Description

I just finished building a dedicated listening room in my new apartment. It took me one year and a half to complete, but it was well worth the wait. I simply love it.

The room size is 14 x 19 x 8 feet.

The room was designed by a company that specialises in acoustic design. Not the popular Rives Audio, since I live in Europe and that would increase the costs of the Level 3 project well past $10k mark, but a reputable local company.

The room acoustics was was first designed in a digital domain and then improved upon with the real world measurements taken during all stages of construction work.

The room is soundproof and - among other things - features soundproof windows, double doors and 11" thick double walls. The measured noise level inside the room is 26dB during the day (measured during rush hours, at 16:00), so it is almost dead quiet.

The room has two dedicated lines, each rated 20A @ 230V, one for analog and one for digital gear. All cables, circuit breakers and mains outlets are of audiophile quality.

I have also added an ultra quiet (22dB) A/C.

Components Toggle details

    • MSB DAC IV Signature Plus
    MSB DAC IV Signature with Diamond Power Base - replaced the dCS Scarlatti, which served me as my reference for the past 3 yaers.
    • MSB S200
    Fully balanced 200 Watt stereo amplifier. Class A, Zero Negative Feedback design. Fluid, palpable, a bit on the warm side of things. An amazing piece.
    • Magico S5
    New addition to the system. Replaced Wilson Sasha speakers.
    • MUSA S21T USB
    Computer based transport with SOtM PCIe USB card, SOtM sata filter, fanless PSU, fanless i5 CPU, SSD, 8GB RAM and Synology 2x2TB NAS. Running Win 7/64 with Jriver and Jplay.
    • AudioQuest WEL Signature
    Replaced Tara Labs The RS-1 interconnects.
    • AudioQuest Diamond USB
    USB cable.
    • Shunyata Anaconda Z-Tron
    A new model from Shunyata. Replaced van den Tara Labs RS-1 cable.
    • Shunyata Anaconda CX
    I have two of those, powering Dart and dCS.
    • Pure Power 2000
    Battery powered AC Regenerator.
    • Finite Elemente Pagode Master Reference HD09
    Top of the range component stand from Finite Elemente, with their resonator technology (3 used). I favour those over a 4-tier Pagode rack, since they do not interfere with soundstage when placed between the speakers.
    • Finite Elemente Ceraballs
    I have two sets placed under my speaker cables. Very unussual location, I agree, but works a treat.
    • Finite Elemente Cerapuc
    I have two sets placed under my speakers. A simply stunning improvement in low-level detail retrival and microdynamics. Worth every penny !
    • HMS Energia SSDB mains outlets
    Two of those finish off my two, 230V/20A, dedicated power lines.
    • AHP Klangmodul 3+
    Audiophile circuit breakers. Gold plated, solid copper contacts. Each of the two dedicated power lines has his own breaker.
    • ACS Diffusors
    Diffusors made by german company Acoustic Control Systems. I have 3 sets of those, one on the rear wall and two on the side walls. As you can see on the pic, the whole part of the rear wall, to which the diffusor is attached, pertrudes 12" into the room.
    • Custom absorbers
    The whole room is fitted with custom absorbers, tuned to specific frequencies. The pic shows one of the six absorbers fitted to the front wall. If you look carefully, you wil notice, that there is an MDF plate with lots of small holes fitted inside, which divides the internal volume of the absorber into two smaller chambers. The sound enters the traps by the front gaps, goes to the first empty chamber and then through the holes to the next chamber, where it can dissipate in a mineral fiber (not fitted on this pic).
    • Custom diffusors
    Set of 5 custom diffusors fitted over the listener's head.
    • RT-60 curve
    This is the RT-60 curve of my room. Black trace is our target curve, blue one is base curve (empty room, no acoustic treatment, no floor), red curve shows how the room responded after ACS diffusors, wooden floor and sand stone were added. Green curve is the most recent one. It is still not perfect, but we are working on it.
    • Room Frequency Response curve
    Room Frequency response. Quite nice if you ask me :-)
    • Daikin ultra quiet A/C unit
    Daikin A/C split system replaced McQuay unit. The difference in noise levels generated by those two units is staggering. Daikin is so quiet (22dB) that you can barely hear it from the listening chair. There are CD-players that generate more noise than this ! The other outstanding feature of this unit is that it can work when outside temp drops to 10'F - so it can be used during winter too.

Adam,

Sophia 2 is an excellent choice. IMHO it is the best Wilson speaker in terms of value for money. I also like its sonic signature more then W/P8s for example.
In fact I will probably order one pair myself! Why? After listening to many expensive speakers in last 14months I did not find any that is much better then Sophia2 but, most of them were costing several times more... Recently, I audition one $50K speaker that did not sound as good as Sophia2. Of course Wilson heritage is another very welcome thing.

Enjoy your Sophia2s, they are indeed excellent speakers...
