I-LTA Z40+ ifaka isikhulisi se-ZOTL esinelungelo lobunikazi sikaDavid Burning esinamandla okukhipha i-transformerless angu-51W akhiqizwe ama-pentode amane epuleti eliphezulu leyunithi.
Ungafunda konke nge-ZOTL, okuhlanganisa ne-patent yango-1997, kuwebhusayithi ye-LTA.Ngikusho lokhu ngoba akuzona zonke izinsuku lapho ngibuyekeza ama-amps anezindlela zokukhulisa ezinelungelo lobunikazi, futhi ngenxa yokuthi ama-amps eZOTL kaDavid Burning abe ngundabamlonyeni kusukela i-microZOTL yakhe yaqala ukuvela emigwaqweni ngo-2000.
I-LTA Z40+ ihlanganisa isikhulisi samandla senkampani i-ZOTL40+ Reference ne-preamp eyakhelwe u-Berning, futhi bagunyaze i-Richmond, i-Fern & Roby esezinze eVirginia ukuthi yakhe i-chassis.Ngokusekelwe empilweni nasekusetshenzisweni kwe-Z40+, ngingasho ukuthi benze izinqumo eziningi ezihlakaniphile - i-LTA Z40+ ayibukeki nje kuphela njengengxenye yokukhiqizwa komsindo okwenziwe kahle, iyasebenza.
Iphakethe le-All-tube Z40+ lihlanganisa 2 x 12AU7, 2 x 12AX7, 2 x 12AU7 ku-preamp namabhange amane e-Gold Lion KT77 noma i-NOS EL34.Iyunithi yokubuyekeza ifike nezixhumi ze-NOS RCA/Mullard 6CA7/EL34.Ungase uzibuze ukuthi kungani kungelula kangaka ukufinyelela zonke lezi zibani.Impendulo emfushane ukuthi i-LTA ikala impilo yesibani ebangeni lamahora ayi-10,000 (okuyisikhathi eside).
Isampula yokubuyekeza ifaka phakathi isiteji sephono se-SUT op-amp esisekelwe ku-MM/MC esine-Lundahl amorphous core step-up transformer exhuma okokufaka kwe-RCA okune okungakalingani kanye nokokufaka okukodwa kwe-XLR.Kukhona nekhasethi yokungena/ngaphandle kanye nesethi yabakaki be-Cardas bepheya yezipikha.Inguqulo entsha ethi “+” ye-Z40 yengeza i-capacitor engu-100,000uF eyengeziwe, izimelaphi ze-Audio Note, i-subwoofer ephumayo, nokulawulwa kwevolumu okubuyekeziwe okunenzuzo eguquguqukayo kanye nezilungiselelo “zokucaca okuphezulu”.Lezi zilungiselelo, kanye nezilungiselelo zokuzuza nokulayisha zezigaba zephono ze-MM/MC, zifinyelelwa ngohlelo lwemenyu yedijithali yephaneli yangaphambili noma nge-Apple Remote efakiwe.
Isiteji sephono sifanelwe ukunakwa ngoba sisha ngokuphelele futhi sithuthukisiwe ngaphezu kwamamodeli amadala.Kusuka ku-LTA:
Izigaba zethu zephono ezakhelwe ngaphakathi zingasetshenziswa ngozibuthe onyakazayo noma ama-coil cartridges anyakazayo.Iqukethe izigaba ezimbili ezisebenzayo kanye ne-transformer eyengeziwe yesinyathelo-up.
Idizayini yaqala njengengxenye ye-preamplifier ka-David Burning's TF-12, eyahlelwa kabusha yaba into ehlangene yefomu.Sigcine isifunda sesihlungi sokulinganisa sangempela futhi sakhetha i-IC yomsindo ophansi kakhulu wesigaba sokuzuza esisebenzayo.
Isigaba sokuqala sinenzuzo engaguquki futhi sicubungula ijika le-RIAA, kuyilapho isigaba sesibili sinezilungiselelo ezintathu zokuzuza ezikhethwayo.Ukuze usebenze kahle kakhulu kwamakhasethi ekhoyili anyakazayo, sinikeza ama-Lundahl ama-step-up transformers ane-amorphous core.Angalungiswa ukuze anikeze inzuzo engu-20 dB noma engu-26 dB.
Enguqulweni yakamuva yesekhethi, isilungiselelo senzuzo, umthwalo ophikisayo nomthwalo we-capacitive kungalungiswa ngemenyu yephaneli yangaphambili noma ukude.
Izilungiselelo zokuzuza nokulayisha ezigabeni zephono zangaphambilini zazisethwe kusetshenziswa amaswishi e-DIP ayengafinyelelwa kuphela ngokukhipha iphaneli eseceleni yeyunithi, ngakho lolu hlelo olusha oluqhutshwa yimenyu luyintuthuko enkulu mayelana nokusebenziseka.
Uma ukhetha ukungafundi imanuwali ngaphambi kokungena ku-Z40+ (iwayini eligxekayo), ungase umangale (ngamangala) ukuthola ukuthi lezo zinkinobho zethusi azizona izinkinobho nhlobo, kodwa izilawuli zokuthinta.KUHLE Ipheya lamajekhi e-headphone (u-Hi no-Lo) nawo atholakala kuphaneli yangaphambili, i-toggle switch efakiwe ikhetha phakathi kwawo, futhi i-knob yevolumu inikeza ukuncishiswa okugcwele kwe-128 dB ezinyathelweni eziyi-100 ngazinye noma kusebenze izinketho "Zokulungiswa Okuphezulu" kuzilungiselelo zemenyu., izinyathelo ezingu-199 zokulawula okunembe kakhudlwana.Inzuzo eyengeziwe yendlela ye-ZOTL yukuthi, okungenani ngokombono wami, uthola i-amplifier ehlanganisiwe engu-51W enesisindo esingamakhilogremu angu-18.
Ngixhume i-Z40+ kumapheya amane ezipikha - i-DeVore Fidelity O/96, i-Credo EV.1202 Ref (okwengeziwe), Q Acoustics Concept 50 (ngaphezulu) kanye ne-GoldenEar Triton One.R (ngaphezulu).Uma ujwayelene nalezi zikhulumi, uzokwazi ukuthi ziza ngemiklamo ehlukahlukene, umthwalo (i-impedance kanye nokuzwela), kanye nentengo ($2,999 to $19,995), okwenza i-Z40+ ibe ukujima okuhle.
Ngidlala isiteji sephono se-Z40+ nge-turntable ye-Michell Gyro SE efakwe i-TecnoArm 2 yenkampani kanye ne-CUSIS E MC cartridge.I-interface yedijithali iqukethe i-totaldac d1-tube DAC/streamer kanye ne-EMM Labs NS1 Streamer/DA2 V2 Reference Stereo DAC combo, kuyilapho ngisebenzisa inhlanganisela emangalisayo (yebo, ngithe awesome) iThunderBird neFireBird (RCA ne-XLR) kanye noRobin. .Izintambo zesipika sehood.Zonke izingxenye zinikwa amandla amandla kagesi we-AudioQuest Niagara 3000.
Angijwayele ukumangala kulezi zinsuku, kodwa i-Q Acoustics Concept 50s ($2999/pair) iyamangalisa ngempela (isibuyekezo siyeza maduze) futhi yenzela umuzwa wokulalela ogxilile ngempela (kakhulu) nge-Z40+.Nakuba lokhu kuhlanganiswa kuwukungafani kwentengo ngokwendlela yokwakha isistimu iyonke, okungukuthi ukwandisa izindleko zesipikha, umculo ovelayo ubonisa ukuthi kuhlale kukhona okuhlukile kuyo yonke imithetho.I-bass ihloniphekile futhi igcwele kakhulu, i-timbre inothile kodwa ayivuthiwe, futhi isithombe somsindo siyagqama, sisobala futhi siyamema.Sekukonke, inhlanganisela ye-Z40+/Concept 50 yenza ukulalela noma yiluphi uhlobo kujabulise, kujabulise futhi kujabulise kakhulu.Ukunqoba, ukunqoba, ukunqoba.
Engozini yokuziphikisa, i-GoldenEar Triton One.R Towers ($7,498 ngepheya) mihle njengomfowabo omkhulu, i-Reference (isibuyekezo).Kuhlanganiswe ne-LTA Z40+, umculo ucishe ube mkhulu ngokuhlekisayo, futhi izithombe ze-sonic zidelela isikhala futhi zeqe izipikha.I-Triton One.R ifaka i-subwoofer ezishayelayo, evumela i-amp ehambisana nayo ukuthi iphathe imithwalo elula, futhi i-Z40+ yenze umsebenzi omuhle kakhulu wokuletha umongo womculo owawucebile ngokumangalisayo futhi ucashile.Nakulokhu futhi, sephule umthetho wokusebenzisa imali eningi ezipikheni, kodwa uma ungazwa leyo nhlanganisela ngendlela engiyizwe ngayo eshede, ngiyaqiniseka ukuthi ungahlanganyela nami ekulahleni incwadi yomthetho kudoti., ecebile, egcwele futhi ejabulisayo.kuhle!
Ngiyibheke ngabomvu le combo, i-O/96 ne-Z40+, ngoba ngimazi kangcono i-DeVore kuneningi.Kodwa ngemva kwemizuzu embalwa ngatshelwa ukuthi le nhlanganisela yayikude kakhulu.Inkinga enkulu ukukhiqizwa kabusha kwe-bass noma ukuntuleka kwayo, futhi umculo uzwakala ukhululekile, ungekho endaweni futhi kunalokho ugqamile, okungajwayelekile kwamanye amadivaysi.
Ngibe nethuba lokuzwa i-LTA ZOTL Ultralinear+ amp ebhangqwe nezipikha ze-DeVore Super Nine e-Axpona 2022 futhi ukucula nokuphakama kwenhlanganisela kukwenze kwaba sohlwini lwami lwemidlalo eyintandokazi.Ngicabanga ukuthi umthwalo othize we-O/96 awufanele i-ZOTL amplifier.
I-Credo EV 1202 Art.(Amanani aqala ku-$16,995 ipheya) angamahedfoni ombhoshongo azacile kakhulu enza ngaphezu kokubukeka kwawo, futhi i-Z40+ iphinda iveze uhlangothi lwayo lomculo.Njengezipikha ze-Q Acoustics kanye ne-GoldenEar, umculo ubucebile, uvuthiwe futhi ugcwele, futhi kuzo zonke izimo izipikha zibonakala ziletha okuthile okukhethekile ngomsindo omkhulu nonamandla we-Z40+.Ama-Credo anekhono elingajwayelekile lokunyamalala, futhi ngenkathi ezwakala emakhulu kakhulu kunosayizi wawo, kungasho ukudala okuhlangenwe nakho komculo lapho isikhathi sinyamalala futhi sithathelwa indawo ukunyakaza nezikhathi eziqukethwe ekurekhodweni.
