AR LS 26 and Pass Labs X350.5 Compatible?

I forgot to mention that I have an X250.5 (same input circuits/same drive impedance give or take as the X350.5).

For the record, let me state that these single data points are pretty useless. They are mostly marketing figures. Think about it folks. Impedance is a frequency dependent resistance to current. On the one had too much data can lead to analysis paralysis, but otoh, too little can lead to bad outcomes. I really appreciate the measurements that stereophile presents when they do equipment reviews. They pretty much cover the spectrum. Of course the final proof is in the listening, and no one can predict that.
Audiofeil, unless these folks have the data in question they are also taking a guess (albeit an educated one at that). Don't get me wrong I love pass products and the company is excellent, but it is what it is.

Thanks to all who replied to my thread. I will try to investigate more thouroughly and see what Audio Research has to say on the matter but according to Dev, Joey54, and Audiofeil, it does look promising.

I have the ARC LS-25 Mk I and Pass X350.5. I remember reading somewhere before about the impedance matching issue between these two components, but I could not find the threads again.

I just did some research and this one talked about the impedance matching:

Per the manuals ARC LS-25 Mk I has output impedance of 650 omh (balanced), and the Pass X350.5 input impedance is 20k ohm (balanced). Per the above thread, the ratio should be at least 20x. The imput impedance of the X350.5 is at least 30x of ARC LS-25's output impedance (20k ohm/650 ohm = 33.8), so it should be OK.

tried ref 3 & 350.5. Very good combo, no problems.
