I-DAC engama-300 ee-DAC eyenza konke? Phantse.
Kubonakala ngathi zonke iimbini zeeminyaka, abaguquleli be-digital-to-analog bahamba nge-revolution. Kwiminyaka emibini edlulileyo bonke bongeze i-USB. Kwi- Rocky Mountain Mountain Audio Fest , sabona i-DAC ngaphezulu nangaphezulu - enye enye engaphantsi kweedola ezingama-400 - eyongezwa ngokukhawuleza nge-Digital Stream (DSD). Yintoni elandelayo? Mhlawumbi i-HDMI . Xa utshintshe utshintsho oluninzi, unokwenza ityala elungileyo ngokuthenga into enhle kwaye efikelelekayo kunokuba uchithe imali yokuxosha yonke into entsha. Yilapho i-V90-DAC ingena khona.
I-Faithal Fidelity yakha i-$ 299 i-V90-DAC njengenxalenye ye-V90 yayo, i-trio yexabiso eliphantsi, i-non-frills eyenzelwe abaphulaphule abazimisele ukuchitha ixesha elincinci into enhle kodwa abanqweneli ukuchitha yonke idola ngenxa ye-state-of-art.
Ipaneli yangemuva inezixhobo ezine zedijithali: i-USB engaqhelekanga, i-RCA coaxial, kunye ne-Toslink ebonakalayo. Iziphumo zisekhompyutheni ze-RCA stereo. Ipaneli yangaphambili inamandla nje kunye neenguqu zokufakelwa.
Ngoko yintoni ekhoyo? Izinto ezimbini. Enye, ukufakwa kwe-USB kwamkela iimpawu zedijithali ukuya kwisisombululo se-24-bit / 96-kilohertz; ayiyi kwamkela i-audio-res ephezulu ye-192-kilohertz, kodwa i-DAC ezininzi kwixabiso lexabiso aliyi kuba. Unokwenza u-24/192 ngokusebenzisa igalelo le coax, kodwa ukuba uthabatha ezo fayile kwi computer, uzakufuna i-adapter ye-USB-to-coax. I-V90-DAC yenza umzekelo wento yonke ukuya kwi-24/192, nangona kunjalo. Yaye ukuba unayo iifayile ezingama-24/192 kwikhompyutheni yakho, iya kudlala, kodwa ikhomputha iya kubahlalisa i-24/96. Kwakhona, i-V90-DAC ayinayo i-headphone jack, into enokuthi ungayifuni okanye ingafuni, kodwa ifunyenwe kwii-DAC ezininzi kule mihla.
Iimbonakalo
• I-USB engaqhelekanga, i-RCA coax kunye ne-2 Toslink
• Ukuphuma kwe-Stereo RCA
• Amkela iimpawu ukuya kwisisombululo se-24/192 ngokubambisana
• Amkela iimpawu ukuya kwisisombululo se-24/96 nge-USB
• Ubukhulu: 1.9 x 6.7 x 4 kwi / 47 x 170 x 102 mm

Ukusetha / iErgonomics
Akukho nto enokubaluleka apha. Xhuma kwi-wart-wart supply power supply, ulungele zonke izinto zakho zedijithali, qhagamshela i-V90-DAC kwi-preamp okanye i-receiver yakho, kwaye ube nayo. Iikhompyutha zekhomputha ze-HP, IBM kunye neToshiba endayisebenzisa kunye ne-V90-DAC yazibona ngokukhawuleza.
Ndiyithande ukulula kokuba ngumtshintshi wokukhetha endaweni yeqhosha le-DAC ezininzi ezininzi ezisetyenziselwa ukuprolela ngeenjongo. Kodwa ndinqwenela ukuba i-V90-DAC ibe negalelo langaphambili le-USB ukwenza kube lula ukuxhuma i-laptop yami.
Ukusebenza
Kwiiveki ezimbalwa, ndasebenzisa i-V90-DAC ngokwayo njengomthombo wedijithali oyintloko kwinkqubo yam, ukuxhuma kumdlali we-Panasonic Blu-ray kunye nekhompyuter yeToshiba engayisebenzisela kakhulu umdlalo wam umculo. Ndasebenzisa i-amp ye-Krell S-300i kunye neeseti ezimbini zezibetho: yam Revel Performa3 F206 kunye namanye ama-B & W CM10.
Xa ndibeka i-V90-DAC endaweni ye-Firestone Audio i-ILTW i-USB kuphela ye-DAC (engabonakali ukuba ikhona nanini kodwa endicinga ukuba iyindleko malunga ne-399 $), andinakutsho ukuba ndiphawule nayiphi na utshintsho kwi-sonic umlingiswa. Kodwa inkqubo yavakala kakuhle.
Ndazibona zonke iinkcukacha eziqhelekileyo ndizijonga xa kuhlolwe i-electronic audio. Ukubhinqa, izixhobo ezingenasiphelo zengqungquthela e-Holly Cole "Iingoma zeeTeyile" zikhutshwe ngaphantsi kwegumbi, zigijime kude ukuya kwesobunxele kwisithethi sasekhohlo kwaye kude ukuya kwesokudla kwisithethi esifanelekileyo. I-castanets e-Coryells '"Sentenza del Cuore: Allegro" ibonakala iphuma malunga neenyawo ezingama-25 emva kweentetho. Kanye njengoko konke okufunekayo.
Ngoko kwithuba elithile, ndandishiya i-V90-DAC kwinkqubo yam, ndonwabela nayiphi na into ndiyidlala kuyo, ukusuka kwi-CD ye- Guitar Guided Tour CD ukuya kwiPacific Rim ephuma kwiVudu ukuya kwii-TV ezikhethiweyo ezivela kwi-Amazon Instant Video.
I-Yep, i-V90-DAC ibonakale kakuhle, kodwa ingcono kangakanani ? Ukuze ndifumanise, ndibeka uvavanyo olungaboniyo, usebenzisa ukutshintshwa kwamatshini okuhlola okungaqhelekanga. Ndafanisa i-V90-DAC kwi-Firestone Audio ILTW kunye neNyanga ye-Simaudio ye-100D DAC. (ekuqaleni kwe-$ 649, ngoku i $ 399) ngoku. Ndafanisa i-V90-DAC kwisiphumo somfanekiso we-Panasonic Blu-ray. Zonke ezi mvavanyo zaziyimfama - ndiyazi kuphela ukuba ndidlala iDAC # 1, # 2 okanye # 3, kwaye emva koko yifumene ukuba yeyiphi. Wonke amanqanaba ahambelana no-0.1 dB usebenzisa i-control switches level controls.
Zonke ii-DACs ze-standalone zizwakala zilungileyo. Ngowokuqala kweengoma ezandiyidlalayo, andizange ndive umahluko oxabisekileyo xa usuka kwenye ukuya kwesinye. (Oku kusetyenziswa ii-16-bit / 44.1-kilohertz iifayili zikhishwe kwi-CD.) Kodwa emva kokunciphisa ambalwa, ndaqala ukuqaphela ukuba esinye sazo sazwakala siphundu phakathi kwe-midrange, kunye nomgangatho omncinane we-lispy okanye umgangatho onzima kumazwi. Omnye uzwakala efana kakhulu kodwa i-tad engaphelelangayo phakathi kweyesiqingatha. ezindlebeni zam, kwakubonakala kunika amazwi asemgangathweni onobuncwane, mhlawumbi unobuncwane benkcukacha kunye "nomoya."
Ngoko yeyiphi enye? Ijika i-V90-DAC ibetha i-100D ngokukhawuleza, ngelixa zombini ivakalisa ngcono kune-ILTW.
Xa kuthelekiswa ne-DAC ebhobho kwi-Panasonic Blu-ray isidlali - okuthi, kufuneka ndithi, kwakungalunganga nonke-i-V90-DAC inikezela iinkcukacha ezingakumbi, ngokukodwa kwi-midrange ehamba phambili nephezulu, eyenza i-Blu-ray I-DAC yomdlali inomsindo omncinane xa kuthelekiswa nangona ndasebenzisa ngakumbi izandi zeB & W ezivuthayo.
Ngaphambi kokuba ndiphephe, ndimele ndibonise ukuba ukungafani phakathi kwabaguquleli be-digital-to-analog ababenzi kakuhle abaqhelekanga, kodwa balapho, kwaye ukuba isandi sibaluleke kakhulu kuwe, ndicinga ukuba kukufanelekile ukutshala imali encinci yokuphucula ukusuka kwi-DAC eyakhelwe kwikhompyutheni yakho, iCD, iDVD okanye iBlu-ray isidlali kwi-DAC efanelekileyo, ephantsi i-DAC njengeV90-DAC.
Ndiya kuqaphela ukuba ukuba unayo nayiphi na ingcamango malunga nokusebenzisa i-V90-DAC kunye nomkeli we-A / V, ndingathanda ukuyibala. Nangona kukho abamukeli be-A / V abanesici esilungileyo se-analog, i-digize yonke impawu zomsindo we-analog eziza kuzo. Ukulungele ukuxhuma idivayisi yakho yomthombo ngqo kwi-receiver ngokusebenzisa uxhumano lwedijithali kunokuba ubuya kuguqula umqondiso kwi-analog kunye ne-V90-DAC kwaye uguqula kwakhona kwidijithali kwakhona ngaphakathi kwamukeli.
Imilinganiselo
Kwaye ndathatha ithuba lokuqhuba amanani ambalwa esheshayo kwi-V90-DAC, usebenzisa i-My Precision System System One Dual Domain analyzer. Nazi iziphumo. Ngaphandle kokuba kuphawulwe, yonke imilinganiselo ithathwe kwi-1 kHz.
Ukuphendula ngokuphindaphindiweyo: -0.05 dB @ 20 Hz, -0.30 dB @ 20 kHz
Isilinganiselo sesignali-kwingxolo: -112.8 dB engenakunzima
I-Crosstalk: -99.9 dB LR neRL
Isiphumo samaMax: 2.15 i-RMS
I-THD + ingxolo, imveliso enkulu: 0.008%
Akukho nanye kwezi ziphumo zintle nje ngokuba ziyi-specs, kodwa ngokukhawuleza ukucinga ukuba andizenzi ezininzi iimvavanyo zomsindo wangaphandle kwaye andinayo izixhobo zakutshanje kwaye zikhulu.
Gqibela Thatha
I-V90-DAC yinto enhle kakhulu ye-DAC yexabiso layo, indlela elula yokufumana isandi somculo se-stereo ebonakalayo esivela kumdlali we-Blu-ray umthengi, i-satellite receiver okanye i-cable box, okanye ikhompyutha ye-laptop.
Ukuba usebenzisa, tshela, umkhiqizo wekhonsom yekhompyutheni yakho ukuxhuma kwisistimu yakho ye stereo, okanye ukuba usebenzisa iDVD okanye iBlu-ray umdlalo wokudlala iiCD, ndingayincoma i-V90-DAC njengento elula, Iindleko eziphantsi, ezivakalayo zokuphucula inkqubo yakho.
