Description

In my experience, the most important thing is the best marriage between room and speaker. Someone laughed at us by ear, I followed the rules of Jimmi Smitth and Acustica Applicata, also using the specific software.
Soon I will also add the graphs to explain everything.

    • Room 22x17x8
    In my experience, the most important thing is the best marriage between room and speaker. Someone laughed at us by ear, I followed the rules of Jimmi Smitth and Acustica Applicata, also using the specific software.
    Soon I will also add the graphs to explain everything.
    • Acustica Applicata AudioQualityTest
    Acustica Applicata AUDIO QUALITY TEST, software for room analysis.
    I start by dividing the walls into 3, 5 and 7; I tested the acoustic response with the listening point in the vertex of the isosceles triangle; on the initial indications I made other tests by moving the speakers by 10cm, and then restoring more and more (5 and 2.5 cm).
    step 1: acoustic response of the room in the chosen point where to position the speaker.
    step 2: polyurethane treatment of the rear corners and bookcase in the center of the rear wall.
    step 3: treatment with DAAD in points C and F, Halifax in D.

    • T-Audio (G. Trifirò, Messina, Italy) PrePhono Reference
    The tubes used in this project are a pair of 12AX7 or ECC83 NOS, as the first gain stage in MC, the second stage is made with the help of a pair of 6922 or ECC88 always NOS with the attached passive RIAA network connected at the pre-final stage of 12AT7 or ECC801S.
    Last stage in current but with hybrid technology operating in pure Class A is made with an excellent Triode of the Siemens CCA series, half per channel that drives a pure class A polarized stage of high current Mosfet, ensuring an output level sufficient to drive any preamp stage with an impedance value of approximately 10 Ohms per channel.
    All power supply stages with a solid-state electronic stabilization system differentiated for each single section and gain stage with an attached inductive capacitive load (in order to improve the signal-to-noise ratio and consequently the resolution in terms of timbre and dynamics).
    Separate power section.
    • Counterpoint SA-5000
    Upgraded by M. Elliot and resurrected by G. Trifirò!
    • Accuphase A-50v

You have put together a very nice system.  I like your approach.  Here in the U.S. where I live, Pass Labs is close to where I live, so I use their amp and preamp. But after several phono amps, I finally bought a tube phono, the Herron Audio.  It is great, and it can be configured a hundred different ways.  

I see you have done some room treatment.  Great that you are doing that.  I'm not familiar at all with the tools you used.  Are you satisfied?  Are you finished with treatment yet?   I am in the middle of treating my room 22' x 12' x 9'  So far, I've done extensive corner treatments, plus a combination of quadratic diffusion and absorption on the entire rear wall.  No side wall or front wall yet, and no ceiling treatment yet.  I haven't figured out exactly how I should treat those surfaces, so I'm waiting.
