Marbles- I'm using Polk LSi9's for speakers (88 db sensitivity I believe), an Ah! Tjoeb cd player as transport, and a Musical Fidelity A324 DAC. Used Quad 63 USA Monitors for many years, with a privately made hybrid preamp; but missed the low bass, loudness, and dynamics. I'm hoping to regain much of the midrange purity I had with the Quads; if not, maybe I'll try Martin Logans.
I like the NuForce because resale value is likely to be high, and because they should be able to drive most speakers.
