From experience, effective ang a907 series mag-drive ng big woofers -- 15-inch types. Kaya nuon JBL-4430 (now bi-amped with a pair of Sansui AU-X11s) ang nakakabit sa a907iMos ko. Ngayon yung Technics SB-7000 na. Maganda rin ang resulta. Kayang-kaya niyang palabasin yung deep bass ng big woofers di tulad ng iba kong amplifiers, even those rated 160wpc and above in RMS, parang bitin mag-drive ng big woofers.

  Dapat po pala JBL L series ang hanapin ko. Nagkaroon ako ng Dynaudio Audience 60 di nagmatch kaya binitawan ko, sa ngaun B&W 602 S3 ang gamit ko sa a907.

Anak ng putakte..hehehe…ung technics ko na 8080a nagtampo ata , naghahanapn daw kasi ako ng technician lol

Kanina while playing around 40-60mins at 10oclock vol biglang nawala ung sounds sa speaker – hindi naman mainit ung amp
nakaON pa din naman ung amp and cd player was still playing

pinatay ko den lumabas ulit ung sounds then parang pumupunta sya sa protect mode…after a minute

so ginawa ko pahinga after 30mins played Olivia ONG songs nakatapos ng 5songs then nagpalit ako ng cd – craig david – nawala ulit ung kanta
usually I use the amp more than 5hours  pero now ko lang naexp to hehe..

so turn off and on nagprotect mode ulit
so what I did was to  there was a setting sa amp    DC and LOW CUT 2hz
always naka DC si MAIN – theres a light indicator for DC
binaba ko sya sa LOW Cut then everything was fine I played for 30mins kaya lang papunta na ako office…bukas ko ulit kalikutin…bakit kaya..??

any opinion guys? salamat

I'm not sure bro, pero yun DC was supposed to be for Direct Control sa main amps which means for pre-amp bypass, merun din ako amp dati na Vintage Onkyo Integra na merun din DC servo na nasa clipping control section naman. Yun LOWCUT naman ang pag kakaalam ko sa pre-amp LOW & High's filtering in the other terms is "Subsonic Filter"... Wait lang tayo sa mga Master of Vintage gear for further explanation sa concern mo bro. ;)

Nice to hear bro... congrats, hehee... :)


bro vhinx

Yup mag kaiba sila, yun Lowcat for pre-amp filtering na pag switch mo sya ay mag change freq yun Low and/or even high's... Yun DC if I not mistaken use for source direct to the main amp (at hindi na dadaan pa sa pre-amp which is tone control - BASS & TREBLE)...

mga braders, need your comments pls.
napadaan ako kanina sa isang japan surplus shop, may nakita akong sansui AU alpha555 and a marantz PM90. I tested the PM90, kya lang di maganda yata condition ng speakers, pero good sounding pa rin,  they are selling for 7500. does anybody knows kung magkano na dapat ang price nito, considering this is a 1991 release., sinubukan kung buhatin, nabigla ako, super bigat pala. 27kg

Sir kunin niyo na iyung Marantz. Kapag iba iyan baka wala na iyan. Mahirap mag-testing ng maayos sa mga surplus shops kaya hindi magandang basehan listening test doon. Kahit pa siguro nasa 8k hanggang 10k kukunin ko iyan.
