"Best" is kind of a subjective thing that only you can answer for yourself. I, for example, prefer that the midranges be "just so right" with lots of "air". Others prefer bass with lots of "slam", while still others like fine detail. I don't like etched highs, or loose bass. For me, the Atma-Sphere M60's do the trick, I would venture to guess that the 30 would be just fine as well. However, all those tubes do heat up the house, and, in the summer, I use a Forte model 4a instead. What I am trying to say, is that in order to make suggestions, your music preferences, room acoustics, and what it is that your trying to achieve, as well as cost considerations (there HAVE to be a few cost considerations), need to be known. If you don't like all the maintainance that comes with tubes, consider a nice solid state performer (the YBA Integre DT comes to mind, and, at a reasonable price used), but price will still eventually dictate what can be recommended. Choosing the gear is a large part of the fun, use others advise for a guide, but, make the choice yours. Happy Listening, and good luck in your quest!
