Vuba aha, ubwo Marc Gomez, umuyobozi wa Suwede Analog Technologies (SAT, ibisobanuro birambuye kuri 1), yatangazaga ko hari imbunda ebyiri nshya zo gusimbuza imbunda ye ya mbere ya SAT, abasomyi bamwe bararakaye cyane cyangwa bishora mu kinyoma bati: “Kuki atabikoze neza rimwe? Igihe kirageze?”
Ibicuruzwa bigenda bihinduka uko igihe kigenda gihita hanyuma bigasohoka hakurikijwe gahunda runaka (imodoka, akenshi mu gihe cy'impeshyi) cyangwa iyo abakora ibikoresho by'ubugeni bibwira ko "biteguye" - amagambo ateye ubwoba kuko bamwe mu barota batigeze batekereza ko ari byo. Imiterere irateguwe bityo ntuzigere uyishyira ahagaragara ku mugaragaro, cyangwa ngo uyishyire ahagaragara nyuma ya V1, utange amanota ku bakiriya, aho kureka ibintu binonosorwa n'ivugurura bigakomeza kwiyongera uko igihe kigenda gihita hanyuma utange V2 nyuma y'umwaka umwe cyangwa ibiri.
Ku bijyanye na SAT, toni nasuzumye, nakunze, kandi naguze ntiyahise igaragara neza. Gomez yanyeretse isubiramo rya mbere muri High End i Munich, maze umwaka ushize yumva yiteguye kunyoherereza isuzuma. Nyuma y'uko igitekerezo gisohotse, mu nomero ya 1 yo muri Nyakanga 2015, natunguwe no kubona igitekerezo cyo mu 2013 kuri interineti kivuga kuri SAT igezweho cyane ikozwe muri fibre ya karubone, harimo na bearing bracket. (Icyitegererezo cyanjye cyari gifite bearing bracket ikozwe mu byuma bita steel stainless.) Icyo gihe, Gomez yakoraga SAT gusa, atari icyo nakwita uwakoze.
Ubwo narebaga ukuboko kwa SAT, byaguraga $28.000. Nubwo igiciro cyari kiri hejuru - cyakomeje kuzamuka uko igihe cyagiye gihita - Gomez yaje kugurisha intwaro za SAT zigera kuri 70 mbere yo guhagarika gukora. Ese ni "Tonearm nziza ku Isi?" nk'uko umutwe w'iyo nkingi ubyibaza? Ikibazo ni ingenzi: nzi nte ko ari "ikomeye"? Sinigeze numva abandi bahanganye, barimo Vertere Acoustics Reference na Acoustical Systems Axiom).
Nyuma y’uko isuzuma risohotse kandi ivumbi rigashira, nabonye ubutumwa bwinshi buturutse ku basomyi baguze ukuboko hashingiwe ku isuzuma ryanjye. Ibyishimo byabo n’ibyishimo byabo byari bihoraho - byarantunguye. Nta muguzi n’umwe wanyandikiye ubutumwa bwa email avuga ko yinubira SAT.
Gomez yize amasomo akomeye mu gihe cyo gukora ukuboko kwa mbere, harimo no kuba uko yakwipakira neza kose, uwakoherezaga yakoze ibishoboka byose kugira ngo aguce. Yahinduye imikorere ye mu gihe cyo gukora, harimo kunoza sisitemu yo kugabanya uburemere, no gupakira icyuma cyo hejuru gihagaze ukwacyo kugira ngo gishyirwe mu murima kugira ngo hirindwe kwangirika guterwa n'ingufu (nubwo Gomez ambwira ko ibi byabaye rimwe gusa). Ibi byoroshye kubivuga kuruta kubikora: bisaba agace gashya gafite ibice bibiri, n'igikoresho cyo gushyiramo neza icyuma gifata amapine mu murima.
Ariko yakomeje gukora izindi ntambwe igihe cyose, bityo mu mpera z'umwaka ushize Gomez yahagaritse gukora ukuboko kwa SAT kwa mbere maze agusimbuza amaboko abiri mashya, buri rimwe rifite uburebure bwa santimetero 9 na santimetero 12. Gomez, utari umupfumu (urugero: 2), afite impamyabumenyi y'icyiciro cya kabiri cya kaminuza mu ikoranabuhanga rya mekanike n'ubumenyi bw'ibikoresho, kandi ntiyigeze areka kuvuga ko, ibindi bintu bingana, ukuboko kwa santimetero 9 kwemerera ikaramu ya karito kwitwara neza, bitanga umusaruro mwiza. Bisa neza kurusha amaboko ya santimetero 12 (urugero: 3). Ariko, bamwe mu bakiriya bashaka amaboko ya santimetero 12, kandi mu bihe bimwe na bimwe (urugero: imitako y'inyuma ya turnet za Air Force), 12 gusa ukuboko kwa santimetero 1 ni byiza. Bite se? Hari umuntu waguze intwaro ebyiri za SAT koko? Yego.
Ubwoko bubiri (cyangwa bune) bushya ni LM-09 (na LM-12) na CF1-09 (na CF1-12) byagaragajwe hano. Ndanga gusobanura imbunda zigurishwa $25,400 (LM-09) cyangwa $29,000 (LM-12) nk'izihendutse, ariko ukurikije ko CF1-09 igurishwa $48,000, CF1-12 igurishwa $53,000 kandi ndabyishimiye. Wenda uri gutekereza uti: “Kuva ku gukora imbunda imwe ukagera kuri enye ni impinduka ikomeye ku sosiyete ikora umuntu umwe. Wenda Gomez arimo agura CF1 hejuru cyane ku buryo adakenera gukora nyinshi cyangwa zimwe muri zo.”
Sinakwiringira ibyo. Ndizera neza ko umuntu wese ushobora gukoresha $30.000 kuri toniarm ashobora no gukoresha $50.000 niba ikora neza cyane ndetse ikarushaho kuba nziza. (Ntimwandike amabaruwa "Hungry Baby"!)
Amaboko mashya ya SAT asa cyane na SAT ya mbere kuko asa cyane: ukuboko kwa mbere ubwako kwakozwe neza kandi kwakozwe neza. Mu by'ukuri, amaboko yombi mashya ya santimetero 9 ni yo asimbuza SAT ya mbere.
Mu gihe ategura sisitemu ikomeye yo gutwara ibintu idashobora kwangirika cyane mu gihe cyo gutwara ibintu, Gomez ananoza imikorere yayo binyuze mu kongera ubukana muri rusange no kugabanya ubwivumbure buhamye bw'icyuma gifata ibintu. Mu maboko yombi mashya, umugozi ushyigikira ibyuma bihagaze wabaye munini.
Amaboko mashya afite fibre ya karuboni ivuguruye, ishobora gukurwaho n'ibishishwa by'umutwe bya aluminiyumu - bitandukanye kuri buri kuboko - hamwe n'ubukonje bwinshi bwo gufatanya hamwe n'imikorere yoroshye yo kuzenguruka kugira ngo habeho azimuth isobanutse neza. Imiyoboro y'amaboko nayo ni mishya. Amaboko ya polymer y'imiyoboro y'amaboko ya mbere yarakuwemo, kandi fibre ya karuboni iri munsi iragaragara. Gomez ntiyasobanuye impamvu yabikoze, ariko wenda ni ukubera ko aho kuboko hashobora gusiga ibimenyetso bibi uko igihe kigenda gihita - cyangwa, birashoboka cyane, bigatuma ijwi rirushaho kuba ryiza. Uko byagenda kose, bizaha buri kuboko isura idasanzwe.
Ushobora gusoma byinshi ku bijyanye n'imiterere mishya y'intwaro kuri AnalogPlanet.com. Dore ibyo Gomez yambwiye muri imeri:
“Urwego rw’imikorere y’intwaro nshya ntabwo ari impanuka cyangwa ngo rube umusaruro w’akazi kakozwe kugira ngo kunoze imbaraga, ahubwo ni umusaruro w’ibikorwa byatekerejweho kandi bisaba imbaraga bihuza neza n’intego z’umwimerere zishingiye ku mbaraga.”
“Nongeye kandi, ndashaka gusobanura neza ko ntagabanya nkana imikorere y’icyitegererezo kimwe kugira ngo nshyire ku bandi kugira ngo bijyane n’igiciro/imikorere – ntabwo ari uburyo bwanjye bwo gukora, kandi kubikora byantera umubabaro. Ahubwo, ngerageza gushaka uburyo bwo kunoza imikorere y’icyitegererezo cyo hejuru. Muri iki gihe, CF1 series ifite igiciro cy’ikirenga mu bijyanye n’imikorere, umwihariko n’igiciro.
LM-09 ikorwa hakoreshejwe uburyo bushya bwo kubaka buhendutse, hamwe n'ibice byayo by'icyuma n'ibindi bice byayo bikozwe muri aluminiyumu, aho kuba icyuma kitagira umugese nk'uko byari bimeze mbere. Uburemere bugabanutse bugomba gutuma LM-09 irushaho kuba nziza ku maniko y'ibyuma.
Gupfunyika, kwerekana no gukwirana ni kimwe n'ukuboko kwa SAT kwa mbere. Ubuso bworoshye bwa aluminiyumu burashishikaje cyane.
Byatwaye iminota mike gusa kuyishyiramo no kumva aho bahinduranya amaboko kuri Continuum Caliburn turntable yanjye hanyuma bagasubiramo imiterere. Ariko, kura imashini irinda kuva kuri bearing yo hasi itambitse, mu gihe cyo kohereza, tandukanya umutwe wa bearing n'igikombe cyayo cya safiro hanyuma usimbuze igikombe cyo hejuru gisanzwe n'igikombe cyo hejuru gisanzwe, uyihambire ku mutwe hanyuma ushyireho preload, ni byiza ko umucuruzi abikora. Nabikoze, ariko ntibyari byoroshye cyane.
Nakoresheje Ortofon's MC Century Moving Coil Cartridge, nari narashyizeho kugira ngo isubirwemo mu nomero yo muri Nzeri 2018, kandi icyo gihe nari nzi neza iyo cartridge. Ariko mbere y'ibyo, numvise indirimbo y'umutwe wa Davy Spillane's Atlantic Bridge (LP, Tara 3019) maze nkora amajwi ya 24-bit/96kHz. Irimo Spillane kuri uilleann pipe na bass whistle, Béla Fleck kuri gitari acoustic na banjo, Jerry Douglas kuri Dobro, Eoghan O'Neill kuri fretless electric bass, na bodhran Christy Moore, n'abandi. Iyi alubumu yafashwe kandi ivanze neza muri Lansdowne Studios i Dublin, ifite bass nziza, yimbitse, icuranga neza, transients nziza ku mirya - banjos zafashwe neza - kandi hari byinshi bishimishije, byose bikwirakwijwe ku rubyiniro runini. Hari umuntu wagombye kongera kuyishyira ahagaragara!
Guhuza SAT na Ortofon MC Century bya mbere ni bimwe mu byakozwe neza cyane mu majwi yo mu 1987 nigeze numva, cyane cyane kubera imbaraga zayo zo mu bwoko bwa bass na control. Nashyizeho SAT LM-09 nshya maze nongera kuyicuranga no kuyifata amajwi.
Ndumva icyo ushaka kuvuga. Niba wabivuze mu bundi buryo: "inkuru nyinshi za kera za LP ziracyasa neza kurusha izindi nshya", ndabyemera cyane.
Yego, amatwi yanjye yangiritse ambwira ko imashini nyinshi za kera za LP zicyumvikana neza ugereranije n'izindi nshya.
Ndatekereza ko ari ikibazo kiri mu gufata amashusho ya master, ntabwo ari umuvuduko ubwawo. Mu bihe byashize, imiyoboro ya vacuum yari yo yonyine yari ikoreshwa mu by'ikoranabuhanga, none ubu hari ikoranabuhanga ryinshi rya digitale/solid-state rikoreshwa mu gufata amashusho ya mikoro/kuvanga/master.
Mu buryo bw'amajwi, nsanga izo LP za kera za stereo/mono classical music nkunda (zigera ku 1.000+) zumvikana neza kurusha izindi za kera (za 1960) mu bijyanye no gufunguka, ubushyuhe, no kuba koko. Nta na rimwe mu majwi yanjye arenga 30 y’ikoranabuhanga ry’ikoranabuhanga ryumvikana neza, nko kuba mu gasanduku, nubwo zose zumvikanaga neza, zisukuye, zishyushye kandi "zifite ishingiro" mu buryo bw’ikoranabuhanga.
Nkuko namaze kubishyira ku rubuga rwa Phono Forum hano, nacuranze bwa mbere indirimbo ya kera ya Colombian Masters LP ya Richard Tucker ubwo nacurangaga Orchestre ya Vienne State Opera yayobowe na Pierre Dervaux ku nshuro ya mbere: opera aria y'Abafaransa, naratunguwe cyane. (Mu myaka ya za 1960?) Mu by'ukuri nisanze nicaye hagati mu mirongo itatu ya mbere y'inzu ya oera (intebe nkunda cyane: imirongo 10-13 hagati). Igitaramo cyumvikana neza cyane, gifunguye, gifite imbaraga kandi gishishikaje. Wow! Nka Turner (ukomoka i Brooklyn, NY) uririmba hejuru yanjye kuri podium. Sinigeze ngira ibyishimo nk'ibi byo gucuranga imbonankubone mu rugo mbere.
Mu myaka ibarirwa muri za mirongo ntaragura rekodi ya vinyl, ariko ndacyagomba kuvuga ko imashini ishaje itarigeze iba nziza cyane. (Birumvikana ko hari ibidasanzwe, ari nayo mpamvu HP ishaje yakunze kwibanda ku buryo bworoshye kuri Vintage Living Presence).
Bwana Kasim asa nkaho yaguze imashini icapa ihari kandi arimo kuyubaka uko bishoboka kose. Agurisha inyandiko ze nshya za vinyl ku madolari 30 kugeza ku madolari 100 buri imwe.
Vinyl ubu ni ikintu gihenze cyane! (Koetsus yanjye yo mu myaka ya 1980 ntiyigeze ihendutse, mbere yagurishwaga $1,000).
Nakoresheje amatwi yanjye n'umutwe wanjye kugira ngo nishimire vinyl ntarinze kumena konti yanjye ya banki!
