Toote info

Uniting source components with power amplifiers, it must perform the critical functions of impedance matching, level balancing and volume control while maintaining perfect signal accuracy and channel integrity. Adding nothing. Taking nothing away.

While the perfect preamplifier continues to be a technical challenge for audio designers, we believe the 525 gets closest to the ideal.

Perfect volume control 
The 525 owes much to the design of the range-topping soulution 725 Preamplifier. It uses the same volume control which ingeniously combines the smooth fingertip control of variable resistors with the precision and stability of fixed resistor networks. For the 525 we’ve chosen the best performing Vishay Dale resistors with relays of the utmost quality. The end result is volume control that is finely adjustable in 95 steps of 1 dB each, with no perceptible switching clicks. Truly the best of both worlds.

Advanced Switching 
Input selection too uses very high-quality relays. The design – which switches ground as well as signal connections – ensures that only the selected input is connected through to the 525 electronics, the remainder being isolated. By buffering all signals immediately after the input, the 525 presents only a minimal load to source devices. Both balanced and unbalanced inputs are available.

Dual-mono construction 
As few components as possible in the signal path speak for an unbalanced circuit concept. In this case, the lowest possible stereo conversations can only be achieved with a consequent dual-mono design. The analogue circuits and the associated power supplies of the left and right channels are physically separated from one another and are additionally decoupled with filter networks.

Level and phase correct with all loads 
An ideal preamplifier like the 525 maintains perfect level accuracy and phase accuracy regardless of load. But measured values are only part of the story. Ultimate sound quality should always be the first priority. At no time should distortion, noise or hum be allowed to colour the music.

Perfect power
In order to drive the longest of signal cables, the output stage of a preamplifier must be sufficiently power­ful to do the job. The 525 employs a powerful, very fast and ultra-wide (2 MHz/– 3 dB) output stage that can drive long cables with ease. We team that with a similarly robust, high specification switched-mode power supply which features high-precision and extremely low-noise linear control circuits. Backed by more than 400,000 μF of storage, the power supply of the 525 provides virtually unlimited pulse power with indiscern­ible levels of noise.

Audiophile transparency 
Musical transparency is pre-eminent in the 525. Colouration is simply not a factor. Control too is at the 525’s heart: stereo imaging precision is exemplary while sound sources appear perfectly focused on the sound stage. Once you audition the 525 you will come to understand the true nature of sound and the importance of the right preamplifier in achieving it.

Brändist

Soulution

Soulution kuulub korporatsioonile Spemot, mis asub Šveitsi linnas Dullikenis. Spemot on autotööstuses ja muudes rakendustes kasutatavate elektrooniliste seadmete ja elektrimootorite väljakujunenud disainer ja tootja, sealhulgas professionaalsed toitlustusseadmed. Ettevõttel on suured kogemused innovaatiliste kohandatud lahenduste osas, mis vastavad klientide konkreetsetele vajadustele. 

Esmaklassilist heli taasesitava audiotehnika brändi Soulution lõid Spemoti kaks tegevdirektorit Cyrill Hammer ja Roland Manz, mõlemad kirglikud tipptasemel audioharrastajad. Mõlemad on ajakirja Hi-Fi & Records pikaajalised Šveitsi turustajad. Pärast USA ja Jaapani tootjate toodetud tippvõimendite omamist ja kuulmist otsustasid nad seada endile väljakutse ja luua helitoodete pere, mis seaks uue ja veelgi kõrgema võrdlusaluse. 

Nagu ülemaailmsed audioajakirjade ülevaated Soulution kohta kinnitavad, on Hammer ja Manz oma eesmärgi saavutanud.

 Disain

 Soulution-i silmapaistvaid heliomadusi peaks toetama ka korpuse kujundamine, nii visuaalselt kui ka konstruktsioonilt. Nende suuruse tõttu oli selge, et nad peavad olema optimaalselt integreeritavad kuulamis- / elutuppa, et neid saaks nautida mitte ainult helilise ilu, vaid ka visuaalse välimuse tõttu. Korpuse kujunduse väljatöötamine viidi seetõttu läbi sama ettevaatlikult ja professionaalselt kui elektroonika väljatöötamisel. Esitati mitmeid ettepanekuid, mis vastasid nii stabiilsuse kui ka soojuse hajumise tehnilistele nõuetele, samuti projekteerimisnõuetele.

 Disainiauhinnad

 Pingutus on end ära tasunud. Rahvusvahelised disainižüriid tunnustasid Soulution tooteid ajatu ja elegantse disaini eest mitu korda.
