Ingabe kuhlale kuthetheleleka ukuthi imikhiqizo evela kwamanye amazwe ibize amanani aphezulu, kuyilapho izinhlobo zomsindo wasekhaya ezithengisa ngamanani afanayo zibhekana nokungabaza? Lo mbono osunesikhathi eside, obonakala wamukelwe, yinto uMnu. Wen, oqhuba i-Diva Audio, angavumelani nayo kakhulu. Ngaphandle kwalokho, ubengeke asungule uhlobo lwe-Diva Audio, oluzinikele ekukhiqizeni kuphela imishini yomsindo yezinga eliphezulu.
Ngemva kokubuyekeza ikhebula lenethiwekhi yeVenus, ngase ngiwazi amakhono e-Diva Audio. Kulokhu, ukuhlola ukushintshwa kwenethiwekhi ye-EX-7 kuphinde kwangimangaza. “Kuphawuleka ngempela!” Ngingasho ngokuqiniseka ukuthi i-EX-7 iphakathi kwamaswishi enethiwekhi ye-audiophile-grade atholakalayo namuhla, ekwazi ukuzibamba ngokumelene nanoma yimuphi imbangi.
Ifilosofi yokuklama
Yini eyivumelayo ukuthi ifinyelele ukusebenza okuhamba phambili emakethe? Impendulo ilele kwezobuchwepheshe kanye nokuzinikela okungantengantengi ekwenzeni okuhle.
I-EX-7 ingumzamo wokusebenzisana phakathi kwePurisa neMagcom Corporation. I-Magcom igxile ezingxenyeni zokuxhumana kazibuthe, ingxenye ebalulekile yenethiwekhi nezimboni zokuxhumana. Banobuchwepheshe obubanzi namalungelo obunikazi, okwenza ukwakhiwa kweswishi yenethiwekhi kube umsebenzi olula kubo. Nokho, ukushintshwa kwenethiwekhi ye-audiophile-grade bekuyindawo engashiwongo.
Kuze kube manje, iMagcom ilahle ubuhlakani obujwayelekile mayelana nokudluliswa kwedatha yenethiwekhi futhi yaqala ngesileti esihlanzekile. Idizayini yabo igxile kuphela enjongweni eyodwa: ukuzuza ikhwalithi yomsindo ekhetheke kakhulu. Ngaphezulu kweminyaka emibili yocwaningo nentuthuko, bazibandakanya ngokungakhathali ezivivinyweni zokulalela eziphindaphindiwe, ukuqhathanisa, nokuguqulwa. Le nqubo ephindaphindwayo yokucwenga igcine iholele ekwakhiweni kwe-EX-7.
I-Core Technologies
I-EX-7 inkulu ngokomzimba kunanoma iyiphi enye i-audiophile-grade network switch emakethe njengamanje. Kungani kunosayizi omkhulu kangaka? Ngokungangabazeki, kungenxa yomsindo ophakeme.
Ukuvula i-EX-7 chassis kuveza ukwakheka kwesekethe yangaphakathi ehlelwe kahle, ngokuyinhloko ihlukaniswe yaba izigaba ezintathu: i-toroidal transformer enikeza amandla amakhulu, indawo ebiyelwe yensimbi evaliwe enophawu lwe-δiva (okungenzeka ukucubungula amandla), kanye nebhodi lesekhethi yokushintsha inethiwekhi ngokwayo.
Phakathi kwalezi zingxenye, indawo ebiyelwe ngensimbi emhlophe ngokungangabazeki iwubuchwepheshe obubaluleke kakhulu, obuhlala obuningi bobuchwepheshe obubalulekile. Ngenxa yamalungelo obunikazi e-Magcom, ihlala ivaliwe, ifihla ukusebenza kwayo kwangaphakathi. Ngaphezu kwalokho, indawo ebiyelwe yensimbi inikeza isivikelo esisebenzayo, ivimbela ukuphazamiseka emsindweni kanye nokuvuza kwe-transformer magnetic.
Isifunda sokushintsha sihlanganisa izici ezimbalwa ezibalulekile zokuklama. Okokuqala, wonke amachweba wenethiwekhi ye-RJ45 ayisishiyagalombili ayimikhiqizo kaMagcom. Lawa machweba ahlanganisa izingxenye kazibuthe (iziguquli zokuzihlukanisa), ezibalulekile ekuhlukaniseni umsindo wenethiwekhi.
Okwesibili, ukwakheka kwesekethe kusuka ku-chip yenethiwekhi kuya emachwebeni ayisishiyagalombili enethiwekhi akuhlelwanga kahle kuphela kodwa futhi kuhambisana ngokuphelele. Lo mklamo wamabomu awukona nje ukukhanga ubuhle; kufeza injongo engokoqobo ngokufaka isandla ekunembeni kokudluliswa kwesignali yephakethe.
Ngaphezu kwalokho, i-EX-7 ihlanganisa i-TCXO crystal oscillator enembayo ephezulu njengomthombo wayo wewashi. Le ngxenye inciphisa ngempumelelo amaphutha okudlulisela isignali.
Ukuqhubekela ku-chassis ye-EX-7, ngenkathi ingeyona ingxenye eqondile yesekethe, i-chassis eklanywe kahle ingathuthukisa kakhulu ikhwalithi yomsindo. I-EX-7 chassis yakhiwe ngamapuleti aminyene e-aluminium, avikelwe kuzo zonke izinhlangothi eziyisithupha. Iphaneli yangaphambili ene-beveled yenziwe ngomshini kusuka kubhulokhi eyodwa ye-aluminium kusetshenziswa ukusika ukunemba kwe-CNC. Uma sesihlanganisiwe, isakhiwo sisonke siqine ngendlela ehlukile futhi sisinda ngokuphawulekayo, okubonisa ukucindezelwa okuhle kakhulu kwe-chassis resonance.
Inqubo Yokushuna Umsindo
Kuyo yonke intuthuko ye-EX-7, ukuhlolwa okubanzi kokulalela bekubalulekile ukuze kuqinisekiswe ukusebenza kwayo kwe-sonic. UMnu. Chang Yun-Jieh, umnikazi we-HiFiReport, unikeze usizo olubalulekile kule nqubo.
UMnu. Chang wachaza ukuthi indima yakhe yayingaphezu kokulalela nje. Ulethe amaswishi amaningi enethiwekhi avamile atholakalayo njengamanje emakethe futhi wenza ukuqhathanisa kwe-A/B ukuze aqonde imikhawulo yokusebenza kwe-EX-7 futhi anikeze impendulo yokuthuthukiswa.
Ngezibuyekezo eziningi neziqhathaniso zokulalela eziphindaphindiwe, idizayini yaqedwa kuphela lapho uMnu. Chang ebona i-EX-7 ikwazi ukumelana nanoma iyiphi inselele, ivula indlela yokukhululwa kwayo emakethe ngokusemthethweni.
Kuyini ukusebenza kwangempela kwe-EX-7? Ngibe nethuba lokuhlola i-prototype egunjini lokulalela le-HiFiReport ngesikhathi sokuthuthuka. Nalapho, ngasibona isisekelo sayo esiyingqayizivele namandla amakhulu. Manje, ngemva kokuthola iyunithi ephothuliwe, ekhiqizwe ngobuningi, ngayibuyisela endaweni yami yokulalela ekhaya engiyijwayele ukuze ihlolwe ngokugcwele.
Izingxenye zomthombo ezisetshenziswe kunhlolokhono kwakuyizithuthi zokusakaza ze-AURALiC Aries G1, ezixhunywe nge-USB ku-Holo Audio Spring 3 DAC. Umculo uthathwe kukhompyutha encane ye-Intel NUC esebenzisa uhlelo lwe-Roon ROCK.
Ngixhume i-Aries G1, Intel NUC, nerutha engenantambo ku-EX-7. Ukuze uthole isixhumanisi esibalulekile phakathi kwe-Aries G1 ne-EX-7, ngisebenzise intambo yenethiwekhi ye-Diva Audio ye-Venus.
Iyunithi yereferensi yokuqhathanisa bekuyi-Qnap QSW-308S. Lokhu kushintsha kwenethiwekhi kufaka phakathi amachweba angu-3 we-10GbE SFP+ fiber kanye namachweba angu-8 we-1GbE Ethernet, ayibeka njengenketho yokusebenza okuphezulu esigabeni sabathengi.
Ukuthuthukiswa Okubalulekile kwe-Sonic
Ngaqala ngokulalela uTrevor Pinnock eqhuba uhlelo lwe-English Concert of Bach’s Violin Concertos, ngikhetha umnyakazo wesibili, “Adagio,” ekhonsathini enkulu ye-E. Ngemva kokuqhathanisa okumbalwa nje, ukuthuthukiswa “okumenyezelwe” okunikezwa yi-EX-7 kwabonakala ngokushesha.
Igama elithi “liphinyiselwe” lapha libhekisela ebukhulwini bentuthuko, hhayi ukwanda komfutho womculo.
I-EX-7 ayenzi umsindo uqine noma ube nolaka. Kunalokho, kuwenza ube bukhoma, ube ngokwemvelo, futhi ube ngokoqobo, ugcwalise umculo ngamandla amakhulu.
Ngokuhlangenwe nakho kwami, i-EX-7 iletha ukuthuthukiswa kwe-sonic okubaluleke kakhulu uma kuqhathaniswa nanoma iyiphi enye inkinobho yenethiwekhi ye-audiophile-grade engike ngayisebenzisa kuze kube manje.
Nge-EX-7, ama-nuances wemigqa yensimbi yeyunithi yezinhlamvu kanye nezigaba eziguqukayo kunikezwa ngokucophelela. Ama-Micro-dynamics ahluka kakhulu, futhi umculo ubonakala uphefumula. Ngokuphawulekayo, ukuqoshwa okufanayo, uma kudlalwa nge-EX-7, kuzwakala kuhamba kancane, kunomuzwa ophakeme wokugeleza.
Ngaphezu kwalokho, ukuthuthukiswa kubonakala ngokusobala ezicini ezifana ne-ambience, i-spatial imaging, ukujula kwesiteji somsindo nobubanzi, ukubekwa kwezinsimbi, nokuhlukaniswa.
Amafrikhwensi aphezulu ezintambo akhanya ngokuphawulekayo, anwebeka kalula ngomoya omuhle kakhulu. I-bass iyanwebeka kakhulu, ithuthukisa isigqi somculo. Iziphetho eziphakeme neziphansi ze-frequency spectrum zibonakala zanda, zidala umuzwa omkhulu wokuvuleleka. Amafrikhwensi aphansi athatha indawo yawo efanele ephansi, futhi amafrikhwensi aphezulu akhuphuka ebangeni lawo eliphezulu, okuholela ekwakhekeni kwe-sonic echazwe kahle futhi ehlelekile.
I-Timbrally, umsindo uba ohlanzekile, osobala kakhulu, futhi uhlanzeke, njengomthombo oqabulayo, umthinta ngokujulile olalele.
Ngokuphambene, inkomba yenethiwekhi ye-Qnap switch yenza umculo uzwakale unamandla uma kuqhathaniswa ngoba iziqephu ezithule azinayo incazelo, futhi i-timbre iyoma kakhulu, ayinakho ukunotha kombhalo. Izinga le-ethereal lezintambo liyancipha, futhi ukugqama kuyancipha. Imigqa yezinsimbi ihunyushwa ngendlela eqondile, okwenza umsindo uzizwe ungaphelele, ikakhulukazi intula imininingwane ecashile ngamavolumu aphansi.
Nakuba kungajabulisi, kuzwakala “kubi” uma kuqhathaniswa.
Ukwengeza, ibhesi yeyunithi yereferensi iyasinda, inamakhonco angachazwanga kangako, imigqa, nezendlalelo, ayinakho ukushesha.
Phakathi nemigqa yezintambo ezinomsindo kumaza aphezulu, umsindo ungaba nzima, futhi isiteji somsindo sivame ukuwa sibheke maphakathi, sintule ukuvuleka.
Lo mehluko ubonakala kalula, kakhulu kakhulu kunokwehluka okucashile engihlangabezane nakho ekubuyekezweni koshintsho lwenethiwekhi edlule uma kuqhathaniswa neyunithi yesithenjwa efanayo.
Ukuthuthukiswa Kwezinga Lesistimu
Okulandelayo, ngadlala irekhodi elidumile le-audiophile elithi “Antiphone Blues,” equkethe i-saxophone ne-pipe organ, eyaziwa ngekhwalithi yayo yokuqopha eyingqayizivele.
Iculo lesibili elithi, “Akekho Owazi Inkinga Engiyibonile,” iqala ngokuthi i-ogani yepayipi idlale ngevolumu ephansi kakhulu, ephelezelwa izintambo eziphakeme kanye nomugqa webhesi ocashile, onganyakazi. Ngeyunithi yereferensi, imigqa yefrikhwensi ephezulu nephansi izwakale ithi ukugqagqana, ingenakho ukuhlukana okucacile kukho kokubili ukuma nokujula. Ifomu lomugqa we-bass nalo belingacacile, okuholele ekubonakaleni kobukhulu besikali.
Ingemuva elimnyama lalingenangqondo, futhi i-timbre yayibonisa izinga elithile lodaka.
Ukushintshela ku-EX-7, imigqa ye-high-frequency yaba intekenteke futhi icacile, imiswe ngokuqhubekayo emuva ku-soundstage. I-bass line idlulisele umuzwa wokudlidliza komoya ngaphakathi kwamapayipi otho, onesimo esihlukile, kunokuba usabalale ngokusabalale. Ngaphezu kwalokho, ukuthungwa kwakuhlanzekile futhi kwakhiwe.
Ukuphindaphinda kwakucace ngendlela engavamile futhi kwanwetshwa, kwambuleka ngokungapheli, ngaleyo ndlela kuveza ngokusobala ububanzi nokujula kwesikhala se-acoustic.
Lapho i-saxophone ingena, kwavela isakhiwo esicacile esicacile: i-saxophone phezulu, okhiye abaphezulu phakathi nendawo, kanye nokhiye ophansi phansi, okwenza isethulo esihlelekile nesigqinsi.
I-timbre yayihlanzekile, ihlanzekile, futhi ikhanya, icwebezela ngokuqabulayo kodwa inothile efanele. Imigqa yezinsimbi beziqinile, nokuminyana okuhle kakhulu.
Isistimu yomsindo efanayo, ngokushintsha inkinobho yenethiwekhi, iveze amazinga amabili ahlukene okusebenza. Umehluko wenani cishe unamandla amakhulu! I-EX-7 iyamangalisa ngempela!
