Keeping it as simple as I can keep it without compromising what I want. I can sum up my thoughts with a sentence I once read:
"I am of the opinion that the better a system is, the longer it takes to understand its strengths and weaknesses"
Primary goal: To hear the lungs, fingers etc behind the "noise". Makes it very engaging.
Secondary goal: Being honest to the recordings. I say honest even though I was not there when things were recorded ...so I can only speculate :)
I will never replicate live music. Whew ..got that out of the way. So, instead I choose to see how engaging I can make a room sound ...engaging enough to forget about some things, shake up some other things and to share a bit of the emotions someone many decades ago went through.
The room is half the system! This is a very very challenging room 17 feet X 11 feet x 14 feet peaked ceiling and a suspended floor. The ceiling comes down to the floor on one side and to 5ft 9 inches on the other side - so the 17 feet is not really 17 feet. Speakers were moved around the long wall and short wall before anything was added to the room to find the most favorable spot. The results forced a near field listening environment using the long wall placement with the speaker center deliberately not lining up with the peaked ceiling line (preventing standing waves). This left the back wall just 1 feet from the listeners ears.
[lessthansign]b[greaterthansign] Acoustic treatments - I like a lively room, and I am not a big fan of absorption ...so I have used it sparingly. I started adding one treatment at a time and voicing it to see if it stayed or not ... a lot did not stay! [lessthansign]/b[greaterthansign]
[lessthansign]b[greaterthansign] Front wall[lessthansign]/b[greaterthansign] - Plants around the dipole speakers to cause natural diffusion. GIK 13 root Diffusors between the speakers. [lessthansign]b[greaterthansign] Side walls[lessthansign]/b[greaterthansign] - Left wall is naked currently, right wall has CORE AUDIO DESIGNS Diffusors covering both the first and second reflection points. [lessthansign]b[greaterthansign] Back wall (corners included)[lessthansign]/b[greaterthansign] - Has GIK Tri traps and 244 bass trap [lessthansign]b[greaterthansign] Floor[lessthansign]/b[greaterthansign] - 5ft x 7 ft rug over birch floors. [lessthansign]b[greaterthansign] Ceiling[lessthansign]/b[greaterthansign] - Left naked - Experimented with GIK 244 up between the peaks but it made the room a bit too lifeless.
TRANSDUCER :: Horning Aristotle Zigma Ultimate
The little hornings with the upgraded drivers. The jump to Dx-65 lowthers keeps me from bringing out my Quad ESL 57's from the closet.

Left speaker is 19 inches (inside corner) from front wall and 36 inches from sloping ceiling. Right speaker is 19 inches (inside corner) from back wall and 30 inches from side wall. Listening ears are 93 inches from each tweeter. Speakers are towed in significantly to point to each outer shoulder of the listener.
AMP :: PureSound M845 Monoblocks
Grips the Hornings to make very very engaging music. It is essential to treat Speakers, Amp and room as a single voice. What maybe right for one room and speaker maybe disastrous for another.

PHONO :: Tron Seven Ultimate Phono Stage
Musically resolving. It's a Tron! 100 ohm load for MC's. Originally had a standard Tron phono ... the Ultimate adds resolution and depth (not just soundstage) to the music by a significant amount (I was fortunate to voice both at the same time before I committed to upgrading to an Ultimate)

SOURCE :: Stereo :: Raven 10.5 + Cadenza Black
The Raven Arm is a superb arm with simplicity I appreciate. Ortofon Cadenza Black is an amazing cartridge. Everytime I want to move up the ladder and spend stupid money, I listen to my system and it tells me otherwise!
Added a Shun Mook Reference MC cartridge to the 10.5 arm. This is a very special cartridge. Great on mono records and bad records and is a good dollop more musical than any cartridge that has been through my system so far.
POWER :: A collective effort
Living in the heart of Denver, I have some really crappy power. Voltage varies from 114-127 regularly! Listed in order of

Jarraa, This system is well put together and is very straight forward. I imagine your sound is very beautiful,natural and has a high degree of emotional realism. You certainly must experience deep involvement with your music. Regards,
