As title says I need some advice. This is my first power amp, which is a Audio Alchemy OM150. From my research it was good amp for its time. I'm looking for a pre-amp to pair with this amp. I don't know to much about this amp as it was a spur of the moment thing and got a good deal from a co-worker who upgraded to a Bryston amp I believe a 4b3 . Unfortunately I'm having a hard time fine all the spec or op manual for this amp, any info would be awesome. As of right now I'm looking at the Schiit audio Saga either the S or the + ( steer me to the right one) but I'm not set on it, if you got any recommendation its welcome, id like to keep the price under $500 CAN if possible. What I like about the saga is the volume control, remote control, and the two out-puts. I read through Amirm review and while it was a positive, i was little concern when he mention about "input impedance should be at least 30k Ohm". from what i found online the OM150 has 40k ohms so i should be ok. Can anyone confirm the input impedance spec thanks. My current set-up is a 2.1 system with the source coming from a computer, the amp is OM150, bookshelf speaker are Sony sscs5, Nobsound G2 amp to power my passive sub. Sorry for the essay im jus excited. So far with what speakers i have love the sound this amp makes.
Any help would be appreciated.

A 40K input impedance and 29dB of voltage gain is easy to drive, so just about any competent preamp, tube or solid state, will work with it.
