Ma mua pono o koʻu hoʻokomo ʻana iā RAAL HSA-1b, e pāʻani ana au i kahi LP EMI ʻano ʻē i kapa ʻia ʻo Renaissance Suite, nona nā mele mai ke kiʻiʻoniʻoni 1974 a Joël Santoni ʻo La Course en Tête (HQS 1415). Hoʻopaʻa kēia kiʻiʻoniʻoni i ka ʻoihana o ka hōkū paikikala Belgian ʻo Eddie Merkex ma ke ʻano ʻē a kupaianaha. ʻO ka mea ʻē loa, ua haku ʻia a hoʻonohonoho ʻia kēia mele e ka loea mele mua Pelekane ʻo David Munro, a ua hoʻokani ʻia e ka London Early Music Union, piha i ka ikaika. E noʻonoʻo i kahi palapala haʻuki e hōʻike ana i nā leo o ka hoʻokani ʻana i ka ʻohe, tromba marina ("violin a ka nun"), a me rauschpfeiffen i hele pū ʻia e ka poʻe me nā lole pōkole paʻa a me nā pālule ʻālohilohi e holo paikikala lahilahi ana ma nā puʻu o ʻEulopa.

I koʻu hoʻopili ʻana i nā Gold Badges i ka mea hoʻonui leo RAAL HSA-1b, ua lilo ke kani i mea paʻa a maopopo loa. Me HSA-1b, ʻo ke kahe a me ka ikaika o ka pepa mele e hoʻomalu nei i koʻu ʻike. ʻOi aku ka ikaika o ke mele. Ke ʻoi aku ka leo o ke mele, ʻoi aku ka manaʻo o ka hana a David Munrow.
Ke hoʻololi au mai ka pahu lāʻau Falcons i ka mea nānā pepeiao piha ākea SR1a a RAAL? Mai nā mea hoʻolele leo a i nā mea hoʻolele leo? Ua ʻike au i kahi "nānā" maopopo a ʻoi aku ka nānā ʻana o ka hoʻopaʻa leo.
He mea kū hoʻokahi ka transducer poʻo kila o RAAL ma ka mākeke pepeiao. He paʻa a kūpono hoʻi ke kumukūʻai ($3,500). Hoʻokomo ʻia ka lipine dipole o SR1a i loko o kahi pā kila kila ma kahi mamao loa mai ke poʻo. He mau lipine maoli lākou, a ʻo nā amplifiers a lākou e hōʻike nei he kokoke i ka piha o ka impedance ukana pōkole: 0.2 ohms, me nā kaula. Paipai ka manual mea hoʻohana i ka hoʻohana ʻana i ka mana amplifier 100W (footnote 1). Me ka lawa ʻana o ka wai amplifier, hāʻawi ʻo SR1a i nā pae leo i hoʻopaʻa ʻia, kala ʻole, haʻahaʻa-distortion e (manaʻoʻiʻo wau) ʻoi aku ma mua o ka super-resolution Stax SR-009S static a me kaʻu JPS Labs Abyss AB-1266 Phi TC a me HiFiMan Susvara planar magnetic element.

ʻO ka mea hoʻonui leo HSA-1b hou a HSA-1b RAAL (footnote 2) ka mea hoʻonui leo solid-state a me ka headphone mua aʻu i hoʻāʻo ai. I koʻu hoʻopili ʻana iā ia i kahi mea hoʻonui leo Stenheim Alumine Three e kū ana i ka papahele a lohe au hiki iā ia ke hoʻokele pono i ʻelua mau mea hoʻonui leo i kūʻai ʻia he US$32,900, ua ʻike au he ʻano mea hoʻonui leo ʻokoʻa ia mai ka mea hoʻonui leo Z10e/ Headphone a Linear Tube Audio 10Wpc (8 ohm), ua nānā hou au iā ia ma Gramophone Dreams #36 a i ʻole ʻo Ampsandsound's 8Wpc (8 ohm) Bigger Ben, a ua wehewehe au iā ia ma Gramophone Dreams #47.
ʻO ka HSA-1b a RAAL he mea hoʻonui leo liʻiliʻi ʻulaʻula ʻano knob he 11.7 paona me ka nui kūpono, 3.5" kiʻekiʻe x 8.6" laulā x 12.6" hohonu. Hoʻohana ia i ʻelua transistors hui bipolar (BJT) no kēlā me kēia kahawai, Hoʻopili ʻia nā bolts ʻelua i kahi radiator alumini hoʻokahi 8" × 3.5" × 2".
Kiʻekiʻe loa ke ʻano o ka hana ʻana a ma kona hihia, me he mea lā ua kūlike ka HSA-1b me nā kikoʻī koa. I ke ʻano, ʻo ke kiʻekiʻe o ke kūpono a me ka hoʻopau ʻana he koʻikoʻi ia o ka ikaika ʻoihana a me ka nani o ka hoʻonaninani home.
Ma waho aʻe o (a ma ka ʻaoʻao) o ke kumu mana IEC mandatory, ʻelua mau mea hoʻokomo pae laina ma ka panela hope o ka HSA-1b: kahi hoʻokahi-ended (RCA) a me kahi kaulike (XLR). Aia pū kekahi ʻelua mau pālua o nā jacks plug banana no ka hoʻopili ʻana i nā mea ʻōlelo stereo. Ma lalo o ka jack speaker, heluhelu ʻia "Serbian SAEQ i hoʻolālā ʻia a hana ʻia no nā koi RAAL".
Wahi a Aleksandar Radisavljevic, ke poʻo o nā mea pono āpau o RAAL, "ʻO SAEQ ke kū nei no nā lako leo Serbian. He hui ia o kahi hoaaloha maikaʻi loa aʻu i ʻike ai no 20 mau makahiki, ʻo Mr. Dragan Domanovich. Ua mahalo nui wau i kāna mea hoʻonui leo leo, i ka manawa a mākou Ma hope o ka hoʻopau ʻana i kāna mau headphone, ua nīnau au iā ia inā hiki iā ia ke hana i kahi mea hoʻonui no SR1a, kahi e hōʻailona ʻia he pono RAAL a hāʻawi wale ʻia ma ke ʻano he pono RAAL. Ua makemake nui ʻo ia e hana i nā hoʻololi e pono ai i ka topology o kāna mea hoʻonui punahele. Ma hope o hoʻokahi makahiki a ʻoi aku, ua loaʻa iā Dragan ke kani a mākou a pau ʻo Rr lāua ʻo SAEQ i makemake ai. I kēia manawa ua hiki iā SAEQ, ke hana nei lākou."
Aia ma ka panela mua o ka HSA-1b kahi kuapo mana ʻano leo ʻoihana 5/8" ke anawaena, i hoʻomālamalama ʻia e ke kukui ʻulaʻula. Ma kona ʻaoʻao ʻākau he mea hoʻohui puka headphone XLR ʻehā-pin, ʻo ia ke kāne ma mua o ka wahine maʻamau, No laila hiki ke hoʻopili ʻia nā pepeiao pepeiao SR1a lipine a RAAL; Loaʻa i ka pūʻolo HSA-1b kahi mea hoʻololi XLR wahine e hoʻololi ana i ke kāne i hiki i nā mea hoʻohana ke hoʻohui i ka 83dB/mW Susvara a HiFiMan a me nā pepeiao pepeiao ʻē aʻe e hoʻopau ana i ka mana, haʻahaʻa-naʻauao i HSA-1b. ʻO ka puka SR1a kiʻekiʻe-aupuni, ma ka ʻākau ʻo ia ka mea hoʻohui wahine ʻehā-pin o nā pepeiao pepeiao kaulike kuʻuna, a laila ka jack TRS 3.5mm (kaulike ʻole). Ma luna o ka mea hoʻohui pepeiao he lālani o ʻekolu mau kuapo no nā mea hoʻohana e koho ai ma waena o SR1a a me nā mea hoʻokele pepeiao kuʻuna. Ka puka SR1a, ka puka headphone a i ʻole ka mea ʻōlelo, ka hoʻokomo kaulike a kaulike ʻole. Ma ka ʻaoʻao ʻākau loa ʻo ia ka pihi leo hoʻomalu panela ʻulaʻula nui o HSA-1b, ka mea e hoʻomalu ana i kāna kaomi. kani, mea hoʻēmi 24-ʻanuʻu.
Ua haʻi mai ʻo Radisavljevic iaʻu ma kahi leka uila e hoʻohana ana ʻo HSA-1b i nā transistors hui bipolar no ka mea "he mau mea hana i hoʻokele ʻia e ke au, ʻaʻole nā mea hana i hoʻokele ʻia e ka voltage e like me MOSFET." No laila, "ʻoi aku ka kiʻekiʻe o nā pohō hoʻololi o BJT. Akā, he haʻahaʻa kona pohō conduction."
Ua haʻi aku au iā Radisavljevic i ka "drive kupaianaha" aʻu i lohe ai mai HSA-1b, ke hoʻokele nei ia i ka mea hoʻopuka leo Falcon LS3/5a 15 ohm, 83dB/2.83V/m??, kona mana a me ka maʻalahi kupaianaha. Ua noi au iā ia e wehewehe pehea e hana ai kāna mea hoʻonui "headphone" liʻiliʻi i kēia. Ua pane mai ʻo ia: "Aia ka mea hoʻokele ma laila, no ka mea hiki iā ia ke hāʻawi i 7 amps i kahi ukana 0.4 ohm, no laila he mea ʻole ka 15 ohms iā ia. He mea hoʻonui leo ia i hoʻomaikaʻi hou ʻia e hoʻokele i ka impedance haʻahaʻa. Ukana." Ma kahi leka uila ʻē aʻe, ua hoʻolauna ʻo Aleksander iaʻu i kekahi mau kikoʻī i helu ʻole ʻia ma ka pūnaewele pono e loaʻa iā RAAL: "ʻO ka loaʻa ma kahi o 10dB o ka hoʻokomo RCA. Me ka hoʻokomo XLR, inā loaʻa iā ʻoe kahi DAC puka kiʻekiʻe, hiki iā ʻoe ke koho e hōʻemi i ka loaʻa."
I loko o ka HSA-1b, aia kahi papa kaapuni paʻi liʻiliʻi e hoʻolōʻihi pololei ana mai ka papa hoʻokomo XLR me kahi kuapo DIP ʻeono kūlana, hiki ke hoʻohana ʻia no ka "hoʻoponopono ʻana i ka ʻike kūloko o ka hoʻokomo XLR". Wahi a ka manual kuhikuhi, he 3 mau koho a ka mea hoʻohana: 10dB, 6dB, 0dB. Ua hoʻonohonoho mua ʻia kaʻu hāmeʻa i 6dB.
"ʻO ka impedance puka o ka puka [headphone] kuʻuna he 5.3 ohms. ʻO ka mana mai kēia puka a i 32 ohms he 250mW, a ʻo ka mana mai kēia puka a i 300 ohms he 26mW. ʻO ka mana puka o ka puka SR-1a/Ribbon (drive dynamic a planar magnetic Headphones)) 1900mW ma 32 ohms a me 200mW ma 300 ohms." Inā pololei kaʻu makemakika, ʻo ia hoʻi ua hoʻonohonoho ʻia ke kuapo hoʻololi hema loa i ke kūlana i lalo a ʻo ka puka ribbon ma kahi o 7.75V.
HSA-1b Ma kahi ʻē aʻe o kēia puke, ke loiloi nei au i ka leo hoʻolele leo alumini ʻekolu noho papahele a Stenheim Suisse no $32,900/pālua. He ʻano pipiʻi loa kēia mau leo hoʻolele leo he 41-ʻīniha ke kiʻekiʻe i loko o nā keʻena alumini ʻulaʻula, ʻeleʻele a me ka hina. He ʻono a hou loa ko lākou helehelena. ʻO ka mea nui loa, hana hou lākou i nā hoʻopaʻa leo me ka maopopo ʻoi a ʻaʻole refraction, he mea hoihoi loa ia.
Ua ʻōlelo ka pūnaewele ʻo Stenheim ʻo ke koʻikoʻi o Alumine Three he 93dB/2.83V/m (footnote 3), a ʻo ka mana liʻiliʻi i ʻōlelo ʻia no ka amplifier he 10W. No laila, me ka hoʻohuli iki ʻana, ua hoʻāʻo wau e hoʻoikaika iā lākou me 10Wpc HSA-1b.
He mea paʻakikī iaʻu ke hoʻoholo inā e hoʻomaka i kaʻu hoʻokolohua RAAL-Stenheim me Champion Jack Dupree a i ʻole Jacqueline Du Pré. He wela a ʻūlū ia lā, a ua ʻala ka ea e like me ka iʻa, no laila ua hele au i ka Gutter Blues (16/44.1 FLAC Atlantic/Qobuz) me ke kiʻi hana noʻeau i hana ʻia e ka mea hoʻokani piano o New Orleans ʻo Jack Jerry Wexler i ka makahiki 1958. Ua kāhāhā au i ke ʻano ʻono o ke kani ʻana o ka piano a Dupree, a me ke ʻano momona a me ke ʻano maoli o ke kani ʻana o ka bass o Wendell Marshall mai nā woofers pālua 8" a Alumine Three.

Ua kākau maikaʻi loa ʻia, e like me nā manawa a pau! Ma ke ʻano he mea nona/mea hoihoi o Stax 9S, ke ʻae nei au e ʻoi aku ka paʻa o RAAL. I koʻu hoʻāʻo ʻana iā lākou, ua ʻike au he mea hoihoi lākou. ʻOiaʻiʻo, he mea hoihoi loa ia noʻu. Ua manaʻo wau ua kokoke koʻu mau pepeiao i kahi pahu snare a i ʻole saxophone. Akā no kekahi mau headphone premium (e like me Ferrari), he mea hoʻohui kupaianaha kēia. Mahalo!
E Mr. HR, he mea hoʻolaha a mea mahalo wau iā Stax. I ka hopena, ua kūʻai aku au i kaʻu Stax pilikino a ua hoʻōki loa i ke kūʻai aku iā Stax.
He mea maikaʻi paha kēia, akā, ʻeā? Malia paha he paʻakikī loa, he ʻoihana loa, he kū hoʻokahi loa, he paʻakikī loa. Malia paha ua like ia me ka Porsche 911 Turbo e kiʻi ana iā TacoBell ma Drive thru.
Ua like ke mele me ka launa pū ʻana me nā hoaaloha kahiko, ʻo Stax Music ua like ia me ka hoʻoponopono ʻana i nā pilikia me kaʻu mea loiloi.
Inā like kēia mau RAAL me Stax, hiki ke kūʻai lohi loa ʻia aku i ka hoʻohālikelike ʻia me nā lako e like me Diana of the Abyss. (Manaʻo wau)
Mahalo iā ʻoe no ka lawe ʻana mai i kēia hōʻike iā mākou, ʻaʻole hiki iaʻu ke noʻonoʻo e hiki iā lākou ke hilinaʻi i kekahi. (ʻO Tyll ka mea i hala koke aku nei) ʻOiai ʻaʻole i hoʻolaha ʻia, me he mea lā ʻo ʻoe mau ke pani o Tyll.
He mea hoʻohana headset STAX wau mai koʻu kūʻai ʻana i ka SR-5/SRD-6 i ka waena o nā makahiki 1970. Ua ukali ʻia e Lambda Pro/SRD-7 Pro a me kekahi mau set ʻē aʻe.
ʻO wai nā amplifiers āu e hoʻohana ai e hoʻokele i nā kelepona paʻalima STAX? Ua ʻike au he pilikia ko kekahi mau amplifiers solid-state i ka hoʻokele ʻana i ka ukana i hāʻawi ʻia e ka adapter STAX. I kēlā manawa, me he mea lā ua hana maikaʻi loa ʻo SAE 31B, a ua ʻike ʻia ʻo Hafler DH-200 i ka hopena o ke au.
Ua hauʻoli wau me nā Sennheisers waena (580/600/650 series) a me nā amplifiers Schiit Class A SS a me Schiit Valhalla 2 me nā paipu Lūkini (hoʻolele lākou i ke mele ma ke ʻano ʻoluʻolu a hoʻomaha). Ua lohe au i nā headphone hou a maikaʻi hoʻi, a i kēia manawa ke noʻonoʻo nei au iā ABYSS Diana, akā ʻaʻole wau wikiwiki. Ke hahai nei au a ke hoʻolālā nei i ka mana hou loa o Woo Firefly.
I koʻu wā kūʻai aku, ʻaneʻane ʻo Stax wale nō kaʻu headset. Loaʻa iaʻu kā lākou moʻo headset a me nā huahana uila e kūlike ana. Ma mua o RMAF i ka makahiki 2011, ua hālāwai au me Schiit Guys.
