The Logic Off Topic list

Hi OT-luggers, i'd like your advice on the following.

It occures to me that material I produce seems to lack 'power' 
and 'presence' in comparison with other 'top notch' productions.

I'll give you a short description of the way I usually work:
- i record all midi tracks from outboard gear to audio tracks,
- i add the plug in effects on individual and bus tracks,
- i add reverb (from ext processor) to the bus mix on mixing desk 
(328)

this mix i 'loop'  back to a stereo track in logic.

On this stereo track I do some final editing, including:
- eq-ing
- stereo spreading
- limiting (waves L1)

I tried to raise the L1 treshold level to a setting of +11, to 
compensate for power and presence. But it seems to have a negative 
impact on systems with a low amplifying power (eg. car stereo, pc 
multimedia sets): the music will sound rather distorted, when turning 
up the volume. 

Can anybody give me hints, how to achieve the results I'm after?

Many thanks in advance,

EK
