Yes the Shrimp is entirely a single-ended design. The circuitry uses single-ended topology. In order to be able to provide balanced inputs or outputs we would have to convert the signal to balanced using something like some IC's or transformers. Both these options would add more "stuff" to the signal and be certainly audible detracting from the pure sound the Shrimp provides.
If you are dealing with balanced source outputs or driving a balanced amplifier with the Shrimp, check to see if you also have unbalanced connections on that gear, change your cables and go with that. You might be pleasantly surprised that they too added extra audible "stuff" in order to provide balanced XLRs and the RCAs that don't have that extra "stuff" in the signal path actually sound better. (Depends on a given unit's specific design.)
Or use some RCA to XLR adaptors. Most balanced gear has no problem being driven single ended but check with the manufacturer if they are going to want the negative pin 3 of the XLR grounded or floating. Transformer-coupled XLR jacks always can be driven single-ended by running HOT into Pin 2 and grounding pin 3 to pin 1. Some IC coupled XLR inputs will want pin 3 floating, others will require it to be grounded when running single-ended into it. Check with the manufacturer of your gear to see how to hook it up single-ended.

Badge Lamp: LED illumination
RF Remote Control: commands volume control UP/DOWN; uses 9V battery
Power Consumption: 55 Watts (485mA 120VAC)
Operating Mains Voltage: Units are purpose built for original destination country's mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage. 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.
