I would assume yes...but I sure want to take one apart. Don't think we will ever know what is in the black encased modules. Just received a 9" 2mm T handle hex key for this very purpose.

Does somebody knows the Imput impedance of the LA90D ? Strange that is nowhere to be found, it is an important criteria....

The LA90 had 20kΩ Zi, the LA90D is probably similar.

Not so good...I was expecting at least 40/50 KOhms....

Is there a fuse in the device (or in the power supply) ? I can't see any ...
That would be balanced I think. I believe I saw John chime in somewhere that that is what he recalled but he was not 100% sure. If putting some kind of adapter or unbalanced cable it would probably be half that so 10K?
Sale ongoing again...12% off list. At least at ShenzhenAudio for a few more days
Done. Two more on their way.

Do you need a special preamplifier to run 4 blocs, or ?
Is something like the SPL 2control up to the task ?
I would be also interested to run 4 blocs as my LS have bi-wiring = 1 bloc for each voice of each LS

I have a pretty elaborate set up and run each one off a dedicated output. But the input impedance as far as we know is 20k ohms so 2 in parallel should be 10k. Any decent output should be able to drive 10k.
SPL 2control output impedance spec'd at 75 ohm. 21.3dBu Max out level. Should easily drive 2 LA90s in parallel.

Friends: I can't find this amp in the Electronics Review Index. It does not appear that I can see under Topping. Please let me know if you can see it there
