Ndisati ndaisa RAAL HSA-1b, ndaitamba firimu reEMI risingawanzoitiki rinonzi Renaissance Suite, raisanganisira mimhanzi kubva mufirimu raJoël Santoni ra1974 rinonzi La Course en Tête (HQS 1415). Iyi firimu inonyora basa remutambi webhasikoro wekuBelgium Eddie Merkex nenzira inoshamisa uye inoshamisa yeunyanzvi. Chinhu chinoshamisa ndechekuti chibodzwa ichi chakanyorwa uye chakarongwa nenyanzvi yemimhanzi yekutanga yekuBritain David Munro, uye chakaimbwa neLondon Early Music Union, iyo izere nesimba. Fungidzira dhirama remitambo rine ruzha rwekuridza flute, tromba marina ("nun's violin"), uye rauschpfeiffen achiperekedzwa nevanhu vakapfeka mashoti mapfupi nehembe dzakajeka vakatasva mabhasikoro matete mumakomo eEurope.
Ichishandisa 300B Elekit TU-8600 kutyaira LS3/5as, Renaissance Suite inoratidza ruzha rwehuni netambo dzemudumbu, zvichiita kuti mimhanzi yekutanga yaMunrow iite seyechokwadi, yekare uye inoshamisa. Hunhu hwayo hutsva uye hwemutambo, asi inzwi rayo rakapfava.
Pandakabatanidza maGold Badges neRAAL HSA-1b amplifier, ruzha rwacho rwakawedzera kusimba uye kujeka. NeHSA-1b, kufamba kwemimhanzi uye simba remimhanzi zvinodzora pfungwa dzangu. Mimhanzi inowedzera simba. Kana mimhanzi ichinzwika zvakanyanya, basa raDavid Munrow rinowedzera kukosha.
Pandinochinja kubva pabhokisi rehuni reFalcons kuenda kuRAAL's SR1a wide-open full-band ear monitor? Kubva kumaspika kuenda kumaearbud speakers? Ndakaona "maonero" akajeka uye akanyatsotarisa kurekodha.
Transducer yeRAAL ine simbi yakaiswa mumusoro ine musika wema earphone. Inogara kwenguva refu uye inodhura ($3,500). Tepi yedipole yeSR1a yakaiswa mukeji yesimbi isina ngura kure nemusoro. Iwo ma ribhoni chaiwo, uye ma amplifiers avari kupa ane short-circuit load impedance yakakwana: 0.2 ohms, kusanganisira tambo. Bhuku rekushandisa rinokurudzira kushandiswa kwesimba re amplifier re100W (peji 1). Nejusi re amplifier rakakwana, SR1a inopa manzwi akasimba, asina ruvara, uye asina kukanganiswa zvakanyanya ayo (ndinotenda) anopfuura super-resolution Stax SR-009S static uye JPS Labs Abyss AB-1266 Phi TC uye HiFiMan Susvara planar magnetic element.
Mahedhifoni eSR1a anoda simba re amplifier rine simba guru, saka zvinoita sezvine musoro kuti RAAL-requisite igadzire amplifier inogona kutyaira mahedhifoni avo kana maspika angu nekubata kamwe chete kweswitch panel yekumberi.
HSA-1b RAAL's HSA-1b amplifier itsva (pasi pechidzidzo 2) ndiyo yekutanga solid-state speaker ne headphone amplifier yandakaedza. Pandakaibatanidza neStenheim Alumine Three speaker yakamira pasi ndikanzwa kuti inogona kufambisa maspika maviri anokosha US$32,900, ndakaziva kuti yaive mhando yakasiyana yespeaker kubva kuLinear Tube Audio's 10Wpc (8 ohm) Z10e/ Headphone amplifier, ndakaiongorora muGramophone Dreams #36 kana kuti Ampsandsound's 8Wpc (8 ohm) Bigger Ben, uye ndakaitsanangura muGramophone Dreams #47.
HSA-1b yeRAAL i amplifier diki diki dzvuku ine jira re 11.7 pound ine saizi iri pakati nepakati, 3.5" yakakwirira x 8.6" yakafara x 12.6" yakadzika. Inoshandisa ma transistors maviri e bipolar junction (BJT) kune chiteshi chimwe nechimwe. Mabhoti maviri aya akabatanidzwa kune radiator imwe chete ye 8" × 3.5" × 2" yearuminiyamu.
Hunhu hwekugadzira hwakakwirira zvekuti kana iri, HSA-1b inoita seinosangana nezvinodiwa nemauto. Pachitarisiko, kukodzera kwayo kwepamusoro uye kupedzisa kwayo zvine simba guru remaindasitiri uye runako rwekushongedza imba.
Pamusoro pe (uye padyo) nesoketi yemagetsi yeIEC inodiwa, panel yekumashure yeHSA-1b ine ma inputs maviri e level line: imwe ine end (RCA) uye ine balanced (XLR). Kunewo mapeya maviri ema banana plug jacks ekubatanidza ma stereo speakers. Pasi pe speaker jack, pane mavara anoti "Serbian SAEQ yakagadzirwa uye yakagadzirwa zvinoenderana nezvinodiwa neRAAL".
Sekureva kwaAleksandar Radisavljevic, mukuru wezvese zvinodikanwa zveRAAL, "SAEQ inomiririra michina yekuteerera yeSerbia. Ikambani yeshamwari yangu yepamoyo yandagara ndichiziva kwemakore makumi maviri, VaDragan Domanovich. Ndafadzwa zvikuru ne amplifier yake yespeaker, patapedza kupedza mahedhifoni ake, ndakamubvunza kana aigona kugadzira amplifier yeSR1a, iyo yaizonyorwa seRAAL-requisite uye yaizopihwa chete seRAAL-requisite. Aida kugadzirisa zvinodiwa pa topology ye amplifier yake yaaida. Mushure meanopfuura gore. Zvakare, Dragan akawana ruzha rwaida isu tese Rr naSAEQ. Zvino zvave kugona kweSAEQ, vari kuigadzirawo."
Panel yepamberi yeHSA-1b ine switch yemagetsi yemhando ye professional audio type 5/8" dhayamita, inovhenekerwa nechiedza chitsvuku. Kurudyi kwayo kune connector ye XLR headphone output connector ine pin ina, inova yemurume kwete yemukadziwo zvake, kuitira kuti mahedhifoni eRAAL's SR1a ribbon chete akwanise kubatanidzwa; HSA-1b package ine adapter ye XLR yemukadzi inochinja murume nemukadzi kuitira kuti vashandisi vagone kubatanidza HiFiMan's 83dB/mW Susvara nedzimwe earphones dzinodya simba uye dzisinganyanyi kunzwiwa neHSA-1b. SR1a output ine simba rakawanda, kurudyi kune connector yemukadzi ine pin ina yema earphones akajairwa, uye ipapo jack yeTRS ye3.5mm (isina kuenzana). Pamusoro pe earphone connector pane mutsara we switch nhatu dzevashandisi dzekusarudza pakati peSR1a nemadhiraivha earphone akajairwa. SR1a output, mahedhifoni kana speaker output, input yakaenzana uye isina kuenzana. Kurudyi kure kune bhodhi hombe tsvuku yekutonga vhoriyamu yeHSA-1b, iyo inodzora kudzvanya kwayo. ruzha, chinhu chinoderedza ruzha chine matanho makumi maviri nemana.
Radisavljevic akandiudza mu email kuti HSA-1b inoshandisa bipolar junction transistors nekuti "idzo imidziyo inotungamirwa nemagetsi, kwete midziyo inotungamirwa nemagetsi seMOSFET." Saka, "BJTs dzine kurasikirwa kwakanyanya kwekuchinja. Asi ine kurasikirwa kwakaderera kwekufambisa magetsi."
Ndakaudza Radisavljevic kuti "dhiraivha inoshamisa" yandakanzwa kubva kuHSA-1b, iri kutyaira spika ye15 ohm, 83dB/2.83V/m?? inonzwisisika yeFalcon LS3/5a, simba rayo uye iri nyore kushamisa. Ndakamubvunza kuti atsanangure kuti amplifier yake diki ye "headphone" inoita sei izvi. Akapindura achiti: "Driver iripo, nekuti inogona kupa 7 amps kune 0.4 ohm load, saka 15 ohms haina zvazvinoreva. Chaizvoizvo i spika amplifier yakagadziriswazve kuti ishandise low impedance. Load." Mune imwe email, Aleksander akandizivisa kune mamwe ma specs asina kunyorwa pawebhusaiti yeRAAL must-have: "Gain inenge 10dB yeRCA input. Ne XLR input, kana uine high-output DAC, unogona kusarudza kuderedza gain."
Mukati meHSA-1b, bhodhi diki redunhu rakadhindwa rinotambanudzwa rakatarisa kubva pabhodhi rekuisa reXLR rine switch yeDIP ine nzvimbo nhanhatu, iyo inogona kushandiswa "kugadzirisa kunzwisisika kwemukati kwekupinda kweXLR". Sekureva kwebhuku remirayiridzo, mushandisi ane sarudzo nhatu: 10dB, 6dB, 0dB. Chishandiso changu chakagadziriswa ku6dB.
"Kuvharirwa kwesimba remagetsi kubva pa [headphones] yechinyakare i5.3 ohms. Simba kubva pamagetsi aya kusvika pa32 ohms i250mW, uye simba kubva pamagetsi aya kusvika pa300 ohms i26mW. Simba remagetsi kubva paSR-1a/Ribbon output (drive dynamic kana planar magnetic Headphones)) 1900mW pa32 ohms uye 200mW pa300 ohms." Kana masvomhu angu ari echokwadi, zvinoreva kuti switch yekurudyi yakaiswa panzvimbo yekudzika uye ribhoni output inenge 7.75V.
HSA-1b Mune imwe nyaya iri mumagazini ino, ndiri kuongorora sipika yeStenheim Suisse yemadhora zviuru makumi matatu nemazana mapfumbamwe ($32,900) paaruminiyamu ine zvigaro zvitatu. Aya masipika akareba masendimita makumi mana nerimwe anotaridzika kunge anodhura zvikuru mumakabati ealuminium matsvuku, matema uye grey. Chitarisiko chawo chinonaka uye chemazuva ano. Chinonyanya kukosha ndechekuti anoburitsa zvakarekodhwa zvine kujeka, kusingapindi, izvo zvinonakidza zvikuru.
Webhusaiti yaStenheim inoti kunzwisiswa kweAlumine Three i93dB/2.83V/m (mashoko emuzasi 3), uye simba rinokurudzirwa reamplifier i10W. Saka, nekunyengetedza kusina kunaka, ndakaedza kuashandisa ne10Wpc HSA-1b.
Zvakaoma kuti ndisarudze kana ndotanga RAAL-Stenheim bvunzo yangu naChampion Jack Dupree kana Jacqueline Du Pré. Kwaipisa uye kwakazara nemhepo musi iwoyo, uye mhepo yainhuwirira sehove, saka ndakaenda kuGutter Blues (16/44.1 FLAC Atlantic/Qobuz) neunyanzvi hwakagadzirwa naJack Jerry Wexler, shasha yepiyano yeNew Orleans, muna 1958. Ndakashamisika kuti piyano yaDupree yainzwika sei, uye kuti bass yaWendell Marshall kubva kuAlumine Three's dual 8" woofers yainzwika sei. Maitiro aChampion N'awlins anoderera anoratidzwa zvizere. Chinhu chimwe chete chandinongonetseka nacho ndechekuti kazhinji marekodhi eAtlantic anonzwika sei, akakora uye akapfava.
Ndakabva ndatendeukira kuna Jacqueline Du Pré, mutambi wecello ane mukurumbira muUK. Ndichiridza Haydn naMann: Cello Concerto, kubva muna 1969 (24/48 FLAC-MQA Warner Classics/Tide), kupfava kwacho kwakabva kwanyangarika, uye pfungwa chaiyo yekuvharika nekuvapo yakadzoka. Nziyo dzeLondon Symphony Orchestra dzaitungamirwa naSir John Barbirolli dzakapfuura nechimiro chakakodzera uye nemazvo. Musanganiswa weHSA-1b + Alumine Three unoburitsa ruzha rutsva, rwakavhurika uye rwakajeka. Violin transients uye cello harmony zvakapinda mukamuri mangu, zviri zvechokwadi. Iyi rekodhi haiwanzonzwika seinokwezva kudaro.
Munguva yekuyedzwa kubva muna Chikumi kusvika Chikunguru, ndakateerera maalbum akawanda, pakati pawo RAAL HSA-1b yaishanda neStenheim Alumine Threes. Handiwanzo funga kuti simba rakawanda rinodiwa.
SR1a HSA-1b inodiwa yeRAAL inofambisa zvakanaka maspika eFalcons neStenheim, asi chikonzero chikuru chekuvapo kwayo ndechekupa simba kumahedhifoni eRAAL eSR1a azere pasina RAAL amplifier impedance converter. Ndinovimba inogona kuenderana neamplifier yandakaita kubva kuPass Labs XA25 kana Schiit Audio yeSR1a (Jotunheim R.
Kana Pass Labs XA25 ikashandisa RAAL headset (kuburikidza neRAAL's impedance converter), kurekodha kunonzwika kwakajeka uye kwakananga, uye kunoita sekunge maonero ekutanga, asina kuvharwa atorwa nemaikorofoni. Mimhanzi yetrance yandinoda ine mweya.
Uye ruvara. Hazvimbofi zvakagara kwenguva refu kana kuti zvine manzwiro munguva itsva. Asi, pfungwa yekushanda nesimba uye kugona kunounza ndangariro dzekare dzine ropa.
Izvi ndizvo chaizvo zvakaitwa nenyanzvi yezvezvakatipoteredza Steve Roach mu album yake ya1993 inonzi Origins (16/44.1 FLAC Fortuna/Qobuz). Murwiyo rwechitatu rweOrigins rwekuti "Clay, Wood, Bone, Dirt", ruzha rwaDaniel Nagle rwe "didgeridoo" rwakaderera, rwunonzwika, uye rwunonzwika muguttural rwakakunda mamwe manzwi ese akagadzirwa nevanhu. Kurudzira ndangariro yeropa.

Semazuva ese, ndinofarira rwendo rwatakapihwa nechinyorwa chako. Jack Dupree, shasha iri kuchema kubva kumaspika ari muimba yangu yekurara/hofisi (inhamo), uye ruzha rwacho runogona kukwana kuita kuti mudzimai, mwana mudiki uye muchengeti wemwana vakwenye chiso. Rimwe zuva, ndaizoda kunzwa nezvekuvandudzwa kwemahedhifoni awakanyora pano, asi kusvika pari zvino, ndakaona kuti kusanganiswa kweDragonFly Red neSony MDR-7506 ndiko kunoita kuti mari yekudzoka iderere - $300! Ndakaenda neSony kuchitoro chemunharaunda ndikavasanganisa neFocal Clears naStellias pahedhifoni yavo, asi handina kukwanisa kutsanangura musiyano wacho. Mutengesi akandikumbira kuti ndiedze DragonFly Red, izvo zvakandibatsira zvikuru; ndakafadzwa mushure memabhawa ekutanga mashoma. Inzwi raBlue rakasununguka, asi semutambi wengoma (zvakanaka, hupenyu hwekare panguva ino) ndinofarira simba rakawedzerwa rinonzwiwa kuburikidza neRed.
Zvakanyorwa zvakanaka kwazvo, semazuva ese! Semuridzi/mudi weStax 9S, ndinobvumirana kuti RAAL inogona kunge yakatsunga. Pandakaedza, ndakaiwana ichifadza. Kutaura zvazviri, zvaindifadza zvikuru. Ndakanzwa kuti nzeve dzangu dzaive pamucheto wedhiramu resnare kana saxophone. Asi kune mahedhifoni mashoma epamusoro (akadai seFerrari), ichi chinhu chinoshamisa. Makorokoto!
Vadiwa VaHR, ndiri mugovanisi uye ndinoyemura Stax. Pakupedzisira, ndakatengesa Stax yangu uye ndakarega kutengesa Stax zvachose.
Izvi zvingava zvakanaka, asi handiti? Pamwe zvakaoma, zvine hunyanzvi, zvakasiyana, zvinonetsa. Pamwe zvakaita sePorsche 911 Turbo iri kutora TacoBell paDrive through.
Mimhanzi yakaita sekugara neshamwari dzekare, Stax Music yakaita sekugadzirisa matambudziko nemuongorori wangu.
Kana maRAAL aya akafanana neStax, anogona kutengeswa zvishoma nezvishoma kana tichienzanisa nemidziyo yakaita seDiana of the Abyss. (Ndinofunga)
Tinokutendai nekutiunzira mushumo uyu, handifungi kuti vanogona kuvimba nemumwe munhu. (Tyll ndiye akavimbika. Goooonnnnnnnn) Kunyangwe usati waziviswa, unoita sekuti ndiwe unotsiva Tyll.
Ndanga ndichishandisa mahedhifoni eSTAX kubvira pandakatenga SR-5/SRD-6 pakati pemakore ekuma1970. Ichiteverwa neLambda Pro/SRD-7 Pro nedzimwe seti dzakasiyana siyana.
Ndeapi ma amplifiers aunoshandisa kutyaira nharembozha dzeSTAX? Ndakaona kuti mamwe ma amplifiers e solid-state ane matambudziko ekutyaira mutoro wakapihwa ne STAX adapter. Panguva iyoyo, SAE 31B yairatidzika kunge inoshanda zvakanaka, uye Hafler DH-200 yakaonekwa pakupera kwemakore gumi.
Ndiri kufara nemaSennheiser epakati (580/600/650 series) nemaSchiit Class A SS amplifiers uye Schiit Valhalla 2 ane machubhu ekuRussia (anoridza mimhanzi zvakanaka uye zvinozorodza). Ndakanzwa nezvemahedhifoni matsva uye akanaka, uye ikozvino ndiri kufunga nezveABYSS Diana, asi handisi kukurumidza. Ndiri kutevera uye kuronga vhezheni yazvino yeWoo Firefly.
Munguva yangu yekutengesa, Stax ndiyo yega mahedhifoni andinawo. Ndine mahedhifoni avo uye zvigadzirwa zvemagetsi zvinoenderana. Ndisati ndatanga RMAF muna 2011, ndakasangana neSchiit Guys. Ndinofarira zvikuru uzivi hwavo hwekugadzira uye uzivi. Ndiri nyanzvi yemahedhifoni. Ndakatenga zvigadzirwa zvavo mwedzi mishoma gare gare. Ndichiri kuda Schiit, kunyangwe zita ravo neswitch yavo yemagetsi zviri kumashure.
Sennheiser iri nani pane chero sisitimu yemaspika yandakasangana nayo. (Kunyangwe hunhu hweruzha rwavo huri padanho repakati kana tichienzanisa nehwechizvino-zvino, 1266 Abyss.)
PS Ndinotarisira kuti maspika ePS eakatevedzana eFR achadikanwa. Kufona-minwe kwakabatana!
