I own a Hana SL and JC3 Jr. I only get a very low level "hiss" above 50% on the volume knob -- far louder than I’d ever listen.
Have you tried any other cables between the TT and preamp? Is the Sillnote Morpheus shielded and designed for low level phono signals?
Cable spacing may be the issue, but in the past, I’ve run phono cables (even cheap ones) quite close to power cables with very low to zero noise. More often, the noise is a cartridge -- turntable interaction issue, (like Grados on a Rega), a loose connection, or a faulty cable. I’ve now owned three pairs of defective Audioquest cables, so even "good" cables can be the culprit. I had one of their tonearm cables that caused hum simply because the spade lug was poorly crimped to the ground wire. You might also open up the JC3 and check for any loose connections.
You’ve tried bonding the turntable to the integrated but have you tried bonding the preamp to the integrated AND preamp to the turntable, using short bonding wires? That won’t likely solve your problem but it worked for me in a couple setups.
Double check the quality of connection between the cartridge and headshell. If you’re using an aftermarket headshell, that’s another potential problem area. I’ve had an aftermarket headshell with a neck that was just barely to short to allow good contact between the mating pins. Lastly, make sure there’s a good distance between preamp and any components with large transformers (that would include the 1200G).
