"Hey Rich, I was thinking about what I was missing, and its the intial attack of the front, upwards curve of the sound. I can hear the guitar being played, but I want to feel the pluck on the string before the note sounds. The twang and percussive effect of the double bass player digging into a string."
Hi Jaffa,
Absolutely, that's a good goal, and just to summarize; your goal was to feel and enjoy the Music better, at normal listening levels without turning up the volume excessively high. You said your room was 5 meters x 6 meters which is equal to 16.5 Ft. x 19.8 Ft., which is a pretty decent sized listening room. I know that you would also like to; feel the attack and pluck of the Guitar, the thwack of the Drums, and the twang of the Double Bass, as you so eloquently stated above.
Well, just to put some of this into perspective for you, because there is certainly a lot of good information here, that can be very overwhelming for a new comer. You could certainly buy cables, and power cords, and room treatments and it all helps tremendously, and I mean that sincerely..., it really does and I have all of it as well. Even buying larger amps will primarily allow you to make it louder, and yes there is also the usual tighter bass, and other audiophile benefits, etc, etc..
If I buy a new suit, I may feel and look better, but I'm not suddenly going to become 6.5 Ft. tall
So..., to get the sound that you want, in that size room, you have to move a lot of air and excite the air in the room.
I understand that you are using very good, but "Small Studio Monitor Speakers."
As far as I know, there's are only a few ways to accomplish your goals:
1) Turn the volume all the way up, as you're doing, to raise the SPL in the room until it's uncomfortable.
2) Add one Subwoofer and introduce more problems and then we could start another thread on that one.
3) Buy two subwoofers and pray.
4) Add a center channel speaker, surround speakers, a processor, equalizer, more power cords, clutter up the room more and call it a Home Theater.
5) Move your Monitors into a smaller room in the house and enjoy them there.
6) Buy Larger Floor-Standing Speakers that moves more air at a lower volume, so that you may appreciate; a more involving transient attack of the leading instruments, without destroying that silky smooth sound that you so enjoy.
Oh, one more thing...., if you buy larger speakers, then you may need larger amps, and better cables, and fatter power cords, and more accessories, and max out your credit and take out a loan, and then, and only then, are you an Audiophile...
Now, my friend..., you really do have a lot of difficult decisions to make ; )
Enjoy and Happy Listening,
Rich
