I-D- $ 300 ye-DAC eyenza konke? Cishe.
Kubonakala sengathi yonke imibhangqwana yeminyaka, abaguquli be-digital-to-analog bahamba nge-revolution. Eminyakeni embalwa edlule bonke bangeze i-USB. Ngonyaka we- Rocky Mountain Audio Fest , sabona ama-DAC amaningi kakhulu - ngisho nangaphansi kwezingu-400 400 - enezela ukudlala okuphezulu kokuxazulula okuphezulu kwe-DSD. Yini elandelayo? Mhlawumbe i-HDMI . Njengoba ushintsho oluningi luqhubeka, ungenza icala elihle ngokuthenga nje into enhle futhi engabizi kunokuba usebenzise imali eningi ukuxosha zonke izici ezintsha. Yilapho i-V90-DAC ingena khona.
I-Musical Fidelity yakha i-$ 299 i-V90-DAC njengengxenye ye-V90 line, izingxenye eziphansi zezindleko eziphansi, ezingekho frills ezenzelwe ama-audiophiles azimisele ukuchitha okunye okunye okuhle kodwa azifuni ukuchitha yonke idola elidlule for state-of-the-art.
Iphaneli elingemuva linemigomo emine yedijithali: i-USB engenasisekelo, i-coaxial RCA, nama-Toslink amabili optical. Imiphumela ibekwe kuma-jacks we-RCA stereo. Iphaneli langaphambili linamandla nje nokushintsha kokufaka.
Ngakho yini elahlekile? Izinto ezimbili. Enye, ukufaka kwe-USB kwamukela izibonakaliso zedijithali kuze kube nesisombululo se-24-bit / 96-kilohertz; ngeke lamukele umsindo we-192-kilohertz high-res, kodwa eziningi ze-DAC kulolu hlu lwamanani ngeke. Ungenza u-24/192 ngokusebenzisa okokufaka kwe-coax, kodwa uma udonsa lawo mafayili kukhompyutha, uzodinga i-adapter ye-USB-to-coax. I-V90-DAC yenza konke okushiwo yi-sample kuze kube ngu-24/192. Futhi uma unamafayela angu-24/192 kukhompyutheni yakho, izoqhubeka iwudlala, kodwa ikhompyutha izobahlehlisa kuze kube ngu-24/96. Futhi i-V90-DAC ayinayo i-headphone jack, okuyisici ongase ungayifuni noma ongayifuni, kodwa itholakala kuma-DAC amaningi kulezi zinsuku.

Ukusetha / Ergonomics
Akukho lutho olufanele ukuphawula lapha. Xhuma amandla okufaka udonga wendiza, hlanganisa zonke izinto zakho zedijithali, xhuma i-V90-DAC ku-preamp noma umamukeli wakho, futhi ube nayo. Amakhomphyutha e-HP, i-IBM ne-Toshiba engayisebenzisa nge-V90-DAC ayawubona ngokushesha.
Ngithande ukulula kokushintsha komshini wokukhetha esikhundleni se-inkinobho eziningi ze-DAC ezisetshenziselwa ukupheqa phakathi kokufakwayo. Kodwa ngifisa ukuthi i-V90-DAC ibe ne-front input ye-USB eyenza kube lula ukuxhuma i-laptop yami.
Ukusebenza
Kwaphela amasonto ambalwa, ngasebenzisa i-V90-DAC ngokwayo njengomthombo omkhulu wedijithali ohlelweni lwami, ngiwuxhuma kumdlali wami we-Panasonic Blu-ray kanye ne-laptop ye-Toshiba engiyisebenzisa kakhulu umculo wami wokudlala. Ngasebenzisa i-amp Krell S-300i ehlanganisiwe namaqoqo amabili ezikhulumi: iRevel Performa3 F206s yami kanye namanye ama-B & W CM10.
Uma ngifaka i-V90-DAC esikhundleni se-Firestone Audio ILTW USB-kuphela i-DAC (engabonakali ukuthi ayitholakali nokho kodwa engicabanga ukuthi ibiza cishe ngama-$ 399), angikwazi ukusho ukuthi ngiqaphele ushintsho oluthile lwe-sonic umlingisi. Kodwa uhlelo luzwakala kahle kakhulu.
Ngiqaphele yonke imininingwane ejwayelekile evamile engiyifunayo lapho kuhlolwa khona ama-audio alalelwayo. Izinsimbi zokugubha, ezingenakuphumula ezingxenyeni zikaHolly Cole's "Train Song" zazingena egumbini, zigijima kude ngakwesobunxele sesikhulumi sesokunxele nakude kwesokudla kwesipikha esifanele. Ama-castanet ku-The Coryells '"Sentenza del Cuore: Allegro" kubonakala sengathi avela ku-25m ngemuva kwezikhulumi. Njengoba nje konke kufanele.
Ngakho-ke, okwesikhashana, ngavele ngishiya i-V90-DAC ohlelweni lwami, ngijabulele noma yini engidlala ngayo, kusukela ku-CD ye- Guitar Tour Guided Tour kuya e- Pacific Rim ehamba esuka ku-Vudu ukuya emibonweni ye-TV engahleliwe esuka ku-Amazon Instant Video.
I-Yep, i-V90-DAC ibonakale kahle, kodwa kuhle kangakanani ? Ukuze ngithole, ngimisa ukuhlolwa okuyimpumputhe, ngisebenzisa ukushintsha ukuhlolwa kwami okuyimpumputhe. Ngayifanisa i-V90-DAC ku-Firestone Audio ILTW no-Simaudio's Moon 100D DAC. (ekuqaleni kuka-$ 649, manje ngu-$ 399). Ngiphinde ngiqhathanise i-V90-DAC kumkhiqizo we-analog we-Panasonic Blu-ray player. Zonke lezi zivivinyo zaziyimpumputhe - ngiyazi kuphela ukuthi ngidlala i-DAC # 1, # 2 noma # 3, futhi kamuva nje ngacabanga ukuthi yiyiphi. Wonke amazinga afanelwe ku-0.1 dB usebenzisa ukulawula kwezinga lokushintshwa.
Wonke ama-DAC ajwayelekile azwakala kahle. Ukuze ngidlale izingoma zombili zokuqala, angizange ngizwe umehluko ozwakalayo uma usuka komunye kuya kwesinye. (Lokhu kwakusebenzisa amafayela angu-16-bit / 44.1-kilohertz avela ku-CD.) Kodwa emva kokusikeka okuncane, ngaqala ukubona ukuthi omunye wabo uzwakala elula phakathi ne-midrange, engenamakhono angaphansi kwe-lispy noma ahlukumezayo ngamazwi. Omunye uzwakala ofana kakhulu kodwa u-tad kancane ubushelelezi emaphakathi. ezindlebeni zami, kwakubonakala kunika amazwi ngekhwalithi engcolile, okungeyona imininingwane eyanele futhi "emoyeni."
Ngakho yiyiphi enye? Yenza i-V90-DAC ibethe i-100D kancane kancane, kuyilapho kokubili kubo bezwakala kangcono kune-ILTW.
Uma kuqhathaniswa ne-DAC ebhodini ku-Panasonic Blu-ray isidlali - okuthi, ngithi, kwakungalungile nhlobo - i-V90-DAC inikeze imininingwane eminingi, ikakhulukazi emgodini we-treble nephezulu, okwenza i-Blu-ray I-DAC yomdlali inomsindo omncane uma kuqhathaniswa ngisho nalapho ngisebenzisa izisindo zeB & W ezithandayo ezithandayo.
Ngaphambi kokuba ngiphethe, kufanele ngibonise ukuthi umehluko phakathi kwabaguquli be-digital-to-analog eyenziwe kahle kaningi kakhulu, kodwa kukhona lapho, futhi uma umsindo ubaluleke kakhulu kuwe, ngicabanga ukuthi kufanelekile ukutshala imali encane ukuze uthuthukise kusuka ku-DAC eyakhelwe kukhompyutha yakho, i-CD, i-DVD noma i-Blu-ray isidlali ku-DAC enhle, ephansi njenge-V90-DAC.
Ngiphinde ngiqaphele ukuthi uma unemiqondo mayelana nokusebenzisa i-V90-DAC ne-receiver A / V, ngingathanda ukuyikhohlwa. Nakuba kunamamukeli we-A / V anesici sangempela se-analog, i-digitize zonke izibonakaliso zomsindo we-analog eziza kuzo. Kungcono ukuxhuma idivayisi yakho yomthombo ngokuqondile kumamukeli ngokusebenzisa uxhumano lwedijithali kunokuba ungaguqula isignali ku-analog nge-V90-DAC bese uyibuyisela kudijithali futhi ngaphakathi kwamukeli.
Izinyathelo
Ngiphinde ngithatha ithuba lokusebenzisa amalinganiso ambalwa we-lab okusheshayo ku-V90-DAC, ngisebenzisa i-Audio Precision System One One Dual Domain analyzer. Nazi imiphumela. Ngaphandle kokuphawula, zonke izilinganiso zithathwe ku-1 kHz.
Impendulo yephindaphindiwe: -0.05 dB @ 20 Hz, -0.30 dB @ 20 kHz
Isilinganiselo sokubonisa umsindo: -112.8 dB engenamandla
I-Crosstalk: -99.9 dB LR no-RL
Ukukhipha okuphezulu: 2.15 ama-volts e-RMS
I-THD + umsindo, okukhipha okuphezulu: 0.008%
Ayikho yalezi ziphumo ezihle kakhulu njengama-specs omkhiqizi, kodwa ngokuzenzekelayo ngokucabangela ukuthi angenzanga eziningi zokwenziwa komsindo wangaphandle futhi anginayo imishini yakamuva futhi enkulu kunazo zonke.
Thatha okokugcina
I-V90-DAC i-DAC enhle kakhulu ezwakalayo ngentengo yayo, indlela enhle yokuthola umsindo wangempela we-audiophile-quality stereo umsindo kusuka kumdlali we-Blu-ray we-mass-market, isamukeli se-satellite noma i-cable box, noma ikhompyutha ye-laptop.
Uma usebenzisa, tshela, ukukhishwa kwesikrini sekhompyutheni yakho ukuxhuma kwisistimu yakho ye-stereo, noma uma usebenzisa i-DVD noma i-Blu-ray isidlali sokudlala ama-CD, ngingancoma i-V90-DAC njengento elula, indlela ephansi, ezwakala kakhulu yokuthuthukisa uhlelo lwakho.
