Ua ntej kuv teeb tsa RAAL HSA-1b, kuv tab tom ua si EMI LP txawv txawv hu ua Renaissance Suite, uas suav nrog suab paj nruag los ntawm Joël Santoni zaj yeeb yaj kiab xyoo 1974 La Course en Tête (HQS 1415). Zaj yeeb yaj kiab no sau txog txoj haujlwm ntawm Belgian lub hnub qub tsheb kauj vab Eddie Merkex hauv txoj kev kos duab txawv txawv thiab zoo kawg nkaus. Qhov txawv tshaj plaws yog tias cov qhab nia no tau tsim thiab npaj los ntawm tus kws tshaj lij suab paj nruag thaum ub Askiv David Munro, thiab ua yeeb yam los ntawm London Early Music Union, uas muaj lub zog. Xav txog ib daim ntawv qhia txog kev ua si uas muaj suab ntawm kev ua si lub raj nplaim, tromba marina ("nun's violin"), thiab rauschpfeiffen nrog cov neeg hnav ris luv nruj thiab lub tsho ci ntsa iab caij tsheb kauj vab nyias nyias ntawm cov roob ntawm Tebchaws Europe.
Siv 300B Elekit TU-8600 los tsav LS3/5as, Renaissance Suite qhia lub suab ntawm ntoo thiab cov hlua plab, ua rau Munrow cov suab paj nruag thaum ub zoo li tiag tiag, medieval thiab txawv txawv. Nws lub siab tshiab thiab lom zem, tab sis nws lub suab mos mos.
Thaum kuv txuas Gold Badges rau lub amplifier RAAL HSA-1b, lub suab tau ruaj khov thiab meej dua. Nrog HSA-1b, qhov ntws thiab lub zog ntawm daim ntawv suab paj nruag tswj hwm kuv lub siab. Suab paj nruag muaj zog dua. Thaum suab paj nruag nrov dua, David Munrow txoj haujlwm muaj lub ntsiab lus ntau dua.
Thaum kuv hloov ntawm Falcons lub thawv ntoo mus rau RAAL's SR1a lub mloog pob ntseg qhib dav dav? Los ntawm cov neeg hais lus mus rau cov neeg hais lus pob ntseg? Kuv tau pom "kev pom" meej dua thiab tsom mus rau qhov kev kaw suab.
RAAL lub taub hau hlau cage transducer yog tshwj xeeb hauv kev lag luam pob ntseg. Lawv ruaj khov thiab pheej yig ($ 3,500). Daim kab xev dipole ntawm SR1a tau muab tso rau hauv lub tawb hlau stainless kom deb ntawm lub taub hau. Lawv yog cov ribbons tiag tiag, thiab cov amplifiers uas lawv nthuav tawm muaj qhov luv luv impedance yuav luag tiav: 0.2 ohms, suav nrog cov cables. Phau ntawv qhia siv pom zoo kom siv 100W amplifier zog (footnote 1). Nrog txaus amplifier kua txiv, SR1a muab cov suab nrov concentrated, tsis muaj xim, qis-distortion uas (kuv ntseeg) tshaj qhov super-resolution Stax SR-009S static thiab kuv tus hlub JPS Labs Abyss AB-1266 Phi TC thiab HiFiMan Susvara planar magnetic element.
Cov mloog pob ntseg SR1a xav tau lub zog amplifier siab heev, yog li nws zoo li muaj laj thawj uas RAAL-yuav tsum tsim cov amplifier uas tuaj yeem tsav lawv cov mloog pob ntseg lossis kuv cov neeg hais lus nrog ib qho kov ntawm lub qhov hloov ntawm lub vaj huam sib luag pem hauv ntej.
HSA-1b RAAL lub HSA-1b amplifier tshiab (footnote 2) yog thawj lub solid-state speaker thiab headphone amplifier uas kuv tau sim. Thaum kuv txuas nws rau lub floor-standing Stenheim Alumine Three speaker thiab hnov tias nws tuaj yeem tsav ob lub speakers uas muaj nqis US $ 32,900, kuv paub tias nws yog ib hom speaker txawv ntawm Linear Tube Audio's 10Wpc (8 ohm) Z10e/ Headphone amplifier, kuv tau tshuaj xyuas nws hauv Gramophone Dreams # 36 lossis Ampsandsound's 8Wpc (8 ohm) Bigger Ben, thiab kuv tau piav qhia nws hauv Gramophone Dreams # 47.
RAAL's HSA-1b yog lub amplifier me me liab uas ruaj khov thiab hnyav 11.7 phaus nrog qhov loj nruab nrab, siab 3.5" x dav 8.6" x tob 12.6". Nws siv ob lub transistors bipolar junction (BJT) rau txhua txoj channel, Ob lub bolts txuas nrog ib lub radiator txhuas 8" × 3.5" × 2".
Qhov zoo ntawm kev tsim khoom yog siab heev uas hauv nws rooj plaub, HSA-1b zoo li ua tau raws li cov qauv tub rog. Hauv qhov tsos, qib siab ntawm kev haum thiab tiav muaj ob qho tib si qhov hnyav ntawm kev lag luam thiab kev zoo nkauj ntawm kev kho kom zoo nkauj hauv tsev.
Ntxiv rau (thiab nyob ib sab ntawm) lub qhov hluav taws xob IEC uas yuav tsum tau ua, lub vaj huam sib luag tom qab ntawm HSA-1b muaj ob lub qhov nkag kab: ib qho kawg nkaus (RCA) thiab ib qho sib npaug (XLR). Kuj tseem muaj ob khub ntawm cov qhov ntsaws txiv tsawb rau txuas cov neeg hais lus stereo. Hauv qab lub qhov ntsaws lub hais lus, nws nyeem "Serbian SAEQ tsim thiab tsim rau RAAL cov kev cai".
Raws li Aleksandar Radisavljevic, tus thawj coj ntawm txhua yam RAAL-requisite, "SAEQ sawv cev rau Serbian audio equipment. Nws yog ib lub tuam txhab ntawm ib tug phooj ywg zoo heev uas kuv tau paub txog 20 xyoo, Mr. Dragan Domanovich. Kuv zoo siab heev nrog nws lub tshuab hais lus amplifier, thaum peb ua tiav nws lub mloog pob ntseg, kuv nug nws seb nws puas tuaj yeem ua lub amplifier rau SR1a, uas yuav raug cim tias yog RAAL-requisite thiab muab tsuas yog RAAL-requisite. Nws xav ua qhov kev hloov kho tsim nyog rau topology ntawm nws lub amplifier nyiam. Tom qab ntau tshaj ib xyoos, Dragan tau txais lub suab uas peb txhua tus Rr thiab SAEQ xav tau. Tam sim no SAEQ muaj peev xwm, lawv kuj ua nws.
Lub vaj huam sib luag pem hauv ntej ntawm HSA-1b muaj lub qhov hloov fais fab 5/8 "txoj kab uas hla kev tshaj lij suab hom, ci los ntawm lub teeb liab. Ntawm nws sab xis yog plaub-pin XLR lub mloog pob ntseg tso zis connector, uas yog txiv neej es tsis yog poj niam ib txwm, Yog li ntawd tsuas yog RAAL's SR1a ribbon earphones tuaj yeem txuas nrog; HSA-1b pob suav nrog poj niam hloov poj niam mus rau poj niam XLR adapter kom cov neeg siv tuaj yeem txuas HiFiMan's 83dB / mW Susvara thiab lwm yam hwj chim siv, qis-sensitivity earphones rau HSA-1b. Lub siab-tam sim no SR1a tso zis, ntawm sab xis yog plaub-pin poj niam connector ntawm cov pob ntseg sib npaug ib txwm muaj, thiab tom qab ntawd 3.5mm (tsis sib npaug) TRS jack. Saum toj no lub pob ntseg earphone yog ib kab ntawm peb lub qhov hloov rau cov neeg siv xaiv ntawm SR1a thiab cov tsav tsheb pob ntseg ib txwm muaj. SR1a tso zis, lub mloog pob ntseg lossis lub tso zis hais lus, sib npaug thiab tsis sib npaug. Ntawm sab xis deb yog lub vaj huam sib luag liab loj tswj ntim pob ntawm HSA-1b, uas tswj nws lub suab nyem, 24-kauj ruam tus ua kom lub zog poob qis.
Radisavljevic tau hais rau kuv hauv email tias HSA-1b siv cov transistors bipolar junction vim "lawv yog cov khoom siv uas tsav los ntawm tam sim no, tsis yog cov khoom siv uas tsav los ntawm voltage zoo li MOSFETs." Yog li ntawd, "BJTs muaj kev poob qis dua ntawm kev hloov pauv. Tab sis nws muaj kev poob qis dua."
Kuv hais rau Radisavljevic txog "kev tsav tsheb zoo kawg nkaus" uas kuv hnov los ntawm HSA-1b, nws tab tom tsav lub 15 ohm, 83dB / 2.83V / m ?? Falcon LS3 / 5a lub tso suab, nws lub zog thiab yooj yim xav tsis thoob. Kuv nug nws kom piav qhia txog nws lub amplifier me me "lub mloog pob ntseg" ua qhov no li cas. Nws teb tias: "Tus tsav tsheb nyob ntawd, vim tias nws tuaj yeem muab 7 amps rau 0.4 ohm load, yog li 15 ohms tsis muaj txiaj ntsig rau nws. Nws yog qhov tseem ceeb rau lub tso suab amplifier uas tau raug kho kom zoo dua los tsav qis impedance. Load." Hauv lwm email, Aleksander tau qhia kuv txog qee cov lus qhia tsis tau teev nyob rau hauv RAAL yuav tsum muaj lub vev xaib: "Qhov nce yog li 10dB ntawm RCA input. Nrog XLR input, yog tias koj muaj DAC siab, koj tuaj yeem xaiv kom txo qhov nce."
Sab hauv HSA-1b, ib lub rooj tsavxwm me me uas txuas ncaj qha los ntawm lub rooj tsavxwm XLR muaj lub qhov hloov DIP rau qhov chaw, uas siv tau rau "kev hloov kho qhov rhiab heev sab hauv ntawm XLR input". Raws li phau ntawv qhia, tus neeg siv muaj 3 txoj kev xaiv: 10dB, 6dB, 0dB. Kuv lub cuab yeej tau teeb tsa ua ntej rau 6dB.
"Qhov tso zis impedance ntawm cov zis [lub mloog pob ntseg] ib txwm yog 5.3 ohms. Lub zog los ntawm qhov tso zis no mus rau 32 ohms yog 250mW, thiab lub zog los ntawm qhov tso zis no mus rau 300 ohms yog 26mW. Lub zog tso zis ntawm SR-1a / Ribbon tso zis (tsav dynamic lossis planar magnetic Headphones)) 1900mW ntawm 32 ohms thiab 200mW ntawm 300 ohms." Yog tias kuv lej yog qhov tseeb, nws txhais tau tias sab laug toggle switch tau teeb tsa rau qhov chaw qis thiab cov zis ribbon yog li 7.75V.
Hauv tsab ntawv xov xwm no, kuv tab tom tshuaj xyuas Stenheim Suisse lub tshuab hais lus peb lub rooj zaum uas muaj nqi $32,900/ib khub uas yog txhuas. Cov tshuab hais lus siab 41-nti no zoo li kim heev hauv cov txee txhuas liab, dub thiab grey. Lawv cov tsos zoo nkauj thiab niaj hnub heev. Qhov tseem ceeb tshaj plaws, lawv ua cov ntaub ntawv kaw suab nrog lub suab meej thiab tsis muaj kev cuam tshuam, uas yog qhov txaus nyiam heev.
Lub vev xaib Stenheim hais tias qhov rhiab heev ntawm Alumine Three yog 93dB / 2.83V / m (footnote 3), thiab lub zog tsawg kawg nkaus pom zoo ntawm lub amplifier yog 10W. Yog li ntawd, nrog me ntsis kev ntxias tsis zoo, kuv sim muab lub zog rau lawv nrog 10Wpc HSA-1b.
Nws nyuaj rau kuv txiav txim siab seb puas yuav pib kuv qhov kev sim RAAL-Stenheim nrog Champion Jack Dupree lossis Jacqueline Du Pré. Hnub ntawd kub thiab tsis muaj zog, thiab huab cua tsw zoo li ntses, yog li kuv mus rau Gutter Blues (16/44.1 FLAC Atlantic/Qobuz) nrog lub suab zoo kawg nkaus uas tus yeej pianist New Orleans Jack Jerry Wexler ua hauv xyoo 1958. Kuv xav tsis thoob tias Dupree lub piano suab qab zib npaum li cas, thiab lub suab bass ntawm Wendell Marshall los ntawm Alumine Three's dual 8" woofers suab nplua nuj thiab muaj tseeb npaum li cas. Champion tus cwj pwm wobbly N'awlins tau pom tag nrho. Kuv tsuas yog txhawj xeeb yog vim li cas lossis vim li cas nws feem ntau ci ntsa iab Atlantic cov ntaub ntawv suab me ntsis tuab thiab mos.
Tom qab ntawd kuv tig mus rau Jacqueline Du Pré, tus kws ntaus cello nto moo tshaj plaws hauv UK. Ua si nws Haydn thiab Mann: Cello Concerto, los ntawm xyoo 1969 (24/48 FLAC-MQA Warner Classics / Tide), qhov mos mos ploj mus, thiab qhov tseeb thiab qhov tseeb ntawm kev sib tsoo thiab kev muaj nyob rov qab los. Cov hlua ntawm London Symphony Orchestra coj los ntawm Sir John Barbirolli dhau nrog qhov kev sawv ntsug thiab kev raug. HSA-1b + Alumine Peb ua ke tsim cov suab tshiab, qhib thiab meej. Violin transients thiab cello harmony nkag mus rau hauv kuv chav, muaj tseeb heev. Cov ntaubntawv povthawj no tsis tshua muaj kev xav zoo li ntawd.
Thaum lub sijhawm audition txij lub Rau Hli mus txog rau Lub Xya Hli, kuv tau mloog ntau lub albums, ntawm cov uas RAAL HSA-1b siv Stenheim Alumine Threes. Kuv tsis tshua xav tias xav tau lub zog ntxiv.
RAAL qhov tsim nyog SR1a HSA-1b tsav Falcons thiab Stenheim cov neeg hais lus zoo heev, tab sis qhov laj thawj tseem ceeb rau nws qhov muaj nyob yog kom muaj zog rau RAAL's SR1a full-band headphones yam tsis muaj RAAL amplifier impedance converter. Kuv vam tias nws yuav tsawg kawg sib xws nrog lub amplifier uas kuv ua los ntawm Pass Labs XA25 lossis Schiit Audio rau SR1a (Jotunheim R.
Thaum Pass Labs XA25 muab lub zog rau RAAL lub mloog pob ntseg (ntawm RAAL's impedance converter), cov ntaubntawv povthawj suab meej thiab ncaj nraim, thiab nws zoo li thawj, tsis muaj kev cuam tshuam uas lub microphone ntes tau. Cov suab paj nruag trance uas kuv nyiam muaj tus ntsuj plig.
Thiab xim. Nws yeej tsis yog ib yam qub qub los yog muaj kev xav hauv lub caij nyoog tshiab. Hloov chaw, qhov kev xav ntawm kev ua tib zoo thiab kev txawj ntse ua rau muaj kev nco txog cov ntshav qub.
Qhov no yog qhov uas tus kws txawj ua kom ib puag ncig zoo Steve Roach tau ua hauv nws daim album xyoo 1993 Origins (16/44.1 FLAC Fortuna/Qobuz). Hauv Origins zaj nkauj thib peb "Clay, Wood, Bone, Dirt", Daniel Nagle lub suab didgeridoo qis, hum, thiab guttural yeej txhua lub suab uas tib neeg tsim. Txhawb kom nco qab ntshav. Siv SR1a tsav los ntawm HSA-1b, lub suab ntev flutter ntawm lub raj didgeridoo thiab lub suab luv luv ntawm lub lauj kaub av nplaum tau tshwm sim hauv lub voj voog ib nrab ntawm kuv xub ntiag, pom tseeb thiab pom tseeb.

Ib yam li niaj zaus, kuv nyiam txoj kev uas koj tsab xov xwm tau coj peb los. Tus yeej Jack Dupree tam sim no quaj los ntawm cov neeg hais lus hauv kuv chav pw / chaw ua haujlwm (nws yog qhov tu siab), thiab lub suab yuav txaus kom ua rau tus poj niam, menyuam yaus thiab tus neeg saib xyuas menyuam hauv qab nthab ntsej muag. Muaj ib hnub, kuv xav hnov txog qib kev txhim kho ntawm lub mloog pob ntseg uas koj tau sau ntawm no, tab sis txog tam sim no, kuv tau pom tias kev sib xyaw ua ke ntawm DragonFly Red thiab Sony MDR-7506 yog qhov taw tes ntawm kev txo qis rov qab-$ 300! Kuv coj Sony mus rau lub khw muag khoom hauv zos thiab muab lawv ua ke nrog Focal Clears thiab Stellias ntawm lawv lub mloog pob ntseg, tab sis tsis tuaj yeem piav qhia qhov sib txawv. Tus neeg muag khoom tau hais kom kuv sim DragonFly Red, uas tau pab kuv ntau; Kuv xav tsis thoob tom qab thawj ob peb kab. Blue lub suab yog so ntau dua, tab sis ua tus neeg ntaus suab paj nruag (zoo, lub neej yav dhau los ntawm lub sijhawm no) Kuv nyiam qhov cuam tshuam ntxiv hnov los ntawm Red.
Sau tau zoo heev, ib yam li niaj zaus! Ua tus tswv/tus neeg nyiam Stax 9S, kuv pom zoo tias RAAL tej zaum yuav txiav txim siab ntau dua. Thaum kuv sim lawv, kuv pom lawv zoo siab heev. Qhov tseeb, nws zoo siab heev rau kuv. Kuv xav tias kuv pob ntseg nyob ntawm ntug ntawm lub nruas snare lossis saxophone. Tab sis rau ob peb lub mloog pob ntseg zoo heev (xws li Ferrari), qhov no yog qhov ntxiv zoo kawg nkaus. ua tsaug!
Nyob zoo Mr. HR, kuv yog ib tus neeg faib khoom thiab tus neeg nyiam Stax. Thaum kawg, kuv muag kuv tus kheej Stax thiab tsis muag Stax li lawm.
Qhov no tej zaum yuav yog ib qho zoo, tab sis puas yog? Tej zaum nws nyuaj dhau, ua haujlwm dhau, tshwj xeeb dhau, thiab nyuaj dhau. Tej zaum nws zoo li Porsche 911 Turbo khaws TacoBell ntawm Drive thru.
Suab paj nruag zoo li nyob nrog cov phooj ywg qub, Stax Music zoo li daws teeb meem nrog kuv tus kws tshuaj ntsuam.
Yog tias cov RAALs no zoo ib yam li Stax, lawv yuav muag qeeb heev piv rau cov khoom siv xws li Diana ntawm Abyss. (Kuv xav li ntawd).
Ua tsaug rau koj coj daim ntawv qhia no tuaj rau peb, kuv tsis xav tias lawv yuav ntseeg lwm tus. (Tyll yog lonnnnnnnng Gooooonnnnnnn) Txawm hais tias tsis tau tshaj tawm, koj zoo li ib txwm yog Tyll hloov.
Txij li thaum kuv yuav lub SR-5/SRD-6 thaum nruab nrab xyoo 1970s, kuv tau siv lub mloog pob ntseg STAX. Tom qab ntawd yog Lambda Pro/SRD-7 Pro thiab ntau lwm yam khoom siv.
Koj siv cov amplifiers twg los tsav STAX xov tooj ntawm tes? Kuv pom tias qee cov solid-state amplifiers muaj teeb meem tsav lub nra hnyav uas muab los ntawm STAX adapter. Lub sijhawm ntawd, SAE 31B zoo li ua haujlwm zoo heev, thiab Hafler DH-200 tau tshwm sim thaum kawg ntawm kaum xyoo.
Kuv zoo siab nrog cov Sennheisers nruab nrab (580/600/650 series) thiab Schiit Class A SS amplifiers thiab Schiit Valhalla 2 nrog cov raj Lavxias (lawv ua rau suab paj nruag zoo thiab so). Kuv tau hnov txog cov mloog pob ntseg tshiab thiab zoo, thiab tam sim no kuv tab tom xav txog ABYSS Diana, tab sis kuv tsis maj. Kuv tab tom ua raws thiab npaj qhov tseeb version ntawm Woo Firefly.
Hauv kuv lub sijhawm muag khoom, Stax yuav luag yog tib lub mloog pob ntseg uas kuv muaj. Kuv muaj lawv cov koob mloog pob ntseg thiab cov khoom siv hluav taws xob sib phim. Ua ntej RMAF hauv xyoo 2011, kuv tau ntsib Schiit Guys. Kuv txaus siab rau lawv lub tswv yim thiab kev xav txog kev tsim khoom. Kuv yog tus kws tshaj lij mloog pob ntseg. Kuv yuav lawv cov khoom ob peb lub hlis tom qab. Kuv tseem nyiam Schiit, txawm tias lawv lub npe thiab lub qhov hluav taws xob nyob tom qab.
Sennheisers zoo dua li lwm lub tshuab hais lus uas kuv tau ntsib. (Txawm hais tias lawv lub suab zoo nyob rau theem nruab nrab piv rau qhov zoo tshiab, 1266 Abyss.)
PS Kuv xav tias cov neeg hais lus PS ntawm FR series yuav tsim nyog. Cov ntiv tes hu xov tooj sib txuas!
