FWIW and slightly OT:
When my Genos arrived about 5 weeks ago, I set it up temporarily in my living room with a pair of six-foot Magneplanar MG-IIIa panels and an M&K Volkswoofer, biamped from four Sunfire 500W amps fed through a Marchand active crossover. Talk about impractical! But it blew my socks off, and everybody who came to hear my new keyboard was astonished at the sound quality. I'm still looking for my left sock.
Now in my music room, the Genos is playing through a MOTU UltraLite mk3 into an Alesis RS150 power amp, and the speakers are a pair of Dick Sequerra Metronome-7's and a huge DBX SW-15 passive sub. With some minor EQ tweaks the sound is still magnificent.
If I ever take it on the road, it will go through a pair of Yamaha Stagepass 1K line arrays (poles), which have a very smooth sound and surprisingly good subs. Again, some EQ will certainly be required, but gigs require EQ tweaks for each different venue.
I also have one EQ preset that I use when playing through my Sennheiser HD 650 headphones (which are open-back and comfortable enough to wear all day), and another EQ for the closed-back Sony MDR-7506 phones, which are a standard for mastering.
What I'm finding is that the very flexible master EQ controls are more than adequate for pretty much any speaker setup one might encounter. Of course, one reason for the sound quality is that (as I understand it) all the samples are losslessly compressed or uncompressed at 44kHz x 16-bits (which isn't the ultimate, but it's good enough for 10,000,000 CDs!).
