I-LTA Z40 + iquka uDavid Burning onelungelo elilodwa lomenzi weZOTL amplifier kunye ne-51W amandla aphumayo angenakuguqulwa aveliswe ziipentode ezine kwiplate ephezulu yeyunithi.
Unokufunda konke malunga neZOTL, kubandakanywa ne-patent yokuqala ka-1997, kwiwebhusayithi ye-LTA.Ndiyikhankanya le nto kuba ayizizo zonke iintsuku ndiphonononga ii-amps ngeendlela zokukhulisa amalungelo abenzi, kwaye ngenxa yokuba ii-amps zeZOTL zikaDavid Burning ziye zaba ngundaba-mlonyeni ukusukela oko i-microZOTL yakhe yabetha izitrato ngo-2000.
I-LTA Z40+ idibanisa i-ZOTL40+ ye-Reference yamandla yokwandisa amandla enkampani kunye ne-Berning-designed preamp, kwaye bayalela i-Richmond, i-Virginia-based Fern & Roby ukuphuhlisa i-chassis.Ngokusekwe kubomi kunye nokusetyenziswa kwe-Z40 +, ndingathi benze izigqibo ezininzi ezikrelekrele - i-LTA Z40 + ayibukeki nje ukuba yinxalenye yemveliso eyenziwe kakuhle yomsindo, iyasebenza.
Iphakheji ye-Z40 + ye-tube yonke iquka i-2 x 12AU7, i-2 x 12AX7, i-2 x 12AU7 kwi-preamp kunye neebhanki ezine ze-Gold Lion KT77 okanye i-NOS EL34.Iyunithi yokuphonononga yafika kunye ne-NOS RCA / Mullard 6CA7 / EL34 izixhumi.Usenokuzibuza ukuba kutheni kungelula kangako ukufikelela kuzo zonke ezi zibane.Impendulo emfutshane kukuba i-LTA ilinganisela ubomi besibane kuluhlu lweeyure ze-10,000 (elide ixesha elide).
Isampuli yokuphonononga ibandakanya i-SUT op-amp ekhethiweyo esekelwe kwi-MM / MC phono yesiteji kunye ne-Lundahl amorphous core step-up transformer edibanisa iigalelo ezine ze-RCA ezingalinganiyo kunye nokufakwa kwe-XLR enye.Kukwakho iteyiphu ngaphakathi/ngaphandle kunye neseti yezibiyeli zeCardas zokuxhoma izithethi.Inguqulo entsha ye-"+" ye-Z40 yongeza i-100,000uF i-capacitor eyongezelelweyo, i-Audio Note resistors, i-subwoofer output, kunye nokulawulwa kwevolumu ehlaziyiweyo kunye nenzuzo eguquguqukayo kunye nezicwangciso "zesisombululo esiphezulu".Ezi seto, kunye nenzuzo kunye noseto lomthwalo weMM/MC izigaba zephono, zifikelelwa ngephaneli yangaphambili yenkqubo yemenyu yedijithali okanye i-Apple Remote ebandakanyiweyo.
Iqonga lephono lifanelwe ingqalelo kuba litsha ngokupheleleyo kwaye liphuculwe ngaphezu kweemodeli ezindala.Ukusuka kwi-LTA:
Izigaba zethu zephono ezakhelwe ngaphakathi zinokusetyenziswa kunye nemagnethi ehambayo okanye i-coil cartridges ehambayo.Iqukethe izigaba ezibini ezisebenzayo kunye ne-transformer yesinyathelo esongezelelweyo.
Uyilo lwaqala njengenxalenye kaDavid Burning's TF-12 preamplifier, eyathi yayilwa ngokutsha yaba yinto ehlangeneyo.Siyigcinile isekethe yohluzo lwe-equalization yasekuqaleni kwaye sikhethe i-IC ye-ultra-low yengxolo yenqanaba lokuzuza elisebenzayo.
Inqanaba lokuqala linenzuzo esisigxina kunye neenkqubo ze-RIAA, ngelixa inqanaba lesibini lineseto ezintathu ezikhethiweyo zokuzuza.Ukusebenza ngokufanelekileyo kweekhasethi zekhoyili ezihambayo, sinika iLundahl i-step-up transformers ene-amorphous core.Ziyakwazi ukulungelelaniswa ukubonelela nge-20 dB okanye i-26 dB inzuzo.
Kuhlobo lwamva nje lwesekethe, ukusetwa kwenzuzo, umthwalo ochasayo kunye nomthwalo we-capacitive unokuhlengahlengiswa ngemenyu yephaneli yangaphambili okanye ukude.
Izicwangciso zenzuzo kunye nomthwalo kwizigaba zangaphambili zephono zazisetwa kusetyenziswa iiswitshi ze-DIP ezinokuthi zifikeleleke kuphela ngokususa ipaneli yecala leyunithi, ngoko ke le nkqubo entsha eqhutywa yimenyu iyimpucuko enkulu malunga nokusebenziseka.
Ukuba ukhetha ukungayifundi le ncwadana ngaphambi kokuntywila kwi-Z40 + (ityala iwayini), unokumangaliswa (ndiye ndamangaliswa) ukufunda ukuba loo maqhosha obhedu awakho amaqhosha konke konke, kodwa ulawulo lokuthintela.OKULUNGILEYO Iperi yee-headphone jacks (Hi kunye ne-Lo) zikwabekwe kwiphaneli yangaphambili, iqhosha lokuguqula elibandakanyiweyo likhetha phakathi kwabo, kwaye iqhosha levolumu libonelela ngokuthomalalisa ngokupheleleyo kwe-128 dB kumanyathelo angama-100 okanye ukusebenza kokhetho "lweSigqibo esiPhezulu" kwiseto zemenyu., 199 amanyathelo olawulo oluchanekileyo.Inzuzo eyongeziweyo yendlela yeZOTL kukuba, ubuncinane kwimbono yam, ufumana i-51W i-amplifier edibeneyo enobunzima beepounds ze-18.
Ndidibanise i-Z40 + kwiibini ezine zezithethi - iDeVore Fidelity O / 96, iCredo EV.I-1202 Ref (ngaphezulu), i-Q Acoustics Concept 50 (ngaphezulu) kunye ne-GoldenEar Triton One.R (ngaphezulu).Ukuba uqhelene nezi zithethi, uya kwazi ukuba ziza kuluhlu olubanzi kuyilo, umthwalo (iimpedance kunye nobuntununtunu), kunye nexabiso ($2,999 to $19,995), okwenza iZ40+ ibe ngumsebenzi olungileyo.
Ndidlala iqonga le-phono le-Z40+ kunye ne-turntable ye-Michell Gyro SE exhotyiswe nge-TecnoArm 2 yenkampani kunye ne-CUSIS E MC cartridge.Ujongano lwedijithali luqukethe i-totaldac d1-tube DAC/streamer kunye ne-EMM Labs NS1 Streamer/DA2 V2 Reference Stereo DAC combo, ngelixa ndisebenzisa emangalisayo (ewe, ndathi eyoyikekayo) ThunderBird kunye neFireBird (RCA kunye neXLR) zidibanisa kunye noRobin. .Iintambo ze-hood yesithethi.Onke amacandelo anikwe amandla yi-AudioQuest Niagara 3000 unikezelo lwamandla.
Andithandi ukumangaliswa kule mihla, kodwa i-Q Acoustics Concept 50s (i-$ 2999 / isibini) iyamangalisa ngokwenene (uphononongo luyeza kungekudala) kwaye yenzela amava okuphulaphula ngokwenene (kakhulu) kunye neZ40 +.Nangona le ndibaniselwano iyinto engafaniyo yexabiso ngokwendlela yokwakhiwa kwenkqubo iyonke, oko kukuthi, ukunyuka kweendleko zesithethi, umculo ovelayo ubonisa ukuba kusoloko kukho okungafaniyo kuyo yonke imigaqo.I-bass ihloniphekile kwaye igcwele kakhulu, i-timbre ityebile kodwa ikhulile, kwaye umfanekiso wesandi unamandla, ucacile kwaye uyamema.Lilonke, i-Z40 +/Concept 50 indibaniselwano yenza ukumamela kulo naluphi na uhlobo olunomdla, olunomdla nokonwabisa kakhulu.Uloyiso, uloyiso, uloyiso.
Ngomngcipheko wokuziphikisa, i-GoldenEar Triton One.R Towers (i-7,498 yeedola kwisibini) ilungile nje ngomzalwana wabo omkhulu, i-Reference (uphononongo).Idityaniswe ne-LTA Z40 +, umculo uphantse ube mkhulu ngokuhlekisayo, kwaye imifanekiso ye-sonic idelela indawo kwaye idlulele kwizithethi.I-Triton One.R ibonisa i-subwoofer ene-self-powered, evumela i-amp ekhaphayo ukuba iphathe imithwalo elula, kwaye i-Z40 + yenza umsebenzi oncomekayo wokuhambisa i-core yomculo eyayisityebi ngokumangalisayo kunye nobuqili.Kwakhona, sawuqhawula umthetho wokuchitha imali eninzi kwizithethi, kodwa ukuba unokuva loo ndibaniselwano ngendlela endayiva ngayo eshedini, ndiqinisekile ukuba ungakunye nam ekujuleni le ncwadi yomthetho emgqomeni., ityebile, ifanelekile ngokupheleleyo kwaye imnandi.kuhle!
Ndijonge phambili kule combo, i-O/96 kunye ne-Z40 +, kuba ndiyazi i-DeVore ngcono kunoninzi.Kodwa emva kwemizuzu embalwa ndaxelelwa ukuba le ndibaniselwano yayikude kakhulu.Ingxaki ephambili kukuveliswa kwe-bass okanye ukungabikho kwayo, kwaye umculo uvakala ukhululekile, ungekho kwindawo kwaye kunokuba unqabile, ongaqhelekanga kwezinye izixhobo.
Ndibe nethuba lokuva i-LTA ZOTL Ultralinear + amp edityaniswe nezithethi ze-DeVore Super Nine e-Axpona 2022 kunye nokucula kunye nokungxola kwendibaniselwano yenze ukuba ibe kuluhlu lwam lwemiboniso endiyithandayo.Ndicinga ukuba umthwalo okhethekileyo we-O / 96 awufanelekanga kwi-ZOTL amplifier.
I-Credo EV 1202 Art.(Amaxabiso aqala kwi-16,995 yeedola) zii-headsets ze-Ultra-thin tower ezenza ngaphezu kokuba zijongeka, kwaye i-Z40 + ibonisa icala layo lomculo kwakhona.Njengakwizithethi ze-Q Acoustics kunye neGoldenEar, umculo wawutyebile, ukhulile kwaye ugcwele, kwaye kuzo zonke iimeko izithethi zazibonakala zihambisa into ekhethekileyo kunye nesandi esikhulu seZ40 + esinamandla.IiCredos zinamandla angaqhelekanga okunyamalala, kwaye ngelixa zivakala zikhulu kakhulu kunobukhulu bazo, oko kunokuthetha ukwenza amava omculo apho ixesha linyamalala kwaye lithatyathelwa indawo ziintshukumo kunye namaxesha aqulethwe kurekhodisho.
Ndiyathemba ukuba olu khenketho lwezithethi ezahlukeneyo luya kukunika umbono weZ40 +.Ukongeza ukugqiba ukugqiba imiphetho, iamplifier ye-LTA ibonelela ngolawulo olugqwesileyo oludityaniswe nesandi esityebileyo setoni kunye nomfanekiso we-sonic owandisiweyo onobuqili kunye nobandakanyayo.Ngaphandle kweDevor.
