Åpen for et fornuftig bud :)
Parasound Halo JC 2 BP er en ren analog forforsterker, og et product av ekte genier. John Curl og CTC builders, hjernene bak Parasound sin berømte JC 1, har utviklet JC 2 BP til å bli den neste legenden. Parasound har klart å oppnå utrolige 116 dB i signal/støyforhold ved å isolere dual-mono kretsene bak 1 cm tykk skjerming. Balanserte inn- og utganger, polaritetsbryter og fjernkontroll er bare en del av den luksus det er å eie en JC 2BP.
Det spesielle med Parasound JC2 BP iforhold til JC2 er at JC2 BP inneholder en bypass funksjon. Les mer om dette i manualen.

Parasound A23+ er en oppgradering fra velkjente A23. Oppgraderingene er i hovedsak større effekt, men også bedre crosstalk, kraftigere trafo, bedre høyttaler terminaler ved siden av den det nye Halo-utseendet.
Parasound Halo A23 stereo forsterker yter 160 watt THX Ultra 2 sertifiserte effekt pr kanal, og den ser like fantastisk ut som den låter. Sofistikert design, høyoppløst lyd, kun deler av beste kvalitet og en overkommelig pris. Parasound har bygget hele sitt omdømme på et klart og detaljert lydbilde i sine forsterkere. Istedenfor å bruke avkoblings-kondensatorer og -spoler som mange andre forsterkerprodusenter, benytter Parasound seg av avanserte DC-servoer. Med sin flotte lyd og sitt vakre utseende, gir Parasound A23 deg alt du forventer av en effektforsterker fra Parasound. Passer perfekt i både et stereo oppsett i en hjemmekino.
