Solid State Phono Preamp Suggestions $3k-$4k

I reached out to Pass Labs and the output impedance of the XP-17 is 110 SE and 220 Balanced.  I was planning/hopping to run balanced into my BP-26 preamp so I'm a little concerned the 220 won't be a good match for the imput Impedance for the Bryston at 10k ohms.   

Same with the Sutherland Duo at 200 Ohms.

Looks like the Parasound JC3+ might be a good option with an output impedance of less than 100 ohms.  

How hard and fast is the 1:100 ratio that seems to be the recommendation?  

I believe it is 1:10 ratio

220 ohms (balanced) into 10K ohms should be absolutely no problem.  Why do you think it might be?  Who recommended 1:100 ratio?  Typical recommendation is 1:10, minimum.  Also, are you taking into account the input impedance of the Bryston in balanced mode? Because it might be 20K ohms, not 10K. Bryston are not very forthcoming about stating the input impedance of their high level inputs, but after downloading the owners manual, I did see that the TAPE IN input, which is single-ended, has an impedance of 10K ohms.  This suggests that the balanced inputs would be in fact 20K ohms.

Be aware that the JC3+ has a fixed MC gain of 64 dB.

Thank you  @allhatbach54 and @lewm ,  I may be misinformed. I was aware of the recommendation of 1:10 when it comes to your amp and preamps but read somewhere that 1:100 was the recommendation when dealing with matching up your phono preamp with your preamp.  

I reached out to Herron as I was very interested in the VTPH-2A given the rave reviews on this site and others but he did not recommend pairing the VTPH-2A (400-500 ohm output impedance) or any tube based preamp for that matter with the Bryston preamp.  

@ericsch Thank you for the heads up.  In the reviews I've read on the JC3 they did mention the fixed MC gain. If I do go down that road it will be with eyes wide open on the cartridge limitations.
