Budget system, but where's my punch gone?
First post, although I have frequented here many times and learnt a lot while loitering. So thanks for past and hopefully present help.
As you can see from my sig, I'm running a budget system and it's done me proud for quite some time. However we've recently moved home and the lounge is now somewhat larger (7m x 4m). I'm assuming as a result I've been somewhat less satisfied with the sound my system is producing.
The Epos M12's are beautiful sounding speakers and with my current setup (bi-wired from both (A+B) speaker outputs from the Rotel) the pace, image, highs and mids are amazing and the vocals... OH THE VOCALS! So good they make your hair stand on end. I literally get goose bumps. It might just be my ears, but both male and female vocals from those whee speakers are just outstanding. However, the astute might notice the absence of bass from the list of positive traits and may rightly or wrongly think here's yet another "needs bigger/active (staying unbiased here) speakers" post, but it's not that straight forward.
I've read a fair number of posts asking what floor standers or sub they should purchase when in my situation, but I'm unsure and hesitant that this is the only direction I have to head in. My speakers and seating are arranged across the short length of the room. I sit 2.8m away from the speakers which in turn are 1.8m apart. I can easily get the Epos to produce powerful room filling bass down to more than acceptable frequencies. It's nice and tight on drums and has lovely decay on bass strings all pleasantly neutral to the ear. However, and I struggle to describe the problem here, some of the low frequency range seems to have lost it's impact. The tracks sound well paced and lively but say when a bass drum kicks in... well nothing. It can sound immediate, precise, tight, but have no impact or excitement. In the next moment a bass guitar, synth or even the same bass drum might hit a note that sounds fantastic. It's certainly a new problem that I didn't notice in my previous arrangement even though the positioning was very similar.
The reason I don't jump with both feet onto the bigger speaker boat is that the Epos offer and have delivered so much that I would hope to look to other parts of my budget system (whilst still on a budget) for improvement first. Can this issue be addressed with a new amp (creek Evo 2 at a push)? Maybe a power amp (second hand RB-06?) from the pre-amp out on the Rotel? Or maybe a more suitable cable to the bass drivers or new CD source?
I should mention I have tried listening to the Epos epic 5's and Q Acoustics 2050i on a Rotel RA-10 (also 40W) and yes they sound nice, but to my ears the mid and vocals just don't come close. My music tastes can be pretty much extrapolated from the test CD's I took to the auditions. Pink Floyd, Dire Straits, Radiohead, I Am Kloot.
What would be the most likely course of action to re-find the punch that's gone missing without loosing the traits I love from my setup and paying a fortune?
Thanks for any help received.
