Thanks for your input everyone. I realize that I did not specify anything about SS or tubes. At this point, I'm thinking SS. Seeing as I'm just getting into this, I'm leaning towards simpler, easier, lower maintenance alternatives and SS seems lower maintenance than tubes.
Also, I listen to all kinds of full range music - not just "reference" recordings. I get the sense that SS will have a firmer grip on the low end, which I imagine will be better for rock, house, hip-hop, etc.
I like the idea of an integrated due to "ease of use" but I wouldn't say I'm settled on that if I can get separates that sound better at a similar price.
I realize this isn't going to be the be-all-end-all system but if I could spend a few grand at this stage and get a high quality, competent system to start and develop a better understanding of my tastes and preferences as time goes on - then that's a win.
Thanks again for your help.
Cheers,
Alex
