Kukhulu kangakanani umehluko womsindo phakathi kwamadivayisi we-Bluetooth? Sibeka lo mbuzo esivivinyeni usebenzisa la madivaysi amahlanu:
- Ukudluliselwa kwe-Mass Fidelity
- I-Audioengine B1
- I-Arcam miniBlink
- I-Arcam iblink
- I-DBPower BMA0069 isamukeli se-Bluetooth

Ingabe Abamukeli be-Bluetooth bangabe bahluke ngempela?
Uma unayo i-smartphone, ithebhulethi, noma ikhompiyutha yekhompyutha yesimanje, unayo idivayisi ye-Bluetooth. Kungenzeka ukuthi unomculo othile ogcinwe kukho, futhi ngokuqinisekile ungakwazi ukusakaza umculo nokuxoxa ngezinhlelo nge-Intanethi.
I-gear ephezulu yokulalelwayo iqala ukufaka izimpendulo ze-Bluetooth. Akumangalisi ukuthi izinkampani ezithile manje zenza lokho ezikubhekisela kuzo njengezimvume ze-Bluetooth ze-audiophile-grade.
Ngaphandle kweyunithi ye-DBPower, zonke lezi zamukeli zithuthukise izinkinobho zokuguqula idijithali kuya ku-analog . Amayunithi amathathu (konke kodwa i-DBPower kanye ne-miniLink) anezingqinamba ezinzima kakhulu ze-aluminium, kanye nama-antenna angaphandle okufanele athuthukise ukwamukelwa kweBluetooth kanye nobubanzi. Bonke kubo ngaphandle kokuthi i-DBPower ine-decoding ye-AptX .
Umthombo womculo osetshenzisiwe waba amafayela ama-MP3 angu-256 kbps kusuka efonini ye-Samsung Galaxy S III e-Android (ehlongozwayo). Lolu hlelo lwaluyizikhulumi zeRevel F206 kanye nesandulela se-Krell Illusion II kanye nama-amps amabili ama-Krell Solo 375.

Abamukeli be-Bluetooth: Izivivinyo Zezinga Lomsindo
Ukungafani phakathi kwalezi zingxenye kuncane kakhulu. Ngaphandle kokuba ungumculi ojulile womsindo, cishe ngeke uzibone futhi cishe ngeke ukhathalele ngisho noma wenza. Kodwa-ke, kwakukhona ukungafani okucashile.
Mhlawumbe i-best of the group yayingu-Arcam rBlink-kodwa nge-caveat. Kwakuyimodeli yodwa eyathola amanothi amaningi okulalela, futhi yodwa eyazihlukanisa ngempela nepakethe. Ukufuduka-ikakhulukazi ukuhamba okuphansi, okuba nomthelela omkhulu ekuzweni umsindo namazwi okudlala-kuzwakala okujabulisayo futhi okuningiliziwe. Lona uhlobo lwama-audiophiles abakhathalelayo.
Kodwa isithombe se-rBlink stereo sibonakala sondela ngakwesobunxele. Isibonelo, izwi likaJames Taylor elibukhoma bokuthi "Shower the People" lihambe lisuka endaweni efile kuya endaweni eyodwa noma ezimbili kuya kwesobunxele besikhungo. Kulinganiswe ne-analyzer audio ye-Neutrik Minilyzer NT1, i-rBlink yayinezinga lezinga lesiteshi, kodwa kuphela ngu-0.2 dB. (Ezinye zivela ku-0.009 dB ye-Audioengine kuya ku-0.18 dB ye-DBPower.)
Kwakungabonakali ukuthi i-0.2 dB yayizokwenza ukungafani kahle kwesiteshi okuzwakalayo, kodwa yatholakala ngendlebe futhi ingalinganiswa. Umehluko phakathi kwe-rBlink, amanye amayunithi, nesidlali se-Panasonic Blu-ray esixhunywe ngedijithali ku-prere Krell ibonakala njalo.
Ukungalingani kwesiteshi kungase kube nomthwalo wemibono ye-rBlink enemininingwane engcono kakhulu ehamba phambili.
I-Mass Fidelity Relay ne-Audioengine B1 ziboshelwe ikhwalithi ephilile. I-B1 ibonwe jikelele ngokubanzi; I-Relay yangempela yayizwakala ilula phakathi maphakathi kodwa i-sibilant encane ehamba phambili. Nakulokhu, lokhu kwahlukana kwakungcolile kakhulu;
I-Arcam miniBlink kanye neyunithi ye-DBPower izwakala ngokubambisana kunabanye.
Ukuthuthukiswa okuphezulu okunikezelayo okuthuthukisiwe
Ingabe kukhona isizathu esihle sokuchitha okuningi kumamukeli we-Bluetooth ophezulu? Yebo, esimweni esisodwa: uma isistimu yakho yomsindo inomshini ophezulu we-digital-to-analog noma isampula ye-digital ene-DAC ephezulu eyakhelwe ngaphakathi.
Kokubili i-Arcam rBlink ne-Audioengine B1 inemiphumela yedijithali (i-coaxial ye-rBlink, i-optical ye-B1) evumela ukuba uhambise ama-DAC abo ngaphakathi. Lezi zunithi zazifaniswa ngokuxhuma kokubili iziphumo zabo ze-analog nezedijithali ku-prerempre Krell; ne-digital connection, lokho kwakusho ukuhamba nge-DAC yangaphakathi ye-DAC.
Umehluko wawulula ukuzwa. Ukusebenzisa izakhi ze-digital units, i-treble yayishisa, amazwi ayenama-sibilance encane, amathrekhi amathrekhi ayezwakala kancane kancane, futhi imininingwane efihlakeleyo ephezulu yayikhona kakhulu futhi iyinkimbinkimbi ngesikhathi esisodwa. Noma kunjalo, ukungalingani kwesiteshi kuzwiwe nge-rBlink kwasala ngisho nokuxhumeka kwedijithali. Strange.
Awunayo Imishini Ephezulu?
Uma ungenalo i-DAC noma isampula se-digital, kunzima ukwenza icala ngokuthenga i-receiver ye-Bluetooth ephezulu, ngaphandle uma uzimisele ukukhokha okuningi ngokuthuthuka okucashile kumgangatho wezwi (okuyinto enengqondo ephelele into okufanele uyenze uma unayo ibhakede futhi uzokwazisa ukuthuthukiswa okuncane). Ungase futhi ukhuphuke phezulu uma ukhetha i-nice, i-aluminium eqinile engxenyeni esikhundleni se-little pc plasticky efana ne-DBPower BMA0069.
Umsebenzi Olungcono Uma Unayo I-DAC noma I-Preamp
Kodwa uma unesidingo esihle se-DAC noma isampuli esiphezulu se-digital, cishe uzothola umsindo ozwakalayo ngokusebenzisa isamukeli se-Bluetooth ngokukhipha kwedijithali. Ngenxa yezindleko zayo eziphansi futhi okubonakalayo kwe-digital, i-Audioengine B1 ibonakala sengathi isebenza kahle kakhulu lapha.
