The XONO has replaced the GSP combo, and while the comparison has been made slightly closer (i.e., improved bass frequencies), differentiation between systems is still possible. We found that the mid-high frequencies were more clearly represented (increased volume perhaps) with the expensive setup as compared to the less expensive setup. Our next step is to record the less expensive turntable and cartridge through the Steelhead to determine the overall effect of the turntable and cartridge.
