    Need some thoughts on this; Can we A/B 2 preamps into the VTA ST120? Probably using " Y " cords on the interconnects or would this load down the input of the amp? I have 2 PAT5 , one original / one with a total rebuild of all boards/parts from Akitika, using op amps NE 5532 and OPA 1161 on the phono boards. Also have 2 identical Thorens tables. Would love to hear these side/side to my K-Horns. Thx, Dale
