Mbere gato yo gushyiramo RAAL HSA-1b, nacurangaga LP idasanzwe ya EMI yitwa Renaissance Suite, irimo umuziki wo muri filime ya Joël Santoni yo mu 1974 yitwa La Course en Tête (HQS 1415). Iyi filime ivuga ku mwuga w'icyamamare mu magare cy'Umubiligi Eddie Merkex mu buryo butangaje kandi butangaje bw'ubuhanzi. Ikintu kidasanzwe ni uko aya manota yanditswe kandi agategurwa n'inzobere mu muziki wo mu ntangiriro z'Umwongereza David Munro, kandi yakinwe n'Ishyirahamwe ry'Abaririmbyi b'Imbere rya Muzika rya London, ryuzuyemo imbaraga. Tekereza filime ya siporo irimo amajwi yo gucuranga umwirongi, tromba marina ("violon ya nun"), na rauschpfeiffen baherekejwe n'abantu bambaye amakabutura magufi n'amashati meza bagenda ku magare magufi ku misozi y'i Burayi.
Ikoresheje 300B Elekit TU-8600 mu gutwara LS3/5as, Renaissance Suite yerekana amajwi y'ibiti n'imirya y'inda, bituma umuziki wa Munrow wo hambere wumva ari uw'ukuri, wo mu gihe cya kera kandi udasanzwe. Ifite imiterere myiza kandi ishimishije, ariko ijwi ryayo ni ryiza.
Ubwo nahuzaga Zahabu Badges na amplifier ya RAAL HSA-1b, ijwi ryarushijeho gukomera no kumvikana neza. Hamwe na HSA-1b, urujya n'uruza rw'umuziki ni byo byiganje mu bwenge bwanjye. Umuziki urahinduka cyane. Iyo umuziki urushijeho kuba mwinshi, ibihangano bya David Munrow birushaho kugira icyo bivuze.
Iyo nhinduye igikoresho cyo mu bwoko bwa Falcons gikoresha ikoranabuhanga rya SR1a rifunguye cyane? Kuva ku ndangururamajwi kugeza ku ndangururamajwi? Nabonye uburyo bwo kureba amajwi neza kandi yibanda ku majwi.
Transducer ya RAAL ifite umutwe ushyirwa ku gisenge cy'icyuma ni umwihariko ku isoko rya ecouteur. Irakomeye kandi ihendutse ($3,500). Kaseti ya dipole ya SR1a ishyirwa mu gisenge cy'icyuma kitagira umugese kure y'umutwe. Ni uduce nyatwo, kandi amplifiers zigaragaza zifite impedance y'umutwaro wa short-circuit: 0.2 ohms, harimo n'insinga. Igitabo cy'amabwiriza gisaba ikoreshwa ry'imbaraga za amplifier za 100W (incamake ya 1). Hamwe n'umutobe uhagije wa amplifier, SR1a itanga urwego rw'amajwi rwinshi, rudafite ibara, kandi rudahindagurika cyane (ndizera ko) rurenze Stax SR-009S static ikomeye cyane hamwe n'ikintu cyanjye nkunda cya JPS Labs Abyss AB-1266 Phi TC na HiFiMan Susvara planar magnetic element.
Ecouteur za SR1a zikenera imbaraga nyinshi cyane zo gutera inkunga amajwi, bityo bisa nkaho bihuje n'ubwenge ko RAAL-requisite ikora amplifier ishobora gutwara ecouteur zabo cyangwa indangururamajwi zanjye hamwe n'akantu gato k'inyuma.
Amplifier nshya ya HSA-1b ya HSA-1b RAAL (inyuguti zo hepfo ya 2) ni yo amplifier ya mbere ya solid-state na headphone nagerageje. Igihe nayihuzaga na speaker ya Stenheim Alumine Three ihagaze hasi maze nkumva ko ishobora gutwara indangururamajwi ebyiri zifite agaciro k'amadolari ya Amerika 32,900, namenye ko ari ubwoko butandukanye bw'indangururamajwi ugereranyije na amplifier ya Linear Tube Audio ya 10Wpc (8 ohm) Z10e/ Headphone ya Linear Tube, nayisuzumye muri Gramophone Dreams #36 cyangwa Ampsandsound ya 8Wpc (8 ohm) Bigger Ben, kandi nayisobanuye muri Gramophone Dreams #47.
HSA-1b ya RAAL ni amplifier ntoya itukura ifite imiterere y’ibiro 11.7, ifite ingano iringaniye, uburebure bwa santimetero 3.5 x ubugari bwa santimetero 8.6 x ubujyakuzimu bwa santimetero 12.6. Ikoresha transistors ebyiri za bipolar junction (BJT) kuri buri muyoboro. Amaboliti abiri ahujwe na radiator imwe ya aluminiyumu ifite uburebure bwa santimetero 8.5 × 2.
Ubwiza bw'inganda buri hejuru cyane ku buryo muri urwo rwego, HSA-1b isa n'aho yujuje ibisabwa bya gisirikare. Mu miterere yayo, urwego rwo hejuru rwo kuyitunganya no kuyirangiza bifite uburemere bw'imbaraga z'inganda ndetse n'ubwiza bw'imitako yo mu rugo.
Uretse (kandi iruhande) rw'aho umuriro wa IEC ushyirwa, igice cy'inyuma cya HSA-1b gifite uburyo bubiri bwo kwinjira: igice kimwe (RCA) n'igice cyo kuringaniza (XLR). Hariho kandi amapine abiri ya banana plug jacks yo guhuza indangururamajwi za stereo. Munsi y'ikiranguruzi, handitseho "Serbian SAEQ yakozwe kandi igakorwa hakurikijwe ibisabwa na RAAL".
Nk’uko Aleksandar Radisavljevic, umuyobozi w’ikigo cyose cya RAAL-requisite abivuga, “SAEQ isobanura ibikoresho by’amajwi byo muri Seribiya. Ni ikigo cy’inshuti yanjye magara nzi imyaka 20, Bwana Dragan Domanovich. Nashimishijwe cyane n’icyuma cye cyo gukurura amajwi, tumaze kurangiza headphones ze, namubajije niba yakora amplifier ya SR1a, yashyirwaho ikimenyetso cya RAAL-requisite kandi igatangwa gusa nka RAAL-requisite. Yari afite amatsiko yo guhindura ibintu bikenewe ku topology ya amplifier akunda. Nyuma y’umwaka urenga, Dragan yabonye ijwi twese Rr na SAEQ twifuzaga. None SAEQ irashoboye, nabo barimo kurikora.”
Igice cy'imbere cya HSA-1b gifite switch y'amashanyarazi y'ubwoko bwa 5/8" y'umurambararo, imurikwa n'itara ritukura. Ku ruhande rw'iburyo hari connector ya XLR y'amajwi y'abagabo aho kuba iy'abagore basanzwe, bityo ni utwuma twa RAAL twa SR1a dukoreshwa mu guterura amajwi gusa; paki ya HSA-1b irimo adaptateri ya XLR y'abagore ihindura igitsina kugira ngo abayikoresha babashe guhuza Susvara ya HiFiMan ya 83dB/mW n'izindi ecouteur zikoresha ingufu nke kandi zikoresha ubukana buke kuri HSA-1b. SR1a itanga ingufu nyinshi, iburyo hari connector y'abagore y'amajwi y'abagabo asanzwe, hanyuma jack ya TRS ya 3.5mm (itaringaniye). Hejuru y'connector ya ecouteur hari umurongo w'amajwi atatu kugira ngo abayikoresha bahitemo hagati ya SR1a n'abakoresha ecouteur basanzwe. SR1a itanga umusaruro, ecouteur cyangwa speaker itanga umusaruro, inyinjizo ingana kandi idahuje. Ku ruhande rw'iburyo hari agapfundo k'inyuma k'umutuku gafite umuvuduko wo kugenzura ijwi rya HSA-1b, kagenzura gukanda kwayo. ijwi, agakoresho ko gupima amajwi gafite intambwe 24.
Radisavljevic yambwiye muri imeri ko HSA-1b ikoresha transistors za bipolar junction kuko "ari ibikoresho bikoresha umuriro, ntabwo ari ibikoresho bikoresha amashanyarazi nka MOSFET." Kubwibyo, "BJT zifite igihombo kinini cyo guhindura. Ariko ifite igihombo gito cyo kuyobora."
Nabwiye Radisavljevic "disiki itangaje" numvise kuri HSA-1b, itwara indangururamajwi ya 15 ohm, 83dB/2.83V/m?? Falcon LS3/5a, imbaraga zayo kandi byoroshye cyane. Namusabye gusobanura uburyo amplifier ye ntoya ya "ecouteur" ibikora. Yansubije ati: "Umushoferi arahari, kuko ashobora gutanga amps 7 ku mutwaro wa 0.4 ohm, bityo 15 ohms ntacyo bimubwiye. Muri make ni amplifier y'indangururamajwi yarushijeho kunozwa kugira ngo itware impedance nke. Irakora." Mu bundi butumwa bwa email, Aleksander yangejejeho bimwe mu bisobanuro bitarashyizwe ku rubuga rwa RAAL rugomba kugira: "Inyungu ni hafi 10dB y'inyongera ya RCA. Hamwe n'inyongera ya XLR, niba ufite DAC ifite umusaruro mwinshi, ushobora guhitamo kugabanya inyungu."
Imbere muri HSA-1b, akabaho gato kacapye kavuye ku kabaho k’injira ka XLR gafite switch ya DIP ifite imyanya itandatu, ishobora gukoreshwa mu "guhindura uburyo bwo kumva bwa XLR". Dukurikije amabwiriza, umukoresha afite amahitamo atatu: 10dB, 6dB, 0dB. Igikoresho cyanjye cyashyizweho kuri 6dB.
"Impedance y'umusaruro usanzwe [wa ecouteur] ni 5.3 ohms. Ingufu ziva kuri uyu musaruro zigera kuri 32 ohms ni 250mW, naho ingufu ziva kuri uyu musaruro zigera kuri 300 ohms ni 26mW. Ingufu ziva kuri SR-1a/Ribbon output (drive dynamic cyangwa planar magnetic Headphones)) 1900mW kuri 32 ohms na 200mW kuri 300 ohms." Niba imibare yanjye ari yo, bivuze ko switch yo guhindukira ibumoso ishyizwe ku mwanya wo hasi kandi umusaruro wa ribbon ni hafi 7.75V.
HSA-1b Ahandi muri iki kinyamakuru, ndimo gusuzuma indangururamajwi za Stenheim Suisse zo mu bwoko bwa aluminum zifite imyanya itatu zihagaze ku giciro cya $32.900 ku giciro cya kabiri. Izi ndangururamajwi ndende za santimetero 41 zisa n'izihenze cyane mu tubati twa aluminiyumu dutukura, umukara n'ikijuju. Isura yazo ni nziza cyane kandi igezweho. Icy'ingenzi kurushaho, zikora amajwi afite isura nziza kandi idahindagurika, ibi bikaba bishishikaje cyane.
Urubuga rwa Stenheim ruvuga ko ubushobozi bwo gukoresha Alumine Three ari 93dB/2.83V/m2 (amakuru ari hasi ku rupapuro rwa 3), kandi imbaraga nkeya za amplifier ni 10W. Rero, nkurikije uburyo bworoshye bwo kubyemeza, nagerageje kuzikoresha 10Wpc HSA-1b.
Birangora gufata icyemezo cyo gutangira igerageza ryanjye rya RAAL-Stenheim hamwe na Champion Jack Dupree cyangwa Jacqueline Du Pré. Uwo munsi hari hashyushye kandi huzuye umwuka, kandi umwuka wahumuraga nk'amafi, nuko njya muri Gutter Blues (16/44.1 FLAC Atlantic/Qobuz) hamwe n'igihangano cyakozwe na Jack Jerry Wexler, umukinnyi wa piyano wo muri New Orleans, mu 1958. Natunguwe n'ukuntu piyano ya Dupree yumvikana neza, n'ukuntu ijwi rya bass rya Wendell Marshall ryo muri Alumine Three's dual 8" ryumvikana neza. Imyitwarire ya Champion N'awlins iragaragara neza. Impungenge yanjye yonyine ni uburyo cyangwa impamvu ikunze kuba nziza cyane, amajwi akomeye yo muri Atlantike yumvikana neza kandi yoroshye.
Hanyuma nahindukiriye Jacqueline Du Pré, umucuranzi wa cellules uzwi cyane mu Bwongereza. Nacuranze Haydn na Mann: Cello Concerto, yo mu 1969 (24/48 FLAC-MQA Warner Classics / Tide), ubworoherane bwarashize, maze ibyiyumvo nyabyo byo gufunga no kugaragara biragaruka. Imirya ya London Symphony Orchestra iyobowe na Sir John Barbirolli iranyura neza kandi neza. HSA-1b + Alumine Three combination itanga ijwi rishya, rifunguye kandi risobanutse neza. Violin transiently na cello harmony byinjiye mu cyumba cyanjye, bifatika cyane. Iyi filime ntabwo ikunze kunshimisha cyane.
Mu gihe cy'igerageza kuva muri Kamena kugeza muri Nyakanga, numvise alubumu nyinshi, muri zo harimo RAAL HSA-1b yakoreshaga Stenheim Alumine Threes. Ni gake numva ko hakenewe imbaraga nyinshi.
SR1a HSA-1b ikenewe ya RAAL itwara indangururamajwi za Falcons na Stenheim neza cyane, ariko impamvu nyamukuru yo kubaho kwayo ni ugukoresha ecouteur za RAAL za SR1a zikozwe mu itsinda ryuzuye nta mashini ihindura impedance ya RAAL. Nizeye ko ishobora kuba ihuye na amplifier nakoze muri Pass Labs XA25 cyangwa Schiit Audio kuri SR1a (Jotunheim R.
Iyo Pass Labs XA25 ikoresheje icyuma cya RAAL (ikoresheje RAAL's impedance converter), amajwi yumvikana neza kandi yoroshye, kandi yumva ameze nk'aho ari yo mikoro yafashwe mbere, nta nkomyi. Umuziki wa trance nkunda ufite roho.
N'ibara. Ntabwo ari ikintu cya kera cyangwa ngo kibe nk'icy'amarangamutima mu gihe gishya. Ahubwo, kumva ubwirasi n'ubuhanga bibyutsa ibihe bya kera by'amaraso.
Ibi nibyo umupfumu w’ibidukikije Steve Roach yakoze muri alubumu ye yo mu 1993 yitwa Origins (16/44.1 FLAC Fortuna/Qobuz). Mu ndirimbo ya gatatu ya Origins yitwa "Clay, Wood, Bone, Dirt", amajwi yo hasi, ahum, n’ay’ijwi rya Daniel Nagle ya didgeridoo yarushaga andi majwi yose yakozwe n’abantu. Shyira imbaraga mu kwibuka amaraso. Hakoreshejwe SR1a iyobowe na HSA-1b, ijwi rirerire rya didgeridoo tube n’ijwi rigufi rya resonance y’inkono y’ibumba byagaragaye mu gice cy’uruziga imbere yanjye, bigaragara kandi bigaragara.

Nkuko bisanzwe, nkunda urugendo inyandiko yawe yatugejejeho. Jack Dupree, umukinnyi w’indashyikirwa, ubu arimo kurira aturutse mu ndangururamajwi zo mu cyumba cyanjye cyo kuraramo/mu biro (ni ikintu giteye agahinda), kandi ijwi rishobora kuba rihagije kugira ngo umugore, umwana muto n’umurera abana hasi bapfukame. Umunsi umwe, nifuzaga kumva urwego rw’iterambere rya ecouteur wanditse hano, ariko kugeza ubu, nasanze guhuza DragonFly Red na Sony MDR-7506 ari byo bituma inyungu igabanuka - $300! Najyanye Sony mu iduka ry’ibikoresho byo mu gace maze mbihuza na Focal Clears na Stellias ku gatebe kabo ka ecouteur, ariko sinashoboye gusobanura itandukaniro. Umucuruzi yansabye kugerageza DragonFly Red, byamfashije cyane; nashimishijwe cyane nyuma y’utubari duke twa mbere. Ijwi rya Blue riraruhutse cyane, ariko nk'umucuranzi w’ingoma (niba ari ubuzima bwa mbere muri iki gihe) nishimira ingaruka z’inyongera numva muri Red.
Yanditswe neza cyane, nkuko bisanzwe! Nk'umuntu ukunda Stax 9S, ndemeranya ko RAAL ishobora kuba ihamye kurushaho. Ubwo nageragezaga kuzigerageza, nasanze zishimishije. Mu by'ukuri, byaranshimishije cyane. Numvaga amatwi yanjye ari ku nkombe y'ingoma ya snare cyangwa saxophone. Ariko kuri ecouteur nke zihenze cyane (nka Ferrari), iyi ni inyongera itangaje. Murakoze!
Bwana HR, ndi umucuruzi wa Stax kandi nkunda cyane. Amaherezo, nagurishije Stax yanjye bwite kandi ndeka burundu kugurisha Stax.
Ibi bishobora kuba ari byiza, ariko si byo se? Birashoboka ko bigoye cyane, ari iby’umwuga cyane, bidasanzwe cyane, kandi biragoye cyane. Birashoboka ko ari nk’imodoka ya Porsche 911 Turbo ifata TacoBell kuri Drive through.
Umuziki ni nko kumarana igihe n'inshuti za kera, Stax Music ni nko gukemura ibibazo n'umusesenguzi wanjye.
Niba izi RAAL zisa na Stax, zishobora kugurishwa buhoro cyane ugereranije n'ibikoresho nka Diana of the Abyss. (Ndakeka)
Urakoze kutugezaho iyi raporo, sinshobora kwiyumvisha ko bashobora kwizera undi muntu uwo ari we wese. (Tyll ni lonnnnnnnnng Goooonnnnnnnn) Nubwo utatangajwe, usa nkaho uri umusimbura wa Tyll buri gihe.
Kuva nagura SR-5/SRD-6 hagati mu myaka ya za 70, nakoresheje ecouteur ya STAX. Hakurikiyeho Lambda Pro/SRD-7 Pro n'izindi seti nyinshi.
Ni izihe amplifiers ukoresha mu gutwara telefoni zigendanwa za STAX? Nasanze zimwe muri amplifiers za solid-state zifite ibibazo byo gutwara umutwaro utangwa na adaptateri ya STAX. Icyo gihe, SAE 31B yasaga nkaho ikora neza cyane, kandi Hafler DH-200 yagaragaye mu mpera z'ikinyejana.
Nishimiye Sennheiser zo ku rwego rwo hagati (uruhererekane rwa 580/600/650) na amplifiers za Schiit Class A SS na Schiit Valhalla 2 zifite imiyoboro y'Abarusiya (zituma umuziki urushaho kuryoha kandi uruhuka). Numvise ecouteur nshya kandi nziza, none ndimo ndatekereza kuri ABYSS Diana, ariko ntabwo ndimo kwihuta. Ndimo ndakurikirana kandi ndateganya verisiyo iheruka ya Woo Firefly.
Mu gihe cyanjye cyo kugurisha, Stax ni yo mashini yonyine mfite. Mfite ibikoresho byabo byo mu matwi n'ibikoresho by'ikoranabuhanga bihuye. Mbere ya RMAF mu 2011, nahuye na Schiit Guys. Nshishikajwe cyane na filozofiya yabo yo gukora no gushushanya. Ndi inzobere mu gushushanya no ...
Sennheiser ni nziza kurusha sisitemu iyo ari yo yose y'indangururamajwi nahuye nayo. (Nubwo ireme ry'amajwi yabo riri ku rwego rwo hagati ugereranije n'iry'igihe gishize, 1266 Abyss.)
PS Ndizera ko indangururamajwi za PS zo muri uru rukurikirane rwa FR zizakenerwa. Guhamagara intoki birahujwe!
