Other (Power Conditioner, Racks etc.): Seakay Line Rover; PS Audio P300 for digital sources other than separate power supplies for DAC and SACD analog stage; Merrill Stable Table I; Justaracks, heavily modified by K-Works to isolate from vibrations
Tweaks: K-Works IsoBases under all tubed and mechanical equipment; Pon-Tunes isolation devices; Walker HDLs; Top Hat tube dampers; Suspendors; Vintage Telefunken EF-86, ECC802S and 803S small signal tubes and Gold Lion KT88 output tubes
Room Size (LxWxH): 20ft. x 18 ft. x 10ft.
Room Comments/Treatments: Not many treatments, as it's our living room--a few ASC tube traps, a few large plants; curtains and rug help damp what would otherwise be a fairly bright room. There are two chestnut fluted columns flanking my listening position which surprisingly act as sound diffusers and, given that my speakers are wide dispersion anyway, don't mess things up. The walls are plaster, and there are large open spaces in the rear and right side wall; the floor is 3-3/4 inches thick, over a 10 foot deep basement.
Music Preferences and Comments:
Music Used (Genre/Selections): Classical of all genres, with a preference for large-scale orchestral and choral works; 60's and 70's rock; folk and bluegrass; a little jazz.
System Goals/Comments: I look for something that can create a reasonable facsimile of the recorded event, and can then let me get lost in the music. I prefer to give up ultimate resolution to be able to enjoy recorded performances. I have a distinct preference for tubed equipment, if you hadn't already noticed.
System Strengths: Very musical and emotionally involving; strikes a reasonable balance between detail and musicality. Excellent bass extension and quality. The speaker system is particularly good at creating a holographic soundstage, very real sounding. The Jadis electronics are, to my ear, as natural-sounding as are out there, at least for everything other than non-acoustic music.
System Weaknesses: While it's my preference, the system leans slightly towards a darker tonal balance, and the highs are slightly rolled off compared to other equipment I've heard. I also really would prefer a dedicated listening room (as would my wife!). The speakers are wide dispersion and thus don't give the pinpoint imaging that some people (not me) prefer. The system on the whole is better suited to classical and acoustic instruments than rock.
Video/HT System: None
Other Interests/Hobbies/Occupation: Corporate finance attorney; I like and play all sports, particularly golf now that I\'m over 50. I sing in a number of choral groups, play guitar and attend many classical and other concerts.
