Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre

I mean, I'm running this through this Sys passive pre, and the there is plenty of volume.  I'm just wondering if I'm going to damage something...

You're a Godsend.  Thank you so much!!

George - 

If I'm putting 2k ohm into a passive pre with an input impedance rated at 10k ohm, it means I'm not going to get 100% of the bandwidth? Signal?  

The output impedance of the source is 2kohm, so the load it should be at least a 20kohm passive. The the output of the passive will be fine with the 100kohm input of the poweramp.

George -

Ah ok - that makes sense.  Noob that I am, it did not occur to me that passive pre's have in and out impedance.  

Seems I'll either have to change pre-amps or the phono pre.  Maybe.  I have a Schiit Valhalla 2 that I can try too, but there's no spec on input impedance.  

George - 

Thanks so much for your response!

It seems this phono pre is a little weird in having 2k ohms out.  Manual does say it can "drive loads down to 600 ohms".  And it has gain knobs I can play around with.  

I'll keep playing with it.

This is a low-impedance output (nominally 2 kilohms) that can easily drive any standard vacuum-tube or solid-state amplifier.

"

But yeah - I see a bunch of phono pre-amps that are less than 100 ohms out, so 2 kilohms does seem like a big difference.  

Anyways, I really appreciate the help, all!

Output impedance:
2 kilohms nominal; will drive loads down to 600 ohms with slight loss of output level.

Yeah, it's pretty 'hot'.  Gain is only at 9 pm and I have plenty of volume.
