Zimatithandizira, popeza tikusowa zigawo ziwiri zokha: imodzi ya phono preamp kuchokera ku sewero lolemba ndi china china chirichonse cha USB DAC chikuchitika kuti chigwiritsidwe ntchito sabata.
Chokhachokha pansi pa phukusi lonse chinali chakuti mbale yapansi yomwe inkaphimba oyendayenda inatsekedwa mmwamba, monga iyo inachotsedwa pa unit yomwe inabwera kukonza. Tinakokera mbale yapansi kuti tipeze bolodi ladongosolo losindikizidwa. Tinawona miphika inayi yokonza mitengo kuti ikhale yosakaniza zikhomo, koma palibe olemba mayina omwe amayesa kuyesa. Ndipo, ndithudi, bukuli silikuunikira makamaka.
Kuchokera ku mayesero omwe tinakwanitsa kuchita, tapeza kuti zida zogwiritsira ntchito mitsempha zinali zopitirira 15 W kupatulapo Z -84 zapamwamba zoposa 12 W. Izi zikhoza kukhala chinthu chofunikira kwa iwo amene akufuna ma tubes oyenera bwino nthawi yaitali ndikuchita bwino pakapita nthawi. Kumbukirani kuti kuchita zimenezi ndi njira yeniyeni komanso kungayika zala zazing'ono pafupi ndi magetsi mazana angapo. Kotero samalani.

Mengyue Mini: Kuchita
Tinafananitsa Mini Mengyue ndi amphamvu a Krell S-300i, omwe amawerengedwa mosamala pa 150 W pa kanjira mpaka 8 ohms. Miyeso inagwirizanitsidwa, okamba nkhani a Revel anali ogwirizana, ndipo Firestone ILTW USB DAC yowunikira maimpi onse awiri. Tinasankha kumvetsera mwatcheru kumvetsera mokweza kuti tiweruzire khalidwe labwino, koma osati mokweza kotero kuti kawirikawiri amakhoma msonkho wotsika wa Mengyue.
Imodzi mwa nyimbo zathu zoyesa nthawi zonse , zomwe Holly Cole analemba za "Phunzitsani Nyimbo," adatiuza zambiri zokhudza Mengyue Mini. Palibe zojambula zomveka zooneka bwino kapena zolakwika, ndipo Mini imatha kuthana ndi zolemba zazikulu, zopanda mphamvu popanda kumvetsetsa. Liwu la Cole limamveka bwino komanso lokongola. Kulumikizana kwa dzanja kumene kumapangitsa nyimboyi ikupezeka mokwanira, ndipo mabasi ali ndi mafuta abwino, abwino kwambiri.
Titasintha ku Krell amplifier, mabasiwo anakhazikika kwambiri, akuwomba punchier komanso molondola. Kuwomba kumveka momveka bwino komanso kumveka bwino, kumveka bwino ndi kozama, ndipo kujambula kumakhala kosavuta kwambiri kuposa zomwe timamva kuchokera ku Mengyue Mini. Komabe, mawu a Cole amamveka ozizira pang'ono komanso oyerekezera poyerekezera; zomwezo zikugwirizana ndi mawu a Donald Fagen pa Steene Dan a "Aja".
Zotsatira sizodabwitsa; zimagwirizana ndi malingaliro a anthu omwe amavomereza amawonekedwe ofunikira. Koma zotsatira sizinagwirizane ndi zomwe tinkakhulupirira pamene tinkasewera limodzi ndi Dwight Yoakam limodzi ndi Maria McKee, "Ndikandiike Pamphepete mwa Big Sandy." Zojambulazo zimakhala zowala poyambira - m'ma 1980 za digito kuntchito. Koma kupyolera mu Mengyue Mini izo zimamveka bwino, ngati kuti wina watembenuza chigoba chimodzi. Ndipo ngakhale kuti sizowoneka kuti zikusocheretsa, zimakhalanso ndi oomph okwanira kuti zitsulo zolimba zamagetsi zimayendetse bwino. Choncho, subjectively, tonal malire kumatha pang'ono kutopa.
Tikabwerera ku Krell amplifier, mzere wazitsulo unayamba kuwonjezereka, kuwombera, ndikupatsanso zowonjezereka kwa mawu owala komanso gitala.
Album ya David Chesky yoimba komanso yodabwitsa kwambiri, The Body Acoustic , imasonyezanso mosavuta kusiyana pakati pa awiri amps.
