sveiki,

(atsiprašau, kad sukūriau šią temą pirma prie patalpų audiosistemų, prašau moderatoriaus aną ištrinti, neapsižiūrėjau dėdamas)
taigi kaip ir parašiau temos pavadinime, ketinu pirkti naują magnetolą ir mane labiausiai sudomino šios magnetolos alpine CDA-117Ri ir jvc KD-R921(BTE). kaip suprantu abi magnetolos yra kaip ir flagshipai šių firmų single din auto magnetolų srityje. mano didžiausias dėmesys šiuo atveju yra kuo geresnė garso kokybė ir manau neblogai jei yra daug garso reguliavimo galimybių. maga pradzioj naudociau paprastai komponentus jungti, bet ketinu veliau jungti ir nuo stiprintuvo.

Taigi lyginant šiuos magus, tai jie abu turi 24-bit DAC, tiek alpine tiek jvc turi 3 poras linijinių išėjimų, tik alpinos po 4 V, o jvc po 5 V. abu turi daug garso regulavimo galimybiu. skirtumai pagrindiniai kogero yra kad alpina pusantro karto brangesne uz ta jvc modeli ir alpina neturi integruoto bluetootho, taigi norint laisvu ranku irangos tektu ji kadanors pasitaupius veliau nusipirkti, dar tas dalykas, kad alpina turi galimybe i ja deti garso procesoriu, kuris brangus ir neaisku ar bus dedamas.

mano klausimas butu, kuris magas jusu nuomone graziau ir realiau atgroja muzika leidziant komponentus nuo mago arba per stiprintuva, kurio sq geresnė ir ar tiek daug, kad verta mokėti tą kainos skirtumą ar tas skirtumas bus vos išgirstamas?

kitas dalykas apie ta alpina ir ta garso procesoriu, kiek jis svarbus? Kaup surpatau jis veikia kaip equalizeris ir duoda daugiau garso reguliavimo galimybiu? ar pakankamai graziai gros ta alpina be to garso procesoriaus ar gražiau už jvc? o jei idejus garso procesoriu ar is vis geriau grotu uz ta jvc?

pagal specifikacijas atrodytu tas jvc geresnis, be to ten nereiktų pirkinėti tada jokių priedų prie jo ir viskas jame yra už dar mažesnę kainą. Alpina susidomėjau tik tiek, kad buvau girdėjęs, kad jos atseit ypatingai gerai groja? kas nors galit patvirtint?

Dar pateiksiu aprašymus abiejų čia:

Alpinos aprašymas detalesnis, bet geriau įsižiūrėjus į tai kas svarbu, tai JVC daugiau lyg ir visko yra, nors kaina mažesnė.
