Adding Volume control to an older preamp

I need suggestions from the group please-

My current system consists of Harbeth SHL5 speakers, Pass Lab 150.8 amp, Audible Illusions Modulus 3 preamp, Denafrips Pontius II DAC, Wiim Pro streamer and Nordost/Monster cables. I listen to a mix of music but mostly jazz and classical I reallyI enjoy my current system.  

I would like some advice from members of the forum as to how to control the volume from my listening chair as the Audible Illusions preamp does not have a remote volume control.

As a quick fix, I recently purchased a remote for the Wiim Pro to control the volume at the streamer but have read that controlling the volume at that point in the chain is not the best.

I have come up with two possible solutions and would like your feedback is to which is the best or is there a better third choice? Also, WAF is not a problem as my listening room is in the basement .

1) I can purchase a Schiit Saga with a remote and use the passive mode. But, will there be any impedance issues placing the Saga between the preamp and the amp?

2) I can move the preamp next to my listening chair and control the volume manually but will need to purchase longer cables. I would need either 14 foot interconnects between the preamp and amp or 14 for speaker cables. From what I have read, shorter interconnects and longer speaker cables is the way to go.

Both solutions will cost about the same. Any advice would be greatly appreciated. 

Thank you in advance.
