Cable Length from Sources Integrated AMP


I have recently purchased a VIVA Solista integrated amp and want to locate it between my speakers. My rack is on the side wall and I would need to run single ended interconnects from my phono preamp (EAR 88PB) and DAC (Audionote), run would be approximately 18 feet. Both sources have a very low output impedance. I see many systems use short connects to the preamp and a long run from the premap to the poweramp. Since there is no preamp in my system, can I do the same with source components running to an integrated amp? Is there anything in the design of a preamp that allows it to drive longer cables versus a source component such as phono preamp? Any and all advice would be appreciated.

Thanks for your response. Yes, all line level, the distance between the turntable and phono preamp is short. So, if I understand correctly a component such as DAC or phono preamp can drive longer cables equally as well as a preamp because they are all line level?
