great bookshelf speakers vs 12-18 k floor speakers


Just something i never considered, if you have a rather small room 13x20 with less tha perfect accoustics (Glass walls),high-rise. Anyway, i have always had tower speakers, currently Paradigm S8's v1. I have never explored smaller speakers, the so called bookshelf. Can i buy smaller speakers and still get the full range and soundstage that i get from the floor speakers? What would you consider as the best... especially when you don't have a large room. I don't always compare by price although you'd think a 15,000 set of speakers should be all around better a than a 5,000 set of bookshelfs? I have 180 Rouge Audio monoblocks, Rouge 90 pre amp, Ayon c-2 CD, Shenada Hydra 8 and much better than mid range cables.

I hope to have my Nano monitors by the end of the month. They'll be replacing a good two way floor stander as well. Looking forward to hearing them

Dynaudio C-1, Sonus faber Cremona Auditor Ms OR Guarneri Momento. These are some of the better monitors around. Perfect for a room your size.

Possibly even better still the Raidho Acoustics C-1.0 which I own.
