My girlfriend is pissed

What type of rack to you keep your gear in? If it's something fairly sturdy (like Zoethecus) and if there is nothing sitting on the top shelf, bend her over the rack and go for it.

Her weight will improve the rack's mechanical isolation properties...

Be nice to her.
Have some serious rolling with her before you do any tube rolling............

My main system is in my bedroom because it is the only room with the right dimensions. this allows the ability to do both. However, as much as I enjoy music, if it had to be one or the other... I guess this makes me not all that dedicated!

Girlfriend?! Do you think that I can really afford to keep one AND maintain my audio addiction?

Play some smooth jazz or romantic ambient instead of rock-n-roll, place some candles and champain and combine hobby with responsibilities.
