Qhov sib txawv sonic loj npaum li cas ntawm Bluetooth li? Peb muab lo lus nug no rau kev sim siv tsib yam khoom siv nram qab no:
- Mass Fidelity Relay
- Audioengine B1
- Arcam miniBlink
- Arcam rBlink
- DBPower BMA0069 Bluetooth receiver
Puas Bluetooth Receivers tiag tiag suab txawv ntawm ib leeg?
Yog tias koj muaj lub xov tooj smartphone, ntsiav tshuaj, lossis lub khoos phis tawj tsis ntev los no ces koj muaj lub cuab yeej Bluetooth. Koj yuav muaj qee cov suab paj nruag khaws cia rau ntawm nws, thiab koj tuaj yeem tshaj tawm suab paj nruag thiab podcasts hauv Internet.
High-end suab iav tau pib koom nrog Bluetooth txais. Nws tsis yog qhov xav tsis thoob tias qee lub tuam txhab tam sim no ua qhov lawv xa mus ua audiophile-qib Bluetooth receivers.
Tshwj tsis yog rau chav tsev DBPower, tag nrho cov neeg txais no tau hloov kho digital-rau-analog converter chips. Peb ntawm cov chav nyob (tag nrho tab sis DBPower thiab miniLink) muaj cov ntaub ntawv txhuas hnyav, nrog rau cov kav hlau txais xov sab nraud uas yuav tsum txhim kho Bluetooth txais tos thiab ntau yam. Tag nrho cov ntawm lawv tsuas yog DBPower muaj aptX decoding.
Lub suab paj nruag siv yog 256 kbps MP3 cov ntaub ntawv los ntawm Samsung Galaxy S III hauv xov tooj (uas yog aptX-nrog). Lub kaw lus yog Revel F206 hais lus ntxiv rau Krell Illusion II preamp thiab ob Krell Solo 375 monoblock amps.
Bluetooth Receivers: Sound Quality Tests
Qhov sib txawv ntawm cov chav no yog qhov me me. Tshwj tsis yog tias koj yog tus nyiam lub suab loj, tej zaum koj yuav tsis pom lawv thiab tej zaum koj yuav tsis mob txawm tias koj ua. Txawm li cas los xij, muaj qhov sib txawv me ntsis.
Tej zaum qhov zoo tshaj plaws ntawm pawg yog Arcam rBlink-tab sis nrog lub caveat. Nws yog tib tus qauv uas tau txais ntau cov ntawv mloog, thiab tsuas yog ib qho uas txawv ntawm nws tus kheej ntawm pob. Lub treble-tshwj xeeb tshaj yog lub qis treble, uas muaj cov nyhuv loj ntawm lub suab ntawm lub suab thiab cov twj paj nruag percussion-suab me ntsis cus ciav thiab meej. Nov yog yam uas audiophiles mob siab txog.
Tab sis rBlink lub tso suab duab zoo li rub mus rau sab laug. Piv txwv li, James Taylor lub suab nyob rau hauv lub version ntawm "Shower the People" tau tawm ntawm qhov chaw tuag mus rau ib lossis ob txhais taw mus rau sab laug ntawm qhov chaw. Ntsuas nrog Neutrik Minilyzer NT1 lub suab ntsuas, lub rBlink muaj qhov tsis sib xws ntawm cov channel, tab sis tsuas yog los ntawm 0.2 dB. (Lwm qhov txawv ntawm 0.009 dB rau Audioengine rau 0.18 dB rau DBPower.)
Nws tsis zoo li tias 0.2 dB yuav tsim kom muaj lub suab nrov tsis txaus ntseeg, tab sis nws tau kuaj pom los ntawm pob ntseg thiab ntsuas tau. Qhov sib txawv ntawm rBlink, lwm chav nyob, thiab Panasonic Blu-duab tshav player txuas nrog digitally rau Krell preamp qhia nws tus kheej txhua zaus.
Txoj kev tsis txaus ntseeg channel yuav yog lub luag haujlwm rau kev nkag siab ntawm rBlink muaj cov ntsiab lus qis dua-treble zoo dua.
Cov Kev Ntseeg Siab Tshaj Plaws thiab Audioengine B1 khi rau lub suab zoo. B1 suab marginally smoothest tag nrho; Lub Relay yeej suab smoother nyob rau hauv nruab nrab tab sis me ntsis ntau sibilant nyob rau hauv lub treble. Ntxiv dua thiab, cov kev sib txawv no tau hloov maj mam. Thaum kawg, Arcam miniBlink thiab DBPower chav ua suab nrov me ntsis ntau dua li lwm tus.
High-end Kev Txhim Kho Kev Txhim Kho
Puas muaj laj thawj zoo los siv nyiaj ntau dua ntawm tus txais Bluetooth siab dua? Yog lawm, hauv ib qho xwm txheej: yog tias koj lub kaw lus muaj qhov zoo tshaj plaws digital-rau-analog converter lossis digital preamp nrog DAC zoo ua hauv.
Ob leeg Arcam rBlink thiab Audioengine B1 muaj cov txiaj ntsig digital (coaxial rau rBlink, kho qhov muag rau B1) uas cia koj hla lawv cov DACs sab hauv. Cov chav nyob no tau muab piv los ntawm kev sib txuas ntawm lawv cov analog thiab digital outputs rau Krell preamp; nrog rau cov kev sib txuas digital, uas txhais tau tias mus dhau ntawm Illusion II preamp's internal DAC.
Qhov txawv yooj yim hnov. Siv cov units 'digital outputs, lub treble yog smoother, lub suab tsis muaj sibilance, percussion instruments sounded tsawg sizzly, thiab subtle high-zaus cov ntsiab lus muaj ntau tam sim no thiab ntau ilv nyob rau tib lub sij hawm. Txawm li cas los xij, qhov tsis txaus ntseeg channel tau hnov txog rBlink tseem nyob txawm tias nrog kev sib txuas digital. Qhov txawv.
kab hauv qab
Yog tias koj tsis muaj DAC lossis digital preamp, nws nyuaj rau ua rooj plaub rau kev yuav lub siab kawg Bluetooth txais, tshwj tsis yog koj kam them ntau rau kev txhim kho me ntsis hauv suab zoo (uas yog ib qho tsim nyog ua tau zoo yog tias koj muaj nyiaj thiab yuav txaus siab rau qhov kev txhim kho me me). Tej zaum koj kuj yuav mus high-end yog tias koj xav tau ib qho zoo, cov ntaub ntawv txhuas es tsis txhob siv cov yas me me xws li DBPower BMA0069.
Qhov Deal zoo tshaj yog tias koj muaj DAC lossis Preamp
Yog tias koj muaj DAC zoo lossis lub siab kawg digital preamp, tej zaum koj yuav tau txais lub suab zoo dua los ntawm kev siv Bluetooth txais nrog cov zis digital. Vim tias nws cov nqi qis dua thiab cov khoom siv kho qhov muag pom, Audioengine B1 zoo li qhov zoo tshaj plaws mus ntawm no.
