Don't forget your source impedance. Also your filter seems to he losing 6dB, which is a little less than ideal. Usually a butterworth will have 3dB loss at frequency of interest and a chebychev has less loss at FOI but has a designed amount of ripple across the low pass range. (3dB is a power half, 6dB power quarter and each 10dB would be loss by a magnitude of 10)
