I started from ground zero with a set budget and found myself starting with speakers and then amp and preamp. I must say I knew that my dedicated listening room was going to be same for the next 5 years so was comfortable with zeroing in on my speakers. I started with Magnepan 1.7i speakers, ARC REF 5SE preamp, ARC DS450 mono-block amps and lastly my source a Meridian Media Core 200 media streamer. I knew that I was going to follow my retailers yearly upgrade options on speakers and that I would eventually land a pair of Maggie 20.7's. Now based on the perception that Maggies require so much power my amp choice was truly wrong and eventually I replaced the solid state monos with some PrimaLuna Dialogue Premium HP mono-block tubes and I must say I am musically satisfied. Next purchase will be a turntable as I look to scratch my vinyl itch. Not saying by any means that I did it right but room, listening levels, music preference and speakers were the starting points for me.
Cheers
