
I also prefer tube sound and own an Alpha Centauri.

I had the POLARIS here before it was even officially offered - an amazing amp, better than any other transistor Andreas has ever built. Head-to-head with the KGSSHV CARBON (we made several comparison sessions). Sounds amazing with the X9000 indeed!

PS: POLARIS is a bit larger, it just looks so much larger the way I photographed it…

You have alpha centauri with x9000?

 

[sillie]

No, I have a SR-007MK1.

 

[alota]

No, I have a SR-007MK1.

So i imagine that alpha centauri has power for 007...

Been taking a bit of a break and been flat out with Youtube but finally have a few weeks put aside to work on the 2.0 platform. I have been going back and forth with Lundahl for a couple of months and I have a new transformer design which just arrived for testing, the first that is specifically designed specifically for STAX use as far as I know. Will have some results shortly and will feed back to Lundahl also.

The DC-DC bias supply is going through many revisions also, though I have had no issues whatsoever with the first version. Will share changes soon…

Still contemplating input protection for the transformers to prevent over driving them, I don’t like introducing stuff into the signal path personally…

What did LNDAHL make differently with this new design of transformers? They look bulkier and larger. Different core material? Different winding structure to reduce secondary capacities?

Core is much larger, not sure if it’s large enough to beat 2 x 1630PP teamed up yet but the following info is what I have so far before testing…

Ratio is 18,5 + 18,5 : 1+1+1+1, this transformer is based off the LL1689 transformer platform but modified.
