    Default System #420 (CLX, Descent-i, Stage X, Summit)

    Name: Jim Showalter
    Location: Los Gatos, California
    ML Models: Martin Logan CLX Anniversary, pair of Descent-i, Theater-i, Summit (for rear speakers)
    Year Purchased: Many years, oldest piece of equipment is from ~2001
    Mods/Changes: None

    Associated Electronics:
    Oppo BDP-105
    Lumagen Radiance XS Scaler/HDMI Extender
    Pioneer Elite PRO-141FD
    Sony TA-P9000ES
    Anthem Statement P5
    Furman IT-20 II
    Ebtech LLS-2-XLR
    Xantech IR Repeater

    System description:

    All decoding done on the player. Pure-analog stereo/multichannel signals through the system.

    Works very well both as a two-channel system and as a home theater.

    We're fortunate in that our living room allows setting up speakers in correct ITU 5.1 (3/2) orientation and spacing, and no room correction is needed, despite the woodstove and pool table in the rear. (We move the speaker near the woodstove out of the way on those rare occasions when we need to light a fire.)

    I've been an audiophile since 1971, when I wandered into Gaylord Audio in Concord, California while I was supposed to be in school.

    I'm fortunate that my WAF is a perfect 100% (we're both engineers), so we've built this out together, and she likes the way the system looks as much as I do.

    Equipment closet is off to the right and ~50' from speakers and monitor, which produces a very clean look and hides distracting front-panel lights to improve watching movies, but also introduces possibility of ground loops, EMI problems, and HDMI dropouts. These are addressed by running cables in individual grounded conduits; running LFE balanced instead of single-ended; using 6' HDMI cables with proper EQ and matched Lumagen scaler and HDMI extender; running dedicated 120V power in separate, dedicated circuits to the left and right rear speakers, center speaker, left front speaker and sub, right front speaker and sub, and flat panel; and conditioning the power for the preamp, player, and scaler.

    Cabling is pragmatic (high quality, reasonably priced, no voodoo): Blue Jeans Cables for signals and HDMI, Martin Logan CLX power cords for speakers, Take Five Audio/Neotech power cords for Anthem, built-in power cord for Furman, commercial-grade outlets.

    Equipment rack is Metro Super Erecta shelving, which is inexpensive, attractive, flexible, strong, mobile, and cool-running.

    Media racks are from Boltz. Strong, attractive, and flexible.

    Some photos. More are in subsequent posts (forum has five-photo-per-post limit).

    Very nice system. Have you tried a little toe in on the speakers?

    Nice to see another Sony TA-P9000ES passive preamp Jim.

    Incredible value for the money and hard to find. This was the product of a once off project inside Sony from their HIFI Division to make a home theatre for hifi affictionardos, I don't think they ever did another HT project, since then it has been one box solutions from their Home Entertainment Division.

    Great set up.

    Ron: They are toed in, per the instructions where you sit in the center with a flashlight, etc. It doesn't come across well in the photos.

    Big Jon: The center does very well on the floor. It's angled up a bit and smacks the viewer right between the eyes!

    Krazikiwi: The Sony is an active preamp, just a very clean one (and with discrete logic no less). We have three of them, for fear that one might break and there'd be nothing comparable to replace it with.

    (Photos of Oppo are obsolete. It is now a BDP-105 instead of a BDP-95. No more fan!)

    And some more. Conduit run in walls, under house, and up into equipment room. Work done by Terry Welfring Construction, San Jose, California, and his dynamite crew, the Hernandez brothers.

    And a few more.

    Quake bracing and UV protection.

    The fabric is UV-proof Solarweave, from rockywoods.com, cut and hemmed by Leading Edge Sails, San Mateo, California.

    And (not shown) the plasma is protected by a circuit described on my free-inventions blog (http://free-inventions.blogspot.com/...touts-for.html).

    Your room could do with some treatment after investing that heavily into the gear. Nice gear you have at that

    The open back wall and second story, and high ceiling, seem to eliminate standing waves. The carpet knocks some resonance out. Which is fortunate, because we don't like the way most room treatments look.

    Nice system Jim, I see that you are using a Oppo 95 too , are you using his analoge outputs also for 5.1 surround ?
    Such a beautiful music system deserve also a projector ?

    Yes, Oppo's analog to Sony preamp analog.

    Not a big fan of projectors--they always seem too dim.
