I-Ediscreation Firebird LPS Linear Power Supply Review – HiFiReport
Isidingo sekhwalithi ephezulu kagesi we-DC sikhule ngokushesha eminyakeni yamuva. Lokhu kubangelwa kakhulu ukusakaza-bukhoma kube indlela eyinhloko yokulalela yama-audiophiles. Kodwa-ke, amandla kagesi e-DC ahlanganisiwe kumadivayisi amaningi enethiwekhi yasekhaya, njengamarutha angenawaya, amaswishi enethiwekhi, amadivayisi e-NAS, amaseva omculo, nama-NUC mini-PC, avame ukuba yikhwalithi emaphakathi, ephazamisa ukusebenza komsindo. Ukuthuthukisa lezi zinsiza zikagesi kungathuthukisa kakhulu kokubili ikhwalithi yomsindo nesithombe, kwenze amandla angaphandle e-DC azo zonke izinhlobo abe indawo okugxilwe kuyo abathandi bomsindo.
Phakathi kwezinketho eziningi emakethe, i-Ediscreation Firebird LPS igqama njengembangi ephezulu.
I-CNC Machined Aluminium Chassis
I-Ediscreation okwamanje inikezela ngamandla kagesi alayini amathathu. Okubili yizinguqulo ezijwayelekile, ezihlukile nge-amperage ephumayo (ama-amps ayi-6 nama-amps ayi-10). Okwesithathu yi-Flagship Firebird LPS ebuyekeziwe lapha.
Kungakhathalekile izinga lazo, lezi zinto ezintathu ezisebenza ngomugqa zamandla zihlanganyela isici somklamo ojwayelekile: zinikeza i-voltage eyodwa kuphela ephumayo. Lokhu kuphambene namanye amabhrendi ngokuvamile ahlinzeka ngezinketho zamandla kagesi amabili noma amathathu ashintshekayo ukuze amukele amadivayisi ahlukene.
Kungani lokhu kukhetha kokuklama? Ingabe akulula kangako? Ngokwemvelo, kungenxa yekhwalithi yomsindo. Ukugxila emsebenzini owodwa kuvumela izinga eliphezulu lokucwengwa.
Ngakho-ke, i-Firebird LPS itholakala ngezinguqulo ezintathu: 5V/10A, 12V/10A, kanye ne-19V/6A. Iyunithi engiyithole ukuze ibuyekezwe inguqulo ye-12V, enezimbobo zokukhipha ezintathu kuphaneli engemuva futhi iza namakhebula kagesi e-OFC DC enziwe ngesandla, ngalinye lingamamitha angu-1.5 ubude. Ingakwazi kanyekanye amandla afinyelela kumadivayisi amathathu we-12V.
Naphezu kobukhulu bayo obuhlangene, i-Firebird LPS ikude nokuzithoba. I-chassis yayo yenziwe ngokunemba kusukela kubhulokhi eliqinile le-aluminium kusetshenziswa ubuchwepheshe be-CNC, okuholela ekuvaleni okuminyene ngokumangalisayo nokuqinile.
Ngaphakathi, i-chassis yakhelwe ngokucophelela ukuthi ifake kuphela i-toroidal transformer kanye nebhodi lesifunda samandla. Lezi zingxenye ezimbili zixhunywe isiteshi, zisebenzisa impahla ye-aluminium njengesithiyo esingokwemvelo sokuhlukanisa umsindo.
I-chassis ye-unibody futhi ihlinzeka ngokudambisa ukudlidliza okuhle kakhulu, ivikela ukujikeleza okuzwelayo ekuphazamisekeni kwemakrofoni—inzuzo ekabili.
Ngaphandle, i-Firebird LPS ifaka izinyawo eziyisilinda eziluhlaza okwesibhakabhaka ekhoneni ngalinye, ngayinye iphinde yenziwe ngomshini kusuka kumabhilidi e-aluminium aqinile.
Lezi zinyawo eziyisilinda azithinti ngokuqondile i-chassis kodwa zihlala ku-base plate futhi zivikelwe kuphaneli engezansi ngamakhoni.
Isilinda esiphezulu ngasinye sinomsele ohlisiwe, okuvumela ukupakishwa okuzinzile kwamayunithi amaningi e-Firebird LPS, okuhambisa kahle ukudlidliza kuya phansi futhi kuvimbele ukugxambukela—umklamo ohlakaniphe ngempela.
I-Discrete Components Circuitry
I-Firebird LPS ihlanganisa izici zokuklama eziyinkimbinkimbi.
Iziqhenya ngokuziqhenya ngomklamo wesifunda ohluke ngokuphelele, eschewing IC chips. Le ndlela kuthiwa iletha amandla aphezulu kuyilapho igcina amazinga omsindo aphansi kakhulu. Ngempela, umsindo olinganisiwe we-ripple uphansi ngokuphawulekayo, ku-0.02 mVrms nje.
I-toroidal transformer iyisiguquli esenziwe ngokwezifiso, esenziwe sodwa esisekelwe phansi, esithuthukisa ngokwengeziwe ukuhlukaniswa komsindo.
Ngaphakathi, isebenzisa ama-capacitor e-Mundorf e-premium anamandla amakhulu angu-30,000 uf, akhethelwe izici zawo ze-sonic.
I-AC input IEC inlet i-Furutech FI-03R, edume ngekhwalithi yayo nokuthembeka.
Iphaneli yangaphambili inemitha ecwengekile nehlangene, ebonisa amandla kagesi okukhiphayo futhi yengeza ukuthinta kokukhanga okubonakalayo. Imitha ikhanyiselwe emuva, futhi i-backlight ingacishwa nge-switch panel yangemuva.
Ngaphezu kwalokho, i-Firebird LPS ifakelwe ukujikeleza okubanzi kokuvikela, ukuvikela kumasekethe amafushane nokushisa ngokweqile, okuqinisekisa ukuphepha kokusebenza.
Izivivinyo zokulalela: Izimo ezimbili
Manje, ake siqhubekele emibonweni yokulalela.
Ukuze kube lula ukuhlola kwami, i-Top Sea Audiophile, umsabalalisi, unginikeze ngomusa izingxenye ezengeziwe ze-Ediscreation, okuhlanganisa nenguqulo ye-DC yeswishi yenethiwekhi ye-Silent Switch OCXO (inguqulo evamile inikwa amandla nge-AC), inguqulo ye-DC ye-Fiber Box II optical network isolator, kanye nenguqulo ye-Extreme ye-Fiber Box II. Lokhu kwangivumela ukuba ngenze ukuhlolwa kokulalela okuphelele.
Ukuhlola kwami kwahlukaniswe izingxenye ezimbili: Okokuqala, ngiqhathanise i-Firebird LPS kanye ne-Mean Well-medical-grade switching power supply lapho nginika amandla iswishi yenethiwekhi ye-DC Silent Switch OCXO, ukuze kuhlolwe umehluko. Okwesibili, ngiqhathanise inhlanganisela “ye-DC version Fiber Box II + Firebird LPS” ngokumelene nenguqulo ye-AC-powered Extreme ye-Fiber Box II, ukuze nginqume ukuthi i-Firebird LPS inikeza ukuthuthukiswa okwengeziwe.
Izivivinyo zokulalela zenziwa egumbini lami lokulalela lasekhaya, kusetshenziswa imishini elandelayo: i-Intel NUC egijima i-Roon Core, i-AURALiC Aries G1 yokusakaza yezokuthutha, i-Holo Audio Spring 3 DAC, i-Holo Audio Serene preamplifier, i-NuPrime Evolution One amplifier yamandla, kanye nezikhulisa-zwi ze-Aurum Cantus Grand Harmony.
Ukushintsha Kwenethiwekhi Ye-OCXO: Ukucaca kanye Nemvelo
Ngokusekelwe kokuhlangenwe nakho kwami kwangaphambilini uma ngiqhathanisa izinsiza zamandla ezilayini kanye nezishintshayo, amandla alayini ngokuvamile anikeza ukuthungwa kwe-sonic okuhlanzekile, ingemuva elithulile nelimnyama, kanye nokucabanga okugxile kakhulu nokunezinhlangothi ezintathu nokuminyana okungcono. Kodwa-ke, ukushintshanisa amandla ngezinye izikhathi kubonisa izinzuzo kalula nje, isisho esiguqukayo, nokuvuleka kwesiteji somsindo.
I-Firebird LPS ihlukile; idlula yonke into! Isibonelo, uma udlala i-mezzo-soprano u-Karen Cargill adlala ngayo umjikelezo wengoma ka-Berlioz ethi “Nuits d’été”, ikakhulukazi i-“Villanelle,” nokuhlelwa kwe-orchestra yegumbi lezintambo nama-woodwinds, inhlanganisela ye-Firebird LPS + Silent Switch OCXO yethule isiteji somsindo esihle kakhulu nesivuleke ngokwemvelo, esiqhathaniseka ne-Welling noma i-Mell switching.
Ngaphezu kwalokho, i-Firebird LPS ibonakala iphakamisa isiteji somsindo kancane, ithuthukisa umuzwa wokuphakama futhi yandisa ubukhulu obuqondile nobuvundlile, ithuthukisa umbono we-sonic uwonke.
Ngaphezu kwalokho, i-Firebird LPS ilole ukugxila kanye ne-contour yezithombe ze-sonic, izenze ziqine futhi zichazwe. Lokhu kuholele ekuhlukaniseni okuthuthukisiwe, okungivumele ukuthi ngibone kalula ubudlelwano phakathi kwezigaba ezahlukene zezinsimbi.
Ukwengeza, i-Firebird LPS ishelele ngokuphawulekayo imiphetho yokuthungwa kwe-sonic, njengokungathi ipholisha ubuhhadlahhadla noma imigqa emihle. Lokhu akugcinanga nje ngokuthuthukisa ikhwalithi yethoni kodwa futhi kwenza umculo uzizwe ushesha futhi unempilo.
Ngiphinde ngabona umuzwa okhulayo womoya kanye ne-ambience endaweni yokuqopha. Mhlawumbe yethule umuzwa ocashile womsebenzi wangemuva noma ukuphindaphinda okucebile, okufaka isandla ekuzizweleni okufana bukhoma.
Ukuthungwa kwezinsimbi ezihlukahlukene kuye kwacaca nakakhulu futhi kwacebile, okuhlanganisa ama-nuances acashile ekukhulumeni komculi, i-vocal timbre, ne-vibrato, konke okunikezwa ngokucacile okuthuthukisiwe.
Ukushintshela emuva ekushintsheni amandla kagesi we-Mean Well, isethulo somculo ngokushesha sabonakala singasacacisi, futhi umuzwa wobungqabavu wancipha. Isimo sezulu sisonke sadamba, sancipha kakhulu, futhi saba nokukhathala kancane. Nakuba umculo wawuhlala ujabulisa, injabulo yokulalela yancipha ngokuphawulekayo. Isiteji somsindo sibonakale sinenkontileka ngandlela thize, sigqamisa ukuvuleka nokwanda okuphakeme kweFirebird LPS. Kuyaphawuleka ngempela!
Amandla Omculo Athuthukisiwe
Ngokulandelayo, ngadlala umnyakazo wesibili we-Bruckner’s Symphony No. 9 kusukela ku-“Tutti!” ukuhlanganiswa kwe-orchestra. Ukuba sobala okukhethekile nokugxila kwenhlanganisela ye-Firebird LPS + Silent Switch OCXO kwangenza nganaka. Izintambo zokuvula ze-pizzicato bezithuthukise ukucwebezela kanye nokuthungwa okucwebezelayo, kuzwakala kufushane futhi kucacile. Izithombe zesigaba ngasinye sezinsimbi ziye zagxila kakhulu, zancipha kancane ngosayizi, kwathuthukisa ukuhlukana. Ukujula kwesiteji somsindo kwenyuke kakhulu, ngokwendlaleka okucace kakhudlwana phakathi kwezigaba zangaphambili nezangemuva, kanye nokunwetshwa okuvundlile okubanzi nokuma mpo, okunikeza umuzwa omkhulu wesikali ku-symphony. Ukukhanya okukhanyayo kwenza izinsimbi zethusi zizwakale zikhazimula ngokwengeziwe, futhi incazelo ye-timpani, umthelela, nokunwebeka kwaba ngcono. I-orchestra izwakale ihlangene kakhudlwana, inamandla ahlangene kakhudlwana, okuphumela esethulweni esinamandla.
Ngamafuphi, wonke umculo odlalwayo waba namandla, wamangalisa kakhulu, futhi wajabulisa kakhulu.
Ngikholwa ukuthi abathanda i-symphony ngokungangabazeki bazokujabulela lokhu! Kuthiwani ngomculo othandwayo? Ngidlale okuthi “Uma Uyahamba” ku-albhamu ka-Jonathan Lee ethi “Rational & Sensual Works Concert”, equkethe izigubhu, amabhesi kagesi, upiyano, amakhibhodi, nezinye izinsimbi. Nge-Firebird LPS, imisindo yesigubhu ithole ukugxila ngokuphawulekayo, enezinhlaka ezicacile, okwenza ukubekwa kwezigubhu ezahlukene kuhluke kakhulu. Imisindo yesigubhu nayo ibe nomthelela omkhulu futhi amandla ahlabayo agqama kakhulu.
Ngokufanayo, ukulalela i-“Li Xianglan” evela ku-albhamu ka-Sandy Lam yesiCantonese ethi “Walk With Me,” efaka isiginci sakudala sezintambo zenayiloni kanye ne-cello, zombili izinsimbi ezithatha ibanga elimaphakathi nefrikhwensi futhi ezingakhanyi ngokwemvelo nge-timbre. Kodwa-ke, nge-Firebird LPS, ukuthungwa kwethoni yesiginci kube msulwa futhi kuhlanzeke ngaphakathi kokufudumala kwaso. Ukuchazwa kwenothi kwacaca futhi kwagqama, kwangathi amandla okucosha iminwe nokuhluthula ayaqina.
Ngaphezu kwalokho, amazwi kaSandy Lam athole ukubonakala okuthuthukisiwe, ukucaca okuthuthukisiwe, kanye nekhwalithi elula. Imisindo yokuphefumula, ukuhluka kwezwi, kanye nolwazi lwendawo kwethulwe ngokucacile, ngokujula okukhulu, okwenza umqondo wendawo ukhombe kakhulu futhi uchazwe.
Ukuchazwa Kwezithombe Okuthuthukisiwe Nesiteji Somsindo
Ukusebenzisana phakathi kwe-Firebird LPS kanye nenguqulo yenethiwekhi ye-DC Thulisa Shintsha i-OCXO kuyamangalisa ngempela. Kodwa ingcono kangakanani i-Firebird LPS uma ibhangqwe ne-DC version ye-Fiber Box II optical network isolator uma iqhathaniswa nenguqulo ye-Extreme Fiber Box II, esivele inomugqa ophezulu wamandla olayini owakhelwe ngaphakathi? Ake siphenye.
Ukuze uthole imininingwane enemininingwane kanye nokubuyekezwa kwe-Fiber Box II optical network isolator, abafundi abanentshisekelo bangabheka esihlokweni esithi “Ediscreation Fiber Box II Optical Network Isolator.”
Ngimise i-Fiber Box II phakathi kweswishi yenethiwekhi kanye nezokuthutha ezisakazwayo ze-AURALiC Aries G1, ngisebenzisa ukuqhathanisa kwe-A/B ukuze ngihlole umehluko phakathi kwenguqulo ye-DC kanye ne-Extreme.
Idlala ingoma kaJennifer Warnes ethi “In the Still Of The Night,” inguqulo ye-Extreme izwakale ishisa kancane, nesiteji somsindo esibekwe phambili kancane futhi singashoni kakhulu ekujuleni.
Ukukhanya okuphelele komculo bekungaphansi kwenguqulo ye-DC, kodwa ngokungananazi, bekusazwakala kukuhle kakhulu.
Ukushintshela enguqulweni ye-DC, isithombe sephimbo saba namandla kakhulu, futhi i-bass plucking yayinencazelo yenothi egqame kakhudlwana, njengokungathi izintambo ziqinisiwe, okwenza umsindo usheshe kakhulu. Esanduleleni sezintambo, ukubekwa kwezingxenye ezingaphambili, ezimaphakathi, nezangemuva kuye kwahluka kakhulu, kwaba nokuma okucacile nokuhlukana. Ngesikhathi esifanayo, ubukhulu besiteji somsindo obuthathu, incazelo yendawo, nokujula konke kunikezwe ngokucacile okuthuthukisiwe. Ukuthungwa kwethoni kuye kwacaca kakhudlwana, okwenza umculo uzizwe ulula futhi nomoya ubonakale usha futhi uhlanzekile, okuholela ekulaleleni okuqabulayo kakhudlwana.
Ukushintshela emuva kunguqulo ye-Extreme, uma kuqhathaniswa, ukuhlukaniswa kwezingqimba zangaphambili, ezimaphakathi, nezangemuva zokuhambisana bekuchazwe kancane, futhi ithoni ye-bass ibifudumala kancane futhi inothi iveza ukucijile kancane kancane. Nokho, lezi kwakuwumehluko obonakalayo kuphela ekuqhathaniseni okuqondile. Ngaphandle kokuqhathanisa, zombili izinguqulo zinhle kakhulu!
