Nope - the biggest factors in descending order of effect are (1) speakers, (2) room acoustics, (3) amplifier. If you want more lively sound without spending significant money, adjust the acoustics. Sharp hard edges that reflect sound should make your system livelier. This is pretty much the opposite of what people generally do to adjust room acoustics; the more typical problem is that the room is too reflective. Try that and see what happens. Dali's are nice speakers; kind of soft, but nice speakers so I wouldn't do anything wtih them - you may want to take a look at the amp next. Another very recent thread expressed the same type problem but with a reference to source material (CD's) look at my response to that OP for my take on the Rotel sound and my suggested alternatives.
changing overall tone
have a mid-fi system and would like to know what to do next to make sound more alive and not so nuetral to dull sounding. I play vinyl on a original rega 2 and use audioquest type 4 speaker cable with a jaguar audioquest IC into a phono amp. Have dali ikon 2 speakers and rotel ra 1062. Should I be looking at different IC or speaker cable? Thanks.
