Bluetooth Receiver Puas Tiag Yeej Sib Txawv Zoo?
Yog tias koj muaj smartphone, ntsiav tshuaj, lossis lub computer tsis ntev los no, koj muaj Bluetooth khoom. Koj yuav muaj qee lub suab paj nruag khaws cia rau hauv nws, thiab koj tuaj yeem kwj suab paj nruag thiab tham nrog cov kev pab cuam hauv Internet.
High-end audio iav pib nrog cov neeg siv khoom siv Bluetooth. Nws tsis xav paub txog qee cov lag luam yog tam sim no ua li cas lawv xa raws li cov neeg siv suab audiophile-qib Bluetooth.
Tsuas yog cov chav tsev DBPower, tag nrho cov ntawm cov receivers tau hloov cov chips digital-rau-analog converter . Peb ntawm cov koog (tag nrho tiam sis DBPower thiab miniLink) muaj hnyav txhuas nruj, zoo li sab nraud antennas uas yuav tsum txhim kho Bluetooth txais tos thiab ntau yam. Tag nrho lawv tsuas yog lub DBPower muaj kev xoom cim aptX .
Lub suab paj nruag siv tau yog 256 kbps MP3 ntaub ntawv los ntawm ib tug Samsung Galaxy S III Android xov tooj (uas yog aptX-txawm peem rau). Lub kaw lus yog ib lub Revel F206 tham nrog Krell Illusion II preamp thiab ob tug Krell Solo 375 monoblock amps.

Tej zaum qhov zoo tshaj plaws ntawm pawg yog Arcam rBlink-tab sis nrog ib lub caveat. Nws yog tib tug qauv uas tau txais ntau yam kev sau ntawv, thiab tsuas yog ib qho uas qhia qhov tseeb ntawm nws tus kheej xwb. Lub treble - tshwj xeeb tshaj yog cov treble tsawg dua, uas muaj cov nyhuv loj heev rau lub suab ntawm cov suab lus thiab cov yeeb yam ntawm lub suab paj nruag-suab zoo dua me ntsis thiab ntxaws. Qhov no yog qhov zoo tshaj plaws ntawm cov neeg tuaj yeem saib xyuas kev xav.
Tab sis rBlink duab tso suab zoo li mus rau sab laug.

Ntsuas nrog ib Neutrik Minilyzer NT1 suab analyzer, rBlink muaj ib theem tsis raws cai, tab sis tsuas yog 0.2 dB xwb. (Lwm tus ntawm 0.009 dB rau Audioengine mus rau 0.18 dB rau DBPower.)
Nws tsis zoo li ntawd 0.2 dB yuav tsim tau ib txoj hlua dig muag yooj yim, tab sis nws tau kuaj tau los ntawm pob ntseg thiab yuav ntsuas tau. Qhov txawv nruab nrab ntawm rBlink, lwm pawg, thiab ib tug neeg ua haujlwm Panasonic Blu-txoj kab sib txuas nrog dig muag rau Krell preamp qhia nws tus kheej txhua lub sijhawm.
Cov dej tsis txaus yuav yog lub luag hauj lwm rau kev xaav ntawm rBlink muaj qhov zoo dua qis dua treble.
Kev Fidelity Relay thiab Audioengine B1 tied rau suab zoo. Lub B1 suab marginally smoothest txhua yam; Cov Kev Txawj Ntse tau ua suab nrov nyob hauv qhov nruab nrab tab sis sib sib zog nqus sib sib zog nqus hauv lub treble. Ib zaug ntxiv, cov kev txawv no sib txawv heev;
Lub Arbar miniBlink thiab DBPower chav ua suab npe dua me ntsis ntxiv dua lwm tus.
High-End Muab Kev Txhim Kho Dua
Puas muaj ib qho laj thawj zoo rau kev siv ntau dua rau tus txais txiaj ntsim ntawm Bluetooth siab dua? Tau, nyob rau hauv ib qho teeb meem: yog tias koj lub suab muaj qhov zoo tshaj digital-to-analog converter los yog digital preamp nrog ib tug zoo DAC built hauv.
Ob lub Arcam rBlink thiab Audioengine B1 muaj cov kev tawm (coaxial rau rBlink, kho qhov muag rau B1) uas cia koj hla lawv cov DACs. Cov koog no tau muab sib piv los ntawm kev siv ob qho lawv cov analog thiab digital tawm mus rau Krell preamp; nrog cov kev sib txuas digital, uas tau nkag mus los ntawm Illusion II preamp lub DAC.
Qhov txawv yog qhov yooj yim los mloog. Siv cov kev tawm ntawm cov digital, cov treble tau zoo dua, lub suab tau sib sib zog sib sib zog nqus, cov twj paj nruag ua suab nrov, thiab cov ntsiab lus tseem ceeb heev dua tuaj yeem tshwm sim dua tib lub sijhawm. Txawm li cas los xij, cov channel tsis txaus siab hnov nrog rBlink tseem nyob nrog cov kev sib txuas digital. Coj txawv txawv.
Tsis Muaj Cov Khoom Siv Qib Siab?
Yog tias koj tsis muaj DAC lossis cov digital preamp, nws yog ib qho nyuaj ua rooj plaub rau kev yuav khoom txais Bluetooth siab tshaj plaws, tshwj tsis yog tias koj txaus siab them ntau heev rau kev txhim kho zoo heev hauv suab zoo (uas yog ib qho tsim nyog tsim nyog yam ua yog tias koj muaj cov bucks thiab yuav zoo siab rau kev txhim kho me me). Tej zaum koj kuj tseem yuav mus high-end yog tias koj xav tau ib qho khoom zoo, khoom txhuas uas tsis zoo, es tsis txhob siv cov khoom me me zoo li DBPower BMA0069.
