advice needed on 1st real stereo system

My first good stereo was a KLH Model 20...I only mention this because it makes me happy to think about it. Note that a tubed integrated can be had relatively cheaply and they're fun to look at (Jolida, Primaluna), and great sounding cables can be found used for a huge discount over new stuff and are often in great shape. I bet that new hybrid Rogue integrated amp (tubes and a class D) sounds great and it seems inexpensive.

Again, buy used (or better, "recently discontinued")...plenty of upgraders are dyin' to unload their stuff on you, and this approach really works. Most of my gear, be it pro audio, guitar playing items, or hifi things in great condition have been relatively easy to find if you look around some. A couple of examples: A friend had a pair of Silverline Preludes bought new for $1200 or so, combined with a new small REL sub costing maybe $500. I thought that combo sounded sweet (and my speakers had "issues") so within a couple of weeks found the Silverlines for $400, and an older REL for $200. Just bought a new but discontinued Taylor guitar for $1000 less than the model that's now replacing it. Do this, and you will be happy.
