Hello from NZ. My main listening is classical - Earliest is Buxtehude and latest is Pärt. Piano to Orchestral. My current speakers are Magico. They are nice and do classical just fine. I do not particularly recommend them but to get what you want I think the following need to be taken into account. First, you can improve your room. Judicious use of damping materials and experimentation of speaker placement can in effect largen your room. Second, there is no substitution for cubic inches. Yes small speaker manufacturers will claim otherwise - but it is difficult to work against the laws of physics. Third, do not get ported speakers (possibly a type known as Transmission Line). Once you lose the woolliness of the port you will benefit from a clear and more accurate sound. This is not without cost as sealed designs tend to require more amplification.
Finally I endorse upgrading the amplification. I think the amplification and speakers should really be regarded as a unit. In fact some manufacturers (eg ATC) do exactly that with the 'active' speakers.
