Ngaphambi nje kokuba ndifake i-RAAL HSA-1b, bendidlala i-EMI LP engaqhelekanga ebizwa ngokuba yiRenaissance Suite, eyayiquka umculo ovela kwifilimu kaJoël Santoni ka-1974 ethi La Course en Tête (HQS 1415). Le filimu irekhoda umsebenzi wenkwenkwezi yebhayisekile yaseBelgium u-Eddie Merkex ngendlela engaqhelekanga nemangalisayo yobugcisa. Eyona nto ingaqhelekanga kukuba le score yaqanjwa yaza yahlelwa yingcali yomculo wokuqala waseBritane uDavid Munro, yaze yadlalwa yiLondon Early Music Union, egcwele amandla. Khawuthelekelele idokhumentari yezemidlalo eneesandi zokudlala iflute, itromba marina ("i-violin ka-nun"), kunye ne-rauschpfeiffen ehamba nabantu abanxibe iibhulukhwe ezimfutshane eziqinileyo kunye neehempe ezikhanyayo bekhwele iibhayisekile ezincinci kwiinduli zaseYurophu.
Isebenzisa i-300B Elekit TU-8600 ukuqhuba i-LS3/5as, iRenaissance Suite ibonisa isandi somthi kunye neentambo zamathumbu, okwenza umculo wokuqala kaMunrow ubonakale ungowokwenyani, wamaxesha aphakathi kwaye ungaqhelekanga. Umsindo wayo utsha kwaye unemibhiyozo, kodwa ilizwi layo lithambile.
Xa ndiqhagamshela iiGold Badges kwi-RAAL HSA-1b amplifier, isandi saba siqinile kwaye sicacile ngakumbi. Nge-HSA-1b, ukuhamba kunye nomfutho womculo wephepha kulawula ingqondo yam. Umculo unamandla ngakumbi. Xa umculo uphezulu, umsebenzi kaDavid Munrow uba nentsingiselo ngakumbi.
Xa nditshintsha ukusuka kwibhokisi yomthi yeFalcons ukuya kwi-RAAL's SR1a evulekileyo ngokupheleleyo ye-ear monitor? Ukusuka kwi-speakers ukuya kwi-earbud speakers? Ndifumene "umbono" ocacileyo nogxile ngakumbi werekhodi.
I-transducer ye-RAAL efakwe entloko yekheyiji yentsimbi ikhethekile kwimarike yee-earphone. Zihlala ixesha elide kwaye zifikeleleka ngexabiso eliphantsi ($3,500). Iteyiphu ye-dipole ye-SR1a ibekwe kwikheyiji yentsimbi engagqwaliyo kude nentloko. Ziiribhoni zokwenyani, kwaye ii-amplifiers ezizibonisayo zine-impedance yomthwalo we-short-circuit epheleleyo: 0.2 ohms, kuquka neentambo. Incwadi yomsebenzisi icebisa ukusetyenziswa kwamandla e-amplifier ye-100W (umbhalo osemazantsi 1). Ngejusi ye-amplifier eyaneleyo, i-SR1a inika amanqanaba esandi aqinileyo, angenambala, aphantsi okuphambuka (ndikholelwa) adlula i-static ye-super-resolution ye-Stax SR-009S kunye ne-JPS Labs Abyss AB-1266 Phi TC kunye ne-HiFiMan Susvara planar magnetic element.
Ii-headphone ze-SR1a zifuna amandla amaninzi e-amplifier enamandla, ngoko ke kubonakala kusengqiqweni ukuba i-RAAL-requisite yenze i-amplifier ekwaziyo ukuqhuba ii-headphones okanye izithethi zam ngokuchukumisa nje iswitshi kwiphaneli engaphambili.
I-amplifier entsha ye-HSA-1b RAAL (umbhalo osemazantsi 2) yeyona amplifier yokuqala yesithethi esiqinileyo kunye ne-headphone endiyizamile. Xa ndayiqhagamshela kwisithethi esimi phantsi iStenheim Alumine Three ndaza ndeva ukuba inokuqhuba ngokufanelekileyo izithethi ezimbini ezixabisa i-US$32,900, ndazi ukuba luhlobo olwahlukileyo lwesithethi kwi-amplifier ye-Linear Tube Audio ye-10Wpc (8 ohm) Z10e/ Headphone ye-Linear Tube Audio, ndayijonga kwi-Gramophone Dreams #36 okanye kwi-8Wpc (8 ohm) Bigger Ben ye-Ampsandsound, ndaza ndayichaza kwi-Gramophone Dreams #47.
I-RAAL's HSA-1b sisixhobo sokukhulisa esibomvu esincinci esiqinileyo esinobukhulu obuphakathi, ubude obuyi-3.5" x ububanzi obuyi-8.6" x ubunzulu obuyi-12.6". Isebenzisa ii-transistors ezimbini ze-bipolar junction (BJT) kwitshaneli nganye. Ezi zibhanti ziqhagamshelwe kwiradiator enye ye-aluminium eyi-8" × 3.5" × 2".
Umgangatho wokwenziwa kwemveliso uphezulu kakhulu kangangokuba kwimeko yayo, i-HSA-1b ibonakala ihlangabezana neemfuno zomkhosi. Ngokwembonakalo, umgangatho ophezulu wokufaneleka kunye nokugqitywa kunento ebalulekileyo kumandla emizi-mveliso kunye nomtsalane wokuhombisa ikhaya.
Ukongeza kwi (kwaye ecaleni) kwesokethi yamandla ye-IEC eyimfuneko, iphaneli yangasemva ye-HSA-1b inezingeniso ezimbini zenqanaba lomgca: i-single-end (RCA) kunye ne-balanced (XLR). Kukwakho nee-pair ezimbini zee-banana plug jacks zokudibanisa izithethi ze-stereo. Phantsi kwe-speaker jack, ifundeka ngolu hlobo "i-Serbian SAEQ yenzelwe kwaye yenzelwe iimfuno ze-RAAL".
Ngokutsho kuka-Aleksandar Radisavljevic, intloko yazo zonke izixhobo ze-RAAL-requisite, “i-SAEQ imele izixhobo zesandi zaseSerbia. Yinkampani yomhlobo wam endimaziyo iminyaka engama-20, uMnu. Dragan Domanovich. Ndichukumiseke kakhulu sisandi sakhe sesandi, emva kokuba sigqibile ii-headphones zakhe, ndambuza ukuba angenza na isandi se-SR1a, esiza kumakishwa njenge-RAAL-requisite kwaye sinikelwe kuphela njenge-RAAL-requisite. Wayenomdla wokwenza utshintsho olufunekayo kwi-topology yesandi sakhe asithandayo. Emva konyaka ongaphezulu kwesiqhelo, uDragan wafumana isandi esasifunwa sithi sonke thina Rr kunye ne-SAEQ. Ngoku ekubeni i-SAEQ ikwazi, nabo bayayenza.”
Iphaneli engaphambili ye-HSA-1b ineswitshi yamandla yohlobo lwesandi sobuchwephesha obuyi-5/8" ububanzi, ekhanyiswe sisibane esibomvu. Ngasekunene kwayo kukho isixhumi se-XLR see-headphone esiphumayo esineepin ezine, esiyindoda kunokuba sibe sesetyhini esiqhelekileyo, ukuze kuqhagamshelwe kuphela ii-earphone zeribhoni ze-RAAL ze-SR1a; iphakheji ye-HSA-1b ibandakanya i-adaptha ye-XLR yomfazi etshintsha isini ukuya kwesetyhini ukuze abasebenzisi bakwazi ukuqhagamshela i-Susvara ye-HiFiMan ye-83dB/mW kunye nezinye ii-earphone ezisebenzisa amandla, ezibuthathaka kwi-HSA-1b. Isiphumo se-SR1a esiphezulu, ngasekunene kukho isixhumi se-female esineepin ezine zee-earphone zendabuko ezilinganisiweyo, kunye ne-jack ye-TRS ye-3.5mm (engalinganiyo). Ngaphezulu kwesixhumi see-earphone kukho umqolo weeswitshi ezintathu abasebenzisi abanokukhetha kuzo phakathi kwe-SR1a kunye nabaqhubi be-earphone bendabuko. Isiphumo se-SR1a, isiphumo see-headphone okanye isithethi, igalelo elilinganisiweyo nelingalinganiyo. Ngasekunene kakhulu kukho iqhosha elikhulu levolumu yokulawula iphaneli ebomvu ye-HSA-1b, elawula ukucofa kwayo. isandi, i-attenuator enamanyathelo angama-24.
URadisavljevic undixelele kwi-imeyile ukuba i-HSA-1b isebenzisa ii-transistors ze-bipolar junction kuba "zizixhobo eziqhutywa ngumbane, azizo izixhobo eziqhutywa ngumbane ezifana nee-MOSFET." Ngenxa yoko, "ii-BJT zinelahleko eziphezulu zokutshintsha. Kodwa inelahleko ezincinci zokuqhuba."
Ndixelele iRadisavljevic "idrayivu emangalisayo" endiyivileyo kwi-HSA-1b, iqhuba isithethi seFalcon LS3/5a esine-15 ohm, 83dB/2.83V/m?, amandla ayo kwaye kulula ngokumangalisayo. Ndimcelile ukuba achaze indlela i-amplifier yakhe encinci "yee-headphone" ekwenza ngayo oku. Uphendule wathi: "Umqhubi ukhona, kuba unokubonelela ngee-amps ezi-7 kumthwalo we-0.4 ohm, ngoko ke ii-ohms ezili-15 azinantsingiselo kuyo. Ngokusisiseko yi-amplifier yesithethi ephuculwe ngakumbi ukuqhuba i-impedance ephantsi. Layisha." Kwenye i-imeyile, uAleksander wandazisa kwiinkcukacha ezingadweliswanga kwiwebhusayithi ye-RAAL ekufuneka ibe nayo: "Inzuzo imalunga ne-10dB yengeniso ye-RCA. Ngengeniso ye-XLR, ukuba une-DAC ephezulu, ungakhetha ukunciphisa inzuzo."
Ngaphakathi kwi-HSA-1b, ibhodi yesekethe encinci eprintiweyo ephuma ngokuthe nkqo kwibhodi yokufaka ye-XLR ineswitshi ye-DIP eneendawo ezintandathu, enokusetyenziswa "kuhlengahlengiso lwangaphakathi lovakalelo lokufakwa kwe-XLR". Ngokwencwadi yemiyalelo, umsebenzisi unokukhetha oku-3: 10dB, 6dB, 0dB. Isixhobo sam simiselwe kwangaphambili kwi-6dB.
"I-output impedance yemveliso yesiqhelo [yee-headphone] yi-5.3 ohms. Amandla avela kule mveliso ukuya kwi-32 ohms yi-250mW, kwaye amandla avela kule mveliso ukuya kwi-300 ohms yi-26mW. Amandla avela kwi-SR-1a/Ribbon output (ii-drive dynamic okanye ii-planar magnetic Headphones)) yi-1900mW kwi-32 ohms kunye ne-200mW kwi-300 ohms." Ukuba izibalo zam zichanekile, kuthetha ukuba iswitshi yokutshintshela ekhohlo isetelwe kwindawo yokuhla kwaye isiphumo seribhoni simalunga ne-7.75V.
I-HSA-1b Kwenye indawo kule ngxaki, ndihlaziya isithethi sikaStenheim Suisse esixabisa i-$32,900/isibini se-aluminium esinezihlalo ezintathu esime phantsi. Ezi zithethi zinde ezingama-41 intshi zibukeka zibiza kakhulu kwiikhabhathi ze-aluminium ezibomvu, ezimnyama nezingwevu. Inkangeleko yazo imnandi kakhulu kwaye inamhla. Okubaluleke kakhulu, ziphinda zirekhodiwe ngendlela ecacileyo, engaguqukiyo, nto leyo enomdla kakhulu.
Iwebhusayithi kaStenheim ithi uvakalelo lwe-Alumine Three yi-93dB/2.83V/m (umbhalo osemazantsi 3), kwaye amandla amancinci acetyiswayo e-amplifier yi-10W. Ngoko ke, ngokwemvelo, ngokundikhuthaza kancinci, ndazama ukuzinika amandla nge-10Wpc HSA-1b.
Kunzima kum ukugqiba ukuba ndiqale na uvavanyo lwam lweRAAL-Stenheim kunye noChampion Jack Dupree okanye uJacqueline Du Pré. Kwakushushu kwaye kugcwele ngaloo mini, kwaye umoya wawunuka njengentlanzi, ngoko ke ndaya kwiGutter Blues (16/44.1 FLAC Atlantic/Qobuz) kunye nomsebenzi wobugcisa owenziwe yintshatsheli yepiyano yaseNew Orleans uJack Jerry Wexler ngo-1958. Ndamangaliswa yindlela ipiyano kaDupree eyayivakala kamnandi ngayo, kunye nendlela ibhesi kaWendell Marshall etyebileyo neyinyani ngayo evela kwi-Alumine Three's dual 8" woofers eyayivakala ngayo. Isimo sengqondo sikaChampion sikaN'awlins esiguquguqukayo sibonakala ngokupheleleyo. Ingxaki yam kuphela kukuba ingaba njani okanye kutheni idla ngokuba njani iirekhodi zeAtlantic ezinzima zivakala zixinene kwaye zithambile.
Emva koko ndajika ndaya kuJacqueline Du Pré, umdlali we-cell odumileyo e-UK. Ndidlala uHaydn noMann: Cello Concerto, ukususela ngo-1969 (24/48 FLAC-MQA Warner Classics/Tide), ukuthamba kwaphela, kwaye ingqiqo yokwenyani neyokwenyani yokuvaleka kunye nokuba khona yabuya. Iintambo zeLondon Symphony Orchestra eziqhutywa nguSir John Barbirolli zidlula ngendlela efanelekileyo kunye nokuchaneka. Indibaniselwano ye-HSA-1b + Alumine Three ivelisa isandi esitsha, esivulekileyo nesicacileyo. I-violin transients kunye ne-cello harmony zingene kwigumbi lam, ziyinyani kakhulu. Olu rekhodi alufane luvakale lunomtsalane kangaka.
Ngexesha lovavanyo ukususela ngoJuni ukuya kuJulayi, ndimamele amacwecwe amaninzi, phakathi kwawo iRAAL HSA-1b yayisebenzisa iStenheim Alumine Threes. Andiva ukuba kufuneka amandla angakumbi.
I-SR1a HSA-1b efunekayo ye-RAAL iqhuba kakuhle izithethi zeFalcons kunye neStenheim, kodwa esona sizathu sokubakho kwayo kukunika amandla ii-headphone ze-RAAL ze-SR1a ezipheleleyo ngaphandle kwe-RAAL amplifier impedance converter. Ndiyathemba ukuba inokuhambelana ubuncinane ne-amplifier endiyenzileyo kwi-Pass Labs XA25 okanye kwi-Schiit Audio ye-SR1a (Jotunheim R.
Xa iPass Labs XA25 inika amandla i-headset ye-RAAL (nge-RAAL's impedance converter), ukurekhoda kuvakala kucacile kwaye kuthe ngqo, kwaye kuvakala ngathi ngumbono wokuqala, ongenaziphazamiso othathwe yimakrofoni. Umculo we-trance endiwuthandayo unomphefumlo.
Kwaye umbala. Akukaze kube yinto yakudala okanye enomtsalane kwixesha elitsha. Endaweni yoko, imvakalelo yokuba ngqongqo kwaye ikhawuleza ivuselela iinkumbulo ezindala zegazi.
Yile nto kanye eyenziwa yingcali yokusingqongileyo uSteve Roach kwi-albhamu yakhe ka-1993 ethi Origins (16/44.1 FLAC Fortuna/Qobuz). Kwingoma yesithathu ye-Origins ethi "Clay, Wood, Bone, Dirt", izandi eziphantsi, ezihumzayo, nezivakalayo zikaDaniel Nagle ze-didgeridoo zibetha zonke ezinye izandi ezenziwe ngumntu. Khuthaza inkumbulo yegazi. Ukusebenzisa i-SR1a eqhutywa yi-HSA-1b, isandi esifutshane se-flutter cavity resonance yetyhubhu ye-didgeridoo kunye nesandi esifutshane se-resonance sembiza yodongwe sabonakala kwi-semicircle phambi kwam, sibambeka kwaye sibambeka.

Inqaku elisezantsi 3: Ndiqikelela ukuba uvakalelo lwe-voltage ye-B-weighted yeStenheim Alumine Three yi-91dB/2.83V/m2, ephezulu kakhulu kunomndilili. ??John Atkinson
Njengesiqhelo, ndiyawuthanda uhambo olusiphathele lona eli nqaku. Intshatsheli uJack Dupree ngoku uyakhala kwizipikha kwigumbi lam lokulala/eofisini (yintlekele), kwaye isandi sinokwanela ukwenza umfazi, umntwana omncinci kunye nomnakekeli womntwana bafinge iintshiya phantsi. Ngenye imini, ndingathanda ukuva malunga nokuphuculwa kwee-headphones ozibhalileyo apha, kodwa ukuza kuthi ga ngoku, ndifumanise ukuba indibaniselwano yeDragonFly Red kunye neSony MDR-7506 yeyona nto ibangela ukuba imbuyekezo inciphe - $300! Ndathatha iSony ndaya evenkileni yendawo ndaza ndazidibanisa neFocal Clears kunye neStellias kwi-headphone bar yazo, kodwa andikwazanga ukucacisa umahluko. Umthengisi undicele ukuba ndizame iDragonFly Red, eyandinceda kakhulu; ndachukumiseka emva kwee-bar ezimbalwa zokuqala. Ilizwi likaBlue likhululekile ngakumbi, kodwa njengomdlali we-percussion (ewe, ubomi bangaphambili ngeli xesha) ndiyayonwabela impembelelo eyongezelelweyo eviwa yiRed.
Ibhalwe kakuhle kakhulu, njengesiqhelo! Njengomnini/umthandi weStax 9S, ndiyavuma ukuba iRAAL isenokuba nokuzimisela ngakumbi. Xa ndazama, ndazifumana zinomdla. Enyanisweni, zazindichulumancisa kakhulu. Ndavakalelwa kukuba iindlebe zam zazikwicala ledrama okanye i-saxophone. Kodwa kwii-headphones ezimbalwa ze-super premium (ezifana neFerrari), olu longezo lumangalisayo. enkosi!
Mnumzana HR othandekayo, ndingumsasazi kwaye ndingumntu othanda iStax. Ekugqibeleni, ndithengise iStax yam kwaye ndayeka ukuthengisa iStax kwaphela.
Oku kusenokuba yinto entle, kodwa akunjalo? Mhlawumbi iyinkimbinkimbi kakhulu, inobungcali kakhulu, ikhethekile kakhulu, inzima kakhulu. Mhlawumbi kufana nePorsche 911 Turbo ethatha iTacoBell kwiDrive through.
Umculo ufana nokuchitha ixesha nabahlobo bakudala, iStax Music ifana nokusombulula iingxaki nomhlalutyi wam.
Ukuba ezi RAAL zifana neStax, zinokuthengiswa kancinci kakhulu xa zithelekiswa nezixhobo ezifana neDiana of the Abyss. (Ndicinga)
Enkosi ngokusiphathela le ngxelo, andinakucinga ukuba banokumthemba omnye umntu. (UTyll ungumntu olungileyo) Nangona ungabhengezwanga, uhlala ubonakala ngathi ungumntu oza kuthatha indawo kaTyll.
Ndingumsebenzisi wee-headset ze-STAX ukusukela oko ndathenga i-SR-5/SRD-6 phakathi kwiminyaka yoo-1970. Ilandelwa yiLambda Pro/SRD-7 Pro kunye nezinye iiseti ezininzi.
Zeziphi ii-amplifiers ozisebenzisayo ukuqhuba iifowuni ze-STAX? Ndifumanise ukuba ezinye ii-amplifiers ze-solid-state zineengxaki zokuqhuba umthwalo obonelelwa yi-adaptha ye-STAX. Ngelo xesha, i-SAE 31B yayibonakala isebenza kakuhle kakhulu, kwaye iHafler DH-200 yavela ekupheleni kweminyaka elishumi.
Ndonwabe ngeeSennheiser eziphakathi (uthotho lwe-580/600/650) kunye nee-amplifiers zeSchiit Class A SS kunye neSchiit Valhalla 2 ezineetyhubhu zaseRashiya (ziphakamisa umculo ngendlela ekhululekileyo nephumzayo). Ndivile ngee-headphones ezintsha nezimnandi, kwaye ngoku ndicinga nge-ABYSS Diana, kodwa andingxamanga. Ndilandela kwaye ndicwangcisa inguqulelo yamva nje yeWoo Firefly.
Kwixesha lam lokuthengisa, iStax phantse yeyona headset ndinayo. Ndinee-headset zabo kunye neemveliso ze-elektroniki ezifanayo. Ngaphambi kweRMAF ngo-2011, ndadibana neSchiit Guys. Ndinomdla kakhulu kwifilosofi yabo yokuvelisa kunye nefilosofi. Ndinguchwephesha kwii-headphone. Ndathenga iimveliso zabo emva kweenyanga ezimbalwa. Ndisamthanda uSchiit, nangona igama labo kunye neswitshi yombane zingasemva.
IiSennheiser zingcono kunayo nayiphi na inkqubo yesithethi endikhe ndadibana nayo. (Nangona umgangatho wesandi sabo ukwinqanaba eliphakathi xa kuthelekiswa nento yamva nje elungileyo, i-1266 Abyss.)
PS Ndilindele ukuba izithethi zesandi zePS zolu thotho lweFR ziya kufuneka. Iminwe edibeneyo!
