Personally i think the 751 probably did not partner well with the amps you listened to, also listening to the speakers at home will sound different to the shop. I remember listening to my Mission 753s in the shop and was not impressed, the dealer let me take them home and the 753s are still with me 23 years later. If you are looking for a simple integrated amplifier i would suggest a old Cyrus 3 not a 3i as they have different style of sound
