DSE is a research project in Kyiv, Ukraine
Theoretical work and practice started in 1977
This project is one of the oldest in the post-Soviet space
STRATEGY IN DSE & PSL ACTIVITIES HAS NOT CHANGED OVER THE ALL YEARS
The company has grown rapidly since its founding and started
laboratory practice together with its division — PSL (1985)
Both projects have much in common and operate on the principle of self-government within the framework of a common ideology, each of which controls its internal structure and activities.
The DSE & PSL collections consist of:
six series — DSE
nineteen — PSL
DSE & PSL sample holders are members of the company club
To be able to communicate and receive information, it is necessary to receive
the patronage (recommendation) from people who are already in the club
Meetings are held individually or in small groups, up to three people, which allows you to devote more time and attention for everyone
Welcome owners of high-fidelity stereo systems of the highest category of complexity
Lectures, seminars, public laboratory work is not practiced!
In 2010, the first musical programs with high quality of sounding were created on technical base, from the selected components of record and reproducing, this is the series of musical programs/releases — Plus 100, Plus 100 Extra, Plus 100 Grail, Plus 100 Grail Longer, Plus 100 Platinum & Plus 100 Prime.
The tape recorders AMPEX, STUDER / REVOX are used in order to create the records.
The professional recording tapes BASF, AMPEX, SONY, 3M are used in the work.
Tape recorder corrector was created on the basis of TELEFUNKEN EF7, EF11 & AD1 tubes.
Speed of movement of recording tape (38.1cm/s and 76.2cm/s), allows obtaining the high quality sounding.
At present, all records are being tested on the control tract, consisting of harmonized components:
— Headphone — BEYER DT990PRO
— Ears Speaker — STAX SR007
— Magnifier based on the tubes — TELEFUNKEN EF12, EL11 & AD1
— АS on speakers Lowther – DX2, PM2A & PM5A (modified).
Works on creating the record (sound) start from:
1) selection of components for each track:
— CD transports
— ADC & DAC
— interconnecting cables
— recording tape recorders
— recording tapes
— optical media
2) before starting the work on each track, all components of record track are demagnetized.
Only high quality, carefully selected phonograms, which are tested on the harmonized sound systems are accepted to the work.
— sound image volume (width, depth, rear)
— rounded / spherical sound field
— sound transparency
— after-sound effects
— AFR – Amplitude frequency response
— PFR – Phase frequency response
Quantity of created musical programs is limited because of long processing chain and time of their record, as well as high coefficient of discarded phonograms (which did not pass the test-selection).
In order to create its works, PSL uses the technical base of DSE
