The Logic Off Topic list

This its a important question for my business.
Below are my home working tools:
Mackie D8B digital mixing desk,digital outs and ins for computer 
comunication.
Mac G4 466 with somes HD (one just for audio purpouses)
Software: Potools LE with digi 001 interface an Pci card.
Logic audio platinum 7.4.3
Plugins : TC Bundle,Waves gold bundle,antares autotune and 
mic modeler etc,etc... ( I think the best for the present) Plus the 
plugins from the Mackie D8b (revs,delays..) 
System monitoring: two Genelec 1030A.
Enviroment Without acoustic treatment.(I will do it soon.)
Here it came my question.
If i make all the recording for my musical produccions in a 
professional studio in the town.Can i bring all that tracks to 
home and continue mixing them for to obtain a final 
professsional work just for to deliver it to the record company?
As many of us I am producer,song writer,musician,etc,and,till 
now, i have done all my mixes in comercial studios having at 
home a professional stuff that normally we only use it for 
monitorization my sound modules.
Its dificult to me to obtain good mixes in comercial studios.There 
is a lot of reasons.
The main ,its dificult to me to work with diferent stuff on every big 
studios that I use to go because each mixer desk or outboard 
gear are diferent from a place to another.And the engineers not 
ever are the people who are the best work mate for me.I like the 
sound but not the final mix result.Because i did it in a 
unconfortable enviroment.
Whe i bought all my gear three years ago,i never thought that the 
digital tecnology it could oferr to me the facility of doing good 
professional releases at home.Because all the time i was 
thinking that i was buying 
broadcast or projet focused gear, good for demos and litle works 
but not for serious releases.
Till now i have done all the mix work as one more 
engineer/producer.But i never thought that my home gear could 
obtain
top quality .
May i take this decision without the fear of being wrong or may i 
need to buy more class A tuff?(Already i know I must make some 
acustic treatment in my working room before, but I am just 
talking about all my stuff)
I wish to know if there is any one making final professional 
works with a stuff like the mine.
The kind of music that I do its wide (from folk to dance 
music,beides Pop)
I need some help of you to take a good decision.
Thanks
Sory for my english Im from Madrid
