are phono cables different from regular rca's?


to go from a step-up amp (Hagerman, FET) into the the mm input of the phono preamp, it would seem that an rca-terminated "phono" cable would be indicated; it's outputting a signal essentially the same as a mm signal from a cartridge. Is a "phono" cable intended for such low-level signals preferable to a normal rca interconnect, in this application? Are they constructed differently?

Well, you can indeed use any interconnect if you don't mind the hum. Best that it be shielded.
Most interconnects are shielded. I've never had a problem
with hum because of the interconnects I've used. I would not use an unshielded cable (such as PBJ) for this application.
It's all relative to the system and surrounding environment. I use all unshielded IC's (my brand) and have zero noise/hum....dead quite in my system.
