I ‘m using a Electrocompaniet AW-180 Mono-block and ARC Ref 6 per-amp with my Wilson Audio Sophia 3 speaker now. And I want to buy a new amp to replace my AW-180 this year. My target is either Pass Labs 260.8 Mono or X350.8 stereo, which one you think is better for my Sophia 3? Some of my friend encourage me to get 360.8, the reason is this amp has more power, and I don’t need to upgrade my amp in the future if I change my Sophia 3 to Sahsha 1/2 (My plan in next 1 or 2 years). But someone said 260.8 Mono is suitable for me because it has better analytical, more details and imaging, especially I only listen to Jazz music. And they said it should have enough power to drive Shasha. So which amp you think is a better choice for me in the long-run? My listening area is not big, about 220 square feet.
