    • Krell DUO 300 XD
    • Nordost Blue Heaven
    • Mye Sound Mye Stand
    I still kick myself for not buying these sooner. They effectively turn Magnepans into different speakers with significantly greater punch in the bass and mid-bass ranges. Highly recommended.
    • DBX Driverack VENU 360
    Speaker management unit which serves as a preamp and DAC. I have this one set up to handle the following duties:
    -room correction
    -active crossover
    -gain matching
    -delay (midrange/tweeter only, .27ms)
    -phase (subwoofer only, matched to bass panel using a sine wave test tone at 80 Hz)
    -limiter (applied for tweeter protection)
    • PS Audio Stellar Phono Preamp
    MC Gain: 72 dB
    Cartridge loading: 100 ohms
    • Anthem MCA-225
    Gen 2
    • Furman Elite 15 PFi
    • Aurender N10
    • Mogami Platinum Studio XLR
    L & R analog from phono preamp
    AES/EBU digital from Aurender N10
    • Auralex Acoustics Inc. LENRD Bass Traps
    Please pay close attention to Auralex's advertised absorption coefficients before buying these. Calling them "bass traps" is a bit of a stretch. Maybe mid-bass. Their absorption capability effectively begins at around 150 Hz and continues into the 4k Hz range. I've found them to be virtually useless for absorbing pesky bass frequencies. Instead, I use them to absorb and diffuse midrange and high frequencies to great effect.
    • Rega Planar 10
    Equipped with the Rega Apheta 3 cartridge.

It appears you're still using the factory stands.  I'd highly recommend the Mye speaker stands, which made a huge improvement with my 3.6Rs.  The ability to adjust the stands will eliminate the need for the shims.
