Lub hlis no, kuv yuav tsav tsheb ob peb mais hauv Ford odometer tshuaj xyuas qhov cuam tshuam ntawm Ron Sutherland cov khoom siv tam sim no tam sim no: $ 3,800 transimpedance dynamic preamplifier hu ua SUTZ.Nyob rau hauv txoj kev, kuv tseem yuav rov qab mus rau $ 1250 Dynavector DV-20X2 dynamic cartridge thiab tshawb nrhiav dab tsi yuav yog qhov zoo tshaj plaws hauv Dynavector cartridge kab: $ 2150 XX-2 MKII.
Thaum kawg, kuv yuav so, tawm ntawm lub tsheb, thiab rov ua kom kuv tus kheej nrog Lounge Audio's $ 355 Copla preamp, uas kuv tau siv txaus siab txij li kev tshuaj xyuas thaum Lub Ob Hlis 2018, tab sis tsis tau sau txog txij li kev tshuaj xyuas.
Sutherland Engineering SUTZ Kuv tau siv sijhawm ntau los sim xav txog txhua lub suab nrov electromagnetic tshwm sim los ntawm lub viav vias ntawm tus pas txuas nrog qee yam coil hauv qhov chaw sib nqus.Kuv xav txog cov ntaub ntawv cov kab nrib pleb dangling los ntawm ib rab koob me me / cantilever / coil sib dhos, ncab cov hlau nro thiab co coil los ntawm cov kab ruaj khov ntawm lub zog tsim los ntawm cov hlau nplaum me me.Raws li cov coils dhau los ntawm qhov sib nqus flux ntawm cov hlau nplaum, ib qho tam sim no raug ntxias raws lawv qhov ntev.
Kuv kawm kos ib feem ntawm Faraday txoj cai hauv tsev kawm theem qis.Hauv tsev kawm ntawv theem siab, tus kws qhia ntawv tau piav qhia Lenz txoj cai, uas yog qhov nyuaj rau kev nkag siab: "Lub polarity ntawm qhov hluav taws xob los ntawm kev hloov pauv hauv cov hlau nplaum tsim ib qho tam sim no uas nws cov hlau nplaum sib txawv ntawm qhov kev hloov pauv uas ua rau nws."
Kuj ceeb tias, Lenz txoj cai thiab nws qhov kev sib nqus sib nqus tau los rau hauv kuv lub siab thaum kuv tab tom sim xav txog yuav ua li cas tam sim no cov suab tswj theem yuav ua haujlwm thiab vim li cas lawv thiaj li cuam tshuam rau lub suab ntawm lub cassette li no.Qhov kev nco qab no tau coj kuv los qhia tias kev thauj khoom lub thawv txav txav nrog lub voj voog luv luv (tsis muaj qhov hluav taws xob input) ua kom lub zog tam sim no ntws los ntawm cov cartridge coil, uas ua rau Lenz txoj cai thim rov qab, yog li damping kom ua tiav qhov siab tshaj plaws ntawm kev txav mus los. cantilever coil (cov lus hauv qab 1).
Kuv mam li sim xav txog yuav ua li cas tam sim no damping piv rau damping muab los ntawm ib txwm shunt resistor nyob rau hauv pem hauv ntej ntawm lub active theem.Kuv yeej ib txwm xav tias txhua qhov sib txawv ntawm kev thauj khoom / damping cuam tshuam zoo npaum li cas cov stylus taug qab cov grooves ntawm cov ntaub ntawv, thiab kuv tau los txog qhov xaus tias qhov sib txawv ntawm damping (txawm lawv yuav ua li cas) yog lub luag haujlwm rau qhov sib txawv hauv kev taug qab, zawj. suab nrov, visceral hnov Causal cov ntsiab lus thiab intermodulation distortion.
Txog tam sim no, kuv tau them ib pawg ntawm cov theem sib luag-loaded phono theem, ntau yam kev hloov pauv hloov pauv, thiab peb theem "transimpedance" phono theem: Lounge Audio's Copla rau $ 355, Dynavector's P75 MK3 phono theem rau $ 895, thiab Sutherland Engineering's Little Loco rau $3,800.
Keeb kwm, kuv saj hauv phonograph playback tau nyiam high-nickel step-up transformers uas sim ua kom pom cov cua thiab filaments ntawm RIAA raj EQs.Tsis ntev los no, txawm li cas los xij, kuv tau ua haujlwm nyob rau theem qis, cov ntaub ntawv siab ceev los ntawm Sutherland Engineering Little Loco tam sim no-tswj phono theem Kuv tau siv nrog My Sonic Lab qhov tso zis qis (0.3mV), qis impedance (0.6 ohm) Ultra Eminent EX dynamic cartridge.Little Loco zoo li txhim kho txhua yam me me ntawm daim cartridge no muab rau nws.Piv rau lub suab ntawm Eminent EX nyob rau theem ntawm Parasound Halo JC 3+ phono theem, My Sonic-Loco combo tau ua si loj dua (raws li cov duab thiab suab chaw) thiab sleeker (raws li kev ntxhib los mos thiab nplai) - nrog ib abyss qab.Cov no yog cov ntawv uas ntsiag to.
Yog li mam li nco dheev kuv daig: yuav ua li cas kuv thiaj li tau txais tag nrho cov luv luv-circuit silence thiab grain-dawb microdata yam tsis raug yuam kom tso tseg CinemaScope thiab RIAA lub raj theem tshuab?
Kuv tau piav qhia qhov teeb meem no rau kuv tus phooj ywg Chad Stelly, uas tau coj qhov teeb meem no rau peb tus phooj ywg Ron Sutherland ntawm Sutherland Engineering (cov lus hauv qab 2);Ron tam sim ntawd teb, "Kuv daws tau nws!"Ib lub lim tiam tom qab, kuv tau koom nrog.Ron qhov kev tsim tawm tshiab tshaj plaws, "SUTZ" transimpedance preamplifier, mus rau 47 kΩ txav cov hlau nplaum tawm ntawm kuv Tavish Design Adagio tag nrho cov raj phono theem.
SUTZ preamp los ntawm Sutherland Engineering siv tib yam 17 x 2 x 13 "chassis raws li Little Loco preamp Kuv tau piav qhia hauv kuv lub Ib Hlis 2022 stereophile.Qhov tseeb, SUTZ zoo nkaus li zoo li Little Loco sab hauv thiab sab nraud.tib yam peb jumper-activated nce nqis li Little Loco.Thaum kuv nug tias qhov nce SUTZ muaj dab tsi, Ron tau xa email rau kuv tias tag nrho cov SUTZ yav tom ntej yuav muaj tsib qhov nce ntxiv, tab sis tsuas yog cem kuv.Lub transimpedance amplifier tsis muaj "nce" vim hais tias cov input units (amps) tsis phim cov zis units (volts).“(cov lus hauv qab 3)
Ua ntej kuv pib, kuv yuav tsum hais tias pawg ntawm cov khoom uas kuv siv yog qhov kuv hu ua tag nrho cov raj "real-fi" system: lub phono cartridge thiab cov kauj ruam-up transformer txuas nrog 10.5 "Thomas caj npab.Schick Dr. Feickert Blackbird teb EQ, Tavish Tsim Adagio phono theem lossis SunValley SV EQ1616D phono theem, Lab 12 Pre 1 kab theem preamp txuas nrog Elekit TU-8600S SE amplifier (nrog Western Electric 300B leeg), rau Falcon Kub.Thaum lub sij hawm auditions no, kuv tau nco ntsoov ntau npaum li cas kuv hlub no system thiab yuav ua li cas nws kaw nrog cov suab muaj tseeb thiab ntau tiag tiag recordings tshaj txhua qhov system kuv tau tsim txij li thaum kuv pib sau ntawv rau Stereophile.
Dynavector DV-20X2 Txij li thaum kuv tau tshuaj xyuas nws hauv Gramophone Npau suav #10, tsis muaj lub cassette hauv kuv chav tau ua si discs ntau dua li $ 1,250 Dynavector DV-20X2 dynamic player.Kuv tau siv ntau pua teev ua si ntawm yam tsawg kawg kaum kaum turntables.Nws plays txoj kev uas kuv nyiam turntable cartridges: crisp, ceev, thiab insightful.Nws muaj mojo-vivo txaus los ua kom muaj zog kaw nrog cov kev hloov pauv thiab kev txhaj tshuaj, tag nrho thaum so kom txaus.Ntawm no tus nqi taw tes, ob peb cartridges tuaj yeem ua ob qho tib si.Ntau tus neeg ua tsis tau.
Txawm tias tag nrho cov sij hawm siv, 20X2 tseem tswj kom tsis muaj zog tsim cov suab paj nruag tawg tsis tau so, ua siab ncaj rov tsim dua ib qho ntawm qhov zoo tshaj plaws thiab nrov tshaj plaws recordings los ntawm field engineer David Lewiston: Golden Rain LP "Ketjak: Ramayana Monkey Chant" (LP Nonesuch Explorer ).H72028).Cov kev hloov pauv muaj zog ntawm 200 tus txiv plig hu nkauj hauv ib leeg yog qhov zoo heev, txawm tias kuv paub tias lawv tab tom yuav tawg rau hauv kev quaj ntawm 'tak'.Cov hauj sam nyob rau hauv lub tshav puam yog teem nyob rau hauv concentric voj voog, uas yog to taub nyob rau hauv ib nrais muag.Nyob rau hauv cov nqe lus nyob ntsiag to, kuv lub siab lub qhov muag nyiam taw qhia qhov chaw ntawm ib tug neeg pe hawm Vajtswv hu nkauj ntawm qhov kawg ntawm cov voj voog no.Thaum cov hauj sam nres qw, lub suab ambient nyob rau hauv lub tshav puam ua rau kuv pom thiab hnov lawv nyob.Cartridges nrog rau qib kev pom no tsis tshua muaj nyob rau qib no.
Txhua zaus kuv ua si "Monkey Chant" nrog Dynavector 20X2 MC, Sutherland SUTZ, thiab SunValley SV EQ1616D tag nrho-tube phono theem, kuv xav tsis thoob thiab dazzled los ntawm pristine clarity, xob laim ceev, thiab dynamics tsis muaj hesitation.transients coj qhov chaw nrog cov suab sib txawv thiab ntse nrog pom qhov sib txawv ntawm tus neeg hu nkauj lub suab.Rau kuv, qhov no yog hom tshiab wow!Lub Sij Hawm: Cov ntaub ntawv disk tam sim no tau kho kom zoo nkauj los ntawm SunValley hlab.
Dynavector XX-2 MKII Chad Stelly zoo siab nrog kuv hauv cov ntawv nyeem txog "kev sib koom ua ke zoo kawg" ntawm Dynavector XX-2 MKII dynamics nrog Sutherland SUTZ, yog li kuv tau hu rau Mike ntawm Toffco, Dynavector's US distributor, Prank (footnote 4), leej twg lees paub. Chad qhov kev soj ntsuam tias $ 2,150 XX-2 MKII yog zaum "kub" hauv Dynavector cartridge kab.Nov yog lub sijhawm zoo siab tshaj plaws rau Dynavector.
Kuv tseem nyiam Dynavector cartridges vim tias lawv thov tias lawv tsom mus rau engineering program ntawm qhov tseem ceeb ntawm qhov teeb meem: kev tsim hluav taws xob sib nqus.Lawv lub vev xaib piav qhia: "Peb cov kev suav thiab kev sim tau pom tias txawm tias qhov hloov pauv me me hauv flux tuaj yeem ua rau muaj kev hloov pauv hauv cov hlau nplaum hauv qhov sib txawv ntawm huab cua, yog li cuam tshuam rau qhov cuam tshuam ntawm kev cuam tshuam ntawm cov teeb liab tso tawm."5 hlau nplaum es tsis txhob samarium-cobalt los yog neodymium-boron.Lub hom phiaj ntawm Dynavector's patented "flux damping" thiab "mos magnetic field" yog kom txo qis "tsis xav tau kev sib nqus sib nqus".
Raws li lub vev xaib Dynavector, XX-2 MKII siv Alnico 5 cov hlau nplaum (cov lus hauv qab 5) vim tias lawv muaj cov hlau nplaum sib nqus siab uas, piv rau lwm hom hlau nplaum, "ua kom muaj qhov sib nqus ruaj khov dua thiab yog li khaws cov khoom ruaj khov dua. voltage"..
XX-2 MKII muaj qhov tsis zoo (6 ohm) sab hauv thiab cov zis hluav taws xob tsawg ntawm 0.28 mV.Nws lub cev muaj zog nyob hauv rugged 7075 txhuas vaj tse thiab cov cartridge hnyav 9.2 grams.Kev ua raws cai yog teev nyob rau ntawm 10 µm / mN thiab Dynavector pom zoo kom tsis muaj load (30 ohms).
Lub 20X2 siv qhov qhib MicroRidge stylus ntawm lub raj dural cantilever, thaum lub XX-2, qhov pheej yig tshaj cartridge nyob rau hauv Dynavector kab, siv ib tug nyuaj boron cantilever nrog ib tug Pathfinder stylus nrog ib tug 7 × 30 µm kab sib cuag ntawm lub ntsis.Kuv Yog tias kuv nco qab raug, qhov no yog tib lub pob zeb diamond Ogura uas Lyra thiab Koetsu siv.
Cov lus hauv qab 3: Technically txiav txim siab qhov nce ntawm lub transimpedance phono theem tsis yooj yim: nws yog tib yam li niaj zaus, qhov piv ntawm cov zis voltage rau input voltage los yog tso zis tam sim no rau input tam sim no - xaiv ib tug ntawm lawv.Tab sis qhov ntawd tsis yog qhov txaus siab rau qhov tam sim no-input phono theem, uas nws txoj hauj lwm yog los hloov tam sim no rau hauv voltage.Rau cov cuab yeej zoo li no, kev hloov pauv hloov pauv hloov pauv yog qhov tsis tuaj yeem, uas yog vim li cas Ron Sutherland txiav txim siab hu rau cov khoom no SUTZ: nws tuaj yeem suav hais tias yog hom tshiab ntawm kev hloov pauv hloov pauv, txawm tias nws tsis yog qhov hloov pauv li niaj zaus. kev xav.Vim li cas Z thaum kawg?Tej zaum vim tias txoj hauv kev los ua tus yam ntxwv ntawm cov khoom siv transimpedance yog qhov piv ntawm cov zis hluav taws xob rau cov khoom siv tam sim no, uas muaj cov ntsuas impedance, feem ntau txhais los ntawm tsab ntawv Z. - Jim Austin Jun 30 '11 ntawm 12: 01
