impedance matching and interconnect capacitance

I am considering moving my rack from between my speakers. The move would require me to have 25ft long interconnects single ended between my pre and my mono block power amps.

According to the specs of my amps, the impedance matching should not be an issue 260ohm output from my ARC SP-16, into a 100K ohm load at the input of the Quicksilver Mono blocks.

The manual for the SP-16 states that a maximum output capacitance is 1000pf.

I plan on using Mogami 2549 as the interconnect with a total capacitance of 87pf/m or 661pf total for 25 ft [7.6m] (not including connectors). This would leave me 340pf shy of the limit. Is this enough or are there other sources of capacitance to consider?

Great cable in one of listening rooms we have a 5.2 system done completely in Mogami XLRs and speaker wire.
We just changed the XLR runs but they were 20 ft with a pair of Meitner MTR 101s. The rear channels are with Mogami and are 35 ft runs that sound better than the Straight Wire 10 ft runs.
