Well I come home last night around 9:45 and right when I open the door I see the package I've been waiting on for 6 weeks. its my SWR IOD preamp.. I only got to play with it for a few minutes at a very very low volume but right off the sound is 10 times fatter than before.. I was wondering for you owners of IOD preamps. Do you leave a space in your rack between the IOD and all your other gear or do you leave no space at all? i know the IOD gets pretty hot and I only have 1 space left.. and thats going to be for my korg tuner that should be here today.. what do you think?
