tgm,sorry for rambling on about impedences - I totally missed your mention of the LOGOS not having INPOL circuitry, which until now I thought it had - hence my useless response.
I believe that the LOGOS would really be worth a try on your Cremonas.In my medium sized room on the B&W's (which are only two way)the LOGOS was great. As Chams says not a solid state sound, bass and dynamics were very good but I felt that the TT was more liquid with a better (marginally)soundstage.Where I thought the TT was significanty better was the area of air and resolution particularly on voices.
