- Martin Logan Descent i

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.

I have listened to maggies several times and they always sound great. they require a lot of care with placement, though. In fact, about a year ago I visited a shop in Israel and listened to a sonus-faber fotura; they sounded worse than a pair of maggies (1.7 if I am not mistaken). A loyal client of the shop agreed with me. This was quite a surprise; a pair of cheap maggies outperforming a $20,000 speaker! I have also listened to a pair of Martin-Logan Electrostatic 'speakers at a local hi-fi exhibition held in Israel a few months ago; they sounded very transparent and did a nice "disappearing" act. And, Yes, the same shop also demonstrated the Pro-Ject 2 Experience, albeit with an Ortofon MM Blue cartridge, not the MC described above (Sumiko BluePoint 2). As befits a high-end system, I would have opted for a higher-caliber MC cartridge, e.g. a Lyra or a HANA or a Van-den-hull or a Stradivarius or an Ortofon A95 or an Ortofon ANNA or an Ortofon SPU. But I am nitpicking; I am sure the Sumiko sounded just fine.
