Hi Kun,
Glad to hear that you're enjoying things as is and not overly concerned about everything being technically correct - that is usually a sure sign that you've got a fine system at hand.
With my FS-888s, finished in burl oak, are in the family room 2 channel / HT setup. The 2 channel front end equipment is an Audia Flight CD2 and matching integrated amp. Dual Velodyne subs handle the very lowest octive and share time with the HT setup. The Audia Flight components have somewhat of an analog sound and have no problem handling the 888s. They are very well built and have an understated elegance about them that compliments the 888s. Though I might try seperates with them in the future, with HT equipment sharing the same space, there's no rush to make any changes for the time being. I've been lazy too and haven't posted this system yet - perhaps soon though.
The 688s, finished in burl walnut, share time in my home office with Micropure Kotaros (single driver w/ Murata supertweeter). As they have a very different sound character, swapping them out every few weeks makes things interesting. Front end equipment there is a Raysonic CD 128 and Triode Corp separates. Being entirely tube based, it's quite a different sound than the LR system and equally enjoyable.
Cheers,
Garry
