i have been considering getting the 125 wpc emotiva upa-2 amp to give some oomph to my system.i have an 80 wpc nad integrated amp that is hooked up to a pair of ruark epilogue bookshelf speakers which are measured at 86db.would bi amping the ruarks significantly improve the sound quality via the emotiva?what i am looking for with bi amping is using the additional power to get better bass definition,more "bloom",so to speak coming from the speakers,etc.
