Hi, may new sighting ako Sansui alpha607 is this a good amp ? 6.5k ang asking price. nakita ko sa pier today. does it have digital outs ? Thanks !!

Why are you looking for an amp that have digital outs? What's your purpose?

Kimpao,

Kala ko usap tayo hehehe mamaya ulit usap tayo about sa accuphase ni Sir Akyat hehehe

sige, mga pre pag naayos ko na yung problem sa static... mukhang nasa speaker switch nanggagaling... ayan kasi, hinde nakikinig sa previous owner, sinabi na nga madumi yung speaker switch eh, hehe buti nakahiram ako ng contact cleaner kay pareng karipas.

Sir Av_phile,

Yun nga ang tanong nya sa kin kanina umaga. If this is the case how can we repair it? Can we open the relay or do we have to replace it? If it needs to be replaced, is it ok to look for a replacement or do we need to look for the exact value?

Any suggestion on where can akyat source the component is very much appreciated, since Monday pa nag-iisip si akyat kung pano maaayos yun static... he he he he.

Based on experience, some relays are vacuum sealed to prevent oxidation of contacts.  But they are used in expensive equipment like in commerical aircraft where I used to work.  They can't be opened and must be replaced if inoperable.

The relay switches used on home audio circuits are also sealed but am not sure if evacuated.  Many are the clear see-thru types and can be opened.  You will have to buff the copper contact plates which are very sensitive and delicate with a high risk of ruining them.   I suggest you visit Deeco or some beter electronic shops in Raon and ask for speaker relay switch or microswitch.  These relays are either voltage or current activated so you will need to know what the ratings are in the relay switch you will replace.   Better still, dislodge the offending relay and bring it with you when canvassing for a new one in Raon.  

You could ofcourse bridge or short the contacts, thus bypassing the amplifer protection circuit.  I am just not so sure how complicated the circuitry is in the Accuphase amp to safely do this.

Sir philander, sorry nagkamali lang, tanong ko pala is kung may digital input  
Sir akyat, oo nga sobra mahal, sa tingin mo which is better the sansui alpha 607 or the denon pma-780d ?
Which would you buy ?Thanks !!!

Are you absolutely certain it's the speaker relay switches that are at fault?  Why don't you have a good technician look at it first.  You may have some loose grounding somewhere.  Speaker relay switches are often very well built and robust especially in hi end gears.  how old na ba are the amps?  Is it the same for both channels?  For both speakers A and B?

know what?  i may be wrong about the speaker switch..  just this morning i was playing the amp and switched speaker A & B several times -- there was no problem at all.

it is during these times that i notice how good it sounds.. some complex tracks which sound "confused" and bright on other amps sound natural on this amp.

last night i played it for 4 hours continuously with no problems.. then i went out for a while, and when i came back, i turned on the amp, played a CD, and there it was again, that annoying static sound.. in the morning it was gone.

the previous owner said he hasn't experienced this static sound.. so i'm wondering if it's eating up so much current (power consumption: 830W) that i really need to put it in a separate outlet?  its kinda sharing the same outlet as my 32" TV, DVD player and others.. but i thought it doesn't consume very much when i'm not playing loud.

better have you amp on its own separate outlet.

oonga bro. baka para yan ung rotel amp ko where the manual suggests to have its own outlet. no sharing allowed-parang eat all you can anoo

hans, baka hindi lang static lumabas dun.... pati usok!  

"Goodbye akyatbundok. I already have a new home. New Speakers to drive. A new team mate receiver. Hope my new master won't overdrive me and won't connect a hard-to-drive speakers to me."

- SONY ES AMP.

congrats nels, ok yan...pinakawalan din ha

Narayan,

Thanks.

- This Amp will be my dedicated Stereo Set-up
- Will power my 2 Surround Back.
- Will power my Outdoor setup during parties and every new year's eve.

Ano kaya ang susunod na pakakawalan sana yong   ;Dpara ako naman

sir akyat, Thanks !!

Is this amp pure class A?  If not, i would be so brash to suggest you leave it on always once you get the occasion to hear it's ok.  Power consumption won't be that much when idle if not class A.  Just to let you know, many audiophiles never turn off their gears unlesss they go on extended vacation.  

Yup, you can assume it eats around 100 to 150 watts at low volumes, except durig peak musical transients when the consumption can be instantaneously higher, even double. Is your VU meter average or peak indicating?  

It's obviously not class A.  I would say 60 watts power conumsption when idle is OK  So you can leave it ON all the time unless you're out for long periods.  

First Impression sa Sony ES Amp.

IMHO, i found this amp neutral sounding connected to my MS 902 and having a VCD/CD Player as the source.

Haven't connected though to my MS 912.

And also this AMP does not get hot easily compared to my Kenwood Receiver on stereo use.

Better dynamics or should I say full-bodied ang sound compared to the 9060D on stereo.

I thought the clipping would be solved when I change AMP. Hindi pala. Still I am not comfortable to listen to high volume. Anyway, this SONY ES - MS 902 is set up in my room (3m x 3m). I hope harshness will be gone when I move the set up to the Sala next month.
