Ndisanayike RAAL HSA-1b, ndinali kusewera EMI LP yachilendo yotchedwa Renaissance Suite, yomwe inali ndi nyimbo kuchokera mu filimu ya Joël Santoni ya 1974 ya La Course en Tête (HQS 1415). Filimuyi ikufotokoza ntchito ya nyenyezi ya njinga ya ku Belgium Eddie Merkex m'njira yachilendo komanso yodabwitsa. Chinthu chachilendo kwambiri ndichakuti chigoli ichi chinapangidwa ndi kukonzedwa ndi katswiri wa nyimbo zoyambirira waku Britain David Munro, ndipo chinaseweredwa ndi London Early Music Union, yomwe ili ndi mphamvu zambiri. Tangoganizirani filimu yamasewera yokhala ndi mawu oimba chitoliro, tromba marina ("violin ya nun"), ndi rauschpfeiffen limodzi ndi anthu ovala zazifupi zothina ndi malaya owala okwera njinga zoonda m'mapiri a ku Europe.
Pogwiritsa ntchito 300B Elekit TU-8600 kuyendetsa LS3/5as, Renaissance Suite imawonetsa phokoso la zingwe zamatabwa ndi za m'mimba, zomwe zimapangitsa nyimbo zoyambirira za Munrow kumva ngati zenizeni, zakale komanso zachilendo. Ukali wake ndi watsopano komanso wachikondwerero, koma mawu ake ndi ofewa.
Pamene ndinalumikiza ma Gold Badges ku RAAL HSA-1b amplifier, mawuwo anayamba kukhala olimba komanso omveka bwino. Ndi HSA-1b, kuyenda ndi mphamvu ya nyimbo za sheet kumalamulira chikumbumtima changa. Nyimbo zimakhala zosinthasintha. Nyimbo zikamamveka bwino, ntchito ya David Munrow imakhala ndi tanthauzo lalikulu.
Ndikasintha kuchoka pa bokosi lamatabwa la Falcons kupita ku chowunikira makutu cha RAAL cha SR1a chotseguka kwambiri? Kuchokera pa zokamba ndi kupita ku zokamba makutu? Ndinaona bwino kwambiri "mawonekedwe" a chojambuliracho.
Chosinthira mawu cha RAAL chopangidwa ndi chitsulo chokhala ndi mutu wa khola ndi chapadera pamsika wa mahedifoni. Ndi cholimba komanso chotsika mtengo ($3,500). Tepi ya dipole ya SR1a imayikidwa mu khola lachitsulo chosapanga dzimbiri kutali ndi mutu. Ndi maliboni enieni, ndipo ma amplifiers omwe amapereka ali ndi kuletsa kwathunthu kwa katundu wafupikitsa: 0.2 ohms, kuphatikiza zingwe. Buku lothandizira limalimbikitsa kugwiritsa ntchito mphamvu ya amplifier ya 100W (pansi pa 1). Ndi madzi okwanira a amplifier, SR1a imapereka mawu okhazikika, opanda mtundu, komanso otsika omwe (ndikukhulupirira) amaposa Stax SR-009S static yapamwamba komanso JPS Labs Abyss AB-1266 Phi TC ndi HiFiMan Susvara planar magnetic element.
Mahedifoni a SR1a amafunika mphamvu zambiri zokulitsa mawu, kotero zikuwoneka kuti RAAL-requisite imapanga amplifier yomwe imatha kuyendetsa mahedifoni awo kapena ma speaker anga ndi kukhudza kamodzi kokha pagawo lakutsogolo.
Cholumikizira chatsopano cha HSA-1b cha HSA-1b cha RAAL (pansi pa tsamba 2) ndiye cholumikizira choyamba cha solid-state speaker ndi headphone chomwe ndayesa. Nditachilumikiza ku cholumikizira cha Stenheim Alumine Three chomwe chili pansi ndipo nditamva kuti chimatha kuyendetsa bwino ma speaker awiri amtengo wapatali US$32,900, ndinadziwa kuti chinali chosiyana ndi cholumikizira cha Linear Tube Audio cha 10Wpc (8 ohm) Z10e/ Headphone, ndinachiyang'ananso mu Gramophone Dreams #36 kapena Ampsandsound's 8Wpc (8 ohm) Bigger Ben, ndipo ndinachifotokoza mu Gramophone Dreams #47.
HSA-1b ya RAAL ndi amplifier yaying'ono yolimba yofanana ndi knob yofiira ya mapaundi 11.7 yokhala ndi kukula kocheperako, kutalika kwa mainchesi 3.5 x m'lifupi 8.6 x kuya kwa mainchesi 12.6. Imagwiritsa ntchito ma transistors awiri a bipolar junction (BJT) pa njira iliyonse. Ma bolt awiriwa amalumikizidwa ku radiator imodzi ya aluminiyamu ya mainchesi 8 × 3.5 × 2.
Ubwino wa kapangidwe kake ndi wapamwamba kwambiri kotero kuti HSA-1b ikuwoneka kuti ikukwaniritsa zofunikira zankhondo. M'mawonekedwe ake, kukwanira kwake kwakukulu komanso kumalizidwa kwake kumakhudza kulimba kwa mafakitale komanso kukongola kwa zokongoletsera zapakhomo.
Kuwonjezera pa (ndi pafupi) ndi soketi yamagetsi ya IEC yofunikira, gulu lakumbuyo la HSA-1b lili ndi zolowetsa ziwiri za mzere: single-end (RCA) ndi balanced (XLR). Palinso ma peya awiri a ma banana plug jacks olumikizira ma stereo speaker. Pansi pa speaker jack, pali mawu akuti "Serbian SAEQ yopangidwa ndikupangidwa kuti igwirizane ndi zofunikira za RAAL".
Malinga ndi Aleksandar Radisavljevic, mkulu wa RAAL-requisite, “SAEQ imayimira zida zamawu zaku Serbia. Ndi kampani ya bwenzi langa lapamtima lomwe ndalidziwa kwa zaka 20, a Dragan Domanovich. Ndachita chidwi kwambiri ndi amplifier yake ya speaker, titamaliza kulemba mahedifoni ake, ndinamufunsa ngati angapange amplifier ya SR1a, yomwe idzalembedwa kuti RAAL-requisite ndikuperekedwa kokha ngati RAAL-requisite. Anali wofunitsitsa kusintha zofunikira pa topology ya amplifier yake yomwe amakonda. Patatha chaka choposa kamodzi, Dragan adalandira phokoso lomwe tonsefe Rr ndi SAEQ tinkafuna. Tsopano popeza SAEQ ndi yokhoza, nawonso akupanga.
Gulu lakutsogolo la HSA-1b lili ndi chosinthira champhamvu cha mtundu wa audio cha mainchesi 5/8, choyatsidwa ndi nyali yofiira. Kumanja kwake kuli cholumikizira cha XLR cha mahedifoni anayi, chomwe ndi chachimuna osati chachikazi wamba, kotero kuti mahedifoni a RAAL a riboni a SR1a okha ndi omwe angalumikizidwe; phukusi la HSA-1b lili ndi adaputala ya XLR yachikazi yosintha jenda kukhala yachikazi kuti ogwiritsa ntchito athe kulumikiza mahedifoni a HiFiMan a 83dB/mW Susvara ndi mahedifoni ena ogwiritsira ntchito mphamvu komanso otsika ku HSA-1b. Chotulutsa cha SR1a champhamvu kwambiri, kumanja kuli cholumikizira chachikazi cha ma pin anayi cha mahedifoni achikhalidwe, kenako jeke ya TRS ya 3.5mm (yosalinganika). Pamwamba pa cholumikizira cha mahedifoni pali mzere wa ma switch atatu kuti ogwiritsa ntchito asankhe pakati pa SR1a ndi ma driver achikhalidwe a mahedifoni. Chotulutsa cha SR1a, chotulutsa mahedifoni kapena cholankhulira, cholowetsa bwino komanso chosalinganika. Kumanja kwenikweni kuli cholumikizira chachikulu chofiira cha HSA-1b, chomwe chimawongolera kudina kwake. phokoso, chochepetsera phokoso cha masitepe 24.
Radisavljevic anandiuza mu imelo kuti HSA-1b imagwiritsa ntchito ma transistors a bipolar junction chifukwa "ndi zipangizo zoyendetsedwa ndi magetsi, osati zipangizo zoyendetsedwa ndi magetsi monga MOSFET." Chifukwa chake, "ma BJT ali ndi kutayika kwakukulu kwa kusintha. Koma ali ndi kutayika kochepa kwa conduction."
Ndinauza Radisavljevic kuti "drive yodabwitsa" yomwe ndinamva kuchokera ku HSA-1b, ikuyendetsa sipika ya 15 ohm, 83dB/2.83V/m?? yomvera Falcon LS3/5a, mphamvu yake ndi yosavuta kudabwitsa. Ndinamufunsa kuti afotokoze momwe amplifier yake yaying'ono ya "headphone" imachitira izi. Iye anayankha kuti: "Driver ilipo, chifukwa imatha kupereka ma amps 7 ku load ya 0.4 ohm, kotero ma ohms 15 ndi opanda tanthauzo kwa iyo. Kwenikweni ndi amplifier ya sipika yomwe yakonzedwanso kuti iyendetse impedance yochepa. Lowetsani." Mu imelo ina, Aleksander anandidziwitsa zina zomwe sizinalembedwe patsamba la RAAL loyenera kukhala nalo: "Gain ndi pafupifupi 10dB ya RCA input. Ndi XLR input, ngati muli ndi DAC yotulutsa kwambiri, mutha kusankha kuchepetsa gain."
Mkati mwa HSA-1b, bolodi laling'ono losindikizidwa lomwe limatambasuka molunjika kuchokera ku bolodi lolowera la XLR lili ndi switch ya DIP yokhala ndi malo asanu ndi limodzi, yomwe ingagwiritsidwe ntchito "kusintha kwamkati kwa XLR input". Malinga ndi buku la malangizo, wogwiritsa ntchito ali ndi zisankho zitatu: 10dB, 6dB, 0dB. Chipangizo changa chili ndi 6dB.
"Kuletsa kutulutsa kwa [headphone] yachikhalidwe ndi 5.3 ohms. Mphamvu yochokera ku kutulutsa uku mpaka 32 ohms ndi 250mW, ndipo mphamvu yochokera ku kutulutsa uku mpaka 300 ohms ndi 26mW. Mphamvu yochokera ku kutulutsa kwa SR-1a/Ribbon (drive dynamic kapena planar magnetic Headphones)) 1900mW pa 32 ohms ndi 200mW pa 300 ohms." Ngati masamu anga ndi olondola, zikutanthauza kuti switch yakumanzere kwambiri yayikidwa pamalo otsika ndipo riboni yotuluka ndi pafupifupi 7.75V.
HSA-1b Kwinakwake mu nkhaniyi, ndikuwunikanso sipika ya Stenheim Suisse ya $32,900 pa awiri a aluminiyamu yokhala ndi mipando itatu pansi. Sipika zazitali izi za mainchesi 41 zimawoneka zodula kwambiri m'makabati a aluminiyamu ofiira, akuda ndi imvi. Mawonekedwe awo ndi okongola kwambiri komanso amakono. Chofunika kwambiri, amajambulanso zojambulira ndi zomveka bwino, zosayang'ana kung'anima, zomwe ndizosangalatsa kwambiri.
Webusaiti ya Stenheim imati mphamvu ya Alumine Three ndi 93dB/2.83V/m2 (mawu am'munsi 3), ndipo mphamvu yocheperako yomwe amplifier imalimbikitsa ndi 10W. Chifukwa chake, mwachibadwa, ndi mphamvu yopusa pang'ono, ndinayesa kuwagwiritsa ntchito ndi 10Wpc HSA-1b.
N'zovuta kwa ine kusankha ngati ndiyambe mayeso anga a RAAL-Stenheim ndi Champion Jack Dupree kapena Jacqueline Du Pré. Kunali kotentha komanso kodzaza tsiku limenelo, ndipo mpweya unali kununkha ngati nsomba, kotero ndinapita ku Gutter Blues (16/44.1 FLAC Atlantic/Qobuz) ndi luso lopangidwa ndi katswiri wa piyano wa ku New Orleans, Jack Jerry Wexler, mu 1958. Ndinadabwa momwe piyano ya Dupree imamvekera bwino, komanso momwe bass ya Wendell Marshall kuchokera ku Alumine Three's dual 8" woofers imamvekera. Khalidwe la Champion la N'awlins losakhazikika limaonekera bwino. Nkhawa yanga yokha ndi momwe nthawi zambiri zimakhala zowala komanso zofewa.
Kenako ndinatembenukira kwa Jacqueline Du Pré, woimba wotchuka kwambiri wa cell ku UK. Ndikusewera Haydn ndi Mann: Cello Concerto, kuyambira mu 1969 (24/48 FLAC-MQA Warner Classics/Tide), kufewa kunatha, ndipo tanthauzo lenileni la kutsekedwa ndi kupezeka linabweranso. Zingwe za London Symphony Orchestra zoyendetsedwa ndi Sir John Barbirolli zimadutsa ndi kaimidwe koyenera komanso molondola. Kuphatikiza kwa HSA-1b + Alumine Three kumapanga mawu atsopano, otseguka komanso omveka bwino. Violin transients ndi cello harmony zinalowa m'chipinda changa, zenizeni kwambiri. Kujambula kumeneku sikumveka kosangalatsa kwambiri.
Pa nthawi yoyeserera kuyambira mu June mpaka July, ndinamvetsera ma Albums ambiri, kuphatikizapo RAAL HSA-1b yomwe inkagwiritsa ntchito Stenheim Alumine Threes. Sindimamva kuti mphamvu zambiri zimafunika.
SR1a HSA-1b yofunikira ya RAAL imayendetsa bwino ma speaker a Falcons ndi Stenheim, koma chifukwa chachikulu chomwe chakhalapo ndikugwiritsa ntchito mahedifoni a RAAL a SR1a opanda RAAL amplifier impedance converter. Ndikukhulupirira kuti ikhoza kugwirizana ndi amplifier yomwe ndidapanga kuchokera ku Pass Labs XA25 kapena Schiit Audio ya SR1a (Jotunheim R.
Pamene Pass Labs XA25 imagwiritsa ntchito mahedifoni a RAAL (kudzera mu chosinthira cha impedance cha RAAL), kujambula kumamveka bwino komanso kolunjika, ndipo kumamveka ngati mawonekedwe oyamba, osatsekedwa omwe ajambulidwa ndi maikolofoni. Nyimbo ya trance yomwe ndimakonda ili ndi mzimu.
Ndipo mtundu. Sichikhala chakale kapena chosangalatsa mu nthawi yatsopano. M'malo mwake, kulimba mtima ndi kusinthasintha kumabweretsa zokumbukira zakale zamagazi.
Izi ndi zomwe mfiti ya chilengedwe Steve Roach adachita mu album yake ya 1993 ya Origins (16/44.1 FLAC Fortuna/Qobuz). Mu nyimbo yachitatu ya Origins ya "Clay, Wood, Bone, Dirt", mawu otsika, omveka bwino, komanso omveka bwino a didgeridoo a Daniel Nagle adapambana mawu ena onse opangidwa ndi anthu. Kulimbikitsa kukumbukira magazi. Pogwiritsa ntchito SR1a yoyendetsedwa ndi HSA-1b, kugwedezeka kwakutali kwa chubu cha didgeridoo ndi phokoso lalifupi la mphika wadothi zidawonekera mu semicircle patsogolo panga, zooneka bwino komanso zooneka bwino.

Mawu Otsindika 3: Ndikuyerekeza kuti mphamvu yamagetsi ya B-weighted ya Stenheim Alumine Three ndi 91dB/2.83V/m2, yomwe ndi yayikulu kwambiri kuposa avareji. ??John Atkinson
Monga mwachizolowezi, ndimakonda ulendo womwe nkhani yanu yatibweretsera. Jack Dupree, ngwazi tsopano akulira kuchokera kuma speaker m'chipinda changa chogona/ofesi (ndi tsoka lalikulu), ndipo phokoso lake lingakhale lokwanira kupangitsa mkazi, mwana wakhanda ndi wosamalira ana kukwinya nkhope. Tsiku lina, ndikanakonda kumva za kusintha kwa mahedifoni omwe mudalemba pano, koma mpaka pano, ndapeza kuti kuphatikiza kwa DragonFly Red ndi Sony MDR-7506 ndiye chifukwa chochepetsa phindu - $300! Ndinapita ndi Sony ku sitolo yakumaloko ndikuziphatikiza ndi Focal Clears ndi Stellias pa headphone bar yawo, koma sindinathe kufotokoza kusiyana kwake. Wogulitsayo anandipempha kuti ndiyesere DragonFly Red, zomwe zinandipindulitsa kwambiri; Ndinachita chidwi nditatha kugwiritsa ntchito ma headphone angapo oyamba. Mawu a Blue ndi omasuka kwambiri, koma monga woyimba zigoba (chabwino, moyo wakale panthawiyi) ndimasangalala ndi mphamvu yowonjezera yomwe imamveka kudzera mu Red.
Yalembedwa bwino kwambiri, monga nthawi zonse! Monga mwini/wokonda Stax 9S, ndikuvomereza kuti RAAL ikhoza kukhala yolimba mtima kwambiri. Nditayesa, ndinapeza kuti ndi yosangalatsa. Ndipotu, inali yosangalatsa kwambiri kwa ine. Ndinkamva kuti makutu anga anali m'mphepete mwa snare drum kapena saxophone. Koma pamahedifoni angapo apamwamba kwambiri (monga Ferrari), iyi ndi yowonjezera yodabwitsa. Zikomo!
Wokondedwa Bambo HR, ndine wogulitsa komanso wokonda Stax. Pamapeto pake, ndinagulitsa Stax yanga ndipo ndinasiya kugulitsa Stax.
Izi zitha kukhala zabwino, koma sichoncho? Mwina ndi zovuta kwambiri, zaukadaulo kwambiri, zapadera kwambiri, zovuta kwambiri. Mwina zili ngati Porsche 911 Turbo ikunyamula TacoBell pa Drive through.
Nyimbo zili ngati kucheza ndi anzanga akale, Stax Music ili ngati kuthetsa mavuto ndi katswiri wanga.
Ngati ma RAAL awa ali ofanana ndi Stax, angagulitsidwe pang'onopang'ono poyerekeza ndi zida monga Diana of the Abyss. (Ndikuganiza)
Zikomo potibweretsera lipotili, sindingathe kuganiza kuti angakhulupirire wina aliyense. (Tyll ndi lonnnnnnnnng Goooonnnnnnnn) Ngakhale simunalengezedwe, nthawi zonse mumawoneka kuti ndinu wolowa m'malo mwa Tyll.
Ndakhala ndikugwiritsa ntchito mahedifoni a STAX kuyambira pamene ndinagula SR-5/SRD-6 pakati pa zaka za m'ma 1970. Kenako panali Lambda Pro/SRD-7 Pro ndi ma seti ena angapo.
Ndi ma amplifiers ati omwe mumagwiritsa ntchito poyendetsa mafoni a STAX? Ndapeza kuti ma amplifiers ena a solid-state ali ndi mavuto poyendetsa katundu woperekedwa ndi adapter ya STAX. Panthawiyo, SAE 31B inkaoneka kuti ikugwira ntchito bwino kwambiri, ndipo Hafler DH-200 inaonekera kumapeto kwa zaka khumi.
Ndili wokondwa ndi ma Sennheiser apakatikati (580/600/650 series) ndi ma amplifiers a Schiit Class A SS ndi Schiit Valhalla 2 okhala ndi machubu aku Russia (amakweza nyimbo m'njira yabwino komanso yopumulira). Ndamva za mahedifoni atsopano komanso abwino, ndipo tsopano ndikuganizira za ABYSS Diana, koma sindikufulumira. Ndikutsata ndikukonzekera mtundu waposachedwa wa Woo Firefly.
Mu nthawi yanga yogulitsa, Stax ndiye mahedifoni okhawo omwe ndili nawo. Ndili ndi mahedifoni awo ndi zinthu zamagetsi zofanana. Ndisanachite RMAF mu 2011, ndinakumana ndi Schiit Guys. Ndimasangalala kwambiri ndi nzeru zawo zopangira zinthu ndi nzeru zawo. Ndine katswiri wa mahedifoni. Ndinagula zinthu zawo patatha miyezi ingapo. Ndimakondabe Schiit, ngakhale kuti dzina lawo ndi switch yawo yamagetsi zili kumbuyo.
Ma Sennheiser ndi abwino kuposa makina ena aliwonse olankhulira omwe ndakumana nawo. (Ngakhale kuti mawu awo ali pamlingo wapakati poyerekeza ndi abwino aposachedwa, 1266 Abyss.)
PS Ndikuyembekeza kuti ma speaker a PS a mndandanda wa FR adzafunika. Zala zoyimbirana zilumikizana!
