    I need some help please as I fried my 5 year old str db930 saturday night ( boy was it hot!!!!) so took it down to my local sony dealer who offered me a str db 790 in part ex or depending on the repair cost.....for 180.00 

    My questions are, is the 790 a better amp than my 930, or should I wait for the 795 or upgrade to a 2000?

    Sony UK confirmed the 795 doesn't have a DAB tuner, so quite how WHFI tested it is stange!!!

    My current set up is a dvp 725d player, (dead str db 930, soon to be repaired or replaced) b&w 603s front speakers, b&w cc3 centre, kef q80 rears, sony wega 36" tv, sony dv3 $ky digibox, all cabled with qed silver cables.

    Oh my god.  A question about a 930 and I got in before MAXX, he must be drunk or have a power blackout

    This site is full of people who love the STRDB930, its amplification was a rare gem from Sony. Although the newer recievers have a few more tricks to them, the amplification is generally regarded to be inferior.

    I would personally go to the 2000 range if you can manage it, the 790 or 795 is not (IMHO) as good as your 930 or the 2000 stuff.

    Others will be tuning in soon, I'm sure!

    Wow, I too got in before Maxx...

    The DB930 was the top QS receiver back in it's day, and the DB2000 should be it's equivalent now. I would consider switching to a 790 a downgrade.

    I agree with Craig and Tiny that moving on to the DB 2000QS with its Digital amplification would be the best alternative you have at this point.

    As far as Analog Receivers go the DB 930QS with its Home Theater Choice benchtested 93 wpc @ .013% THD 25-20khz out performed not only the DA 555ES which benchtested at 76 wpc @ .02% THD 25-20k hz, but also all of the Sony ES Receivers which they benchtested for several years afterwards.

    Its too bad that your DB 930QS fried, but I think that you will be very pleased with the smooth and detailed sound of the DA 2000ES as well as its advanced processing capabilities.

    Craig- At the time of your post on this thread it was 5:30 am here on the west coast and I was sound asleep dreaming up ways of tweakig my Audio system.

    Guy's

    Thanks for your help and advice, I am still cross with myself for pushing the "old girl" so hard.
     
    I appreciated the comments and will upgrade to a STR DB200 QS S master if the repair costs of the 930 prove to high.

    Maxx you mention the DA2000 ES as a replacement, I have a UK 2003/2004 product brochure and this model is not mentioned, is this a new model or shall I stick with the above?

    Regarding the 930, it was running for about 4 hours, then all the front leds lit up at once for a couple of seconds then nothing. any clues?
     
    Thanks

    LOL Maxx.  Some people would call HT dreams a nightmare.
    I can picture people having nightmares about being strangled by a mess of cords and buried under a mountain of instruction manuals.

    The rest of us do that for fun

    cdj- When I said DA 2000ES (the North American model) I meant DB 2000QS (the European model).

    I think the new 2004-2005 European models will be the DB 900QS and DB 1000QS, but there is not much information on them yet.

    Craig- Strange lot aren't we? I have actually dreamt about doing an upgrade on my Audio system and later woken up and applied it. A few times it has even worked!

    Thought I'd let you know my local sony dealer has come back and they can repair my 930....
     
    They have loaned me a db2000 qs to compare and I must say I cannot hear much difference betweem them, so I guess I will be getting the 930 repaired..(M axx you were right the 930 is one hell of an amp....)

    Great site guy's, next time I need help which could be quite soon!!!!(when in the dealer's I saw the new 37" kde p37xs1 plasma and 37 "lcd and got a very strong urge to bin the tv and get a new screen).

    Many thanks agian

    That's great news Chris! The DB 930 is well worth keeping. It has a supurb build quality that not only includes ES grade push-pull output amps, but also high quality Nichicon Gold Tune capasitors throught.

    PLease keep in touch ad let us know how the repair goes.

    Maxx it will be back on Friday with a new mains transformer.....

    However I have a question, I dug out the manual for the 930 whilst it is in for repair and it states when using the A+B speaker setting (this was the config when the amp blew, could it have been the cause for the mains transformer to blow?) the ohm setting should be switched from 8 to 4 ohms, can any body explian why.

    My speaker set up is: A =  b&w 603s3 and B = Mission M70, both pairs of speakers are 8 ohms?

    Assuming that the impedance of both sets of speakers (A & B) is 8 ohms, the impedance presented to the left and right channel amps is 4 ohms.  If the impedance of either set of speakers is less than 8 ohms, the impedance presented to the amps will be even lower.  That's why you need to place the speaker impedance switch in the 4 ohm position.

    If you want to run two sets of front speakers and you want your Music at live concert levels and your Movies at Theater volume, I would suggest adding a 2 channel Creek, NAD or Adcom amplifier to the preamp outputs of the DB 930 to run the second set of speakers. This will give you all of the volume you desire without exceeding the maximum amount of power that the DB 930 was designed to generate or resorting to using the current limiting circuitry that using the 4 ohm switch engages.

    You are wise in seeking ways to prevent the DB 930 from going into meltdown again and adding an outboard 2 channel amp
    for the second set of front speakers would add years of life to your newly repaired DB 930. Take good care of it because Sony will probably never make another Analog Receiver with that level of build quality again.
