Classe cap series intergrateds.....

Do any of these units have pre-outs to connect a sub?
phasecorrect they all have at least 1 balanced input?
Yes both the CAP-101 and the CAP-151 have pre-outs and 1 balanced input. I run a CAP-101 100w per channel sounds great very smooth open. make sure you use good IC's and speaker interconnects.
