Thoughts from the customer?
" I finally received my Musical Fidelity M6i integrated amp last Thursday and finally got it hooked up on New Year’s Day (yesterday). It is an awesome combination with the Polks and will only get better as both the crossovers and the amp get some “break in time” over the next month or two. Using my old Carver I could tell the difference with the new crossovers, but with the new Musical Fidelity amp, the Polks have never sounded better Trey. I am extremely satisfied with the crossover upgrade as both soundstage depth and width have improved significantly from the original crossovers. Thanks again sir for all t he help and patience. It is a great feeling to have a stereo that rivals systems costing 2 or 3 times as much!" - Michael (polk Audio SDA1A Castle Level Modification)
