Kev Xeem Topping E30 ntawm cov peev txheej sib txawv
Topping yog renowned rau tshaj tawm lub suab ntsuas ntawm txhua lub cuab yeej nws ua rau nws lub vev xaib. Lawv tau tsim los siv lub Suab Precision APx555 lub suab ntsuas. Tsis tas li ntawd, cov ntaub ntawv no tuaj yeem pom hauv phau ntawv tshwj xeeb uas tuaj nrog lub cuab yeej.
Ua ntej tshaj plaws, qhov no qhia tias peb tuaj yeem saib cov yam ntxwv tiag tiag ntawm lub cuab yeej. Tsis muaj kev cia siab rau cov chaw tsim khoom cov lus cog tseg, thiab tsis poob rau ntau yam kev dag ntxias thiab kev dag ntxias. Ntxiv mus, Topping cov khoom siv feem ntau raug tshuaj xyuas ntawm cov peev txheej zoo li ASR (audiosciencereview). Qhov twg Audio Precision APx555 lub suab ntsuas yog siv rau kev ntsuas.
Raws li kev ntsuas ntsuas ntawm ob lub chaw tsim khoom thiab ASR lub vev xaib, cov lus xaus hauv qab no tuaj yeem kos:
| Lub teeb liab zaus rau kev ntsuas, kHz | 1 |
| Tso zis zog, Vrms | > 2 |
| Tag nrho Harmonic Distortion + Suab nrov (THD + N),% | <0.0003 |
| Teeb liab rau suab nrov piv (SINAD), dB (raws li ASR) | ~ 114 |
| Teeb liab rau suab nrov piv (SNR), dB (los ntawm cov chaw tsim khoom) | 121 |
| Dynamic ntau yam, dB | ~ 118 |
| Distortion-free range (multitone), me ntsis | 20-22 |
| Jitter, dB | <-135 |
Lub jitter thaum txuas ntawm S / PDIF interface yog siab dua me ntsis. Txawm li cas los xij, qhov siab tshaj plaws yog ntawm -120 dB, uas tsis yog qhov tseem ceeb.
Nta ntawm DAC Topping E30
Lub ntsiab feature ntawm Topping E30 yog lub xub ntiag ntawm digital S / PDIF inputs ntawm tus qauv "neeg siv khoom" interfaces. COAX (RCA, coaxial) thiab TOSLINK (optical), uas tso cai rau koj txuas txhua yam khoom siv nrog cov zis tawm rau nws. Los ntawm TV thiab media player mus rau qub CD player los ntawm 80s.
Lwm feature yog lub built-in preamplifier, uas tso cai rau DAC txuas ncaj qha mus rau lub hwj chim amplifier. Txawm hais tias, feem ntau, qhov no yog siv los kho lub suab los ntawm cov chaw taws teeb tswj. Yog tias tsis muaj ib qho ntawm "tag nrho" amplifier, uas feem ntau siv los ntawm cov neeg nyiam suab paj nruag.
Qhov no feature muaj nws drawbacks. Namely, qhov poob ntawm lub peev xwm ntawm cov zis teeb liab. Txawm li cas los xij, qhov no tsis txhais hais tias kev ua tsis zoo ntawm lub suab zoo. Rau txhua yam yuav nyob ntawm qhov xwm txheej tshwj xeeb thiab kev teeb tsa ntawm lub kaw lus.
AK4493 microcircuit muaj nyob rau hauv board 6 lub suab lim rau PCM thiab 2 rau DSD los pab hloov cov ntsiab lus suab me ntsis.
Hmoov tsis zoo, cov haujlwm no tsuas yog muaj los ntawm cov chaw taws teeb tswj. Thiab qhov no yuav zoo li tsis yooj yim rau cov neeg uas muaj DAC ib sab ntawm lub computer lossis laptop.
Analogs DAC Topping E30
Qhov sib txawv tseem ceeb ntawm Topping E30 thiab cov khoom siv pheej yig dua yog qhov muaj S / PDIF inputs xws li hauv "classic" DAC. Piv txwv li, hauv Topping D10s qauv, digital interfaces ua raws li cov zis. Ntawd yog, cov cuab yeej no tuaj yeem siv los ua USB converter. Rau cov teeb liab ua hauv S / PDIF rau kev pub mis rau lwm DAC. Txawm hais tias, muaj kev tsis ntseeg tias tus neeg siv zoo tib yam yuav xav tau nws. Lub Topping D10s yog suav tias yog USB DAC nkaus xwb. Zoo li ntau yam khoom siv rau tus nqi qis dua. Yog li, yog tias muaj S / PDIF inputs tseem ceeb, ces E30 yog qhov kev xaiv zoo.
Raws li ib qho piv txwv los ntawm shenzhenaudio.com (cov cuab yeej raug nqi qis dua $ 150), XDUOO MU-601 DAC siv ES9018K2M mobile nti. Tab sis tsis muaj cov khoom siv digital (tsuas yog coaxial los ntawm cov zis). Lub FX Audio D01 DAC yog twb ua raws li ES9038Q2M nti tam sim no. Muaj nyob rau hauv lub nkoj txais Bluetooth nrog kev txhawb nqa rau LDAC codec thiab lub mloog pob ntseg ua suab nrov. Ntawm no peb twb muaj tag nrho "sib txuas".
Tab sis xav txog DACs los ntawm lwm lub tuam txhab, koj yuav tsum tau them sai sai rau kev siv lwm yam khoom. Ntxiv rau, cov txheej txheem sib txawv ntawm Circuit Court, thiab, raws li, rau lwm qhov ntsuas. Ntxiv mus, nws tsis zoo li qhov sib xyaw ua ke rau tib tus nqi yuav tsim lub suab ntawm qib no, tom qab tag nrho, nws muaj cov ntawv thov sib txawv.
Lwm qhov nthuav yog Sanskrit 10th MKII los ntawm lwm lub npe nrov Suav, SMSL. Nws yog raws li tib AK4493 nti. Tab sis nws poob (raws li ASR), nyob rau hauv kev sib piv nrog multitone thiab jitter, tshwj xeeb tshaj yog nyob rau hauv S / PDIF. Leej twg yog tus saib xyuas S / PDIF teeb liab kev ua haujlwm tseem yog qhov tsis paub. Rau qee qhov laj thawj, cov chaw tsim khoom tsis qhia qhov no. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias cov cuab yeej no kuj muaj cov chaw taws teeb tswj. Muaj hom preamp thiab built-in suab lim. Tsis yog tus qauv tsim, tsis yog rau txhua tus. Lub vijtsam yog me ntsis.
