Just getting into mid-fi need advice

After looking up all the messages out there, I am a little scared to ask this question with the title "hi-fi" as I am afraid my budget might not buy me entry into one so have titled it as "mid-fi"
I have come to the following conclusions,
I need a setup for a sterio system only (no 5.1/7.1 stuff).
I need advice for speakers I was thinking of the paradigm reference studio 100 V3 speakers.
I listen to classical, rock (not heavy), indian music, acoustic guitar etc.
I am willing to spend another 1000 on the components and was thinking of buying them second hand here at the gon.

Please help with recommendations.
Also I am a little confused about the buzz on tubes, actually I was quite surprised to see so much enthusiasm about them. I am a electronics engineer and work in semiconductor devices, its been ages since I read about tubes however I was impressed about all the class a amplifiers out there using tubes and the talk on solids clipping harshly. Do you folks think that using a solid state amp in the linar regime will still not produce the sonic quality of a tube?

Please advice, if you think my rather no-knowledge questions sound stupid please accept my apologies.
