Ayre is good.Sold Krell and B&W a number of years ago including 805S.Most Krell could have metallic or "etched" mid but B&W is pretty forgiving and the 300i,S300 etc have that Krell grip on the bass that's great.150 watts is perfect power as well.Buy a used Krell.In any case 100 watts SS or near it or 60 wpc tube is needed (my friend uses a Cary Sli80 with great results with 805's and can switch from triode to pentode "on fly".If you don't need a sub out the Pathos Classic II or II hybrid at 70 wpc is enough power with tubes and SS if you like acoustic music and you volume roon needs aren't too great.
