- Hybrid Class AB Amplifier
The HA-2SE's power amplification circuit for the headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The discrete transistor output stage uses hand-picked and matched parts. The output transistors are biased to operate in their most linear range for the critical small signal, and deliver their full potential when power is required. - Clean Signal Path
There is no DSP (Digital Signal Processor) in the HA-2SE. Volume control is operated by a combination of the DAC chip's internal digital volume control and an analog potentiometer (the familiar volume knob). Bass boost is performed by pure analog audio circuits. By avoiding re-digitizing the audio signal for volume adjustment or bass boost, the HA-2SE provides a clean signal path for the audio. - Audio-In and Line-Out
The HA-2SE has a 3.5 mm Audio-In port to support portable music players that do not have a USB-compatible digital output. While the HA-2SE is used with one of its USB digital input ports, the 3.5 mm jack acts as Line-Out for the USB DAC.
- ESS Sabre32 Reference DAC
The DAC is one of the most important components for digital audio playback. The ES9028-Q2M DAC chip used in the HA-2SE is the latest flagship mobile DAC developed by ESS Technology. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented performance for mobile applications. 
Hi-fi Sound Meets Style
- Asynchronous USB DAC
By bypassing the smartphone's built-in DAC and headphone amplification circuit that are often cost-constrained, the HA-2SE turns a smartphone into a high performance digital audio player. The asynchronous USB DAC input of the HA-2SE also works with PC and Mac computers to replace the built-in sound card and support high-resolution audio playback with PCM up to 384 kHz 32-bit and DSD up to 12 MHz (DSD256). - Bass Boost
For those who like a bit more punch and impact with their music, the HA-2SE offers a Bass Boost function. With Bass Boost off, the HA-2SE delivers a ruler-flat frequency response; with Bass Boost on, the HA-2SE adds force and impact to the sub-bass region without muddling the important mid- to high-frequency bands. - Two Gain Settings
The HA-2SE offers two gain level settings for optimal headphone matching. The High Gain mode is capable of driving large power-hungry headphones, delivering up to 300 mW into 16-Ohm headphones. The Low Gain mode is intended for sensitive In-Ear Monitor type earphones.

Casti OPPO PM-2
Oppo PM-1 casti magnetice plane ofera un mod de gandire diferit despre acest tip de tehnologie. PM-2 sunt caracterizate de o combinatie intre naturalete, dinamica, calitate a sunetului, mandrie de a le purta si o masa redusa. Ele sunt rezultatul mai multor ani de cercetare si dezvoltare ale unei echipe de ingineri pasionati de audio-acustica, oameni de stiinta in chimie si stiinta materialelor si audiofili. Tehnologia este definita de o gama larga de solutii inovatoare care ofera performante exceptionale.
Avantajele tehnologiei magnetice plane se bazeaza pe faptul ca intr-un driver plan sunetul este generat de o diafragma foarte subtire si usoara sunetul fiind deasemenea condus in intreaga suprafata radiant in mod egal. Sunetul intra in ureche ca o unda plana numit ERP (ear reference point − punct de referinta al urechii) cu toate componentele spectrului fazate. Un driver dinamic tip al unei casti normale este caracterizat de diferente de faza si neregularitati si deci de coerenta din pricina varfurilor si a impulsurilor sonore foarte scurte. Un driver magnetic plan are si avantajul unei impedante pur rezistive. Acesta are un model conductiv plat fara nicio componenta inductiva care elimina inductanta legata de distorsiunile IM comune castilor dinamice. O incarcare rezistiva asigura deasemenea ca orice amplificator va induce in casti un semnal fara schimbari in balanta spectrala.
Oppo integreaza unic mai multe inovatii si metode proprietare dezvoltate de-a lungul anilor uzitand cele mai recente descoperiri in tehnologia materialelor si tehnicilor de fabricatie. Rezultatele acestor cercetari s-au concentrat pe eliminarea problemelor care afecteaza adesea castile magnetice plane si anume, sensibilitatea scazuta, masa mare, stabilitatea scazuta a diafragmei si fiabilitatea si astfel a creat o tehnologie noua in domeniu. Castile magnetice plane Oppo utilizeaza un magnet FEM optimizat cu magneti de inalta energie din Neodymium. O mare diafragma plana ovala este pozitionata intr-un camp magnetic uniform. Diafragma este constituita din conductori plati organizati ca o spirala pe ambele parti ale unui film subtire de polimer. Sistemul magnetic si modul de aranjare al conductorului sunt optimizate pentru o putere maxima de conducere ceea ce se reflecta in sensibilitate iar forta aplicata pe suprafata radianta ofera coerenta. Diafragma este formata din 7 straturi extrem de fine fiecare avand importanta sa in performanta, fiabilitate, longevitate.
Aceste avantaje ale inaltei rezolutii in tehnologia castilor magnetice plane Oppo cat si design-ul avansat asigura un sunet deschis, transparent, dinamic, cutonuri foarte echilibrate si distorsiuni mici, luand nastere un produs care comunica fiecare nuanta si intentie a compozitorului si producand un inalta angajament emotional pentru audiofil. Cu finaisarea sa industriala dar in acelasi timp orientata clar spre detaliu, PM-2 se incadreaza perfect atat in caminul sau camera audifilului cat si cu peisajul urban si un dispozitiv portabil High-End.
Pentru Boxe:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate.
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.
Pentru Amplificatoare, DAC-uri, Preamplificatoare, Receiver Stereo & Home Cinema, Surse digitale audio-video:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
Pentru cabluri:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
